Suppose that an individual has a utility functions given by: U(X,Y)=3X 2
+Y 2
Suppose also that the individual has an income of $1500, the price of X is $8 per unit, and the price of Y is $18 per unit. What is the utility maximizing Quantity of X ?

Answers

Answer 1

The utility-maximizing quantity of X is approximately 321.43 units.

To determine the utility-maximizing quantity of X, we need to find the point where the individual's budget constraint is tangent to the indifference curve, representing the highest possible utility given the prices and income.

The individual's budget constraint is given by:

Income = Price of X * Quantity of X + Price of Y * Quantity of Y

Substituting the given values:

$1500 = $8 * Quantity of X + $18 * Quantity of Y

We can rearrange this equation to solve for Quantity of Y:

Quantity of Y = ($1500 - $8 * Quantity of X) / $18

Now, let's express the utility function in terms of only X using the quantity of Y derived above:

U(X) = [tex]3X^2 + ([$1500 - $8 * Quantity of X] / $18)^2[/tex]

To find the utility-maximizing quantity of X, we can take the derivative of the utility function with respect to X and set it equal to zero:

dU/dX = 6X - (2 * $8/$18) * ([$1500 - $8 * X] / $18) = 0

Simplifying the equation:

6X - (16/18) * (1500 - 8X) = 0

6X - (8/9) * (1500 - 8X) = 0

6X - (8/9) * 1500 + (8/9) * 8X = 0

6X - (4/3) * 1500 + (8/9) * 8X = 0

(8/9) * 6X + (8/9) * 8X = (4/3) * 1500

(8/9) * 14X = (4/3) * 1500

X = (4/3) * 1500 * (9/8) / 14

Solving the equation, we find:

X ≈ 321.43

Therefore, the utility-maximizing quantity of X is approximately 321.43 units.

Answer 2

The utility-maximizing quantity of X is approximately 0.0221 (rounded to the appropriate decimal places).

To find the utility-maximizing quantity of X, we need to maximize the individual's utility function subject to the given income constraint and prices of X and Y.

Write down the individual's utility function:

U(X, Y) = 3X^2 + Y^2

Write down the budget constraint:

Total expenditure = Income

Price of X * Quantity of X + Price of Y * Quantity of Y = Income

Plugging in the given values:

$8 * Quantity of X + $18 * Quantity of Y = $1500

Solve the budget constraint for Quantity of Y:

Quantity of Y = ($1500 - $8 * Quantity of X) / $18

Substitute the expression for Quantity of Y into the utility function:

U(X, Y) = 3X^2 + [(1500 - 8X) / 18]^2

Differentiate the utility function with respect to X to find the critical point(s) that maximize utility:

dU(X) / dX = 6X - (16 / 81) * (1500 - 8X) / 9

Simplify the equation:

dU(X) / dX = 6X - (16 / 729) * (1500 - 8X)

Set the derivative equal to zero and solve for X:

6X - (16 / 729) * (1500 - 8X) = 0

Simplify and solve for X:

6X - (16 / 729) * 1500 + (16 / 729) * 8X = 0

4374X - 32X + 96 = 0

4342X = -96

X = -96 / 4342

X ≈ -0.0221 (disregard the negative value)

Evaluate the quantity of X at the critical point:

Quantity of X ≈ -0.0221

Since we cannot have a negative quantity of X, we conclude that the utility-maximizing quantity of X is approximately 0.0221 (rounded to the appropriate decimal places).

Answers

Business decision-making is the process of identifying the most profitable course of action for a business. There are two basic approaches to making business decisions: common sense and scientific approaches. Scientific decision-making is based on the hypothesis-testing model that is used in the scientific method.

Common sense is an intuitive and practical approach to decision-making that is primarily based on personal experience, instincts, and gut feelings. It is a quick and easy way to make decisions without the need for extensive research. For example, a retail store owner may decide to stock up on winter clothing in the winter season because he or she knows that winter is the time when people buy more winter clothes. Scientific decision-making, on the other hand, is a data-driven and analytical approach to decision-making. Scientific decision-making is also more comprehensive and rigorous than common sense decision-making since it requires the use of specialized tools, techniques, and knowledge. Nonetheless, common sense decision-making has its advantages too. It is simple, quick, and cost-effective. In situations where time is limited, or resources are scarce, common sense decision-making may be the only option available.

In conclusion, it is clear that both common sense and scientific decision-making have their pros and cons. However, businesses that want to achieve long-term success should consider using a scientific approach to decision-making as it is more reliable, accurate, and objective.

A company is in the process of constructing a new plant at a cost of $20 million. It expects the project to generate cash flows of $10 million, $6 million, and $10 million over the next three years. The cost of capital is 18.6 percent p.a. What is the net present value of this project? (in millions to three decimals) a. $-1.308 b. $38.692 c. $−4.240 d. $−0.515

Answers

The net present value (NPV) of a project is the difference between the present value of cash inflows and the present value of cash outflows. To calculate the NPV, we need to discount the cash flows at the cost of capital. The correct answer is d. $−0.515.


In this case, the cash flows are $10 million, $6 million, and $10 million over the next three years. The cost of capital is 18.6 percent per annum.



To calculate the present value of each cash flow, we use the formula: PV = CF / (1 + r)^n, where PV is the present value, CF is the cash flow, r is the discount rate, and n is the number of years.

PV1 = $10 million / (1 + 0.186)^1 = $8.445 million
PV2 = $6 million / (1 + 0.186)^2 = $4.370 million
PV3 = $10 million / (1 + 0.186)^3 = $6.292 million


Next, we sum up the present values of the cash flows and subtract the initial cost of the project to find the NPV:

NPV = PV1 + PV2 + PV3 - Cost of the project
NPV = $8.445 million + $4.370 million + $6.292 million - $20 million
NPV = $−0.893 million


Therefore, the net present value of this project is -$0.893 million (to three decimals).

The correct answer is d. $−0.515.

If you have Mexican pesos, what is the number of pesos that you need to exchange for $20,000 ?

Answers

The equilibrium UK interest rate is approximately 0.33% based on the interest rate parity equation.

To exchange 1,000 pounds, you would need $1,403, based on the bank's ask quote (GBP/USD).

To exchange $20,000, you would need approximately 142,857.14 pesos, based on the bank's bid quote (MXN/USD).

To calculate the equilibrium UK interest rate, we can use the interest rate parity equation:

(1 + i₄) = (1 + i₃) × (Fₚ / Sₚ)

Where i₄ is the UK interest rate, i₃ is the US interest rate, Fₚ is the forward rate of the pound, and Sₚ is the spot rate of the pound.

Given:

US interest rate (i₃) = 3.13%

UK interest rate (i₄) = ?

Forward rate of the pound (Fₚ) = $1.816

Spot rate of the pound (Sₚ) = $1.866

(1 + i₄) = (1 + 0.0313) × (1.816 / 1.866)

(1 + i₄) = 1.0313 × 0.97265

(1 + i₄) ≈ 1.003255

i₄ ≈ 0.003255 * 100

i₄ ≈ 0.3255%

Therefore, the equilibrium UK interest rate is approximately 0.33%.

To calculate the amount of dollars needed in exchange for 1,000 pounds, we can use the ask quote (GBP/USD) provided by the bank:

Ask quote (GBP/USD) = 1.403

Amount in dollars = 1,000 pounds × 1.403 USD/GBP

Amount in dollars = $1,403

Therefore, you would need $1,403 in exchange for 1,000 pounds.

To calculate the number of pesos needed to exchange for $20,000, we can use the bid quote (MXN/USD) provided by the bank:

Bid quote (MXN/USD) = 0.140

Number of pesos = $20,000 / 0.140 MXN/USD

Number of pesos ≈ 142,857.14 pesos

Therefore, you would need approximately 142,857.14 pesos to exchange for $20,000.

Assuming that the substitution effect dominates the income effect, does this trade policy create
more employment and welfare? Explain and provide a graph

Answers

Analyzing the effects of imposing a tariff, specifically Trump's proposal, on an open economy with importable goods and exportable goods can be done by considering the utility function, production function, and budget constraints.

In this one-period economy with balanced trade (NX = 0), the representative consumer's utility function is U = U(Cm, l), where Cm represents consumption of the importable good and l represents leisure. The economy produces only an exportable good using the production function Yx = zF(K, Nd), where z represents productivity, K represents capital, and Nd represents labor. The consolidated budget constraint is Cm = w(h - l) + π - T, where w represents the wage rate, h represents total time endowment, π represents profits, and T represents taxes. Profits are given by π = pxYx - wNd, where px represents the terms of trade (relative price of exportable goods in terms of importable goods). Now, let's assume that the government imposes a tariff 0 < τ < 1 on importable goods. The new constraint becomes (1+τ)Cm = w(h - l) + π - T and the government balances its new budget constraint with G = T + τCm. To analyze the effects on employment and welfare, we need to consider the substitution effect and income effect. If the substitution effect dominates the income effect, then the trade policy could potentially create more employment and welfare. To visualize this, we can use a graph. On the horizontal axis, we can represent the quantity of labor (Nd), and on the vertical axis, we can represent the wage rate (w). With the imposition of the tariff, the new budget constraint shifts outward, indicating an increase in the consumption of the importable good. This leads to an increase in profits (π) and potentially higher wages (w) as well. If the substitution effect dominates, the wage rate could increase further due to the higher demand for labor. This would lead to more employment and potentially higher welfare. However, it is important to note that this analysis assumes that the substitution effect dominates the income effect. The actual impact on employment and welfare would depend on various factors such as the magnitude of the tariff, the elasticity of demand for the importable good, and the response of the economy to the trade policy.

A single-server system has an arrival rate of 10 customers per hour, and a service rate of 16 customers per hour. Both rates are Poisson distributed. a. What is the system utilization? (Round your answer to 2 decimals.) P b. What is the average number of customers waiting for service? (Round your answer to 2 decimals.) La customers c. What is the average time customers wait in line for service? (Round your answer to 3 decimals.)

Answers

The system utilization is 62.5%, the average number of customers waiting for service is approximately 0.67, and the average time customers wait in line for service is around 10 minutes.

A. The system utilization can be calculated using the formula:

Utilization = Arrival rate / Service rate

In this case, the arrival rate is 10 customers per hour and the service rate is 16 customers per hour. Plugging these values into the formula, we get:

Utilization = 10 / 16 = 0.625

Therefore, the system utilization is 0.625 or 62.5%.

B. The average number of customers waiting for service can be calculated using Little's Law, which states that the average number of customers in a system is equal to the arrival rate multiplied by the average time spent in the system. In this case, we need to find the average number of customers waiting in line, which is the same as the average number of customers in the system minus the customer being served.

The average number of customers in the system can be calculated as:

The average number of customers in the system = Arrival rate / (Service rate - Arrival rate)

Plugging in the given values, we get:

Average number of customers in the system = 10 / (16 - 10) = 10 / 6 = 1.67

Therefore, the average number of customers waiting for service is 1.67 - 1 = 0.67 or approximately 0.67 customers.

C. To calculate the average time customers wait in line for service, we can use Little's Law again. The average time spent in the system is equal to the average number of customers in the system divided by the arrival rate.

Average time spent in the system = Average number of customers in the system / Arrival rate

Plugging in the values we found earlier, we get:

Average time spent in the system = 1.67 / 10 = 0.167 hours or approximately 10 minutes

Therefore, the average time customers wait in line for service is approximately 10 minutes.

How each country can take advantages of industrial symbiosis/ecology to reduce environmental issues (such as global warming, greenhouse gas,,...)
Please, give detail explanations for the way industrial symbiosis can do.

Answers

Industrial symbiosis, also known as industrial ecology, is an approach that promotes collaboration and resource sharing among different industries to reduce environmental issues. Here's how each country can take advantage of industrial symbiosis to tackle environmental challenges such as global warming and greenhouse gas emissions:

1. Resource exchange: Industrial symbiosis encourages the exchange of by-products, waste materials, and energy between industries. For example, one industry's waste product can be utilized as a raw material by another industry, reducing the need for new resources and minimizing waste disposal. This resource exchange helps in conserving natural resources and reducing the environmental impact of industries. 2. Co-location of industries: By locating industries with complementary needs and outputs close to each other, countries can facilitate symbiotic relationships. This proximity enables efficient transportation of materials, reduces transportation-related emissions, and creates opportunities for collaboration and resource sharing. 3. Energy efficiency: Industrial symbiosis promotes the use of energy-efficient technologies and practices. For instance, industries can collaborate to establish shared energy infrastructure, such as cogeneration plants, where waste heat from one industry can be utilized by another industry. This not only reduces energy consumption but also minimizes greenhouse gas emissions. 4. Waste reduction and recycling: Through industrial symbiosis, countries can promote waste reduction and recycling practices. By exchanging waste materials, industries can find alternative uses for these materials, thus reducing the need for landfilling or incineration. This approach helps in minimizing pollution and conserving natural resources. 5. Innovation and research: Industrial symbiosis fosters innovation and research by encouraging collaboration and knowledge-sharing among industries. This collaboration can lead to the development of new technologies, processes, and business models that are more environmentally friendly. By leveraging each other's expertise, countries can accelerate the transition towards a more sustainable industrial sector. Overall, industrial symbiosis provides a framework for countries to address environmental issues by promoting collaboration, resource efficiency, and waste reduction among industries. By implementing these principles, countries can minimize their environmental footprint and contribute to global efforts to combat climate change and other environmental challenges.

Calculate the equivalent monthly effective interest rate if the
3-month effective interest rate is 9%.

Answers

The equivalent monthly effective interest rate, when the 3-month effective interest rate is 9%, is approximately 2.8%.

To calculate the equivalent monthly effective interest rate, we need to use the formula:

[tex]\( (1 + r)^n = (1 + i) \)[/tex]

Where:

- [tex]\( r \)[/tex] is the monthly effective interest rate,

- [tex]\( n \)[/tex] is the number of months, and

- [tex]\( i \)[/tex] is the given 3-month effective interest rate.

In this case, we are given a 3-month effective interest rate of 9%. To find the equivalent monthly effective interest rate, we solve for [tex]\( r \)[/tex] in the equation:

[tex]\( (1 + r)^3 = (1 + 0.09) \)[/tex]

First, we calculate the right side of the equation:

[tex]\( (1 + 0.09) = 1.09 \)[/tex]

Next, we take the cube root of both sides to isolate [tex]\( r \)[/tex]:

[tex]\( (1 + r) = \sqrt[3]{1.09} \)[/tex]

Finally, we subtract 1 from both sides to find [tex]\( r \)[/tex]:

[tex]\( r = \sqrt[3]{1.09} - 1 \)[/tex]

Using a calculator, we can find that [tex]\( r \)[/tex] is approximately 0.028, or 2.8%. Therefore, the equivalent monthly effective interest rate, when the 3-month effective interest rate is 9%, is approximately 2.8%.

What is loss avervion? 10) Suppose Thomas has routinely received a $1500 merit raise at the end of each year while Mart has received a $3000 raise for as long as she can remember. Draw their responses if each receives a $2500 rake this year uning the value function: v(x)=x for gains and v|ve = 2x for losses. What if they each receive a $3500 rase this year? How do these functions indicate losir aversion? 11) Standard economics assumes preferences and ind therence curves are independent of current endowment or reference point fie, where you are starting fromi. a. This means the indelerence curve is b. Let's take the following situation to show how loss averyon violates this assumption. Suppose the value function for a consumer is silt v(x)=x for gains and v∣p∣+2x for losses and that these functions represent preferences for both good x and good y. Further suppose that the consumer starts with an endowmert of (Ex)=(4,2). Draw an inditerence curve for this person. Then show that the indifference curve is not reversible. 12) Usine the concepts of Wilineness to Pay (WTP) and Walingness to Accept (WTA), whar is the Endowment Effect?

Answers

Loss aversion: It is a behavioral bias that refers to the fact that losses are more impactful than gains. It is a person's tendency to avoid losses rather than acquire gains.

Thomas's  values the $1500 raise less than Mart values the $3000 raise. And when they receive a $2500 raise, both have positive gains, and their responses will be the same. They will have the same attitude towards the money, so both will be satisfied.

Now, when they each receive a $3500 raise, both have positive gains, and Thomas will have a better response than Mart because he will have more money than usual. The function v(x)=x represents Thomas's and Mart's preferences for good x, and it shows that they are more likely to accept gains than losses.

11) Conventional economics makes the assumption that preferences and indifference curves are unaffected by your present financial situation or starting position. The indifference curve is hence vertical. When the value function for a consumer is v(x)=x for gains and vp+2x for losses, and it reflects preferences for both good x and good y, loss aversion contradicts this premise.

It is when the consumer starts with an endowment of (Ex)=(4,2).The indifference curve for this person is a curve that slopes upward and is steeper for losses than gains. The indifference curve is not reversible because the slope is steeper for losses than for gains.

12) Endowment Effect: It is a behavioral bias that occurs when people tend to place a higher value on things they own than on identical things that they do not own. Willingness to Accept (WTA) is the minimum amount a seller is willing to accept for a product or service. The endowment effect occurs when WTP is lower than WTA.

Answers

Android phone market:

Long-run average cost (LAC) is minimized at 300. Minimum average cost is $150 per unit. The total market demand is given by Q = 15,000−50P.

a) What is the Android phone market's long-run supply curve?

When the cost is equal to the minimum average cost ($150 per unit), the long-run supply curve would begin and continue horizontally at that cost. Thus, the long-run supply curve for Android phones is Q = 150/50 = 3,000 units.

b) What is the long-run equilibrium price (P*) and total industry output (Q*)?

How many companies are competing in this market?

In the long run, the Android phone market will have a supply of 3,000 units, as computed above.

In the long run, price would be equal to minimum long-run average cost of $150 per unit.

Using the demand function, P* = $9,750/15,000 = $0.65 per unit.Q* = 15,000 - 50(0.65) = 11,750 units

Thus, 11,750/3,000 = 3.92 firms would compete in this market.

Since we cannot have a fraction of a firm, there would be four companies competing in this market.

c) The short-run total cost curve for each firm is given by STC = 0.5q2 - 150q + 20000,

where q is the firm's production quantity.Find the short-run marginal cost (SMC) for each firm. What is the market short-run supply curve?We differentiate the STC with respect to Q to get SMC, which is the marginal cost of each firm:SMC = d(STC)/d(Q)= d/d(Q)[0.5q2 - 150q + 20000]= q - 150

Let Qs be the short-run supply, and let there be n firms operating in the short-run. Since the industry is competitive, each firm will produce until P=SMC.

Using the demand function and the SMC that was calculated earlier, we will solve for the quantity at which P=SMC:0.65 = Q/n - 150The equation above gives us the short-run supply curve.

d) Suppose Android phone has become more popular and the market demand curve shifts outward to Q=20,000−50P. In the short-run, find the new equilibrium price.

Answers

Lower marginal tax rates on married couples encourage higher labor force participation rates by the secondary income earner. The Correct option is C

Lower marginal tax rates on married couples encourage higher labor force participation rates by the secondary income earner is the way in which changes in marginal tax rates on married couples affect labor force participation rates.

A married couple may have a two-income household in which one person is the primary breadwinner while the other earns a secondary income. Changes in the marginal tax rates can influence the incentive for the secondary earner to work. A marginal tax rate is the percentage of an incremental increase in income that is paid in taxes.To support a family and make ends meet, both spouses may need to work.

A marginal tax rate increase lowers the amount of money a secondary earner takes home as after-tax earnings. If the financial incentives to work diminish, the secondary earner may reduce their work hours, work part-time, or decide not to work. Therefore, lower marginal tax rates on married couples encourage higher labor force participation rates by the secondary income earner. The Correct option is C

The net operating cash flows from the expansion project at the end of year 1, 2, 3, 4 and 5 are estimated to be $42,350, $47,024, $94,752, $82,512 and $120,456 respectively.
Biogen has a weighted average cost of capital of 28%.
_______________________________________________
What is the modified internal rate of return if Biogen undertakes this project? Assuming that the positive cash inflow from undertaking this project will be reinvested at the weighted average cost of capital.
24.63%
27.16%
22.82%
20.04%

Answers

The modified internal rate of return (MIRR) is approximately 27.10%, which is closest to 27.16%. Therefore, the correct option is 27.16%.

To calculate the modified internal rate of return (MIRR), we need to determine the present value of the cash inflows and outflows using the weighted average cost of capital (WACC) as the discount rate. Then we can find the discount rate that equates the present value of cash inflows to the present value of cash outflows.

First, let's calculate the present value (PV) of the net operating cash flows using the WACC of 28%:

PV(year 1) = $42,350 / (1 + 0.28)^1 = $33,007.81

PV(year 2) = $47,024 / (1 + 0.28)^2 = $32,552.34

PV(year 3) = $94,752 / (1 + 0.28)^3 = $55,195.99

PV(year 4) = $82,512 / (1 + 0.28)^4 = $39,098.86

PV(year 5) = $120,456 / (1 + 0.28)^5 = $48,919.82

Next, calculate the present value of the initial investment:

PV(initial investment) = -$238,200

Now, calculate the future value (FV) of the positive cash inflows reinvested at the WACC:

FV(year 1-5) = $33,007.81 * (1 + 0.28)^5 + $32,552.34 * (1 + 0.28)^4 + $55,195.99 * (1 + 0.28)^3 + $39,098.86 * (1 + 0.28)^2 + $48,919.82 * (1 + 0.28)^1 = $315,405.28

Finally, calculate the MIRR by finding the discount rate that equates the present value of cash outflows to the future value of cash inflows:

MIRR = ((FV inflows / PV outflows)^(1/n)) - 1

= ((315,405.28 / -238,200)^(1/5)) - 1

= (1.32459)^(0.2) - 1

≈ 0.27099

The modified internal rate of return (MIRR) is approximately 27.10%, which is closest to 27.16%. Therefore, the correct option is 27.16%.

Externalities refer to the positive or negative impact of economic transactions on people other than the buyer or seller involved in the transaction.

In this scenario, it is assumed that there are positive externalities from consuming measles vaccines.Market (inverse) demand for measles vaccine is given by:P = 100 - 2QMarket (inverse) supply for measles vaccine is given by:P = 10 + 0.5QWhere:P is the unit price of measles vaccine, andQ denotes the quantity.

Marginal external benefit is given by:MEB = 0.5QThe size of the deadweight loss from the market equilibrium is given by the formula:0.5 x ([a] - [b]) x (0.5 x [c]) = [d]To obtain the values of [a], [b], and [c], we need to equate the market demand and supply equations to obtain the equilibrium quantity and price:

Market demand: P = 100 - 2Q

[tex]Market supply: P = 10 + 0.5QSolving for Q:100 - 2Q = 10 + 0.5Q89 = 2.5QQ = 35.6Substituting[/tex]

Q = 35.6 into the demand and supply equations to obtain P:Market demand: P = 100 - 2Q = 100 - 2 x 35.6 = 28.8Market supply: P = 10 + 0.5Q = 10 + 0.5 x 35.6 = 27.8T

Answers

The ROE for firm O is higher than that of firm C because it is more profitable.

The DuPont equation is used to identify why the ROEs of four different firms are different. The following are the selected financial data for the four firms

:​ROE = Net Income / Shareholder's Equity​

Return on Equity (ROE) = Profit Margin (Net Income / Sales) × Asset Turnover (Sales / Assets) × Financial Leverage (Assets / Equity)

Let's evaluate each statement one by one to determine whether it is true or false.

i. The ROE for firm B is higher than for firm D because B uses more leverage.

This statement is true. The ROE formula is a product of three key ratios, which include profit margin, asset turnover, and financial leverage. Financial leverage is measured by the company's debt-to-equity ratio. Firms that use more leverage will have a higher ROE. Therefore, the ROE for firm B is higher than that of firm D because B uses more leverage.

ii. The ROE for firm A is higher than for firm B because A has higher asset turnover. This statement is false. Asset turnover is measured by sales divided by assets. It indicates how efficiently a company is using its assets to generate sales. A high asset turnover ratio implies a better utilization of the company's assets. Asset turnover affects ROE, but it doesn't always imply a higher ROE. Other factors, such as profit margins and financial leverage, can affect the ROE of a company. Therefore, the ROE for firm A is not higher than that of firm B because A has higher asset turnover.

iii. The ROE for firm O is higher than for firm C because this move profitable. This statement is true. Profit margin is a measure of how efficiently a company generates profits from its sales. It is the difference between sales and costs divided by sales. Profitable firms usually have a higher profit margin. Therefore, the ROE for firm O is higher than that of firm C because it is more profitable.

But his thoughts were bent on conquest of another kind; he was determined to overthrow an error which designing and interested men had craftily instilled into the civilized world, - a belief in the natural inferiority of the Negro race. It was the glory and the warrantable boast of Toussaint that he had been the instrument of demonstrating that, even with the worst odds against them, this race is entirely capable of achieving liberty and of self-government. He did more: by abolishing caste he proved the artificial nature of such distinctions, and further demonstrated that even slavery cannot unfit men for the full exercise of all the functions which belong to free citizens. 1 1-Find centroid of the channel section with respect to x - and y-axis ( h=15 in, b= see above, t=2 in): 6.
