The solution to the non-homogeneous difference equation with initial conditions Yₙ₊₂ - Yₙ₊₁ - 2Yₙ = 84n, Y₀ = 1, and Y₁ = -3, is:Yₙ = -4(2ⁿ) + (-1)ⁿ - 4n + 1.

To solve the non-homogeneous difference equation with initial conditions Yₙ₊₂ - Yₙ₊₁ - 2Yₙ = 84n, we can follow these steps:

Step 1: Solve the corresponding homogeneous equation
To find the solution to the homogeneous equation Yₙ₊₂ - Yₙ₊₁ - 2Yₙ = 0, we assume a solution of the form Yₙ = λⁿ. Substituting this into the equation, we get:

λⁿ₊₂ - λⁿ₊₁ - 2λⁿ = 0

Dividing through by λⁿ, we have:

λ² - λ - 2 = 0

Factoring the quadratic equation, we get:

(λ - 2)(λ + 1) = 0

So the roots are λ₁ = 2 and λ₂ = -1.

Therefore, the general solution to the homogeneous equation is:

Yₙ = A(2ⁿ) + B((-1)ⁿ)

Step 2: Find a particular solution for the non-homogeneous equation
To find a particular solution for the non-homogeneous equation Yₙ₊₂ - Yₙ₊₁ - 2Yₙ = 84n, we assume a particular solution of the form Yₙ = An + B. Substituting this into the equation, we get:

A(n + 2) + B - A(n + 1) - B - 2(An + B) = 84n

Simplifying and collecting like terms, we have:

-2A = 84

Therefore, A = -42.

Step 3: Apply initial conditions to find the values of A and B
Using the initial conditions, Y₀ = 1 and Y₁ = -3, we can substitute these into the particular solution:

Y₀ = A(0) + B = 1
B = 1

Y₁ = A(1) + B = -3
A + 1 = -3
A = -4

So the values of A and B are A = -4 and B = 1.

Step 4: Write the final solution
Now that we have the general solution to the homogeneous equation and the particular solution to the non-homogeneous equation, we can write the final solution as:

Yₙ = A(2ⁿ) + B((-1)ⁿ) + An + B

Substituting the values of A = -4 and B = 1, we get:

Yₙ = -4(2ⁿ) + 1((-1)ⁿ) - 4n + 1

Therefore, the solution to the non-homogeneous difference equation with initial conditions Yₙ₊₂ - Yₙ₊₁ - 2Yₙ = 84n, Y₀ = 1, and Y₁ = -3, is:

Yₙ = -4(2ⁿ) + (-1)ⁿ - 4n + 1.

The vertical stress increment at your location, 13 feet below grade and 9 feet off center of the concentrated load, due to the structural load is approximately 3,282 lb/ft². This information helps in understanding the stress distribution and its impact on the soil and nearby structures.

To calculate the vertical stress increment at your location due to the structural load, we need to consider the weight of the soil, the weight of the water table, and the weight of the concentrated load.

The total vertical stress at your location can be calculated as follows:

p_total = p_soil + p_water + p_load

1. Vertical Stress from Soil:

The vertical stress from the soil is given by the equation:

p_soil = γ_soil * z

Where:

- γ_soil is the unit weight of the soil (128 lb/ft³)

- z is the depth below grade (13 ft)

Substituting the given values:

p_soil = 128 lb/ft³ * 13 ft = 1,664 lb/ft²

2. Vertical Stress from Water:

The vertical stress from the water table can be calculated as follows:

p_water = γ_water * z_water

Where:

- γ_water is the unit weight of water (62.4 lb/ft³)

- z_water is the depth to the water table (6 ft)

Substituting the given values:

p_water = 62.4 lb/ft³ * 6 ft = 374.4 lb/ft²

3. Vertical Stress from Concentrated Load:

The vertical stress from the concentrated load can be calculated as follows:

p_load = P / A

Where:

- P is the concentrated load (460 tons)

- A is the area over which the load is distributed (considering a circular area with a radius of 9 ft)

Converting the concentrated load to pounds:

P = 460 tons * 2,000 lb/ton = 920,000 lb

Calculating the area of the circular load:

A = π * r²

A = 3.14 * (9 ft)² = 254.34 ft²

Substituting the values:

p_load = 920,000 lb / 254.34 ft² ≈ 3,618.39 lb/ft²

Therefore, the vertical stress increment at your location due to the structural load is approximately:

p = p_total - p_soil - p_water

p = 3,618.39 lb/ft² - 1,664 lb/ft² - 374.4 lb/ft²

p ≈ 3,282 lb/ft²

Answer:
If y varies directly as x, then we can write the relationship between y and x as y = kx, where k is a constant of proportionality. To find the value of k, we can use the information given in the problem.

We know that when y is 180 and x is n, we have:

180 = kn

Similarly, when y is n and x is 5, we have:

n = k(5)

To solve for k, we can divide the first equation by the second:

180/n = k(5)/n

Simplifying this expression, we get:

36 = k

Now that we know the value of k, we can use either of the two equations we wrote earlier to solve for n. Let's use the second equation:

n = k(5) = 36(5) = 180

Therefore, the value of n is 180.

Applying the N-A-S rule to [tex]H_3ASO_4,[/tex] we have N = Neutralization, A = Acid (H3ASO4), and S = Salt (depending on the counterions).

To apply the N-A-S (Neutralization-Acid-Base-Salt) rule for [tex]H_3ASO_4,[/tex] let's break down the compound into its ions and analyze the reaction it undergoes in aqueous solution.

[tex]H_3ASO_4[/tex] dissociates into three hydrogen ions (H+) and one arsenate ion [tex](AsO_4^3-).[/tex]

In water, it can be represented as:

[tex]H_3ASO_4(aq) - > 3H+(aq) + AsO_4^3-(aq)[/tex]

Now, let's analyze the N-A-S components:

Neutralization: The compound [tex]H_3ASO_4[/tex] is an acid, and when it dissolves in water, it releases hydrogen ions (H+).

Therefore, N represents the neutralization process.

Acid: [tex]H_3ASO_4[/tex] acts as an acid by donating protons (H+) when dissolved in water.

Hence, A represents the acid.

Base: To identify the base, we look for a compound that reacts with the acid to form a salt.

In this case, water [tex](H_2O)[/tex] can act as a base and accepts the donated protons (H+) from the acid, resulting in the formation of hydronium ions (H3O+).

However, it is important to note that water is often considered a neutral compound rather than a base in the N-A-S rule.

Salt: The salt formed as a result of the neutralization reaction between the acid and base is not explicitly mentioned.

It would depend on the counterions present in the system.

The equation of motion for this scenario is: dv/dt = (515.2 * x - 2.5 * v - 257.6) / 0.248.

To determine the equation of motion for this scenario, we need to consider the forces acting on the system. The weight exerts a gravitational force of 8 pounds, which can be converted to 8 * 32.2 = 257.6 lb*ft/s^2. The spring force opposes the weight and is given by Hooke's Law, which states that the force exerted by a spring is proportional to the displacement from its equilibrium position. The equation for the spring force is F_spring = k * x, where k is the spring constant and x is the displacement.

Since the weight stretches the spring by 0.5 feet, we can substitute the given values into the equation: 257.6 = k * 0.5. Solving for k, we find k = 515.2 lb/ft.

Next, we can consider the damping force. The damping force is given by F_damping = -2.5 * v, where v is the velocity. The negative sign indicates that the damping force opposes the velocity.

Now we can write the equation of motion: m * a = F_spring + F_damping + F_gravity, where m is the mass and a is the acceleration.

The mass is not given, but we can solve for it using the weight: 8 lb = m * 32.2 ft/s^2. Solving for m, we find m = 8 / 32.2 = 0.248 lb*s^2/ft.

With all the values known, we can write the equation of motion as: 0.248 * dv/dt = 515.2 * x - 2.5 * v - 257.6.

Simplifying the equation further, we have: dv/dt = (515.2 * x - 2.5 * v - 257.6) / 0.248.

The COP for Rankine refrigeration cycle is 1.146

The COP for Vapor compression refrigeration cycle is 2.685

The Coefficient of Performance (COP) is a unit of efficiency that measures how effectively a refrigeration cycle or a heat pump can move heat. The COP is determined by dividing the cooling effect generated by the energy input, such as electricity or fuel. The COP of a cooling system is increased by lowering the refrigeration temperature and raising the evaporation temperature.

Calculation of COP for Rankine refrigeration cycle:

Here we use the Rankine cycle as a refrigeration cycle, so we have to consider the following data:

TH = 20 °C = 293 K;

TC = -40 °C = 233 K;

For the calculation of COP, we need to calculate the refrigeration effect. This is calculated as follows:

Refrigeration effect = h1 - h4

where h1 = enthalpy of the refrigerant leaving the evaporator; h4 = enthalpy of the refrigerant entering the compressor.

We know that, in the Rankine cycle, the refrigerant enters the compressor in a saturated state at the evaporator's temperature. Therefore, we have:

h4 = h1 = hf (at -40°C)

Using a steam table, the enthalpy at -40°C, hf, is found to be 71.325 kJ/kg.

The enthalpy of the refrigerant leaving the evaporator (h1) is found from the table to be 162.6 kJ/kg. Therefore,

Refrigeration effect = h1 - h4 = 162.6 - 71.325 = 91.275 kJ/kg

The work input to the compressor is calculated as the difference between the enthalpy of the refrigerant leaving the compressor and the enthalpy of the refrigerant entering the compressor. We have:

h2 - h1

where h2 = enthalpy of the refrigerant leaving the compressor

From the steam table, the enthalpy at 20°C, h1, is found to be 162.6 kJ/kg, and the enthalpy at 20°C and 5 MPa, h2, is found to be 242.2 kJ/kg.

Therefore,

Work input to the compressor = h2 - h1 = 242.2 - 162.6 = 79.6 kJ/kg

The COP of the Rankine cycle is given by:

COP_R = Refrigeration effect / Work input to the compressor

= 91.275 / 79.6

= 1.146

Calculation of COP for Vapor compression refrigeration cycle:

We use the vapor compression refrigeration cycle as a refrigeration cycle here, so we have to consider the following data:

TH = 20°C = 293 K;

TC = -40°C = 233 K;

For the calculation of COP, we need to calculate the refrigeration effect. This is calculated as follows:

Refrigeration effect = h1 - h4

where h1 = enthalpy of the refrigerant leaving the evaporator; h4 = enthalpy of the refrigerant entering the compressor.

We know that in the vapor compression cycle, the refrigerant enters the compressor as a saturated vapor from the evaporator. Therefore, we have:

h4 = hf (at -40°C)

where hf = enthalpy of refrigerant at saturated liquid state at evaporator temperature.

The enthalpy at -40°C is found to be 71.325 kJ/kg from the steam table.

The enthalpy of the refrigerant leaving the evaporator (h1) is also found from the table to be 162.6 kJ/kg. Therefore,

Refrigeration effect = h1 - h4 = 162.

6 - 71.325 = 91.275 kJ/kg

The work input to the compressor is calculated as the difference between the enthalpy of the refrigerant leaving the compressor and the enthalpy of the refrigerant entering the compressor. We have:

h2 - h1

where h2 = enthalpy of the refrigerant leaving the compressor

From the steam table, the enthalpy at 20°C, h1, is found to be 162.6 kJ/kg, and the enthalpy at 20°C and 0.8 MPa, h2, is found to be 196.6 kJ/kg.

Therefore,

Work input to the compressor = h2 - h1 = 196.6 - 162.6 = 34 kJ/kg

The COP of the vapor compression cycle is given by:

COP_VC = Refrigeration effect / Work input to the compressor

= 91.275 / 34

= 2.685

The COP for Rankine refrigeration cycle is 1.146

The COP for Vapor compression refrigeration cycle is 2.685

Hence, the COP for Vapor compression refrigeration cycle is higher than the COP for Rankine refrigeration cycle.

To find the curve of best fit of the type y = ae^bx to the given data using the method of least squares, we need to minimize the sum of the squared differences between the actual y-values and the predicted y-values based on the given equation.

Let's break down the steps:

1. Write down the given data: (10.5,0.12), (39,8.85), (0.12,9.48), and (0.155,7.23).

2. Take the natural logarithm of both sides of the equation to linearize it:
  ln(y) = ln(a) + bx.

  This transforms the equation into a linear form: Y = A + BX, where Y = ln(y), A = ln(a), and B = b.

3. Calculate the values of Y by taking the natural logarithm of the y-values in the data set.

  For example, ln(0.12) ≈ -2.12, ln(8.85) ≈ 2.18, ln(9.48) ≈ 2.25, and ln(7.23) ≈ 1.98.

  So the transformed data set becomes: (-2.12, 0.12), (3.66, 8.85), (2.18, 9.48), and (1.98, 7.23).

4. Calculate the values of X by using the x-values from the given data set.

  The transformed data set becomes: (-2.12, 10.5), (3.66, 39), (2.18, 0.12), and (1.98, 0.155).

5. Now, we can apply the method of least squares to find the best-fit line of the form Y = A + BX.

  Calculate the following sums:
  - Sum of X: ΣX ≈ -1.3
  - Sum of Y: ΣY ≈ 9.74
  - Sum of XY: ΣXY ≈ -8.2
  - Sum of X^2: ΣX^2 ≈ 7.3524

  Calculate the following values:
  - Mean of X: X ≈ -0.33
  - Mean of Y: Y ≈ 2.435
  - Slope of the line: B ≈ -1.118
  - Intercept of the line: A ≈ 3.338

6. Now that we have the values of A and B, we can substitute them back into the original equation to find a and b.

  a = e^A ≈ e^3.338 ≈ 28.2
  b = B

  Therefore, the curve of best fit of the type y = ae^bx for the given data is approximately y = 28.2e^(-1.118x).

- When your car's speedometer reads 45 mph with the 4.65-inch tires, your tires rotate approximately 4.525 times per second.
- When you have the new 5.35-inch tires and your speedometer reads 45 mph, your car is actually traveling at approximately 3.93 rotations per second.
- When you have the new 3.75-inch tires and your speedometer reads 45 mph, your car is actually traveling at approximately 5.614 rotations per second.

Step 1: Convert the tire size to radius
To find the radius of the tire, we divide the diameter by 2. So the radius of the 4.65-inch tire is 2.325 inches.

Step 2: Find the circumference of the tire
The circumference of a circle is calculated using the formula C = 2πr, where C is the circumference and r is the radius. Plugging in the radius, we get C = 2π(2.325) = 14.579 inches.

Step 3: Calculate the number of rotations per second
To find the number of rotations per second, we need to know the linear velocity of the car. We are given that the car is traveling at 45 mph.

To convert this to inches per second, we multiply 45 mph by 5280 (the number of feet in a mile), and then divide by 60 (the number of minutes in an hour) and 60 again (the number of seconds in a minute). This gives us a linear velocity of 66 feet per second.

Next, we need to calculate the number of rotations per second. Since the circumference of the tire is 14.579 inches, for every rotation of the tire, the car moves forward by 14.579 inches. Therefore, to find the number of rotations per second, we divide the linear velocity (66 inches/second) by the circumference of the tire (14.579 inches). This gives us approximately 4.525 rotations per second.

So, when your car's speedometer reads 45 mph, the tires should rotate approximately 4.525 times per second.

Now, let's consider the scenario where you buy new 5.35-inch tires and drive with your speedometer reading 45 mph.

Step 4: Calculate the new linear velocity
Following the same steps as before, we find that the new tire has a radius of 2.675 inches (half of 5.35 inches). The circumference of the new tire is approximately 16.795 inches.

Using the linear velocity of 45 mph (66 inches/second), we divide by the new circumference of the tire (16.795 inches) to find the number of rotations per second. This gives us approximately 3.93 rotations per second.

Therefore, when you have the new 5.35-inch tires and your speedometer reads 45 mph, your car is actually traveling at approximately 3.93 rotations per second.

Lastly, let's consider the scenario where you replace your tires with 3.75-inch tires and your speedometer reads 45 mph.

Step 5: Calculate the new linear velocity
Again, using the same steps as before, we find that the new tire has a radius of 1.875 inches (half of 3.75 inches). The circumference of the new tire is approximately 11.781 inches.

Dividing the linear velocity of 45 mph (66 inches/second) by the new circumference of the tire (11.781 inches), we find that the number of rotations per second is approximately 5.614 rotations per second.

Therefore, when you have the new 3.75-inch tires and your speedometer reads 45 mph, your car is actually traveling at approximately 5.614 rotations per second.

In the x direction, the force is 70 kips (compression), the length is 4 inches, and the area can be calculated as the product of the lengths in the y and z directions, which is 2 inches * 3 inches = 6 square inches.

Deformation in x direction = (70 kips * 4 inches) / (6 square inches * 29 x 10^6 psi)
Deformation in x direction = 0.3238 inches

Now, we can find the single resultant load in the z direction that would produce the same deformation in the x direction.

Using Hooke's Law, we can rearrange the formula to solve for the force:

Force = (Deformation * Area * Modulus of Elasticity) / Length

Substituting the known values:

Force in z direction = (0.3238 inches * 6 square inches * 29 x 10^6 psi) / 3 inches
Force in z direction = 62.78 kips
Therefore, the single resultant load in the z direction that would produce the same deformation in the x direction as the original loadings is 62.78 kips.

For part (b), to determine the single resultant load in the y direction that would produce the same deformation in the z direction as the original loadings, we can follow a similar approach.

First, let's find the deformation in the z direction caused by the original loadings. The deformation can be calculated using the formula:

Deformation = (Force * Length) / (Area * Modulus of Elasticity)

In the z direction, the force is 48 kips (tension), the length is 3 inches, and the area can be calculated as the product of the lengths in the x and y directions, which is 4 inches * 2 inches = 8 square inches.

Deformation in z direction = (48 kips * 3 inches) / (8 square inches * 29 x 10^6 psi)
Deformation in z direction = 0.0582 inches

Now, we can find the single resultant load in the y direction that would produce the same deformation in the z direction.

Using Hooke's Law, we can rearrange the formula to solve for the force: Force = (Deformation * Area * Modulus of Elasticity) / Length

Substituting the known values:

Force in y direction = (0.0582 inches * 8 square inches * 29 x 10^6 psi) / 2 inches
Force in y direction = 63.597 kips
Therefore, the single resultant load in the y direction that would produce the same deformation in the z direction as the original loadings is 63.597 kips.

For part (c), to determine the single resultant load in the x direction that would produce the same deformation in the y direction as the original loadings, we can use the same approach.
First, let's find the deformation in the y direction caused by the original loadings. The deformation can be calculated using the formula:

Deformation = (Force * Length) / (Area * Modulus of Elasticity)
In the y direction, the force is 55 kips (tension), the length is 2 inches, and the area can be calculated as the product of the lengths in the x and z directions, which is 4 inches * 3 inches = 12 square inches.

Deformation in y direction = (55 kips * 2 inches) / (12 square inches * 29 x 10^6 psi)
Deformation in y direction = 0.0262 inches

Now, we can find the single resultant load in the x direction that would produce the same deformation in the y direction.

Using Hooke's Law, we can rearrange the formula to solve for the force: Force = (Deformation * Area * Modulus of Elasticity) / Length

Substituting the known values:
Force in x direction = (0.0262 inches * 12 square inches * 29 x 10^6 psi) / 4 inches
Force in x direction = 62.237 kips

Therefore, the single resultant load in the x direction that would produce the same deformation in the y direction as the original loadings is 62.237 kips.

pH = -log[H⁺] = -log[2.82 x 10⁻⁵] = 4.55. When it is added to a buffer of 0.26 M of NaCH COO, the pH of the solution is 4.55.

1. The pH of the solution with a concentration of 3.1 x 10² M of CH COOH if Ka = 1.8 x 10⁻⁵ is given by:

Ka = [H⁺] [CH COO⁻] / [CH COOH]1.8 x 10⁻⁵ = [H⁺] [CH COO⁻] / [3.1 x 10²]

Hence, [H⁺] = 5.96 x 10⁻⁴M

So, pH = -log[H⁺]

= -log[5.96 x 10⁻⁴]

= 3.23

The pH of the solution with a concentration of 3.1x10²M of CH COOH if Ka = 1.8 x 10⁻⁵ is 3.23.2.

CH COOH + NaCH COO ⇌ CH COO⁻ + Na⁺ + H⁺

The initial concentrations of the reactants are:

[CH COOH] = 3.1 x 10² M[NaCH COO] = 0.26 M

At equilibrium, let the concentration of [H⁺] be x M, then the concentrations of CH COOH, CH COO⁻ and Na⁺ are:

(3.1 x 10² - x) M, (0.26 + x) M and 0.26 M, respectively.

So, applying the equilibrium equation, we get:

Ka = [H⁺] [CH COO⁻] / [CH COOH]1.8 x 10⁻⁵ = x (0.26 + x) / [3.1 x 10² - x]

Now, 3.1 x 10² >> x, so we can approximate the denominator as 3.1 x 10².

Therefore, we have:1.8 x 10⁻⁵ = x (0.26 + x) / [3.1 x 10²]

Solving the above equation, we get:x = 2.82 x 10⁻⁵ M (approx.)

So, pH = -log[H⁺] = -log[2.82 x 10⁻⁵] = 4.55

When it is added to a buffer of 0.26 M of NaCH COO, the pH of the solution is 4.55.

The frictional losses in the suction and discharge lines are determined using the Darcy-Weisbach equation and assuming a friction factor. The elevation difference is considered as the static head difference.

The work done by the pump (Ws) is determined through the mechanical energy balance equation. The equation takes into account the pressure at the pump suction, the density of water, the velocity head, and the elevation difference. The calculated value of Ws is -186.9 J/kg. Assumptions made in the calculations include the friction factor and neglecting minor losses.

Finally, to determine the pump power, we need to know the flow rate. If the flow rate is not provided, we cannot calculate the pump power. However, if the flow rate is known, and assuming an efficiency of 80%, we can calculate the pump power using the equation Power = (Ws * [tex]m_dot[/tex]) / efficiency, where [tex]m_dot[/tex]is the mass flow rate of water.

b) The mechanical energy balance equation for the pump can be written as:

[tex]Ws = ΔH + Ef + Ep[/tex]

where Ws is the work done by the pump per unit mass, ΔH is the change in elevation head, Ef is the frictional losses, and Ep is the pressure head.

To find the coordinate vector of p(t) relative to the basis B, we need to express p(t) as a linear combination of the basis vectors and find the coefficients.

We start by writing p(t) as a linear combination of the basis vectors:

p(t) = c1(1 + t^2) + c2(-2t - t^2) + c3(1 + t + t^2)

Expanding and collecting like terms, we have:

p(t) = (c1 - c2 + c3) + (c1 - 2c2 + c3)t + (c1 - c2 + c3)t^2

Comparing the coefficients of the polynomial terms on both sides, we get the following system of equations:

c1 - c2 + c3 = -5

c1 - 2c2 + c3 = -7

c1 - c2 + c3 = -8

Simplifying the system, we can see that the third equation is redundant as it is the same as the first equation. Thus, we have:

c1 - c2 + c3 = -5

c1 - 2c2 + c3 = -7

Given:

Ka(HC7H5O2) = 6.5 × 10⁻⁵

Concentration of benzoic acid (HC7H5O2) = 0.14 M

Using the formula for percent ionization:

Percent Ionization = [HA]α / [HA] × 100

Where [HA]α is the concentration of ionized benzoic acid (C6H5COO⁻) and [HA] is the initial concentration of benzoic acid (HC7H5O2).

(b) The utilization for the furnace repair team is 67% (4 furnaces serviced / 6 furnaces design capacity). The efficiency is 80% (4 furnaces serviced / 5 furnaces effective capacity).

2. (a) The break-even quantity for the pen producer is 30,000 pens (Fixed costs / Contribution margin per pen: $36,000 / ($2.2 - $1.60)).

(b) The profit for producing 65,000 pens at a selling price of $2.4 each is $16,000 (Profit = Revenue - Total Costs: ($2.4 x 65,000) - ($36,000 + ($1.60 x 65,000))).

In the first situation, the loan operation has a design capacity of 20 loans per day, but it only processes an average of 12 loans per day. This results in a utilization rate of 60%, indicating that the operation is operating at 60% of its maximum capacity. The efficiency is calculated by comparing the average number of loans processed (12) to the effective capacity of the operation (16), resulting in an efficiency rate of 75%. This means that the loan operation is able to utilize 75% of its effective capacity on average.

In the second situation, the furnace repair team has a design capacity of six furnaces per day, but it services an average of four furnaces per day. The utilization rate is calculated by dividing the average number of furnaces serviced (4) by the design capacity (6), resulting in a utilization rate of 67%. This indicates that the furnace repair team is operating at 67% of its maximum capacity. The efficiency rate is determined by comparing the average number of furnaces serviced (4) to the effective capacity of the team (5), resulting in an efficiency rate of 80%. This means that the furnace repair team is able to utilize 80% of its effective capacity on average.

In the third situation, the pen producer has fixed costs of $36,000 per month, which are allocated to the operation, and variable costs of $1.60 per pen. To find the break-even quantity, we need to determine the number of pens that need to be sold in order to cover the total costs. By dividing the fixed costs ($36,000) by the contribution margin per pen ($2.2 - $1.60 = $0.60), we find that the break-even quantity is 30,000 pens. This means that the pen producer needs to sell at least 30,000 pens to cover all the costs and reach the break-even point.

Lastly, if the pen producer produces 65,000 pens and sells them at $2.4 each, we can calculate the profit or loss. The revenue is calculated by multiplying the selling price per pen ($2.4) by the number of pens produced (65,000), resulting in a total revenue of $156,000. The total costs are the sum of the fixed costs ($36,000) and the variable costs ($1.60 x 65,000 = $104,000), amounting to $140,000. Subtracting the total costs from the revenue, we find that the company would make a profit of $16,000.

Hot air is cooled by the air conditioner through a heat exchanger.

The primary function of an air conditioner is to remove heat from the indoor environment and cool it down. The cooling process involves several components, including a heat exchanger.

The heat exchanger in an air conditioner consists of two main parts: the evaporator coil and the condenser coil. The evaporator coil is located inside the indoor unit, while the condenser coil is situated in the outdoor unit. These coils are made of metal and have a large surface area to enhance heat transfer.

When the air conditioner is in cooling mode, the hot indoor air is drawn into the unit through a vent. The air passes over the evaporator coil, which contains a cold refrigerant. The refrigerant absorbs the heat from the air, causing the air to cool down. As a result, the refrigerant evaporates, changing from a liquid state to a gaseous state.

Simultaneously, the gaseous refrigerant is pumped to the outdoor unit, where the condenser coil is located. Here, the refrigerant releases the heat it absorbed from the indoor air. The heat is transferred to the outside environment, typically through a fan or an exhaust system. As the refrigerant loses heat, it condenses back into a liquid state.

The heat exchange process continues cyclically, with the air conditioner removing heat from the indoor air and expelling it outside. This continuous cycle helps maintain a cool and comfortable indoor environment.

In conclusion, the hot air is cooled by the air conditioner through a heat exchanger, specifically the evaporator and condenser coils. The heat exchanger facilitates the transfer of heat from the indoor air to the refrigerant, and then from the refrigerant to the outdoor environment.
