Od domain: 0≤x≤182

Answers

For the function in the given case the constraint on domain can be written as  x ≥ 182. The correct option is (a).

What is a function?

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

Suppose the amount of money spent be x.

And, the number of food items be y.

Now, as per the question the function can be written as follows,

y = x/182

As the number of food items can only be positive integers, the values of x must be the multiples of 182.

Thus, the expression for the domain can be written as x ≥ 182.

Hence, the constraint on the domain is given as x ≥ 182.

Answers

The time needed for the account value to reach 11200 dollars is approximately 15.9 years.

What is the time required to reach the accrued amount?

Simple interest formula is expressed as;

A = P( 1 + rt )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given the data in the question;

Accrued amount A = $11200 Principal P = $5400Interest I = 6.75%Time r = ?

Plug the given values into the above formula and solve for time t.

A = P( 1 + rt )

A/P = 1 + rt

( A/P - 1 ) = rt

t = ( A/P - 1 ) / r

t = ( $11200/$5400 - 1 ) / 6.75%

t = ( $11200/$5400 - 1 ) / 6.75/100

t = ( 56/27 - 1 ) / 0.0675

Find m in equation, W=1/2*m*v squared?

Answers

Answer: To find the value of m in the equation W = 1/2 * m * v^2, you need to know the values of W and v. The variable m represents the mass of the object, and W represents the kinetic energy of the object. The equation states that the kinetic energy of an object is equal to 1/2 of its mass multiplied by its velocity squared.

If you are given the values of W and v, you can solve for m by rearranging the equation as follows:

m = 2 * W / v^2

Plugging in the values of W and v will give you the value of m.

For example, if W = 100 joules and v = 10 meters per second, the equation would be:

m = 2 * 100 joules / 10 m/s^2 = 20 kilograms

This is the mass of the object.

Answer:

A rectangle is 5 inches long and 2x inches wide. The value of the perimeter in inches) is equal to the value of the area (in square inches). Find x.

Answers

Answer:

the width of the rectangle is -5/3 inches.

Step-by-step explanation:

To find the perimeter of the rectangle, we add together the lengths of all four sides. Since the rectangle is 5 inches long and 2x inches wide, the perimeter is given by:

Perimeter = 5 + 2x + 5 + 2x = 10 + 4x

To find the area of the rectangle, we multiply the length by the width. The area is given by:

Area = 5 * 2x = 10x

Setting the perimeter equal to the area, we have:

10 + 4x = 10x

Subtracting 10 from both sides, we have:

4x = 10x - 10

Combining like terms, we have:

-6x = -10

Dividing both sides by -6, we have:

x = 10 / -6

Simplifying, we have:

x = -5/3

Answers

We can estimate the number of adult partons at 2187 by solving equations.

What do we mean by equations?

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions.

A function is an equation that has only one answer for y for every possible value of x.

When utilizing a function, each input of a specific type receives exactly one output.

A function is commonly referred to as f(x) or g instead of y. (x).

Because f(2) instructs us to do so, we should figure out the value of our function when x is equal to 2.

So, the total number of adults present was thus:

Let a be an adult, and b and c be kids.

Ticket totals:

a + c = 5200

c = (5200-a)

Total amount:

7.50a + 4.50c = 29961

In the first equation, swap out c with (5200-a).

7.5a + 4.5(5200-a) = 29961

7.5a + 23400 - 4.5a = 29961

7.5a - 4.5a = 29961 - 23400

3a = 6561

a = 6561/3

a = 2187

Therefore, we can estimate the number of adult partons at 2187 by solving equations.

Round to the nearest thousand dollars.

Answers

Hello,

I hope you and your family are doing well!

A) To find the annual growth rate between 1991 and 2008, we can use the compound interest formula:

S = P(1 + r)

Where S is the final value of the house, P is the initial value of the house, and r is the annual growth rate.

Plugging in the values from the problem, we get:

165,000 = 95,000(1 + r)

Dividing both sides of the equation by 95,000 gives:

1.737 = 1 + r

Subtracting 1 from both sides of the equation gives:

0.737 = r

The annual growth rate between 1991 and 2008 is 0.737.

B) To express the growth rate in percentage form, we can multiply it by 100%:

0.737 * 100% = 73.7%

So the annual growth rate between 1991 and 2008 was 73.7%.

C) To find the value of the house in the year 2011, we can use the compound interest formula again, with the initial value of the house set to the final value in 2008:

S = P(1 + r)

Plugging in the values from the problem, we get:

S = 165,000(1 + 0.737)

Solving for S gives:

S = 165,000 * 1.737 = 285,195

So the value of the house in the year 2011 will be approximately $285,195. Rounded to the nearest thousand dollars, this is $285,000

The vertices of a rectangle are W(1, 2) X(4, 2) Y(4, 23) and Z(1, 23) Find the perimeter of the rectangle is 16.

Step-by-step explanation:

We could use the distance formula to find the distance between the points in this problem, but when we look we see that the sides of the rectangle are parallel to the x and y-axis for each pair of sides. The first two points have a distance of 3 because 4-1=3. Since it is a rectangle, the opposite side will have the same length. For the sides perpendicular, we look at the points with the same x coordinate. Using (4,2) and (4,-3), we can calculate the length of the side by finding the distance by adding the absolute values of the y coordinate. 2+3=5. This means that the triangle has two sides with a length of 5 and two sides with a length of 3. Adding these together, 5+5+3+3 = 16.

Step-by-step explanation:

Albert

(a) $1000 at 1.2 % compounded monthly

A = P (1 + r/n )^nt

A = 1000(1 + 0.001)¹²⁰ = $1127.43

(b) $500 losing 2%

0.98 × 500 = $490

(c) $500 compounded continuously at 0.8%

A = Pe^rt

  = 500e^0.008 * 10

 =  $541.64

(d) Balance

Total = 1127.43 + 490.00+ 541.64 = $2159.07

Marie

(a) 1500 at 1.4 % compounded quarterly

A = 1500(1 + 0.0035)⁴⁰ = $1724.99

(b) $500 gaining 4 %

1.04 × 500 = $520.00

(c) Balance

Total = 1724.99 + 520.00 = $2244.99

Hans

$2000 compounded continuously at 0.9 %

A = 2000e^0.009 * 10

  = $ 2188.35

Max

(a) $1000 decreasing exponentially at 0.5 % annually

A = 1000(1 - 0.005)¹⁰= $951.11

(b) $1000 at 1.8 % compounded biannually

A = 1000(1 + 0.009)²⁰ = $1196.29

(c) Balance

Total = 951.11 + 1196.29 = $2147.40

Marie is $10,000 richer at the end of the competition.

Hope this helps!!! :)

The solutions of the given system of Equations are (5/2, 41/2).

What are the Solutions of Equations:

The set of values for each variable in a system of linear equations is referred to as the solution set.

The intersection or meeting points of the lines or planes used to illustrate the linear equations are also known as the solutions.

The elimination method is one way of resolving a system of linear equations. To obtain the equation in one variable using this technique, simply add or subtract the equations.

Here we have

y = 9x-2 --- (1)

y = 7x+3 --- (2)

From (1) and (2)

=>  9x - 2 = 7x + 3

=>  9x - 7x = 3 + 2

=> 2x = 5

=> x = 5/2

Substitute x = 5/2 in (1)  

=> y = 9(5/2) - 2  

=> y = (45/2) - 2

=> y = (45 - 4)/2

=> y = 41/2

Therefore,

The solutions of given system of Equations are (5/2, 41/2).

In a lottery game, a player picks six numbers from 1 to 28. If the player matches all six numbers, they win 50,000 dollars. Otherwise, they lose $1.

What is the expected value of this game?

Answers

The expected value of this game will be 1,784.75.

What is the expected value?

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

In a lottery game, a player picks six numbers from 1 to 28. Assuming the player matches each of the six numbers, they win 50,000 bucks. In any case, they lose $1.

Then the probability of winning (p) and losing (q) is given as,

p = 1 / 28

q = 27 / 28

Then the expected value is given as,

E(x) = 50,000 (1 / 28) - 1 (27 / 28)

E(x) = 1785.714 - 0.964

E(x) = 1,784.75

The expected value of this game will be 1,784.75.
