From the calculations, only question 2 shows that f(x) is the inverse of function g(x) as the rest shows the parent functions are not inverse of g(x)

In the given question, we are to determine if the parent function f(x) is an inverse to g(x).

1. f(x) = 2x - 9

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

Let's switch the variables: y = 2x - 9 to x= 2y - 9.

We can proceed to solve the equation as;

x =2y - 9 for y.

y= x + 9 / 2

Therefore, f(x) is not an inverse of g(x)

2. f(x) = x - 3 / 4

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

Let's switch the variables:

y = x / 4 - 3/4 to x = y / 4 - 3/4

we can solve the equation for y to give us;

y = 4x + 3

This shows that f(x) is inverse of g(x)

4. f(x) = 7x^3/2 - 4

To find the inverse function, swap x and y and solve the resulting equation for x

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables:

y = 7x^3/2 - 4 will become x = 7y^3/2 - 4

Solving for y;

y = [(∛7(x + 4))^2/3] / 7

This shows f(x) is not the inverse of g(x)

The surface area of the cylinder is 1851.97 square meters

From the question, we have the following parameters that can be used in our computation:

Radius, r = 13.1 meters

Height, h = 9.4 meters

Using the above as a guide, we have the following:

Surface area = 2πr(r + h)

Substitute the known values in the above equation, so, we have the following representation

Surface area = 2π * 13.1 * (13.1 + 9.4)

Answer:

The perimeter of the entire frame is equal to the sum of the perimeters of the mat and the picture. The expression for the perimeter of the mat is (2m + 10) + (2m + 8) = 4m + 18, and the expression for the perimeter of the picture is 2(8) + 2(10) = 36. Therefore, the expression for the perimeter of the entire frame is (4m + 18) + 36 = 4m + 54.

Answer:

The roots of the quadratic equation x² + 4x + 7 = 0 can be found using the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a

In this case, a = 1, b = 4, and c = 7. Substituting these values into the formula, we get:

x = (-4 ± √(4² - 4(1)(7))) / 2(1)

x = (-4 ± √(16 - 28)) / 2

x = (-4 ± √(-12)) / 2

x = (-4 ± 2i√3) / 2

x = -2 ± i√3

Therefore, the roots of the equation x² + 4x + 7 = 0 are: A) 2 + i√3 or 2 - i√3.

The polynomial function with fifth degree and given zeroes is 4x⁵ - 20x⁴ + 64x³ + 324x² - 432x.

The maximum power of the variable in a polynomial function is its degree. For instance, since 2 is the largest power of x, the polynomial function f(x) = 3x2 + 2x + 1 has a degree of 2. We only take into account the degree of the term with the highest power of x when a polynomial function comprises many terms. A polynomial with no x terms is a constant function, and thus has degree zero.

To determine the polynomial, we determine the zeroes.

Given that, 3 is a zero of multiplicity 3,-4 is the only other zero thus:

(x - 3)³(x + 4)

Now, for leading coefficient 4 we have:

4x(x - 3)³(x + 4)

Thus, solving the parentheses we have:

4x(x³ - 9x² + 27x - 27)(x + 4)

(4x⁴ - 36x³ + 108x² - 108x)(x + 4)

4x⁵ - 36x⁴ + 108x³ - 108x² + 16x⁴ - 144x³ + 432x² - 432x

4x⁵ - 20x⁴ + 64x³ + 324x² - 432x

Hence, the polynomial function with fifth degree and given zeroes is 4x⁵ - 20x⁴ + 64x³ + 324x² - 432x.

Answer:

Let the cost of one apple pie be A and the cost of one blackberry pie be B.

From the first statement, we can write the equation:

SA + 4B = 8140 ----(1)

From the second statement, we can write the equation:

4*B = 152

Solving for B:

B = 38

Substituting B in equation (1) and solving for A:

SA + 438 = 8140

S*A = 8008

A = 8008/S

We do not have enough information to find the value of S or A individually, but we can find the relationship between them:

A/B = (8008/S)/38 = 211/S

Therefore, the cost of one apple pie is 211 times the cost of one blackberry pie.

The value of the angle x is 108 degrees

To determine the value, we need to note that the sum of the angles on a straight line is 180 degrees.

Also, parallel lines are lines that do not meet or intersect each other on any side of a plane

The annual depreciation expense for this car is $1,833.33.

Simply deduct the vehicle's current fair market value from the purchase price, less any applicable sales tax or fees, to determine how much value has been lost.

We must determine the total depreciation throughout the vehicle's useful life and divide it by the number of years to determine the annual depreciation expense:

Total depreciation = purchase price - resale value

= $28,500 - $17,500

= $11,000

Annual depreciation expense = total depreciation / useful life = $11,000 / 6 = $1,833.33 (rounded to the nearest hundredth)

The length of the square is 1.75 inches, while the king's height is 2.25 inches.

Define length.

The length of an object or the extent of a one-dimensional object along its longest dimension is measured physically. It is a basic idea in physics and geometry and is frequently expressed in terms of meters (m), centimetres (cm), feet (ft), or inches (in).

According to the information provided, the square length to king's height ratio is 3.5 to 4.5 inches. Let's use this ratio to determine the square's length when the king is 2.25 inches tall.

We may make a proportion to get the square's length:

(square length) / (king's height) = 3.5/4.5

king's height = 2.25

Let's substitute the given values:

(square length) / 2.25 = 3.5/4.5

To solve for the length of the square, we can cross-multiply:

(square length) = (2.25) x (3.5/4.5)

(square length) = 1.75

Therefore, the length of the square is 1.75 inches, while the king's height is 2.25 inches.

Answer: -13/17

Step-by-step explanation: To find the slope of the line that passes through the points (-9, 7) and (8, -6), you can use the slope formula:

where (x1, y1) = (-9, 7) and (x2, y2) = (8, -6)

Substituting the values in the formula, we get:

slope = (-6 - 7) / (8 - (-9))

slope = -13 / 17
