23x+250 and that would equal your total cost

The intervals on f(x) is increasing on (-∞, 0) and (8/3, ∞), and decreasing on (0, 8/3).

The intervals on which the function f(x) = x³ − 4x² + 10 is increasing or decreasing need to find its derivative and determine its sign.

f(x) = x³ − 4x² + 10

f'(x) = 3x² − 8x

The critical points we set f'(x) = 0 and solve for x:

3x² − 8x = 0

x(3x − 8) = 0

x = 0 or x = 8/3

These are the critical points of the function.

Now we can determine the sign of f'(x) in each interval:

Interval (-∞, 0):

Choose x = -1. f'(-1)

= 3(-1)² - 8(-1)

= 11 is positive.

So f(x) is increasing on (-∞, 0).

Interval (0, 8/3):

Choose x = 1. f'(1) = 3(1)² - 8(1)

= -5 is negative.

So f(x) is decreasing on (0, 8/3).

Interval (8/3, ∞):

Choose x = 3. f'(3) = 3(3)² - 8(3)

= 19 is positive.

So f(x) is increasing on (8/3, ∞).

The actual width of the soccer field is 60 yards.

Given, the scale of the drawing is 1 inch : 5 yards.

The width of the soccer field in the drawing is 12 inches.

So, the actual width of the soccer field can be found by multiplying the width in the drawing by the scale factor:

Actual width = Width in drawing x Scale factor

The scale factor is 5 yards per inch, so we can write:

Actual width = 12 inches x 5 yards per inch

Actual width = 60 yards

Therefore, the actual width of the soccer field is 60 yards.

The graph of g(x) will have the same shape as f(x), but every y-coordinate will be increased by 4 units,The graph of h(x) will have the same shape as f(x), but every x-coordinate will be decreased by 1 unit,The graph of k(x) is 20 and every y-coordinate is increased by 10 units and the graph of m(x) is horizontally squeezed.

To describe the graphs of the given functions, let's first analyze the effects of the transformations applied to the original function f(x) = 5 sin(x).

1. g(x) = 5 sin(x) + 4:

The function g(x) is obtained by vertically shifting the graph of f(x) by 4 units upward. This means that the graph of g(x) will have the same shape as f(x), but every y-coordinate will be increased by 4 units.

2. h(x) = 5 sin(x + 1):

The function h(x) is obtained by horizontally shifting the graph of f(x) to the left by 1 unit. This means that the graph of h(x) will have the same shape as f(x), but every x-coordinate will be decreased by 1 unit. The period of the function remains the same.

3. k(x) = 20 sin(x) + 10:

The function k(x) is obtained by vertically stretching the graph of f(x) by a factor of 20 and then shifting it 10 units upward. This means that the amplitude of the graph of k(x) is 20 (compared to the amplitude of 5 in f(x)), and every y-coordinate is increased by 10 units.

4. m(x) = 5 sin(4x - 1):

The function m(x) is obtained by compressing the graph of f(x) horizontally by a factor of 4, reflecting it across the y-axis, and shifting it 1 unit to the right. This means that the period of m(x) is 1/4 of the period of f(x), and the graph is horizontally squeezed. The reflection across the y-axis means that the graph of m(x) will be inverted compared to f(x). The amplitude remains the same.

Remember that the graph of the original function f(x) = 5 sin(x) represents a sine wave with an amplitude of 5 and a period of 2π. Applying the transformations described above will modify the position, scale, and shape of the graph, resulting in the respective graphs for each function g(x), h(x), k(x), and m(x).

The quartiles of rainfall in April for the city are:

The quartiles refers to the e values that split sorted data into four parts each with an equal number of observations

To determine quartiles, we first need to sort the data in ascending order which are:

There are 20 data points, so, median (Q2) will be the average of the 10th and 11th values.

Q2 = (3.25 + 3.63) / 2

Q2 = 3.44.

The measure of the angles is c = 37. 5 degrees

d = 15 + 37.5 = 52. 5 degrees

To determine the value, we need to know what complementary angles are;

Complementary angles are defined as pair of angles whose sum is equal to 90 degrees

From the information given, we have that;

Angle c and d are both complementary angles

Also, the measure of angle d is 15 degrees greater than the measure of angle c

Then, we have;

d = 15 + c

Substitute the values

c + 15 +c = 90

collect like terms

2c = 90 - 15

2c = 75

Divide both sides by the coefficient

c = 37. 5 degrees

Substitute the value for angles d

Answer:

A. Point estimates are used to make inferences about population parameters.

The function pairs that are inverses are:

C) f(x) = 5x - 3 and g(x) = (x + 3)/5

To determine if two functions are inverses, we need to check if applying one function and then the other function will return the original input.

Let's go through each option:

A) f(x) = -2x and g(x) = (1/2)x

To check if they are inverses, we can apply function f(g(x)) and see if it returns x:

f(g(x)) = f((1/2)x) = -2(1/2)x = -x

Since f(g(x)) = -x ≠ x, these functions are not inverses.

B) f(x) = 4x² and g(x) = √x

To check if they are inverses, we can apply function f(g(x)) and see if it returns x:

f(g(x)) = f(√x) = 4(√x)² = 4x

Since f(g(x)) = 4x = x, these functions are not inverses.

C) f(x) = 5x - 3 and g(x) = (x + 3)/5

To check if they are inverses, we can apply function f(g(x)) and see if it returns x:

f(g(x)) = f((x + 3)/5) = 5((x + 3)/5) - 3 = x + 3 - 3 = x

Since f(g(x)) = x, these functions are inverses.

D) f(x) = x² - 16 and g(x) = x - 4

To check if they are inverses, we can apply function f(g(x)) and see if it returns x:

f(g(x)) = f(x - 4) = (x - 4)² - 16 = x² - 8x + 16 - 16 = x² - 8x

Since f(g(x)) = x² - 8x ≠ x, these functions are not inverses.

Based on the analysis above, the function pairs that are inverses are:

C) f(x) = 5x - 3 and g(x) = (x + 3)/5

Answer:

f(x) = x^2 - 5x + 6

f'(x) = 2x - 5

Since the slope of h(x) is 1/3, the slope of the tangent line to f(x) will have slope -3.

2x - 5 = -3

2x = 2, so x = 1
