Answer:

P = 47.1 units

Step-by-step explanation:

the perimeter of the pair of straight opposite sides is 11+11, or 22

now you have 2 semi-circles, which equals 1 full circle which, if we find the circumference to then we just add it to 22 to get the entire answer

Circumference of circle with diameter of 8:

C = 2πr

C = 2π(4)

C = 8π

C = 25.13

now add 22 + 25.13 to get 47.1 rounded to nearest tenths place

The graph of the derivative of a function provides information about the rate of change and the slope of the original function at different points.

To graph the derivative of a function given the graph of the function, you can follow these steps:

Start with the graph of the original function. Make sure you have a clear understanding of its shape and behavior.

Identify critical points on the graph of the function, which are the points where the function has maximum or minimum values or where its slope changes abruptly.

Use the information from the critical points to determine the intervals where the derivative is positive or negative. In the intervals where the function is increasing, the derivative will be positive, and in the intervals where the function is decreasing, the derivative will be negative.

Find any vertical asymptotes or discontinuities in the original function. These points will also affect the behavior of the derivative.

Plot the derivative on a separate graph, using the information from steps 3 and 4. On the derivative graph, mark positive values above the x-axis and negative values below the x-axis.

Indicate the critical points and any vertical asymptotes or discontinuities on the derivative graph.

Connect the points on the derivative graph smoothly, considering the behavior of the original function and the values of the derivative at different points.

By following these steps, you can create a graph of the derivative that provides information about the rate of change and the slope of the original function at different points. The derivative graph helps in understanding the increasing and decreasing behavior of the function and provides insights into its concavity and local extrema.

The value of the composite function f(g(x)) at x = 3 is 25 if the function  f(x) = 2x + 3 and g(x) = 3x + 2 option (C) 25 is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

f(x) = 2x + 3 and

g(x) = 3x + 2

To find the value of f(g(3))

First plug x = 3 in the function g(x)

g(3) = 3(3) + 2

g(3) = 9 + 2

g(3) = 11

Plug the value of g(3) in the function f(x):

f(g(3)) = 2(11) + 3

f(g(3)) = 22 + 3

f(g(3)) = 25

The f(g(x)) is representing a composite function and the value of the composite function at x = 3 is 25.

Thus, the value of the composite function f(g(x)) at x = 3 is 25 if the function  f(x) = 2x + 3 and g(x) = 3x + 2 option (C) 25 is correct.

The function that gives the cost of fencing is given from the graph by the following function;

The reason why the above function is correct is as follows:

Question: Please find attached the required diagram used to obtain the function;

The given parameters are;

Area of the square rectangle = 250 m²

Length of the side of the pen wall parallel to the coop = x

Cost of fencing per foot, c = $10

The function for the cost in dollars of fencing, C(x) = 10x + 5000

Solution:

Let y represent the length of the other side, we have;

x × y = 250

Therefore;

\(P = x + 2 \times \dfrac{250}{x} = x + \dfrac{500}{x}\)

The total cost of the fencing, C(x) = c × P

Therefore;

\(\mathbf{C(x)} = 10 \times \left(x + \dfrac{500}{x} \right) = 10 \cdot x + \dfrac{5,000}{x}\)

The graph and inverse of a function are reflections of each other along the line y = x.

A relation made up of ordered pairs (x, y) has as its inverse the set of all ordered pairs (y, x).

When a point is mirrored over the line y = x, the x- and y-coordinates swap places. Similarly, when a point is mirrored over the line y = -x, the x- and y-coordinates swap places and become negated.

Therefore,

The point (x, y)'s reflection over the line y = x is (y, x).

The point (x, y)'s reflection over the line y = - x is (-y, -x).

Thus, the graph and inverse of a function are reflections of each other along the line y = x.

Answer: The area is 390 cm

Step-by-step explanation:

All you have to do is find the area of the trapezoid and the area of the rectangle and add them together.

Area of trapezoid formula: A = 1/2 (Base 1 + Base 2)h

base 1 = 15 cm

base 2 = 23 cm

height = 6 (18-12)

so, 15 + 23 = 38

38 x 6 = 228

228 x 0.5 or 1/2 = 114

Therefore the area of the trapezoid is 114 cm

Area of rectangle formula: A = bh

base = 23

height = 12

12 x 23 = 276

Therefore the area of the rectangle is 276 cm

Now add the values together, 114 + 276 = 390

390 is the area of the figure

Answer:

$5.05

Step-by-step explanation:

So we know that Esther has to save 65.65 dollars in 13 weeks.

If we want to find out how much money she needs to save up each week then we have to divide 65.65 into 13 weeks ofc.

If we divide 65.65 by 13 we get 5.05 so 5 dollars and 5 cents.

If we check our answer to find out if this is the correct answer we can just multiply 13 by 5.05  and it will of course give you 65.65

So, if Esther wants to save $65.65 in 13 weeks she will have to save up $5.05 each week.

If Mrs hall is making a circular hard for our outdoor green space the garden has a diameter of 11m then Mrs. Hall spent $198.37 on the plastic fencing.

The circumference of a circle can be calculated as C = πd, where d is the diameter and π is approximately 3.14.

The diameter of the garden is 11m, so the circumference is:

C = πd

= 3.14 × 11m

= 34.54m

Mrs. Hall needs to buy enough plastic fencing to go around the edge of the circular garden, which has a length equal to the circumference of the circle.

The cost of the fencing is $5.75 per meter, so the total cost will be:

Total cost = cost per meter × length of fencing

= $5.75/m × 34.54m

= $198.37

Therefore, Mrs. Hall spent $198.37 on the plastic fencing.

Answer:

\(x = 3\)

Step-by-step explanation:

Given equation is ,

3^x - 3^{x-2} = 24

we can write it as,

3^x - (3^x/3^2) = 24

take out 3^x as common,

3^x ( 1 - 1/3^2) = 24

simplify,

3^x (1 -1/9)=24

3^x (9-1/9)=24

3^x * 8/9 = 24

3^x = 24 * 9/8

3^x = 27

3^x = 3^3

on comparing,

x = 3

and we are done!

Answer:

x = 3

Step-by-step explanation:

Given equation:

\(3^x-3^{x-2}=24\)

Rewrite the exponent of the first term as (x - 2 + 2):

\(3^{x-2+2}-3^{x-2}=24\)

\(\textsf{Apply the exponent rule} \quad a^{b+c}=a^b \cdot a^c:\)

\(3^{(x-2)+2}-3^{x-2}=24\)

\(3^{x-2}\cdot 3^2-3^{x-2}=24\)

\(\textsf{Factor out the common term $3^{x-2}$}:\)

\(3^{x-2}(3^2-1)=24\)

Simplify the brackets:

\(3^{x-2}\cdot 8=24\)

Divide both sides by 8:

\(3^{x-2}=3\)

Apply the exponent rule a = a¹ :

\(3^{x-2}=3^1\)

\(\textsf{Apply the exponent rule} \quad a^{f(x)}=a^{g(x)} \implies f(x)=g(x):\)

\(x-2=1\)

Add 2 to both sides of the equation:

\(x=3\)
