Answer:

Step-by-step explanation:

let y = f(x) and rearrange making x the subject

y = 8x + 4 ( subtract 4 from both sides )

y - 4 = 8x ( divide both sides by 8 )

$\frac{y-4}{8}$ = x

Change y back into terms of x with x = $f^{-1}$ (x)

$f^{-1}$ (x) = $\frac{x-4}{8}$ → D

Answer:

$B.~f^{-1}(x)=\frac{x-4}{8}$

Step-by-step explanation:

To find the inverse of a function, swap the places of the x and y variables and solve for y again.

$x=8y+4\\x-4=8y\\\frac{x-4}{8}=y$

Answer:

$\pi x^2-8\pi x+16\pi$

Step-by-step explanation:

To find the area of the inner circle, we need to find its radius. Here, we can write the radius as 4 - x. Now, we can use the formula $A=\pi r^2$ :

A = $\pi$ * $(4-x)^2$

We can expand the square:

A = $\pi *(16-8x+x^2)=\pi x^2-8\pi x+16\pi$

Thus, the polynomial is $\pi x^2-8\pi x+16\pi$ .

Hope this helps!

Answer:

20 feet

Step-by-step explanation:

The speed of horse A is

The speed of horse B is

We define the speed as distance divided by time.

Given that the horses started the race at the same time (and assuming in the same position) we can write :

After 5 seconds for Horse A :

After 5 seconds, Horse A will have traveled 160 feet

After 5 seconds for Horse B :

After 5 seconds, Horse B will have traveled 140 feet

The difference between the distances :

is how much farther Horse A will have traveled.

After 5 seconds, The Horse A will have traveled 20 feet farther than the Horse B.
