Answer:

8 $\pi$ miles or 25.133 miles

Step-by-step explanation:

your radius is 4 miles.

The area of a circle is A= $\pi r^{2}$

Therefore, the area of this circle is $4^{2} \pi$ , or 16 $\pi$

Half of this area, because what you're looking for is a semi-circle, is:

8 $\pi$ (exact) or 25.133 (rounded) miles.

If f(x) = 5x-3, which expression represents its inverse function?

valentinak56 [21]

Answer:

Pretty sure it's C

Step-by-step explanation:

For inverse functions, I do the opposite operation

the only logical inverse function I see working in this expression would be C

divide the 5 from 5x and add the 3

Also, subtract the f(x) on both sides to get the "- y"

so, you get : 5/x + 3 = - y (f(x) is just "y")
