Given the function f(x) = 2^x, find the value of f^−1(32).
klio [65]
f(x)= 2^{x}

We are to find the value of f^{-1}(32)

First we need to find the inverse of f(x) . The inverse of 2^{x} is \frac{ln(x)}{ln(2)}.

Steps to find inverse of f(x) are shown below in the image.

So f^{-1}(32) = \frac{ln(32)}{ln(2)}=5

Therefore, the correct answer is option C

A retangular athletic field is twice as long as it is wide. If the perimeter of the athletic field is 180 yards, what are its di
pishuonlain [190]
W= width
l= 2w= length

Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation

180= 2(2w + w)
multiply 2 by parentheses

180= 4w + 2w
combine like terms

180= 6w
divide both sides by 6

30 yards= w


LENGTH
2w= 2(30)= 60 yards

CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180


ANSWER: the width is 30 yards and the length is 60 yards

Hope this helps! :)
