Suppose that f(x)=x+2x−1 is differentiable and has an inverse for x>1 and f(3)=52. Find (f−1)′(52)Suppose that f(x)=x+2x−1 is
Lorico [155]

Answer:

(f^{-1})'(x) = 1/3

Step-by-step explanation:

(f^{-1})'(x) = \frac{1}{f'(f^{-1}(x))}

if f(x) = y, f^{-1}(y) = x, so

f^{-1}(52) = 3 since f(3) = 52

finding f'(3)

f'(x) = 3

f'(3) = 3

(f^{-1})'(x) = 1/f'(x) = 1/3

As a water quality assurance employee for your local Aqua America, Inc., branch, you record a drop in water levels from 28 feet
ioda
So, it went down from 28 to 7, meaning 28 - 7 = 21, 21 feet then.

now, if we take 28 to be the 100%, what is 21 off of it in percentage?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
28&100\\
21&p
\end{array}\implies \cfrac{28}{21}=\cfrac{100}{p}\implies p=\cfrac{21\cdot 100}{28}
