I think what your asking for is that x=10

Here we go ~
In the above question, it is given that :

A.) Find f(2) :


or

B.) Find
:

so, we can write it as :



Now, put x =
, and y = x and we will get our required inverse function ~

C.) Find
:



Answer:
Option D.
Step-by-step explanation:
In this problem
we have
where
B is the Final Investment Value or a Balance
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
in this problem we have
substitute in the formula above
SA = 2 * pi * r^2 + 2 * pi * r * h
r = 1
h = 4
pi = 3.14
now sub
SA = 2(3.14)(1^2) + 2(3.14)(1)(4)
SA = 6.28(1) + 6.28(4)
SA = 6.28 + 25.12
SA = 31.4 sq ft
