Answer:
f(x) = y
y = 7.50x
To find the inverse, swap x and y
x = 7.50y
Now solve for y
y = x/7.50
f-1(x) = x/7.50

Answer:
The value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95
Step-by-step explanation:
Cost of building 20 years ago = 12000000
We are given that the cost depreciated at 9% per year
Formula : 
Where N(t)= Population after t years
=Initial population=12000000
r= rate of depreciation=0.09
t = 20 years
Substitute the values in the formula:

N(t)=1819738.95
Hence the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95
Answer:
x = ±2√10
Step-by-step explanation:
40 - x² = 0
⇌
(√40 - x)(√40 + x) = 0
⇌
x = √40 or x = -√40
we can go further and say that √40 = 2√10
