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
Pythagoras: A^2 + B^2 = C^2 where c is the side opposite the hypotenuse (opposite the right angle) and B and C are the other sides. Trigonometry: SOH CAH TOA where you can use their formula where sin = opposite/ hypotenuse Cos= adjacent/ hypotenuse Tan= opposite/ adjacent
In additive inverse, the sum of two numbers is always 0
