Timothy purchased a computer for $1,000. The value of the computer depreciates by 20% every year. This situation represents
The rate of growth or decay, r, is equal to
year.
So the value of the computer each year is
% of the value in the previous
It will take
years for the value of the computer to reach $512.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
