Formula is f(x) - ab^x. so we would need to get b. we would have to change the percentage to a decimal. so shift it 2 times to the right. which is 0.015 = b. hope this helps :D
What are you doing this is not understood
I got A, -32, but it has been awhile since I have learned this in my math class. You might want to wait for someone else to verify this answer.
Answer:
A = 400 cm^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
80 = 4s
Divide each side by 4
80/4 = 4s/4
20 =s
We want to find the area of the square
A = s^2
A = 20^2
A = 400 cm^2
