it´s a polygon. letter c (decagon) should be right
hope it helps :)
We must find time by using the simple interest formula:
I = P x i x t
I is the interest
P is the total principal
i is the rate of interest per year
t is the total time in years
In this example, when we plug our known values in, our formula looks like this:
t =

t =

t = 4
So time (in years) would be 4 years.
6.4 is the answer that is the answer
The answer appears to be choice 3 because it resembles an exponential function.
But I might be wrong.
Hope this helps :)
