Question

GIVING BRAILIEST PLEASEE!! Given an exponential function for compounding interest, A(t) = P(0.82)t, what is the rate of decay?

A. 18%
B. 8%
C. 0.82%
D. 82%

Answer 1

Answer: I believe the answer is A

Explanation: the exponential function for the compound interest is

That is,

r = rate of interest.

On comparing, we get that,

The rate of interest is 0.18 i.e. 18%.

therefore the rate of interest is 18%.
