If the population of the animals decreases by 10% every year. This means that the population for the next year is 90% of that in the previous. The multiplier for the rate of exponential decay is therefore 0.90. The answer is letter B.

Answer: . b. 0.9

Step-by-step explanation:

The general exponential decay function is given by :-

\(f(x)=A(1-r)^x\), where A is the initial valuye , r i sthe rate of decay and x is time period.

The multiplicative rate of exponential decay is given by :-

\(b=1-r\)

Given: the rate of decay = 10 % = 0.1

Then , the multiplier for the rate of given exponential decay will be :-

\(1-0.1=0.9\)

Hence, the the multiplier for the rate of given exponential decay=0.9
