Apopulation of 240 animals decreases at an annual rate of 10%. find the multiplier for the rate of exponential decay. a. 1.9. b. 0.9. c. 0.1. d. 1.1.

. b. 0.9

Step-by-step explanation:

The general exponential decay function is given by :-

, 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 :-

Given: the rate of decay = 10 % = 0.1

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

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

x= 149. 24+7=31. 180-31=149
