Answer: 19807
Step-by-step explanation:
Given: In Texas, the population of a species of bats is decreasing at a rate of -0.021 per year.
The population was 22,000 in 2010.
The given function :
, where is the initial value and k is the rate of decay.
Consider 2010 as the initial year, then
k=-0.021 per year
For year 2015 , t=2015-2010=5
Hence, the predicted population in 2015 = 19807
