Question

In Texas, the population of a species of bats is decreasing at a rate of -0.121 per year. The population was 34,000 in 2000. According to the function, A(t) = A0e(kt) , what is the predicted population in 2015?

Answer 1

Hi there
A (t)=Ae^kt

A (t) ?
A 34000
K -0.121
T time 2015-2000=15 years
E constant

So
A (15)=34,000×e^(−0.121×15)=5,536
