Question

WORTH 20 PTS!!!

Answer 1

For this case we have the following function:
 $A (t) = A0e ^ {(kt)}$
 Where,
 A0: initial population
 K: rate of change
 t: time in years
 Substituting values we have:
 $A (t) = 22000 * e ^ {(- 0.021 * t)}$
 For the year 2015 we have:
 $A (t) = 22000 * e ^ {(- 0.021 * 5)} A (t) = 19807$
 Answer:
 the predicted population in 2015 is:
 19,807
