Question

The population of a certain inner-city area is estimated to be declining according to the model P(t)=452,000e−0.014t, where t is the number of years from the present. What does this model predict the population will be in 8 years? Round to the nearest person.

Answer 1

404,108

Explanation:

Put 8 where t is and do the arithmetic.

P(8) = 452,000·e^(-0.014·8) ≈ 404,108

The population is predicted to be 404,108 in 8 years.
