He population P (in thousands) of a certain city from 2000 through 2014 can be modeled by P = 120.7ekt,
where t represents the year, with
t = 0
corresponding to 2000. In 2009, the population of the city was about 167,025.
(a) Find the value of k. (Round your answer to four decimal places.)
k =
Is the population increasing or decreasing? Explain.
Because k is negative, the population is increasing.
Because k is positive, the population is increasing.
Because k is negative, the population is decreasing.
Because k is positive, the population is decreasing.
Correct: Your answer is correct.

(b) Use the model to predict the populations of the city (in thousands) in 2020 and 2025. (Round your answers to three decimal places.)
2020 P =
thousand people
2025 P =
thousand people

The populations are reasonable if it continues to increase at the same rate from the year 2020 to 2025.
