I need help with this question​

Answer 1

See below.

Explanation:

The initial population is when t = 0, so substituting t = 0 into the given formula:

Initial Population = 280 / (1 + 4*e^(-0.45*0))

= 280 / (1 +4)

= 56 animals Answer.

Population after 9 years = 280 / (1 + 4*e^(-0.45*9))

= 262 animals Answer.
