Question

3. The population, P, of a lakeside town with a large number of seasonal residents can be modeled using the function P(t)=5000sin(30(t−7))+8000 , where t is the number of months after New Year’s Day.

d) When is the population about 10 000?

Answer 1

5000sin(30(t−7))+8000=10000

5000 Sin(30(t-7))=2000

Sin(30(t-7))=2/5
