Answer:

Step-by-step explanation:
The initial value of the population is 650
Each year the population increases 160
The population oscillates 19 above and below.
Due to this information you can assume that the function is:

where for t=0 p(t)=650
where t=12 160/12 (12) = 160
you can assume that the sinusoidal function has a period of one month. Thus, the population oscillates several times in one year with an amplitu of the oscillation of 19. The, w is:

Answer:
answer is 3 or 50 degrees
Step-by-step explanation:
