Solve the problem.Wildlife management personnel use predator-prey equations to model the populations of certain predators and their prey in the wild. Suppose the population M of a predator after t months is given by M = 750 + 125 sin 
twhile the population N of its primary prey is given by N = 12,250 + 3050 cos 
t.Calculate both M and N for t = 3, t = 15, and t = 27 months. Explain the answers in terms of reference angles. Without calculating them, what will be the values of M and N for t = 39 months?
What will be an ideal response?
For all 3 values of t, M = 875 and N = 12,250; 
is the reference angle for the given values of 
t;
for t = 39, M = 875 and N = 12,250.
