1. 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-640+120sin(t) While the population N of its primary prey is given by: N=21 350+1180cos (t) Find the period length and amplitude of each of these populations. For predator equation: the period = 10 and the amplitude equals 640 For prey equation: the period 8 and the amplitude equals 21350 For predator equation: the period = and the amplitude equals 120 10 For prey equation: the period = 8 and the amplitude equals 1180 For predator equation: the period = For prey equation: the period = 4 and the amplitude equals 21350 and the amplitude equals 640 10 For predator equation: the period = 5 and the amplitude equals 120 For prey equation: the period = 4 and the amplitude equals 1180 For predator equation: the period 10 and the amplitude equals 120 For prey equation: the period = 8 and the amplitude equals 1180
