In a predatory/prey model, the population of a predator is modeled by the function y=900cos(2π3x+8000y=900cos(2π3x+800 0

where x is measured in years. After how many years will the population reach 7,100?

Two parallel lines are crossed by a transversal. what is the value of x? x = 40 x = 70 x = 110 x = 130
