The population of arctic foxes in Yukon can be modelled by the following equation: P = 400 cos(30t - 180) + 1100 Where 't' represents the number of years since 1992. a. b. C. d. c. What was the population of arctic foxes in Yukon in 1992? What are the maximum and minimum number of arctic foxes? Sketch a graph that represents how the population of artic foxes changes over time (since 1992). What will be the population of arctic foxes in 2030? When was the first time the population of arctic foxes reached 1300 (since 1992)?
