Question:
The population of foxes in a certain region over a 2-year
Last updated: 7/19/2022
The population of foxes in a certain region over a 2-year period is estimated to be P₁(t) = 300 + 60 sin(πt/12) in month t, and the population of rabbits in the same region in month t is given by P₂(t) = 2000 + 300 cos((πt/12) Find the rate of change of the populations when t = 4. (Express a decrease in population as a negative rate of change. Round your answers to one decimal place.)
