MCQ

The function DD models the population density, in hares per square kilometer, of snowshoe hares in a forest tt years after 1950.

D(t)=2,000cos(2π10t)+2,060D(t)=2,000 \cos (\frac{2 \pi}{10} t)+2,060

What does the solution set for y=2,000cos(0)+2,060y=2,000 \cos (0)+2,060 represent?

Select all that apply :

The maximum population density of hares

The minimum population density of hares

The set of all years in which population density reaches 0 hares per square kilometer.

The first year in which the population density reaches 0 hares per square kilometer.
