Question
Every year, the population of squirrels in Ireland increases at a constant rate of 200 squirrels/year. At the same time, throughout the year squirrels are leaving Ireland to live in Scotland at a rate of t3 squirrels/year. Let P(t) be the population of the squirrels in Ireland.
Which of the following differential equations could describe this scenario?
Transcribed Image Text:P' (t) = 200 + kt³, where k ‡ 1 is a positive constant.
OP' (t) = 200 +t³
OP' (t) = 200- t³
OP' (t) = 200 - kt³, where k 1 is a positive constant.
