Part B Please!!
Scenario The population of fish in a fishery has a growth rate that is proportional to its size when the population is small. However, the fishery has a fixed capacity and the growth rate will be negative if the population exceeds that capacity. A. Formulate a differential equation for the population of fish described in the scenario, defining all parameters and variables. 1. Explain why the differential equation models both condition in the scenario. t time a...

(1 point) The population of mice in Alfred is given by P(t) = 2102e", where t is in years since 1986. The rate of change of the population is given by the formula mice/yr. In year 1991 the population changes by approximately mice. In 1991 2.38586299264431e+23 mice died, which means that mice were born that year.

Population Growth: Let P(t) be the number of rabbits in the
rabbit population. In the simplest case we can assume the number of
rabbits born at any moment of time is proportional to the number of
rabbits at this moment of time. Mathematically we can write this as
a differential equation:
Here b is the birth rate, i.e. births per time unit per rabbit.
In the model above we ignore deaths and assume resources are
unlimited.
A. Solve the equation...
