A field currently contains 20 mint plants. Absent constraints, the number of plants would increase by 30%
each year, but the field can only support a maximum population of 100 plants. Use the logistic model to
predict the population in the next two years. Round answers to 1 decimal place.
P1 =
P₂ =
An ODE is said to be of order n if the nth derivative of the unknown function y is
the highest derivative of y in the equation.
True
O False
Suppose 30 blackberry plants started growing in a yard. Absent constraint, the blackberry plants will spread by 80% a month. If the yard can only sustain 110 plants, use a logistic growth model to estimate the number of plants after 3 months.
