In the study of population dynamics one of the most famous models for a growing but bounded population is the logistic equation dP = P (a - bP), where a and are positive constants. Although we …

Suppose that a certain population obeys the logistic equation dy/dt = ry (1 − (y/K)). a.If y0 = K/3, find the time τ at which the initial population has doubled.

Suppose the deer population P (t) in a small forest satisfies the logistic equation dP 0.0225P – 0.0003 p². dt Construct a slope field and appropriate solution curve to answer the following questions: If …

Biologists stocked a lake with 500 fish and estimated the carrying capacity (the maximal population for the fish of that species in that lake) to be 9300. The number of fish tripled in the first year. (a) …

Populations that can be modeled by the modified logistic equation dP = P (bP – a) | dt can either trend toward extinction or exhibit unbounded growth in finite time, depending on the initial population size. …

A population grows according to the given logistic equation, where t is measured in weeks. dP/dt = 0.05P − 0.0025P2, P (0) = 8 (a) What is the carrying capacity?

Assume there is a certain population of deer in a forest whose growth is described by the logistic equation. The growth rate for this type of deer is r = 0.56, and the carrying capacity of the forest is …

Given The data of records the length, in inches, of a colored pencil over time The length of the colored pencil will converge to zero as time increases, so cannot use a trigonometric regression. Using a TI …
