(10 points) If a constant number h of fish are harvested from a fishery per unit time, then a model for the population P(t) of the fishery at time t is given by = P (a-bP) _ h, P(0) = Po, where a, b, h and Po are positive constants. Since the DE is autonomous, use the phase portrait concept...

4. The population P(t) of a fishery at time t can be given by: = P(5 - P) - 6.25, P(0) = Po. (a) What is the equilibrium solution, i.e. P when = 0? (b) Create a phase portrait and sketch representative curves. (C) Based on the phase portrait, for what values of P, will the population go extinct, i.e. reach 0 in finite time?

8. A fishery is afflicted by a bacterium at t = 0 that prevents the fish from reproducing. It is found that, subsequent to the infection, the per capita death rate in the fishery can be modeled by 8(t) = k. P(t) where k is a constant and P(t) is the population of fish in the fishery at time t > 0. If there are 1000 fish at at t = 0, which IVP will P(t) obey? A. P =...

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...

x'=r (1 - 2 / 2 x where r and K are positive constants, is called the logistic equation. It is used in a number of scientific disciplines, but primarily (and historically) in population dynamics where z(t) is the size (numbers or density) of individuals in a biological population. For application to population dynamics ä(t) cannot be negative. If the solution (t) vanishes at some time, then we interpret this biologically as population extinction. (a) Draw the phase line portrait...

PLEASE ANSWER ALL PARTS The mean number of English courses taken in a two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of four English courses with a standard deviation of 0.8. The females took an average of five English courses with a standard deviation of 1.1. Are the means statistically the same? (Use...
