Investigate the following harvesting model both qualitatively and analytically. 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 dP dt = P(a − bP) − h, P(0) = P0, where a, b, h, and P0 are positive constants. Suppose a = 9, b = 1, and h = 81 4 . Determine whether the population becomes extinct in finite time. The population becomes extinct in finite time for all values of P0. The population becomes extinct in finite time if P0 < 9 2 . The population does not become extinct in finite time. The population becomes extinct in finite time if P0 > 9 2 . The population becomes extinct in finite time if P0 = 9 2 . If so, find that time. (If not, enter NONE.)

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

Gexpressions: practice question 3 of 5 jackson wants to study the popularity of his music video by tracking the number of views the video gets on his website. the expression below represents the total number of views that jackson's video receives n days after he begins tracking the nu views, where b is the rate at which the number of views changes. alb)" select the statement that would accurately describe the effect of tripling a, the initial number of views before jackson beginst the rate at which the number of views changes, b, will triple. the total number of views the video has after n days, a(b)", will not change. the total number of days since jackson begins tracking views, n, will be reduced by one-third. the total number of views the video has after n days, alb)", will triple. submit

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1
