The population of salmon next year is given by f(S) = Se r(1-s/p) where S is this year's salmon population P is the equibrium population and r is a constant that depends upon how fast the population grows. Find f'(S0) and solve the equation f'(S0) = 1. using a calculator to find the intersection of the graphs f '(S0) and y = 1. Find the population foe which the maximum sustainable harvest occurs if r = 0.4 and P = 850. The maximum sustainable harvest occurs for a population of (Round to the nearest thousandth as needed.) For a certain drug the rate of reaction in appropriate units is given by R'(t) = 4/t + 1 + where t is time (in hours) after the drug is administrated. Find the total reaction to the drug over the following time periods. From t = 1 to t = 13 From t = 13 to t = 24 The total reaction is . (Do not round until the final answer. Then round to three decimal places as needed.)
