Question
A man starts walking north at 3 ft/s from a point P. Five minutes later a woman starts walking south at 4 ft/s from a point 500 ft due east of P. At what rate (in ft/s) are the people moving apart 15 minutes after the woman starts walking? (Round your answer to two decimal places.) A population of a particular yeast cell develops with a constant relative growth rate of 0.4259 per hour. The initial population consists of 3.5 million cells. Find the population size (in millions of cells) after 4 hours. (Round your answer to one decimal place.) P(4) = million cells
