A cell of this bacterium in a nutrient-broth medium divides into two cells every 20 minutes. The initial population of a culture is 78 cells. (a) Find the relative growth rate. (Assume t is measured in hours.) k = In(8) (b) Find an expression for the number of cells after t hours. P (t ) = 78( 8' ) (c) Find the number of cells after 8 hours. 1308622848 cells (d) Find the rate of growth after 8 hours. (Round your answer to three decimal places.) 2.721 billion cells per hour (e) When will the population reach 20,000 cells? (Round your answer to two decimal places.) 2.81 x hr Enhanced Feedback Please try again. Remember, if the growth rate of a population, P, is proportional to the population itself, then the growth rate is given by the formula = KP, where k is the relative growth rate. Try finding k when t is measured in hours. The formula for population as a function of time is given by P(t) = Poekt, where Po is the population at time 0. Need Help?
