A population of viruses is increasing at a constant relative growth rate in the bloodstream of its host. After three days the population increases from 260 to 1710. (a) Write a model for the virus population after t days. (Round the relative growth rate to four decimal places.) 62981 A(C) 260 e x (b) According to the model, how many viruses will be present after one week? (Round your answer to the nearest whole number) 21360 x viruses (c) At what rate is the virus population increasing after one week? (Round your answer to four decimal places.) 13453 Xviruses per day
