The area covered by a certain population of bacteria increases according to a continuous exponential growth model. Suppose that a sample culture has an initial area of 48.7 mm and an observed doubling time of 13 days. (a) Lett be the time (in days) passed, and let y be the area of the sample at time t. Write a formula relating y to t. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. y = (b) What will the area of the sample be in 11 days? Do not round any intermediate computations, and round your answer to the nearest tenth. mm Continue X In S W
