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 1.9 mm" and an observed doubling time of 4 minutes. (a) Let : be the time (in minutes) passed, and let y be the area of the sample at time t. OIno Write a formula relating y to t. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. (b) What will the area of the sample be in 5 minutes? Do not round any intermediate computations, and round your answer to the nearest tenth.
