At the beginning of a study, a certain culture of bacteria has a population of 610. The population grows according to a continuous exponential growth model. After 8 days, there are 915 bacteria. (a) Let r be the time (in days) since the beginning of the study, and let y be the number of bacteria at time t. - Olno Write a formula relating y to r. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. (b) How many bacteria are there 21 days after the beginning of the study? Do not round any intermediate computations, and round your answer to the nearest whole number.
