At the beginning of a study, a certain culture of bacteria has a population of 40. The population grows according to a continuous exponential growth model. After 7 days, there are 124 bacteria. (a) Let t 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 t. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. y = 0: (b) How many bacteria are there 17 days after the beginning of the study? Do not round any intermediate computations, and round your answer to the nearest whole number. bacteria olo
