At the beginning of a study, a certain culture of bacteria has a population of 510. The population grows according to a continuous exponential growth model. After 16 days, there are 918 bacteria. (a) Lettbe the time (in days) since the beginning of the study, and let =) In be the number of bacteria at time . Write a formula relating y to r. % & Use exact expressions to fill in the missing parts of the formula. Do not use approximations. (b P How many bacteria are there 23 days after the beginning cf the study? Do not round any intermediate computations, and round your answer to the nearest whole number. bacteria
