The mass of a substance, which follows a continuous exponential growth model, is being studied in a lab. The doubling time for this substance was observed to be 21 minutes. There were 5.6 mg of the substance present the beginning of the study. (a) Let r be the time (in minutes) since the beginning of the study, and let y be the amount of the substance at time r. Dino Write a formula relating y to t. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. (b) How much will be present in 17 minutes? Do not round any intermediate computations, and round your answer to the nearest tenth. Dlo
