Español 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 9 days. There were 26.6 mg of the substance present at the beginning of the study. (a) Let i be the time (in days) since the beginning of the study, and let y be the amount of the substance 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. ? (b) How much will be present in 4 days? Do not round any intermediate computations, and round your answer to the nearest tenth. Omg
