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 18 hours. There were 95.1 mg of the substance present at the beginning of the study. (a) Let i be the time (in hours) since the beginning of the study, and let y be the amount of the substance at time t. OinD 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 16 hours? Do not round any intermediate computations, and round your answer to the nearest tenth. O mg olo
