A sample of a radioactive substance has an initial mass of 761.7 mg. This substance follows a continuous exponential decay model and has a half-life of 9 days. (a) Lett be the time (in days) since the start of the experiment, and let y be the amount of the substance at time 1. Write a formula relating y to 1. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. = D.D. (b) How much will be present in 5 days? Do not round any intermediate computations, and round your answer to the nearest tenth. mg X DinO S Cubmit Assignm
