Asap! billy is monitoring the exponential decay of a radioactive compound. he has a sample of the compound in a test tube in his lab. according to his calculations, the sample is decaying at a rate of 35% per hour. there are at least 72 grams of the sample remaining. once the sample reaches a mass of 15 grams, billy will continually add more of the compound to keep the sample size at a minimum of 15 grams.
if r represents the actual amount of the sample remaining, in grams, and t represents the time in hours, then which of the following systems of inequalities can be used to determine the possible mass of the radioactive sample over time?
