Calculus: Exponential Growth and Exponential Decay

(b) Certain bacteria cells are being observed in an experiment. The population triples in 1 hour. If at the end of 3 hours, the population is 27,000, how many bacteria cells were present at the start of the experiment? After how many hours, approximately, will the number of cells reach 1 million? (c) The half-life of a radioactive substance refers to the amount of time it will take for the quantity to decay to half as much as it was originally. Substance Q has a half-life of 20 years. If in 2015, 1003 of Q was at hand, how much will be at hand in 2055? How much will be at hand in 2060
