Chapter 3, Problem 45(choose chapter or problem)
Life science: decay rate. A certain radioactive isotope has a decay rate of 7% per day, that is, where A is the amount of the isotope present at time t, in days. [3.4] a) Find a function that satisfies the equation if the amount of the isotope present at is 800 g. b) After 20 days, how much of the 800 g will remain? Round to the nearest gram. c) After how long will half of the original amount remain?
