1. (a) The amount of U-238 in a sample decays exponentially. Every 2 billion years, 27% of the sample remains. If U(t) is the percentage of the sample remaining after t billion years, find a formula for U(t)? (If you are unable to do part (a), you may use the function U(t) = 80e /3 for the remaining parts). (b) Find the relative growth rate r, the constant growth factor b, and continuous growth rate k.
