A sample of 800 g of an isotope decays to another isotope according to the function A(t) = 800 e-0.032, where t is the time in years. (a) How much of the initial sample will be left in the sample after 20 years? (b) How long will it take the initial sample to decay to half of its original amount? (a) After 20 years, about g of the sample will be left. (Round to the nearest hundredth as needed.) (b) After about \years, the initial sample will decay to half of its original amount. (Round to the nearest hundredth as needed.)
