An exponential decay function can be used to model the number of grams of a radioactive material that remain after a period of time. A radioactive isotope decays over time, with the amount remaining after t years given by y = 100e -0.00012434t if 100 grams is the original amount. How much remains after 2000 years? (a) The amount of a radioactive isotope remaining after 2000 years is approximately grams. (Type an integer or decimal rounded to the nearest tenth as needed.)
