An exponential decay function can be used to model the number of grams of aradioactive material that remain after a period of time. A radioactive isotope decaysover time, with the amount remaining after t years given by y = 100e -0.00012434t if100 grams is the original amount. How much remains after 2000 years?(a) The amount of a radioactive isotope remaining after 2000 years isapproximately grams.(Type an integer or decimal rounded to the nearest tenth as needed.)
