Hint for question 6: For this problem you need to use the e" key in your calculator. That key is used for the Natural Exponential Function. You need to evaluate m(t). The function usually looks like m(t) multiplying the constant -k by the number of years given, then press the e" key to raise e to that exponent. Then multiply that number by the value of a, to get the final answer for grams of the radioactive material left. = a· e-k ·t . Do the exponent first by Certain radioactive material decays in such a way that the mass remaining after t years is given by the function m(t) = 455e where m(t) is measured in gráms. 0.025t (a) Find the mass at time t = 0. Your answer is (b) How much of the mass remains after 20 years? Your answer is Round answers to 1 decimal place. Question Help: DVideo Submit Question
