Element X is a radioactive isotope such that its mass decreases by 82% every year. If an experiment starts out with 410 grams of Element X, write a function to represent the mass of the sample after tt years, where the daily rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per day, to the nearest hundredth of a percent.  Include the function and the rate of decay/
