Problem 9. (10 points) PLEASE SUBMIT HAND WRITTEN SOLUTIONS TO BLACKBOARD A 1500 mg sample of a radioactive isotope has a half-life of 6 days. The mass of the sample after days can.be computed using the function P(t) =1500-2 mg Find a function R(t) to compute the rate of decay of the sample after days. R(f;) =['}| mg/day Compute the number of days it days it takes for the rate of decay to reduce to 500 mg/day. (round to 3 decimal places) = !days Note: You can earn partial credit on this
