A patient is given a sample containing 4 mCi of 89Sr Part 1 of 2 (a) If 30% of the Sr remains in the body after 90 days, write a function of the form Q(t) = Q0e-kt to model the amount (t) of radioactivity in the body t days after the initial dose. Round the value of k to five decimal places. Do not round intermediate calculations. Q (t) =
