89 Painful bone metastases are common in advanced prostate cancer. Physicians often order treatment with strontium-89「Sr), a radionuclide with a strong affinity for bone tissue. A patient is given a sample containing 4 mCi of Sr. 89 Part: 0/2 Part 1 of 2 (a) If 30% of the 89Sr remains in the body after 80 days, write a function of the form Q (t-Qoe-kit model the amount () 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. 00-
