lest Question 8 of 10 (5 points) Question Attempt: 1 of 1 Time Remaining: 1:41:04 5 6 9 = 10 Fluorodeoxyglucose is a derivative of glucose that contains the radionuclide fluorine-18 (" F). A patient is given a sample of this material containing 330 MBq of 18 F (a megabecquerel is a unit of radioactivity). The patient then undergoes a PET scan (positron emission tomography) to detect areas of metabolic activity indicative of cancer. After 174 min, one-third of the original dose remains in the body. Part 1 of 2 (a) Write a function of the form Q (1) - Coe to model the radioactivity level @ () of fluorine-18 at a time t minutes after the intial dose. Round the value of k to five decimal places. Do not round intermediate calculations. e(1) = 330e -0.0063/ e X Part: 1 / 2 Part 2 of 2 (b) What is the half-life of F? Round to the nearest minute. Do not round intermediate calculations. The half-life of F is approximately min. X
