Fluorodeoxyglucose is a derivative of glucose that contains the radionuclide fluorine-18 (¹8F). A patient is given a sample of this material containing 270 MBq of 18F (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: 0/2 Part 1 of 2 -kt (a) Write a function of the form Q(t)=Qe to model the radioactivity level (t) 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. 2(t)= 09 X e 5
