Roughly 12,000 people in a certain country are diagnosed with thyroid cancer every year, which accounts for 1% of all cancer cases. It occurs in women three times as frequently as in men, Fortunately, thyroid cancer can be treated successfully in many cases with radioactive iodine, or l-131. This unstable form of iodine has a half-life of 8 days and is given in small doses measured in millicuries. -131 in the body after t20 days. a. Suppose a patient is given an initial dose of 100 millicuries. Find the function that gives the amount b. How long does it take for the amount of l-131 to reach 15% of the initial dose? c. Finding the initial dose to give a particular patient is a critical calculation. How does the time to reach 15% of the initial dose change if the initial dose increased by 5%? a. Suppose a patient is given an initial dose of 100 millicuries. Find the function that gives the amount of l-131 in the body after t20 days. y(t) =D (Type an expression. Round coefficients to six decimal places as needed.)
