Suppose that the amount of a radioactive medical tracer in the bloodstream of a patient is described by r(t) = 389e-0.1 (units omitted). a. What is the average rate of change of the amount of tracer in the bloodstream over the first hour of the trial, that is from to = 0 until tj = 1? avg. r.o.C = b. Write the equation of the secant line that connects the values at to = 0 and t1 = 1 on the graph of r(t) (be mindful of the variable name). sec(t) = 1 c. Find the time that the population reaches a size of s(t) = 224.5. t= 5.49 d. The area under the curve r(t) gives a measure of the amount of radioactivity that the patient has been exposed to over some time. Find So r(t)dt = %. 389e-0.11 dt to quantify the amount of exposure. S. 389e-0.11 dt = 370.18
