(1 point) The radioactive isotope carbon-14 is present in small quantities in all life forms, and it is constantly replenished until the organism dies, after which it decays to stable carbon-12 at a rate proportional to the amount of carbon-14 present, with a half-life of 5577 years. Suppose C(t) is the amount of carbon-14 present at time t. (a) Find the value ofthe constant k in the differential equation C\" 2 k0, where k
