3. Continuous growth or decay follows the formula A(t) = cekt, where c is the initial amount, and k is a rate factor. The initial mass of a radioactive substance is 1000 g, and only 100 g after 100 days. a) Determine the value of k to three decimal places. b) How fast is the sample decaying at 13 days. Round your answer to three decimal places. c) Determine the half-life, round to the nearest whole number.
