For a certain drug, the rate of reaction in appropriate units is given by where t is time (in hours) after the drug is administered. Find the total reaction to the drug over the following time periods, From t = 1 tot= 12 From t= 12 to t = 24 The total reaction is (Do not round until the final answer. Then round to three decimal places as needed.) The total reaction is (Do not round until the final answer. Then round to three decimal places as needed.)
