Unit 6 HW 10 WILBE Question 8 of 10 (1 point) Question Attempt:1 of Unlimited v 3 8. 9. 10 A specific radioactive substance follows a continuous exponential decay model. It has a half-life of 11 hours. At the start of the experiment, 319.4 g is present. (a) Let i be the time (in hours) since the start of the experiment, and let y be the amount of the substance at time t. Oino Write a formula relating y to t. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. y = (b) How much will be present in 18 hours? Do not round any intermediate computations, and round your answer to the nearest tenth. Save For Later Submit Assignme Check II
