Español A certain substance decomposes according to a continuous exponential decay model. To begin an experiment, the initial amount of the substance is 4300 kg. After 8 hours, 3053 kg of the substance is left. (a) Let t be the time (in hours) since the beginning of the experiment, and let y be the amount of the substance (in kg) at time t. Olno Write a formula relating y to 1. Use exact expressions to fill in the missing parts of the formula. Do not use approximations. An y = (b) How much of the substance is left 11 hours after the beginning of the experiment? Do not round any intermediate computations, and round your answer to the nearest whole number.
