Exponential and Logarithmic Functions 0/5 Evaluating an exponential function that models a real-world situation V The radioactive substance uranium-240 has a half-life of 14 hours. The amount A (1) of a sample of uranium-240 remaining (in grams) after t hours is given by the following exponential function. 14 A (t) = 1500 Find the initial amount in the sample and the amount remaining after 60 hours. Round your answers to the nearest gram as necessary. Initial amount: [ grams Amount after 60 hours: [ grams K X 5
