6.8.3-GC Question Help A radioactive material decays according to the function A(t) = An e -0.02441, where An is the initial amount present and A is the amount present at time t (in years). Assume that a scientist has a sample of 800 grams of the radioactive material. (a) What is the decay rate of the radioactive material? (b) Graph the function using a graphing utility. (c) How much radioactive material is left after 40 years? (d) When will only 600 grams of the radioactive material be left? (e) What is the half-life of the radioactive material? (a) The decay rate of the radioactive material is - 2.44 %. (Type an integer or a decimal.) (b) Graph the function. Choose the correct graph below. The graphing window is [0,1600,100] by [0,1,0.25]. D. (c) There will be about gram(s) of the radioactive material left after 40 years. (Do not round until the final answer. Then round to the nearest tenth as needed.) - 0.0244t A radioactive material decays according to the function A(t) = Ao e Assume that a scientist has a sample of 800 grams of the radioactive material.
