Question

A radioactive material decays according to the function A t Age 0 02451 where Ao is the initial amount present and A is the amount present at time t in years Assume that a scientist has a sample of 400 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 300 grams of the ladioactive material be left e What is the half life of the radioactive material b Graph the function Choose the correct graph below The graphing window is 0 800 100 by 0 1 0 25 O A OD Q B c There will be about 150 1 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 d In about 11 7 year s only 300 grams of the radioactive material will be left Do not round until the final answer Then round to the nearest tenth as needed e The half life of the radioactive material is about year s Do not round until the final answer Then round to the nearest tenth as needed Q
