The half-life of a certain radioactive material is 42 days. An initial amount of the material has a
mass of 49 kg. Write an exponential function that models the decay of this material. Find how
much radioactive material remains after 8 days. Round your answer to the nearest thousandth.
A. y=49(1/2)^42x;0kg
B. y=1/2(1/49)^1/42x;0.238kg
C. y=49(1/2)^1/42x;42.940kg
D. y=2(1/49)^1/42x;0.953kg
