Question 1154523: A radioactive substance decays in such a way that the amount of mass remaining after t days is given by the function
m(t) = 15e−0.012t
where m(t) is measured in kilograms.
(a) Find the mass at time t = 0.
kg
(b) How much of the mass remains after 41 days? (Round your answer to one decimal place.)

---------------------------------
m(t) = 15e−0.012t
should be m%28t%29=15e%5E%28-0.012t%29
where m(t) is measured in kilograms.
(a) Find the mass at time t = 0.
kg
(b) How much of the mass remains after 41 days? (Round your answer to one decimal place.)
