# A radioactive substance decays in such a way that the amount of mass remaining after t days is given by the function  m(t) = 13e^-0.011t where m(t) is measured in kilograms. (a) How much of the mass remains after 44 days? (Round your answer to one decimal place.)

Question

A radioactive substance decays in such a way that the amount of mass remaining after t days is given by the function

m(t) = 13e^-0.011t

where m(t) is measured in kilograms.

(a) How much of the mass remains after 44 days? (Round your answer to one decimal place.)
