= mo2-t/h that models the mass remaining after t years.
m(t) =
(b) Find a function m(t) = mọe¯rt that models the mass remaining after t years. (Round your r value to four decimal places.)
m(t) =
(c) How much of the sample will remain after 74 years? (Round your answer to one decimal place.)
g
(d) After how many years will only 2 g of the sample remain? (Round your answer to the nearest whole number.)
