The question is in the description, it wouldn't fit.

The half-life of cesium-137 is 30 years. Suppose we have a 10-g sample.
1.Find a function
m(t) = m02−t/h
that models the mass remaining after t years.
2.Find a function
m(t) = m0e−rt
that models the mass remaining after t years. (Round your r value to four decimal places.)
3.How much of the sample will remain after 61 years? (Round your answer to one decimal place.)
4.After how long will only 2 g of the sample remain? (Round your answer to the nearest whole number.)
