![**Radioactive Decay Model**
This exercise uses the radioactive decay model.
The half-life of cesium-137 is 30 years. Suppose we have a 17-g sample.
(a) Find a function \( m(t) = m_0 2^{-t/h} \) that models the mass remaining after \( t \) years.
\[ m(t) = \boxed{} \]
(b) Find a function \( m(t) = m_0 e^{-rt} \) that models the mass remaining after \( t \) years. (Round your \( r \) value to four decimal places.)
\[ m(t) = \boxed{} \]
(c) How much of the sample will remain after 84 years? (Round your answer to one decimal place.)
\[ \boxed{} \, \text{g} \]
(d) After how many years will only 2 g of the sample remain? (Round your answer to the nearest whole number.)
\[ \boxed{} \, \text{yr} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F004f485a-dc8e-4d2a-a997-494cbc4bff99%2Fc213618d-dffb-49ac-9b06-d265ce6c69be%2Fh808aom_processed.png&w=3840&q=75)
