Question 1193732
Problem description indicates the model form must be {{{A(t)=A[o]e^(kt)}}}  form.
Use the half life fact to find the value for k.


{{{1*e^(kt)=1/2}}}

{{{e^(kt)=1/2}}}

{{{ln(e^(kt))=ln(1/2)}}}

{{{kt=-ln(2)}}}

{{{k=-ln(2)/t}}}

{{{highlight_green(k=-ln(2)/36.1)}}}

{{{highlight(k=-0.01920)}}}


----


{{{highlight(A(t)=A[o]e^(-0.01920t))}}}
