Question 1042662
Question 1 looks like exponential growth, but you might want instead of the unknown E base, to use a more typical e base, approximately or close to 2.71828 something.  Write a better shown equation format {{{N=N[o]e^(kt)}}}.


Your given data is population goes from 2 million to 32 million in 80 years.
Question first asks, find k.


{{{ln(N)=ln(N[o])+ln(e^(kt))}}}
{{{ln(N)=ln(N[o])+kt*ln(e)}}}
{{{kt+ln(N[o])=ln(N)}}}
{{{highlight(kt=ln(N)-ln(N[o]))}}}  OR  {{{highlight(kt=ln(N/N[o]))}}}
and you can use either of these to find a formula for k or for t.


TO get the value of k in question 1, make these substitutions after solving the formula for k:
{{{system(N=32,N[o]=2,t=80)}}}.
