Use the law N = c(t)^d
at t = 1, N = 1.7
at t = 2, N = 2.4
at t = 3, N = 2.9
at t = 4, N = 3.4
Solve for c and d.
I've been trying to do this for a while, but not sure how to solve it.
HI
Are c and d both constants ? If so ..
$\displaystyle N=ct^d$
When t=1 , N=1.7
$\displaystyle 1.7=c(1)^d$ , one to the power of anything would give you 1 .
c=1.7
at t = 2, N = 2.4
$\displaystyle 2.4=1.7(2)^d $
$\displaystyle 1.41=2^d$
$\displaystyle d=\frac{\ln 1.41}{\ln 2}$
