Question 152841
{{{R=4520(0.75)^(2.5T)}}}
{{{lnR=ln4520+2.5Tln0.75}}}
Solving for T,we have
{{{2.5Tlno.75=lnR-ln4520}}}
{{{T=(lnR-ln4520)/(2.5ln0.75)}}}
{{{T=(ln(R/4520))/(2.5ln0.75)}}}
Substituting R = 1950 into the formula and evalute, we have
{{{T=(ln(1950/4520))/(2.5ln0.75)=(-0.841)/(2.5*(-0.288))=1.168}}}
