Question 605777
solve this equation:
{{{50e^(-0.058x)=100}}} 
divide both sides by 50
{{{e^(-0.058x)=100/50}}}
:
{{{e^(-0.058x)=2}}} 
nat log of both sides
{{{ln(e^(-0.058x))=ln(2)}}}
log equiv of exponents
{{{-.058x*ln(e)=ln(2)}}}
ln of e is 1, therefore
-.058x = ln(2)
x = {{{ln(2)/(-.058)}}}; using a calc
x = -11.9508
