Question

For the half life: the half life is the solution (t) of the equation: a/2= ae^-3.392t

Answer 1

The given equation for the half life is

`(a)/(2) =a e^(-3.392t)`

Divide each side by a to obtain

`(1)/(2)= e^(-3.392t)`

Take the natural log of each side to obtain
ln(1/2) = -3.392t
Therefore

`t= (ln(1/2))/(-3.392) =0.2043`

Answer: t = 0.2043
