for half lifes
y=ae^-bx

Answers

ansver

Answer from: josecano2

A is the initial population

b is the decay coefficient

X is normally the time.

$Y = Ae^{-bx}$

then is the population half of the initial population of A

for half life you will have

$\frac{Y}{A} = \frac{1}{2}$

so the equation becomes

$\frac{1}{2} = e^{-bX}
\\
\\\ln{ \frac{1}{2}} =\ln{e^{-bX}}
\\
\\ \ln{1}-\ln{2}=-bX
\\bX=\ln{2}$
