For half-life we use the equation A t A_o e kt. You da real mvps.
N 0 the initial quantity of the.
. AtA0 e -rt where At and A0 are amounts of some. Given the half-life find the decay rate. N t N0.
So when were dealing with half life specifically instead of exponential decay in general we can use this formula we got from. One can describe exponential decay by any of the three formulas. Dosage t Dosage 0 05 tT Where.
