exponential decay formula half life. So were starting off with well were starting off with N sub 0 times e to the minus-- wherever you see the t you put the minus 5730-- so minus k times 5730. To find the half-life of a function describing exponential decay solve the following equation.

To find the half life of a substance or the time it takes for a substance to decrease by half youll be using a variation of the exponential decay formula. The decay law calculates the number of undecayed nuclei in a given radioactive substance. The coefficient a represents the starting amount.
Solution for Find the associated exponential decay or growth model.
Where N 0 is the initial quantity N t is the remaining quantity after time t t 12 is the half-life t is the mean lifetime l is the decay constant. Below are shown three equivalent formulas describing exponential decay. So this tells us that after one half-life-- so t is equal to 5730. Thanks to all of you who support me on Patreon.
