Question

How do you solve half life decay problems?

Answer 1

`f(x)=a*0.5^(t//t_"1/2")`

Explanation:

In the equation above, `a` represents the number of starting unstable atoms, `0.5` represents a loss of `50%` of the current unstable atoms, `t_"1/2"` represents a half-life time (usually in seconds, days, weeks, months or years), and `t` represents the total time passed.

For example, `t/t_"1/2" = "9 days"/"3 days"` represents a 3-day half-life passing three times.
