Question 1129328
<br>
If the half life is 4.536 days, then 1 day is 1/4.536 of a half life.<br>
Then the amount left after 1 day is<br>
{{{(.5)^(1/4.536)}}} = 0.8583 to 4 decimal places.<br>
The daily decay rate is then 1-0.8583 = 0.1417.<br>
The decay rate as a decimal is 0.1417; as a percent it is 14.17%.
