Answer:
The 5-hour decay factor is 0.4927.
Step-by-step explanation:
The amount of caffeine in Trent's body decreases exponentially.
The 10-hour decay factor for the number of mg of caffeine is 0.2428.
The 1-hour decay factor is:
[tex]1-hour\ decay\ factor=(0.2428)^{1/10}=0.868[/tex]
Compute the 5-hour decay factor as follows:
[tex]5-hour\ decay\ factor=(0.868)^{5}\\=0.4927[/tex]
Thus, the 5-hour decay factor is 0.4927.
