Answer:
Step-by-step explanation:
given that a bacteria population starts with 80 bacteria and doubles every four hours,
The function representing the number of bacteria after t hours
= 
We are to find the inverse of the function
i.e. we must make t = g(n) where g is a function of n.
Take log on both sides.

this is the inverse function.

Answer: 816 years</h2>
This problem can be solved using the <u>Radioactive Half Life Formula:
</u>
<u />
(1)
Where:
is the final amount of the material
is the initial amount of the material
is the time elapsed (the quantity we are asked to find)
is the half life of americium-241
Knowing this, let's find
from (1):
Applying natural logarithm in both sides:
