Using an exponential function, it is found that the bottle contains 255,960 atoms of tritium after 11 years.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem:
- The bottle initially contained 450,000 tritium atoms, hence A(0) = 450000.
- The amount decays by about 5% per year, hence r = 0.05.
Thus, the equation is given by:



After 11 years, the amount is given by:

The bottle contains 255,960 atoms of tritium after 11 years.

Answer:
20% of the invited people did not attend
Step-by-step explanation:
5 out of 25 people invited didn't attend Glen's party. That means the following:
people didn't come which simplifies to 
Multiply
by the giant one
so the denominator is 100 which is the denominator used to find percentages.
You end up with 
= 20%
That equation is unable to be graphed because a ^ cant be near -<span />
