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:
1. 2/1 its easy.
Step-by-step explanation:
X^2 - 6x + 5 = 0
(x - 5)(x - 1) = 0
x - 5 = 0; x =5
x - 1 = 0; x = 1
answer
x = 1, x =5
It's C, that is decreeing from y =4 to y=3
3x+1=43
3x=42 (take one from each side)
x=14 (divide each side by 3)
the answer is 14
