The age of the radioactive artifact is approximately 19029.6 years old
<h3>Radioactivity</h3>
Radioactivity is the phenomenon of the spontaneous disintegration of unstable atomic nuclei to atomic nuclei to form more energetically stable atomic nuclei. Radioactive decay is a highly exoergic, statistically random, first-order process that occurs with a small amount of mass being converted to energy.
To solve this problem, we have to find the disintegration constant and we can use the formula of half-life of the sample to do that.
The half-life of a sample is given as;
The formula of radioactivity is given as
Substituting the values into the equation
The artifact is approximately 19029.6 years.

You don't have the question out for me to answer so could you add the question to this like a picture or something?
Since you didn't put the solutions I'll just explain how to answer it. Most likely the answers are in (x,y) form. Just substitute x and y into the equation and then solve. If it is true it is a solution.
Example: 2x ≥ 4x - 2
A. 1
2(1) ≥ 4(1) - 2
2 ≥ 4 - 2
2 ≥ 2
In this instance A would be a correct answer.
(If you would like me to actually answer the question than you will need to include the answer choices.)
10xX+15 =11X
10X+15=11X
-10X -10X
15=1X
X=15
