Answer:
35.34 atoms will be present after 14,325 years.
Step-by-step explanation:
Given : Carbon-14 has a half-life of approximately 5,730 years. This exponential decay can be modeled with the function N(t) = N0. If an organism had 200 atoms of carbon-14 at death.
To find : How many atoms will be present after 14,325 years?
Solution :
The half-life exponential function modeled is [tex]N=N_o(\frac{1}{2})^{\frac{t}{h}}[/tex]
Where, [tex]N_o=200[/tex] is the initial atoms
N is the total number of atoms.
t=14,325 years is the time
h=5,730 years is the half-life time
Substitute the value in the formula,
[tex]N=200(\frac{1}{2})^{\frac{14325}{5730}}[/tex]
[tex]N=200(\frac{1}{2})^{2.5}[/tex]
[tex]N=200(0.1767)[/tex]
[tex]N=35.34[/tex]
Therefore, 35.34 atoms will be present after 14,325 years.
