At death means x= 0, so on the graph you can see that (0, 500), so 500 carbon atoms are present at death.

Plug 11,240 in for t in the equation, and you are left with N(t) = 500(1/2)^2 = 125 carbon atoms.

See the graph point (25,000, 24.298)? That means that after 25,000 years 24.298 carbon atoms will be present. So the answer is 25,000 years.

I need help with this
Kruka [31]

Answer:

<h2>V = 235.5 in³</h2>

Step-by-step explanation:

The formula of a volume of a cylinder:

V=\pi r^2H

r - radius

H - height

From the pictue we have r = 5in and H = 3in. Substitute:

x=\pi(5^2)(3)=\pi(25)(3)=75\pi\ in^3

\pi\approx3.14

Therefore

x=(75)(3.14)=235.5\ in^3
