The half-life of carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only 66% of the carbon-1

xz_007 [3.2K]

The tree died about 3357 years ago.

Explanation:

The half life of carbon - 14 is given by

$A(t)=A(0)e^{-kt}$

where $A(t)=0.5$

$A(0)=1$

$t=5600$

Substituting these values in the above equation, we get,

$0.5=1e^{-5600k}$

Taking In on both sides of the equation, we get,

$In(0.5)=-5600k$

$\frac{In(0.5)}{-5600} =k$

$0.00012377=k$

Since, only 66% of Carbon - 14 remains after the time T.

Thus, we have,

$0.66=1e^{-kT}$

Taking In on both sides of the equation, we get,

$In(0.66)=-0.00012377 \ T$

$\frac{In(0.66)}{-0.00012377} = T$

$3357=T$

Thus, the tree died about 3357 years ago.

Though these segments aren't marked congruent in the diagram, the two lines inside the circle making up the bases of the triangles are congruent as all radii are congruent. So the triangles are congruent by SAS.
