Since we are given with the identity of the chemical as Carbon-14, we obtain the half-life of the chemical from a reliable source and get a value of 5730 years. The equation that we are going to use for this item is,
A(t)/A(0) = (0.50)^(n/5730)
where A(t) is the current amount, A(0) is the initial amount and n is the number of years. We know from the given that the ratio of A(t) and A(0) is equal to 0.63. Substituting this to the given,
0.63 = 0.50^(n/5730)
n = 3819.48
Thus, the sample is approximately 3819.5 years old.

The equation of line is:

Further explanation:
The standard form of equation in point-slope form is:

Given equation is:
3x+2y=10
We have to convert it into point slope form, for which we have to isolate y on one side of equation

Comparing with standard form:
m = -3/2
As the new line is parallel to given line, their slopes will be equal
So,

To find the value of b, putting the given point (4,-5) in equation
