Answer:
8< (2) ( 7- (2)) = 8<10 which is true
so A. is the answer
Step-by-step explanation:
Answer:
The estimated age of the skull is 39118 years.
Step-by-step explanation:
The amount of the substance after t years is given by:

In which A(0) is the initial amount, and r is the decay rate.
The half-life of carbon-14 is about 5600 years.
This means that
. We use this to find r, or 1 - r, to replace in the equation. So



![\sqrt[5600]{(1-r)^{5600}} = \sqrt[5600]{0.5}](https://tex.z-dn.net/?f=%5Csqrt%5B5600%5D%7B%281-r%29%5E%7B5600%7D%7D%20%3D%20%5Csqrt%5B5600%5D%7B0.5%7D)


So

Only 2% of the original amount of carbon-14 remains in the burnt wood of the campfire.
This is t for which
. So







The estimated age of the skull is 39118 years.

The slope of the line in the function is 1
<h3>Slope of Line</h3>
The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,
m = y₂ - y₁ / x₂ - x₁
Taking two points;
Substituting the values into the formula;
m = -2 - 0 / 3 - 5
m = -2 / - 2
m = 1
The slope is calculated as 1

Answer:
486√3 ft² ≈ 841.8 ft²
Step-by-step explanation:
The area of a regular hexagon with side length s is ...
A = (3√3)/2s²
For the side length of 18 ft, the area is ...
A = (3√3)/2(18 ft)² = 486√3 ft² ≈ 841.8 ft²
