Dimension of an equilateral
Answer:
8.898% will remain after 20000 years.
Step-by-step explanation:
First week need to know the half-life of carbon-14.
In this case it's 5,730 years.
There are calculators available online. (I'm too lazy to run through the equation.) 8.898% will remain after 20000 years.

Answer is -3</h3>
How I got that answer:
The graph shows the two points (0,-4) and (-2,2) are on the parabola. The x coordinates of both points are from x = 0 and x = -2 as given in the instructions. Compute the slope of the line through those points. The slope of this line is the exact same as the average rate of change from x = -2 to x = 0.
m = (y2 - y1)/(x2 - x1)
m = (2 - (-4))/(-2-0)
m = (2 + 4)/(-2-0)
m = 6/(-2)
m = -3
A negative slope means the line slopes downhill as you move from left to right. This is a negative average rate of change.
<u>First row:</u> PERCENT: 140% FRACTION: 7/5 DECIMAL: 1.4
<u>Second row:</u> PERCENT: 4% FRACTION: 1/25 DECIMAL: 0.04
<u>Third row</u>: PERCENT: 56% FRACTION:14/25 DECIMAL: 0.56
<u>Fourth row:</u> PERCENT: 95% FRACTION: 19/20 DECIMAL: 0.95
Hope this helps.
