D. a line graph
Step-by-step explanation:
Answer:
Option A. ![10\ units^{2}](https://tex.z-dn.net/?f=10%5C%20units%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of the rectangle is equal to
A=LW
where
L is the length of rectangle
W is the width of rectangle
we have
![A(-3,1),B(-2,-1),C(2,1),D(1,3)](https://tex.z-dn.net/?f=A%28-3%2C1%29%2CB%28-2%2C-1%29%2CC%282%2C1%29%2CD%281%2C3%29)
Plot the vertices
see the attached figure
L=AD=BC
W=AB=DC
the formula to calculate the distance between two points is equal to
<em>Find the distance AD</em>
![A(-3,1),D(1,3)](https://tex.z-dn.net/?f=A%28-3%2C1%29%2CD%281%2C3%29)
substitute in the formula
<em>Find the distance AB</em>
![A(-3,1),B(-2,-1)](https://tex.z-dn.net/?f=A%28-3%2C1%29%2CB%28-2%2C-1%29)
substitute in the formula
Find the area
![A=(2\sqrt{5})*(\sqrt{5})=10\ units^{2}](https://tex.z-dn.net/?f=A%3D%282%5Csqrt%7B5%7D%29%2A%28%5Csqrt%7B5%7D%29%3D10%5C%20units%5E%7B2%7D)
To find the missing values, find the slope of the equations. Since both equations are linear, we know that the slope is linear. We can find the slope of the equations by using the equation for slope.
Slope for Y1:
m = (y2 - y1) / (x2 - x1) = (11 - 15) / (-3 - -5) = -4 / 2 = -2
Therefore, for Y1, you can subtract 2 from each previous answer to fill in the column. So underneath 15 would be 13, then 11, then 9, etc.
Slope for Y2:
m = (y2 - y1) / (x2 - x1) = (-12 - -15)) / (-4 - -5) = 3 / 1 = 3
<span>Therefore, for Y2, you can add 3 from each previous answer to fill in the column. So underneath -15 would be -12, then -9, then -6, etc.</span>
4000 * .02= 80. 80 * 2.5= 200. 2.5 years.
