Answer: 
Step-by-step explanation:
The quadratic equation in its standard form is:
Now, we are given 5 points of the parabola (if you graph a quadratic equation you will have a parabola), however we only need to choose three points to find the coeficients 
, 
and 
in the quadratic equation.
So, let's choose the first three points:
(-1,14):
(1)
(0,7):
(2)
(1,4):
(3)
Substituting (2) in (1) and (3):
(4)
(5)
At this point we have a system with two equations.
Adding (4) to (5):
(6)
Isolating :
(7)
Substituitng (7) in (3):
(8)
Isolating :
(9)
Now we have the three coeficients and we can write the quadratic equation:
Answer:
40
Step-by-step explanation:
So split it into two shapes. Two rectangles.
Rectangle 1 = 4 * 5 = 20
Rectangle 2 = 2 * 10 = 20
20 + 20 = 40
8.3x10^-1, I get 0.8300000000000001 when I use parentheses, the way you have it written, I get NaN
The correct answer for the completion exercise shown above is: "Rectangle".
Then, the complete sentece is: <span>The only way to circumscribe a circle around a parallelogram is to make the parallelogram a rectangle.
The explanation is shown below:
By definition, a parallelogram is a four sided polygon (or a quadrilateral). Therefore, to circumsbribe a circle around this figure, all the vertexes must lie on the circle and it must have four angles of 90 degrees. So, it must be a rectangle. </span>
