Put it in the calculator it should go in as
y=(x-2)+2
Answer:
E) 79.7 cm^2
Step-by-step explanation:
This is really messy so I think the choices are A) to E) only
I think its 6cm 7.2cm 2.8cm 10cm
1. Multiply all
6 * 7.2 + 2.8 * 10 > 70
2. Around 79.7
The answer is 11 i
<em /><em>Explanation:
</em>
The square root needs to be a number that can be multiplied by itself and equal the original number.
In this case, the number is 11, 11*11 = 121
However, you are looking for the square root of a negative number, due to this you would add i to the answer,
i = imaginary number, or -
( Depending on your grade/ teacher however, you can put "no solution"
Given:
The three points are (-7,134), (-3,10) and (5,50).
To find:
The equation of parabola using quadratic regression.
Solution:
The general equation of quadratic regression is
...(i)
The three points are (-7,134), (-3,10) and (5,50).
Using the graphing calculator, we get a=3, b=-1 and c=-20. Putting these values in (i), we get
![y=3x^2+(-1)x+(-2)](https://tex.z-dn.net/?f=y%3D3x%5E2%2B%28-1%29x%2B%28-2%29)
![y=3x^2-x-2](https://tex.z-dn.net/?f=y%3D3x%5E2-x-2)
Therefore, the equation of parabola is
and the missing values in the given equation are 3, -1 and -20.
