X^2 - 10x + 36 = 0;
We use the quadratic formula: x = ( - b + or - i\sqrt{ -b^{2}+4ac })/ (2a);
We have a = 1; b = -10; c = 36;
Then, x = ( 10 + or -i\sqrt{44})/2 = 5 + or - \sqrt{11})/2 ;

What is the image of (-5,-6) after a reflection over the line y=−x?
Nuetrik [128]

Answer:

The image will be the point (6,5)

Step-by-step explanation:

Here, we want to get the image of the point (-5,-6) after the reflection

Mathematically if we reflected a point with the pre-image coordinates (x,y) over the line y = -x; its image becomes (-y, -x)

So, (-5,-6) becomes (6,5)

The table below gives the completion percentage and interception percentage for five randomly selected NFL quarterbacks. Based o
Lina20 [59]

The regression equation is y = -0.42647x + 29.11471 and the correlation coefficient is -0.9607

<h3>How to determine the regression equation?</h3>

The table of values is given as:

Completion Percentage 57 59 62 63 64

Interception Percentage 5 3.5 3 2.5 1.5

Next, we enter the above values in a graphing calculator.

From the graphing calculator, we have the following summary:

  • Sum of X = 305
  • Sum of Y = 15.5
  • Mean X = 61
  • Mean Y = 3.1
  • Sum of squares (SSX) = 34
  • Sum of products (SP) = -14.5
  • r = -0.9607

Regression Equation = ŷ = bX + a

b = SP/SSX = -14.5/34 = -0.42647

a = MY - bMX = 3.1 - (-0.43*61) = 29.11471

So, the regression equation is

y = -0.42647x + 29.11471

And the correlation coefficient is -0.9607
