Use the data in the table below and a graphing calculator to describe how a linear model compares to a quadratic model. Analyze
Delvig [45]

The quadratic model and the linear model of the table of values are the same

<h3>The linear model of the data</h3>

To do this, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

  • Sum of X = 0
  • Sum of Y = 113
  • Mean X = 0
  • Mean Y = 22.6
  • Sum of squares (SSX) = 10
  • Sum of products (SP) = 28

The regression equation is

y = mx + b

Where

m = SP/SSX = 28/10 = 2.8

b = MY - bMX = 22.6 - (2.8*0) = 22.6

So, we have:

y = 2.8x + 22.6

See attachment for graph (1)

<h3>The quadratic model of the data</h3>

To do this, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

  • a = 0
  • b = 2.8
  • c = 22.6

0 X^2 +2.8 X +22.6

The regression equation is

y = ax^2 + bx + c

So, we have:

y = 0x^2 + 2.8x + 22.6

See attachment for graph (1)

<h3>Why both graphs look the same</h3>

The graphs look the same because when the quadratic model is simplified, it gives the linear model.

This in other words mean that:

The quadratic model and the linear model of the table of values are the same

Find the equation of the line perpendicular to y=-4x+3 that also intersects the point (8,1)
Fudgin [204]

Answer:

-1

Step-by-step explanation:

They already did the opposite reciprocal for you.

They have it in the form y=\frac{1}{4}x+b now.

To find b you just enter (x,y)=(8,1).

Let's do that.

1=\frac{1}{4}(8)+b

1=2+b

Subtract 2 on both sides:

-1=b

b=-1
