Select all of the following transformations that would map ΔCDE to ΔTSR. a reflection over the y-axis a reflection over the line x=5.5 a translation of (x, y)→(x+6, y) a rotation of 90° counterclockwise about the point (5.5, 0) a reflection over the line x=4, and a translation of (x, y)→(x+3, y)

The volume of a rectangular pyramid can be found using the formula V = (1/3)*A*H where A is the area of the rectangle base, and H is the height of the pyramid

The length of the base is tripled and the width of the base remains the same. Then, the new area of the base is 3 times the old one.

The height of the pyramid is divided by 7. Then, the new height is the old one divided by 7.

Replacing this in the formula:

V = (1/3)*A*H

V' = (1/3)*(3*A)*(H/7)

V' =   A*(H/7)

where V' is the volume of the new pyramid. Notice that, A and H refer to the original pyramid.

The relationship between these volumes are:

V/V' = [(1/3)*A*H]/[ A*(H/7)] = 7/3

(3/7)*V = V'

So, the volume of the new pyramid is 3/7 times the old one.  

Answer:

8

Step-by-step explanation:

The residual value of 1.3mean when referring to the lineofbestfit of a data set is that a data point is 1.3 units above the line of a data set. This is because the given residual value is positive. So, the data point is above the best fit line.

Residual value:

• A residual value is the standard square error which is calculated from the line of best fit.
• If the residual value 'r' is positive it means the data point is r units above the best fit line.
• If the residual value 'r' is negative it means the data point is r units below the best fit line.

Line of best fit:

A line of best fit refers to a line through a  plot of datapoints that best expresses the relationship between those points.

For the given residualvalue of 1.3 mean, a data point is 1.3unitsabove the line of best fit when referring to the line of best fit of a data set. This is because the residual value is positive.

So, Option A is correct.

Answer:

C.11.2

Step-by-step explanation:

The distance between 2 points is given by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

   = sqrt( ( -2-0)^2 + (-7-4)^2)

   = sqrt( (-2)^2 + (-11)^2)

  = sqrt( 4 + 121)

  = sqrt(125)

 = 11.18033989
