Select the best answer to complete the sentence. A Rigid Motion or Isometry ______________________.
Dmitry_Shevchenko [17]

Answer: A. preserves length, angle measures and distance between points

Rigid motions or isometries are any of the three transformations below

  • translation (aka shifting)
  • rotation
  • reflection

Any of those three transformations will keep the figure the same size and shape. That means distances between any two points are kept the same, and angle measures are kept the same as well. Everything is kept the same. The only difference is that the figure is in a different location, is rotated somehow, or it is reflected some way. You can use a series of transformations to undo everything to get the original figure back.

If you wanted to change the size of the figure, then you would apply dilation, which isn't an isometry.

Two cylinders are similar. The radius of cylinder a is 5.6 in. The radius of cylinder b is 1.4 in. If the hwight of cylinder b i
sleet_krkn [62]
The answer is 16in.

Let the radius and height of cylinder A be Ra and Hb respectively and the radius and height of cylinder B be Rb and Hb respectively.

Using similar shapes:
Ra/Ha= Rb/Hb
5.6/Ha=1.4/4
Ha=(4×5.6)/1.4
Ha=22.4/1.4
Ha=16in

Does it matter which coordinate is (x1,y1) and (x2,y2) or can I just choose which coordinate I want it to be?​
zubka84 [21]

Answer:

Technically not on a graph but on a table yes it matter but here if I were you I would do (2,2) and (-1,-4)

Step-by-step explanation:   y=mx+b

(2,2) and (-1,-4)                  2=2(2)+b                     Answer is: y=2x+(-2)

x1 y1         x2 y2                2=4+b

-4-2=-6                           -2=b

-1-2=-3                    y-intercept

m=2

slope
