Why do all transformation preserve distance

1 answer:

7 0

Well, a distance-preserving transformation is called a rigid motion, and the name suggests that it moves the points of the plane around in a rigid fashion.

A transformation is distance-preserving if the distance between the images of any two points and the distance between the two original points are equal.

If that's confusing, I get it; basically if you transform something, the points from the transformation are image points. Take the distance from a pair of image points, and take the distance from a pair of original points, and they should be the same for a rigid motion.

I keep emphasizing this b/c not all transformations preserve distance; a dilation can grow or shrink things. But if you didn't go over dilations, don't say nothin XD

erica [24]

Total number of stocks bought = 20
Rate at which each stocks were bought = 31 1/2
   = 63/2
Rate at which 20 stocks were bought = 20 * (63/2) dollars
   = 10 * 63 dollars
   = 630 dollars
Rate at which each stocks were sold = 35 1/4
   = 141/4 dollars
Rate at which 20 stocks were sold = 20 * (141/4) dollars
   = 5 * 141 dollars
   = 705 dollars
Then
Amount of profit made by selling 20 stocks = (705 - 630) dollars
      = 75 dollars
So the total amount of profit made is $75. The correct option in regards to the given question is option "D".

I need help with Question 14 . I need to submit it by monday... Pls help

Answer:

Distance between A and B is 5400 meters

Step-by-step explanation:

Consider "D" the letter to identify distance between A and B

Let's use "t" to identify the time of the first encounter (Devi and Kumar), and create an equation that states that the distance covered by Devi (at 100 m/min) in time "t", is equal to the total distance D minus what Kumar has covered at his speed (80 m/min) in that same time:

Recall that distance equals the speed times the time:

distance= speed * time

First encounter:

100 * t = D - 80 * t

180 * t = D Equation (1)

Not, 6 minutes later (at time t+6) , Devi and Li Ting meet .

Then for this encounter the distance covered by Devi equals total distance d minus the distance covered by Li Ting:

100 *(t+6) = D - 75 * (t+6)

100 t + 600 = D - 75 t - 450

175 T + 150 = D Equation (2)

Now, let's equal equation (1) to equation (2), since D should be the same:

180 t = 175 t + 150

5 t = 150

t = 30

Then the time t (first encounter) is 30 minutes. Knowing this, we can use either equation to find D:

From Equation (1) for example: D = 180 * t = 180 * 30 = 5400 meters

The Alpitude is 5 because that is what the positive slope is. The Vertex is (2,6) because that is the lowest point on the graph. The equation is

y=5lx-2l-6 (lx-2l reprsents the absolute value of x-2)
