Want this question answered?
If the original point was (-4, 12) then the image is (-16, 48).
similar
None. The vertices, the scale factor as well as the centre of dilation can each be defined independently of the other two. Each different combination will result in a different image.
A translation of 4 units to the right followed by a dilation of a factor of 2
The 3 transformations of math are: translation, reflection and rotation. These are the well known ones. There is a fourth, dilation, in which the pre image is the same shape as the image, but the same size in the world
it is nothing
If the original point was (-4, 12) then the image is (-16, 48).
Yes, it is.
Because the image is not the same size as the preimage. To do a dilation all you do is make the image smaller or larger than it was before.
Dilation - the image created is not congruent to the pre-image
Dilation
The image is a similar shape to that of the original.
Dilation.
Image over preimage(original)
With a scale factor of 1, the image is exactly the same size as the original object.
Negative
A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image. The image always has a prime after the letter such as A' . resource: http://www.mathwarehouse.com/transformations/dilations/dilations-in-math.php
