Which rule yields the dilation of the figure RSTU centered at the origin A x y 4x 4y B x y 025x 025y C x y x 4 y 4 D x y x 025 y 025 class=

Respuesta :

Answer: OPTION A.

Step-by-step explanation:

Dilation is defined as  transformations in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure) have the same shape, but their sizes are different.

For a dilation using a scale factor "k" and centered at the origin, the rule is:

[tex](x.y)[/tex] → [tex](kx,ky)[/tex]

Let's pick the point S of the Pre-Image RSTU. This is :

[tex]S(1,1)[/tex]

And the point S' of the Image R'S'T'U' is:

[tex]S'(4,4)[/tex]

You can identify that the coordinates of S' are obtained by multiplying the coordinates of the point S by this scale factor:

[tex]k=4[/tex]

Therefore, the rule that yields this dilation is:

 [tex](x.y)[/tex] → [tex](4x, 4y)[/tex]
