Atriangle has vertices at r(1,1), s(-2,-4) and t(-3,-3). the triangle is transformed according to the rule r0,270.what are the coordinates of s?

D. (4, –2)

Step-by-step explanation:

We are given that,

Triangle RST have vertices R(1, 1), S(–2, –4), and T(–3, –3).

It is given that the function is rotated by 270° about the origin counter-clockwise

This transformation changes the co-ordinates (x,y) to (y,-x).

Thus, the co-ordinates of S' will be obtained by changing the co-ordinates of S = (-2,-4) by the above rule.

Hence, the co-ordinates of S'= (4,-2).

So, option D is correct.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
