Which shows the image of quadrilateral ABCD after the transformation R0, 90°?
avanturin [10]

Answer:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

Step-by-step explanation:

The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).

The mapping for a rotation through 90° clockwise about the origin is

(x,y)\to ( - y,x)

Therefore:

A(-1,0)\to A'(0,-1)

B(0,-1)\to B'(1,0)

C(-2,-3)\to C'(3,-2)

D(-3,-2)\to D'(2,-3)

Therefore the image rectangle has coordinates:

A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)

The first choice is correct.

Help me order the expressions ! will mark brainliest ! spammers will be reported.
gogolik [260]

Step-by-step explanation:

1) 3^5 × 3^3 = 3^(5+3) = 3^8

=> 3^5 × 3^3 = 3^8

2) 3^3 × 5^3 = (3×5)^3 = 15^3

=> 3^3 × 5^3 < 15^5

3) 3^5 × 5^3 = 3^2×(3^3 × 5^3)

= 3^2 × 15^3 = 9×15^3

=> 3^5 × 5^3 > 15^3
