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.

A rectangle's length, x, is 2 meters greater than its width. If the perimeter of the rectangle is greater than 112 meters, what

kotykmax [81]

Assume widthis x-2
perimeter is 2*(width+length)
so 2*(x+x-1)>112
2*(2x-1)>112
4x-2>112
x>28.5
so any length greater than 28.5 will work
