The point D(-1,-5) is rooted 180 counterclockwise around the origin what are the coordinates of the ruesulting pointe

D'(1,5)

Step-by-step explanation:

If you rotate a point 180 counter-clockwise around the origin, then it makes the x and y coordinates negative. In this case, it would make the coordinates positive because both coordinates are already negative. The answer would be D'(1,5).

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

not sure but it may be b, as i said i'm not sure.
