A line segment in the coordinate plane has endpoints at A(-2,7) and B(3,7). If AB is dilated by a factor of 4 with a center origin, which of the following is the length of its imagine A'B'? 1) 16 3) 24
2) 20 4) 28

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06
