The smaller triangle is a dilation of the larger triangle with a center of dilation at (2,−1) . what is the scale factor of the dilation? a. 13 b. 12 c. 2 d. 3

1/2

Step-by-step explanation:

dilation often means multiplying. it says "dilation of the larger triangle"

the larger triangle has a side of 6 units.

the smaller triangle has a side of 3 units.

if you multiply 6 by 0.5, you get 3.

even though the number gets smaller, you are still multiplying.

now, if it said "dilation of the smaller triangle," we'd have a different answer. in that case, we would have to divide 6 by 3 to get 2.

the answer is 1/2

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

40 x 50 = 2000
