What is the scale factor in the dilation if the coordinates of A' are (-7, 6) and the coordinates of C’ are (-4.3)? a. 1/3
b. 1/2
c. 2
d. 3

  a.  1/3

Step-by-step explanation:

For dilation about the origin, the ratio of any pair of corresponding coordinates will give you the scale factor:

  A'y/Ay = 6/18 = 1/3

The scale factor is 1/3.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
