Which transformations could be performed to show that Triangle ABC is similar to Triangle A''B''C''? A. a reflection over the x-axis, then a dilation by a scale factor of 3

B. a reflection over the x-axis, then a dilation by a scale factor of 1/3

C. a 180° rotation about the origin, then a dilation by a scale factor of 3

D. a 180° rotation about the origin, then a dilation by a scale factor of 1/3

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

i think it is c hope that

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
