A dilation image of triangle PQR with a scale factor 4 and center at the origin is drawn. The image is triangle POR'.
What is the ratio of the length of P'Q to the length of O'R'?
O A 1:1
OB. 4:1
O c. 8:1
OD. 16:1

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

a² + b²= c²

24² + 7² = c²

c= 25

16.9 times 2.85

step-by-step explanation:

its c or d   take a lucky guess my dude
