Line segment df on a coordinate plane with d at 0 comma 4 and f at 3 comma 2 segment df is dilated from the origin to create segment d prime f prime at d′ (0, 6) and f′ (4.5, 3). what scale factor was segment df dilated by? 0.75 1.3 1.5 2.5

1.5

Step-by-step explanation:

We know that when a figure is dilated from the origin , then the scale factor if dilation is the ratio of the coordinate of image to the pre-image.

Given : line segment DF on a coordinate plane with D at (0,4) and F at (3,2) segment DF is dilated from the origin to create segment D prime F prime at D′ (0, 6) and F′ (4.5, 3).

Then, the scale factor will be :-

Therefore, the required scale factor = k= 1.5

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

i do not know this sorry : (
