What is the scale factor of the dilation
2 answers:
Answer: The answer is 2.
Step-by-step explanation: We are given to find the scale factor for the dilation of a triangle shown in the figure.
The triangle ABC is dilated to form the triangle A'B'C'.
To find the scale factor, we need to divide the length of one side of the dilated triangle A'B'C' by the length of the corresponding side of the original triangle ABC.
From the figure, we note that
AB = 5 units and A'B' = 10 units.
Therefore, the scale factor will be
Thus, the answer is 2.

The probability that Terri chooses a blue pen is 2/7. The probability that Terri chooses a red pen is 4/7. The probability that Terri chooses neither a red nor blue pen is 1/7.
2/7 x 4/7 x 1/7 = 0.02332

The distance between the points C(-3,1) and D(5,6) is 10.3 units.
<u>Step-by-step explanation:</u>
Let us consider CD is a line segment.
The point C is (-3,1) and D is (5,6).
The Cartesian formula for line is used to find the length between the CD.
Distance between two points = .
The points are (-3,1) and (5,6).
