Question

Please helpp



Given a dilation around the orgin, what is the scale factor K?
Do, K= (2,4) → (3,6)

a. 2
b. 3.2
c. 2/3
d. 3

Answer 1

The total linear displacement is the length:
\(\Delta l=\sqrt{\Delta x^2 + \Delta y^2} = \sqrt{1^2+2^2}\)
The dilation is the displacement divided by the magnitude of the original vector.

Answer 2

Do you know how to find a vectors magnitude?

Answer 3

Not really

Answer 4

You need to study. I think the answer should be 1.5

Answer 5

Alright. thank you.

Answer 6

No problem.
