Answer: last one
Step-by-step explanation:
The equation is a scientific law, Newton's Law of Gravity,
![F =\dfrac{GMm}{r^2}](https://tex.z-dn.net/?f=F%20%3D%5Cdfrac%7BGMm%7D%7Br%5E2%7D)
This is a pretty bad question. Newton's Law of Gravity is a mathematical model of gravitation, originally a theory, verified by observation, and now superseded by the General Theory of Relativity.
C is probably the best answer to this poor question.
The image of the dilation is shown below, with the centre of dilation (0,0) and scale factor of 3
The coordinate of C' is (6, -3) which is three times of the coordinate of C(2, -1)
