Answer:
(- 10, 45 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply each of the coordinates by the scale factor, that is
(- 2, 9 ) → (- 2 × 5, 9 × 5 ) → (- 10, 45 )
Lets just choose the first one, 3 4 and 5. According to the Pythagorean Theorem,
a^2+b^2=c^2
So lets plug in our numbers.
3^2+4^2=c^2
The answer should be 5, but lets make sure.
3*3 = 9
4*4 = 16
9+16=c^2
25 = c^2
Square root both sides so:
5=c
And sure enough 5 is the last number on that list. The order doesn’t matter as long as the value you are trying to find is the c^2.
