The point A is translated to the point B by the vector (4u above 3u).
|AB| (with arrow on top of AB) = 12.5
I have seen people work this out by doing:
4u^2 + 3u^2 = 12.5^2
16u^2 + 9u^2 = 12.5^2
u = square root of 12.5^2/25
My question is: How do you know that you have to square 4u and 3u??
- Thanks!
