I don't know how to do this:
Given that P = (5, 9) and Q = (13, 12), find the component form and magnitude of vector PQ. (arrow pointing to the right on top of PQ)

Question

I don't know how to do this: 
Given that P = (5, 9) and Q = (13, 12), find the component form and magnitude of vector PQ. (arrow pointing to the right on top of PQ)

anonymous · Answer

To find the form like the other ones do <x2-x1,y2-y1>

anonymous · Answer

okay, so <8,3> ??

anonymous · Answer

Yes correct that is the component form of the vector. Do you remember how to find the magnitude? We did it in your last question

anonymous · Answer

adding the squares and then taking the square root of the sum?

anonymous · Answer

Yes that is right! And what do you get when you do that?

anonymous · Answer

sqrt(73)

anonymous · Answer

That is the magnitude of it

anonymous · Answer

oh okay so, is the final answer <8,3> sqrt(73) or no?

anonymous · Answer

Yes that is it :)
