I used the formula and got sqrt13? but I have no clue what I use that for lol...

vectors, right ?
anonymous
  • anonymous
yeah @ganeshie8

  • anonymous
Ok so I did some research of how to get it and I got mag of sqrt89 does that seem right?
ganeshie8
  • ganeshie8
first find the component form, then you need to take mag of component form
anonymous
  • anonymous
Ok ! To find vectors you should go with another way ...!
anonymous
  • anonymous
how do I do that? see what I did was I did sqrt(Q1-PI)^2+(Q2-P2)^2
ganeshie8
  • ganeshie8
P = (-5, 5) and Q = (-13, 10) component form : <-13--5, 10-5> <-13+5, 5> <-8, 5>
ganeshie8
  • ganeshie8
thats the component form. to find component form of a vector when its points are given, simply subtract
ganeshie8
  • ganeshie8
now, for mag, take mag of <-8, 5> mag = \(\large \sqrt{x^2+y^2} = \sqrt{(-8)^2+5^2}\) simplify
anonymous
  • anonymous
see I did that but it wasn't an option so now I am really confused xD LOL
anonymous
  • anonymous
since it says mag 2 should I multiply <-8,5> by two?
ganeshie8
  • ganeshie8
Yes ! after taking the mag, multiply it by 2
anonymous
  • anonymous
so it would be sqrt178 and <-16,10>
anonymous
  • anonymous
:DDD!?
ganeshie8
  • ganeshie8
2PQ = \(\large 2 \times \sqrt{(-8)^2 + 5^2 }\)
anonymous
  • anonymous
is that right?? :D
ganeshie8
  • ganeshie8
that should give you 2 x sqrt(89) = 18.87
ganeshie8
  • ganeshie8
is that one of your options ha ? :)
anonymous
  • anonymous
Yeah it is!!!! !:DDDDD THANK YOU SOOOOO MUCH! !<3

wonderful !!! you wlcme :)
