Question

Given that P = (-5, 11) and Q = (-6, 4), find the component form and magnitude of vector QP.

<-11, 7>, square root of 38
<-1, -7>, square root of 50
<1, 7>, 50
<1, 7>, square root of 50

Answer 1

So to add vectors together, we merely add the components.

We have to vectors \(\large (P_x , P_y)\) and \(\large (Q_x , Q_y)\)

so to add and find the resultant vector, we add \(\large (P_x + Q_x, P_y + Q_y)\)
