find the component form and magnitude of PQ (-> over PQ)

Question

Given that P = (5, 9) and Q = (13, 12), 

Answer 1

Given that p =  (5 , 9) and Q =  (13 , 12)

The component form is

Vector PQ = Q - P

                = < 13 - 5 , 12 - 9 >

                = < 8 , 3 >

The magnitude vector is obtained by formula

Therefore the component vector is < 8 , 3 > and magnitude of the vector is 8.544
