11.The components of vector A and vector B are:

Ax = + 7.6 Bx = −3.8
Ay = -9.2 By = +4.6

Which equation describes the relationship between the two vectors?

12. A vector of components (6, 2) is multiplied by the scalar value of 3. What is the magnitude and direction of the resultant vector?

Ax = + 7.6 Bx = −3.8
Ay = -9.2 By = +4.6

A-7.6B=-3.8

A+9.2B=4.6

-7.6B-9.2B=-3.8-4.6

-16.8B=-8.4

B=0.5

A-(7.6*0.5)=-3.8

A-3.8=-3.8

A=0
