Write the vector v in the form aiplusbj, given its magnitude left norm Bold v right norm and the angle alpha it makes with the positive x-axis. Left norm Bold v right normequals12, alphaequals150

Step-by-step explanation:

Given:

The magnitude, v=12

The angle it makes with the positive x-axis =

Now for a vector (x,y)

Therefore:

Similarly:

Recall that:

Therefore:

The vector in the form ai+bj is therefore:

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
