Question

HELP PLEASE!!
Consider the vector v= (-7,8)?
A. What is the angle between v=(-7,8) and the positive x-axis?

Part 1: Use the formula V1 V2 = | V1 || V2 | cos(theta) to find the cosine of the angle between the two vectors (-7,8) and (1,0)

B. Write V in the form ( | V | cos(theta), | V | sin(theta) )

Part 1. Find the Magnitude of vector V. Express your answer in radical form.

Part 2. Use the Magnitude and the angle of vector V to write it in the form ( | V | cos(theta), | V | sin(theta) )

C. What is the angle between v= (-7,8) and w =(5,3)

Part 1. Use the formula V1 V2 = | V1
