7. Use the dot product to determine which of the following vector pairs are orthogonal.

A. V1=(22,15) and v2=(-2,4)

Part 1: Multiply the two x-coordinates of the vectors and the 2Y coordinates of the factors. Write each product below. (2 points)

Part II: add the two products together. What is the result? (2 points)

Part III: are the two vectors orthogonal? (2 points)
