Math Problem Statement

Solution

To assist you with the problem shown in the image, I need to know the relative angles between the vectors. Unfortunately, without the figure, I can't directly observe the angles.

However, you can help me by describing the angles between the vectors in the xy-plane:

  1. Are the vectors orthogonal (perpendicular) to each other?
  2. Are the vectors pointing in the same or opposite directions?
  3. Are there any known angles between the vectors?

With this information, I can guide you through determining whether the dot products are positive, negative, or zero.
