Question

Find the inner product for (7,2) • (0,2) and state whether the vectors are perpendicular

Answer 1

Answer:

• 4
• not perpendicular

Step-by-step explanation:

The inner product is the sum of products of corresponding components:

  (7,2) • (0,2) = 7·0 +2·2 = 4

The inner product is 4, which is not zero, so the vectors are not perpendicular.
