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.

The question is actually:

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

The person accidentally put 2 instead of -2.

Therefore, the equation is ⇒ (7 × 0) + (2 × (-2)) ⇒ 0 + (-4) ⇒ -4

Now, it is not perpendicular because the vectors are only perpendicular when their inner product is 0.

Answer: A) -4; no
