Find the inner product for (5,-1) * (-3,6) and state whether the vectors are perpendicular. a. 21; no c. - 21; no b. 21; yes d. - 21; yes

c

Step-by-step explanation:

If the dot product of the vectors is zero then they are perpendicular

(5, - 1) • ( - 3, 6)

= (5 * - 3) + ( - 1 * 6) = - 15 + ( - 6) = - 15 - 6 = - 21 ≠ 0

Since product is not zero vectors are not perpendicular
