-x -x

y=-x+11 <---- plug in

540=40x+60(-x+11)

540=40x-60x+660

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

Kazeer [188]

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.
