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
<u>Answer:</u>
f (x, y) = 40x + 25y
<u>Step-by-step explanation:</u>
We are given that Efficient Homemakers Ltd. makes canvas wallets and leather wallets as their project.
Assuming to be the number of leather wallets and to be the number of canvas wallets, we are to write a function showing their total profit for both wallets.
Profit on canvas wallet () = $25
Profit on leather wallet () = $40
<u>Total profit from both wallets:</u>
f (x, y) = 40x + 25y
