Which of the following vectors are orthogonal to (-1,3)?
snow_tiger [21]
Any vector that is a multiple of (3, 1) will be orthogonal. These include
.. A (-6, -2)
.. D (3, 1)

_____
The dot-product of these with (-1, 3) is zero:
(-6*-1 +-2*3) = 6 -6 = 0
(3*-1 +1*3) = -3 +3 = 0

You can make a vector orthogonal to a 2-D vector by swapping the coordinates and negating one of them. When you swap the elements of (-1, 3) you get (3, -1). It is usually convenient to negate the one that is already negative, so that would give you (3, 1) as the orthogonal vector.

Jose bought 750 bags of peanuts for $375.00. He intends to sell each bag for $0.15 more than he paid. How much should he charge
svet-max [94.6K]
Answer: $0.65

Explanation: First find how much Jose paid for each bag
$375 / 750
So $0.50 per bag

Now add $0.15 to that
$0.50 + $0.15

That added together is
$0.65

Formula for triangle area = base times height over two. area of smallest triangle: 2*2/2, so 2. area of medium sized triangle: 2*6/2, so 6. the square in between those triangles has an area of four (2*2). the base of the largest triangle is 2+2+6, so 10, and the height is 4. use the formula to find its area is 20. add them all together to get 4+6+4+20 is 34 units^2.
