Answer:
x = 6 7/9
Step-by-step explanation:
Any triangle inscribed in a circle with one side being a diameter is a right triangle.
9x - 14 = 180 - 90 - 43
9x - 14° = 47°
9x = 61°
x = 6 7/9
Number twenty-one is one and three-fourths
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.
Answer:
8 pounds
Step-by-step explanation:
As you know from Part A, 0.5 pounds is one dollar. You want to know how many pounds cost $4. You can fill in the first and second blanks with this information.
