Answer:
1 and 4 are Vertical
Step-by-step explanation:
<span>Vector Ā * Vector B = -10. This is the scalar dot product and can calculated by taking the magnitude in the x, y, and z of the two vectors and the operation is done.
The angle </span> Ɵ AB between vector Ā and vector B is 133.635°.
<span>2 Vector B * 3 Vector C = -1. A similar approach is done for this one.</span>
Given: 5x-y=4. Create a couple of ordered pairs by choosing x and calculating y from this equation:
x=1 results in y=1. Thus, (1,1) is a solution.
x=-3 results in -15-y=4, or -y=19, or y=-19. Thus, (-3,-19) is a solution.
x=0 results in -y=4, so that y=-4. Thus, (0,-4) is a solution.
x + 3y <= 191
x = children
y = adults (x3)
So adding those two up must be either less than or equal to 191, as that is all the Chef made.
