Answer:
B and C describe vertical angles
Step-by-step explanation:
Point R will be the common vertex of any possible pair of vertical angles.
For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.
For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.
Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.
__
Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.
Answer:
First, we know that sin330 will be in the 4th quadrant, as it lies between 270 and 360 degrees
Step-by-step explanation:
Answer: A+C=500
7.5A+4.75C=3351.25
C=500-A
7.5A+4.75(500-A)=3351.25
7.5A+2375-4.75A=3351.25
2.75A=976.25
A=355 adults ($2662.50)
C=500-A=145 children ($688.75)
Step-by-step explanation:
Step-by-step explanation:
B: The x axis is the horizontal one. If we look at the graph, there are actually two spots where the line crosses the x axis. It looks to be between -2 and -1 as well as 1 and 2
D: For vertical parabolas such as this, the axis of symmetry is the x coordinate of the vertex. The vertex is essentially the middle point, that, for this graph, is at the bottom. The axis of symmetry is x=0 as that is the x coordinate of the vertex.
E: f(x), in 2D graphs, is typically y, as is the case here. As this parabola opens upward, the minimum point is the vertex, which seems to be -3 for this graph. As the graph seems to be x²-3 or something like that, there is nothing limiting x from being infinity, and when x is equal to infinity in this function, y is as well. Thus, the maximum is infinity.
so your answer should be 9.
