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:
Option B. Amplitude =3 midline is y =2.
Step-by-step explanation:
In the graph attached we have to find the amplitude and midline of the periodic function.
Amplitude of the periodic function = (Distance between two extreme points on y asxis)/2
= (5-(-1))/2 = (5+1)/2 =6/2 =3.
Since amplitude of this function is 3 and by definition amplitude of any periodic function is the distance between the midline and the extreme point of wave on one side.
Therefore midline of the wave function is y=2 from which measurement of the amplitude is 3.
Answer:
Step-by-step explanation:
412 is a whole number, 638 is the number you want to look at.
your answer is 412 638/1000
or 412 63.8/100
hope this helps
