The frequency of the sinusoidal graph is 3 Hz.
<h3>What is frequency of sinusoidal graph?</h3>
The frequency of a sinusoidal graph is the number of complete waves for every 2π units.
The frequency of the sinusoidal graph is determined by counting the number of complete waves from 
to 
units.
From a sketch of the graph;
Thus, the frequency of the sinusoidal graph is 3 Hz.

Answer:
$3,100.
Explanation:
Given that tuition for one year at Mount Tusk University is $ 13,400, and Elijah has saved $ 1,800 for this year's tuition, while his parents have agreed to pay $ 5,000 this year, and he earned a football scholarship for $ 3,500, given that Elijah hopes to earn the rest of the money through his work-study job tutoring in the math center, to determine how much money does Elijah need to earn tutoring, the following calculation must be performed:
13,400 - 1,800 - 5,000 - 3,500 = X
11,600 - 5,000 - 3,500 = X
6,600 - 3,500 = X
3,100 = X
Thus, Elijah needs to earn $ 3,100 in his work-study job.
The best way is: B. flat, so that the north pole of the magnets on the train point up and the north poles of the magnets on the track point down.
<h3>What is the law of magnetism?</h3>
The law of magnetism states that the like poles of a magnet repel one another while unlike (different) poles attract each other. Thus, two north (N) poles of a magnet would repel one another while a north (N) and south (S) would attract each other.
Based on the law of magnetism, the best way to arrange the magnets on the train and on the track, so as to allow the model train levitate is flat, as this would make the north (N) pole of the magnets on the train point up and the north (N) poles of the magnets on the track point down.

<u>Complete Question:</u>
Jolie builds a model of a maglev train. She uses disc magnets to levitate the train. A disc magnet has its north and south poles on its faces, as shown.
What is the best way to arrange the magnets on the train and on the track so that the model train levitates?
The probability would be 1/36
Explanation:
A longitudinal wave is composed of compressions and rarefactions. An example of a lomgitudinal wave is sound waves. It's a type of wave thay moves parrelel to axis.
