In the graph,
Amplitude = 1.5 units
Period = 180°
The x-intercepts are 40°, 140°, 220°, and 320°
<h3>Determining x-intercepts </h3>
From the question, we are to determine the amplitude, period and the x-intercepts of the given graph
Amplitude is the distance from rest to crest.
In the graph,
Amplitude = 1.5 units
Period is how long from crest to crest OR trough to trough
In the graph,
Period = 180°
x-intercepts refers to the points where the graph cuts the x-axis
In the graph,
The x-intercepts are 40°, 140°, 220°, and 320°

Answer: 
Step-by-step explanation:
Given, A class has five boys and nine girls.
Total students = 5+9=14
Number of ways to choose 6 students out of 14= 
[Using combinations]
Number of ways to choose 4 girls out of 6 (4 girls + 2 boys = 6 ) = 
If the teacher randomly picks six students, then the probability that he will pick exactly four girls:-
hence, the required probability = .

Answer:
Um... Don't see the question but here's the answer
Step-by-step explanation
90 has more squares because 0.90 has one more 0 in it and it has 9th of the 10ths than 9
Hello from MrBillDoesMath!
Answer:
Choice e (2a)
Discussion:
a - b = 0 => a = b (*)
So
a + b = (b) + a => commutative property and b = a from (*)
= (a) + a
= 2a
which is Choice e.
Thank you,
MrB
