Amplitude - It is the magnitude of an oscillation. In addition, it is also used to refer to Jacobi amplitude.
Period - The intervals where the periodic function recur.
Frequency - The number of occurrences within the given period of time.
Good luck :)

Hey do you need to show your work for these? I found an answer key
Step-by-step explanation:
We need to use law of cosines
c²=a²+b²-2abcos(C)
let x= angle xzy
plugging in what we have the equation looks like
17²=22²+20²-2*22*20*cos(x)
289=484+400-880cos(x)
.676136364=cos(x)
x=47.45754235
b.)
The smallest angle should be opposite to the smallest side
Using the law of cosines again we get
9²=13²+17²-2*13*17*cos(x)
81=458-442cos(x)
.852941176=cos(x)
x=31.46697634
The complete factorized expression is
(2 + 2a + 3b) (2 - 2a + 3b).
Take a look at the attachment to see how I got this solution.
According to the question statement, the total sum of students is 221, which includes the students that ride on bus and the students that ride in a van.
The students that ride in a van are five, the students that ride on bus are 6 times s which is the product of the number of buses and the number of students that are on each bus.
Write all this information into an equation, this way:
Now, solve the equation for s to find the number of students that are on each bus.
There are 36 students on each bus.
Answer:
729 people chosen
Step-by-step explanation:
4 calculations in head when 3^2 = 9
3 calculations in head when 3^3 = 27
2 calculations in head when 3^4 = 81
1 calculations in head when 3^5 = 243
Answer found 3^6 = 729.
3 = 1st = 3^1
9 = 2nd = 3^2 3(3)
27 = 3rd = 3^3 9(3)
81 = 4th = 3^4 27(3)
243 = 5th = 3^5 81(3)
729 = 6th = 3^6 243(3)
