Answer:
Period = pi
Angular frequency = 2
Amplitude = 5
Midline is the line y = 3
Step-by-step explanation:
A sinusoidal wave is written in the general form as:
f(x) = A*cos(w*x) + C
Where:
- A is the amplitude.
- w is the angular frequency, this is equal to 2*pi/T
where T is the period.
- y = C is the midline.
Then in the equation:
f(x) = 5*cos(2*x) + 3
- 5 is the amplitude.
- 2 is the angular frequency (in the image is called frequency, but this quantity must be in radians/time, while the normal frequency is only in Hz)
- We know that the angular frequency is equal to 2*pi/T, whit this eqation we can find the period:
2 = 2*pi/T
T = 2*pi/2 = pi
pi is the period.
- y = 3 is the midline.

2m(3m+4p)
Step-by-step explanation:
Key Skills are: Factoring, GCF, and Simplifying
We have the expression 6[tex]m^{2}[/tex] + 8mp.
1) We want to find the greatest factor among both terms (1 of the terms is 6m^2 and the other is 8mp).
2) Both of these terms have a factor of m, and both are divisible by 2.
3) Therefore, you can take out 2m and get 2m(3m+4p)

QRST is a rectangle. If RT = 4x - 16 and SQ = x + 5, find the value of x.
Answers
Answer:
The value of x is 7.
Step-by-step explanation:
Both RT and SQ are diagonals of the rectangle, so they have the same measure.
We have that:
[tex]RT = 4x - 16, SQ = x + 5[/tex]
Since they are equal:
[tex]4x - 16 = x + 5[/tex]
[tex]4x - x = 5 + 16[/tex]
[tex]3x = 21[/tex]
[tex]x = \frac{21}{3}[/tex]
[tex]x = 7[/tex]
The value of x is 7.

What word describes the slopes of the line
Answers
Answer:
Positive
Step-by-step explanation:
There are a couple ways we can go about this.
First, we can see that as x increases, so does y, so that means its positive
For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place
If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.
We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.
fine the lower and upper quartiles and interquetile range.
5, 12, 17, 23, 28, 31, 37, 41, 42, 49, 54, 58, 65, 68, 73, 71.
Answers
Answer:
Lower Quartile = 25.5
Upper Quartile = 61.5
IQR = 36
Step-by-step explanation:
Given data is:
5, 12, 17, 23, 28, 31, 37, 41, 42, 49, 54, 58, 65, 68, 73, 71
The lower quartile is the first quartile and upper quartile is the third quartile.
A median divides the data set in two equal halves.
Lower quartile also known as first quartile is the middle value in the first half.
The first half is:
5, 12, 17, 23, 28, 31, 37, 41
As the number of values is even, the quartile will be the average of two middle values
[tex]Q_1 = \frac{23+28}{2} =\frac{51}{2}= 25.5[/tex]
Upper quartile is the average of middle two values in the second half when the number of values is even.
42, 49, 54, 58, 65, 68, 73, 71
[tex]Q_3 = \frac{58+65}{2} = \frac{123}{2} = 61.5[/tex]
Interquartile range is the difference of third quartile and first quartile
[tex]IQR = Q_3 - Q_1 = 61.5-25.5=36[/tex]
Hence,
Lower Quartile = 25.5
Upper Quartile = 61.5
IQR = 36

An equation for a vertical line that contains E(-7,-1)
Answers
Answer:
The equation of the line containing the point (-7, -1) will be:
x = -7The graph of the vertical line containing the point (-7, -1) is also attached below.
Step-by-step explanation:
Given the point
E(-7, -1)It means:
at x = -7, the value of y = -1.
Given that the line is vertical. It means no matter what the value of y is, the value of x remains the same.
In other words, the value x does not change for any value of y.
Therefore, the equation of the line containing the point (-7, -1) will be:
x = -7The graph of the vertical line containing the point (-7, -1) is also attached below.

If m< XYZ= 136, solve for x
Answers
Answer:
x = 3
Step-by-step explanation:
We'd apply some properties of rhombus.
m<RZT = (10x - 8)°
m<ZRY = 90° (diagonals bisect at 90°)
m<ZYR = ½(m<XYZ) = ½(136) = 68°
m<RZT + m<ZRY + m<ZYR = 180° (sum of ∆)
(10x - 8) + 90 + 68 = 180
Solve for x
10x - 8 + 90 + 68 = 180
10x + 150 = 180
10x = 180 - 150 (subtraction property of equality)
10x = 30
Divide both sides by 10
x = 3
The value of x is 3
The calculation is as follows:m<RZT = (10x - 8)°
m<ZRY = 90° (diagonals bisect at 90°)
m<ZYR = ½(m<XYZ) = ½(136) = 68°
Now
m<RZT + m<ZRY + m<ZYR = 180° (sum of ∆)
(10x - 8) + 90 + 68 = 180
10x + 150 = 180
10x = 30
x = 3
