Identify the function with a period of 4 and an amplitude of 2.
Answer:
it's only 2pi/B because the period of sin and cos is 2pi. If we were dealing with tan it'd be pi/B, since the period of tan is just pi.

A box contains colored jelly beans. There are 14 red, 6 yellow, and x blue jelly beans in the bag. If the probability of drawing a yellow jelly beans is 1/4, what is the value of x?
Answer:
4
Step-by-step explanation:
If the probability of drawing a yellow jelly beans is 1/4, the box is has 1/4 yellow jellybeans.
1/4b=6
b=24
14+6+x=24
20+x=24
x=4
Answer:
36 blue jelly beans
Step-by-step explanation:
We can find the total number of jelly beans by adding all red, yellow, and blue jelly beans together.
14+6+x
This simplifies to 20+x
For probability, it is (the number of things you want)/(the total number of things there are).
If the probably of drawing a yellow jelly bean is 1/4, we can set up this equation:
[tex]\frac{14}{20+x}=\frac{1}{4}[/tex]
We can cross multiply:
[tex]20+x=14(4)\\x+20+56\\x=36[/tex]
There are 36 blue jelly beans.

Would you choose to use a histogram, a circle graph, or a line graph to display the data? Explain your choice. Then make a display.
The data should be displayed using a line graph, as shown in the attached figure.
Definition of a Line Graph
In a line graph, also known as a line plot or a line chart, each data point is connected by its own line. A line graph displays numerical values across a chosen time span.
Why is a line graph the best choice in this situation?
A line graph would be the best option for showing the data for David's family's grocery spending over the previous 10 weeks because it would show us the trend in the data.

Answer:
4. b) an angle
5. b) the angles of a triangle
6. b) opposite, hypotenuse and adjacent
Step-by-step explanation:
4. To find sine, cosine, tangent, you use the sin, cos, tan key of the calculator.
If you are given the value of the sin, cos, tan, and you are looking for the angle, then you use the second function of the calculator.
Answer: b) angle
5. angles of a triangle
6. The sides that form the right angle are the legs. In trig, there is an angle of interest, so to distinguish between the legs, one leg is called the adjacent leg, and the other leg is called the opposite leg. The side opposite the right angle is the hypotenuse.
Answer: opposite, hypotenuse and adjacent

3a) The coordinate of R after dilation is; R' = (-6, 21)
3b) The coordinate of T after dilation is; T' = (1, 3)
5) A dilation by a scale factor of 2 followed by a translation right 1 up 3.
How to carry out dilation in Transformation?3a) We are given the coordinates of the rectangle as;
Q(-2, -1), R(-2, 7), S(4, 7), T(4, -1)
Now, we are told that R(-2, 7) is dilated about the origin with a scale factor of 3. Thus;
R' = (-2 *3), (3 * 7)
R' = (-6, 21)
3b) We are now told that T(4, -1) is dilated by a scale factor of 1/2 with R as center of origin. R has a coordinate of (-2, 7). Thus;
Coordinate of T' = (-2, 7) + ¹/₂((4, -1) - (-2, 7))
Coordinate of T' = (-2, 7) + ¹/₂(6, -8)
Coordinate of T' = (-2, 7) + (3, -4)
Coordinate of T' = (1, 3)
5) We can see that LN is 2 units while L'N' is 4 units and so we can say scale factor in the transformation of ΔLMN to ΔL'M'N' is 2.
Now, if we apply scale factor of 2 to coordinates of N before transformation, we will have; 2(3, 1) = (6, 2)
Comparing to N' which is (5, 5) we can say that it was shifted up by 3 units and right by 1 unit.

If ABC is reflected across the y-axis, what are the coordinates of C?
A. (6,-3)
B. (3,-6)
C. (-6,-3)
D. (-6,3)
Answer:
Step-by-step explanation:
The correct answer would be C (-6,3). The y axis is the bold line going up and down on the middle of the page. If you were able to pick up triangle and flip it over the y axis. Point C would land at (-6,3).
Also, you can see that point C is six spaces to the right of the y axis. That means when we flipped it over the axis, it will now be six paces to the right of the y axis. Since the point did not go up or down when you flipped it. It is still 3 spaces above the x axis.
Answer:
D (-6, 3)
Step-by-step explanation:
the point C is originally (6, 3).
that means the x coordinate is 6, the y coordinate is 3.
now, if we reflect (= mirror) that point across the y axis, that means we mirror it to the other side of the y axis.
the y axis is the vertical coordinate axis in the middle of the graph.
so, what is going to happen to the point ?
will the y coordinate change ? no. the point will move over to the other side of the y line in the same "height" as before. nothing will move it higher or lower.
so, it will keep the same y coordinate : 3.
will the x coordinate change ? oh, yes. because the point will move from the right of the y axis to the left of the y axis. and it will be the same distance to the left as it was originally to the right.
so, +6 turns into -6 (as the y axis represents x=0).

The shallowest section of an underground tunnel is -50 feet. The deepest section of the tunnel is -135 feet. How many feet below the shallowest section is the deepest section?
A. -95 feet
B. -185 feet
C. 85 feet
D. 195 feet
Answer:
c
Step-by-step explanation:
1) eliminate the negative answers since we need the amount of feet below a section and a negative number below a section doesn't make sense in this context and would result in a distance higher than the shallowest section.
Just find the absolute value or the difference between 135 and 50 resulting in 85

What is dot plot?Generally, Data points are represented as dots on a graph with an x- and y-axis in a dot plot sometimes referred to as a strip plot or dot chart, which is a straightforward kind of data visualization.
The frequency table displays the number of ill patients in each age group. The first two plots are incorrect because the sum of the dots connecting the numbers 24, 25, 26, 27, 28, and 29 in the first two plots is 3, but not in the other two plots.
In conclusion, there are only 4 ill individuals when the dots from the 30-34 age range on the first plot are added together. There are a total of 6 cases in that age group on the second graph. As a result, the second dot plot is the one that matches the frequency table.

The polynomial is P(z) = 5z * (z - 1) and the equivalent forms are P(z) = 5z^2 - 5z and P(z) = -5z + 5z^2
How to create the polynomial?The GCF is given as:
GCF = 5z
This means that the polynomial can be represented as:
P(z) = GCF * Another factor
We can make use of the following function
P(z) = 5z * (z - 1)

Both systems have an infinite number of solutions.
The system of equations has more solutions.
The system of inequalities has more solutions.
Both systems have only one solution.
we conclude that the system of inequalities has more solutions than the system of equations.
What can we conclude about the two given systems?We have the system of equations:
y = (-1/2)*x + 1
y = x - 5
And the system of inequalities:
y > (-1/2)*x + 1
y < x - 5
First, if you look at the first system you can see that we have two non-parallel lines, so that system has only one solution.
Now let's look at the system of inequalities, we can get solutions like:
x = 10
y = 1
1 > (-1/2)*10 + 1 = -4
1 < 10 - 5 = 5
So both inequalities are true, which means that the point (10, 1) is a solution.
And also is the point (11, 1), and (12, 1), and infinite other points.
Then we conclude that the system of inequalities has more solutions than the system of equations.
