Which statement best illustrates using the vertical line test to determine if the graph below is a function of x?
A. The graph is not a function of x because the line x = 0 intersects the graph at two points.
B. The graph is a function of x because the line x = 5 does not intersect the graph.
C. The graph is not a function of x because the line y = 0 intersects the graph at two points.
D. The graph is a function of x because the line y = 5 does not intersect the graph.
Answers
Answer:
A
Step-by-step explanation:
Graph is not a function, so B and D are false.
y = 0 is a horizontal line, not a vertical line, so C is false.
This leaves only A.

Find the missing value. 7/8 = x/28.8 Please help, I clearly have no brain cells left, and I have the brain capacity of a Carrot ;-;
Answers
============================================
Work Shown:
7/8 = x/28.8
7*28.8 = 8*x .... cross multiply
201.6 = 8x
8x = 201.6
x = 201.6/8 ... divide both sides by 8
x = 25.2
The missing value of x is 25.2.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let the missing value is x.
Given:
7/8 = x/28.8
7(28.8) = 8x
Cross multiply;
201.6 = 8x
8x = 201.6
x = 201.6/8
Divide both sides by 8;
x = 25.2
Hence, The missing value of x is 25.2.

Two boats, A and B, are approaching a port. The distance between the boats is 12 miles. The bearings of the port with respect to boat A and boat B are N 60° W and N 35° E respectively. How far is boat A from the port? A. 11.02 miles B. 9.87 miles C. 8.23 miles D. 4.54 miles
Answers
The distance from boat A to the port is approximately 5.196 miles.
Let's let point P represent the port.
Here A represent boat A and B represent boat B.
It is also given distance between A and B as 12 miles.
Next, we are finding the angles which boat A and boat B make with the line connecting them.
Let's call this line AB.
We can find these angles by subtracting the given bearings from 180 degrees.
For boat A, the angle it makes with AB is 180° - 60° = 120°
For boat B, the angle it makes with AB is 180° - 35° = 145°
Now we can use trigonometry to find the distance from boat A to the port. Let's call this distance x.
We can use the law of sines, which states
sin A / a = sin B / b = sin C / c
where A, B, and C are angles of a triangle and a, b, and c are the side lengths opposite those angles.
In our case, we can use the angle at boat A (which is 60 degrees) and the angle at the port (which is 120 degrees) along with the side opposite the angle at boat A (which is x) and the side opposite the angle at the port (which is 12-x), sin 60° / x = sin 120° / (12 - x)
We are Simplifying,
√3 / x = √3 / (12 - x)
Multiplying both sides by x(12-x),
12√3 - 3x√3 = x√3
Simplifying further,
12√3 = 4x√3
Dividing both sides by 4√3,
x = 3√3
Therefore, the distance from boat A to the port is approximately 5.196 miles.

Answers
Answer:
Linda, Julie, Jenna, Karl
Step-by-step explanation:
Here, we want to list the students in order from lowest to highest
The key here is to have the scores in the same form, let us say decimals for ease of comparison
Jenna: 85% = 85/100 = 0.85
Linda’s= 32/40 = 80% = 0.8
Karl = 7/8 = 0.875
Julie = 0.83

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is 2/7
There are 16 red marbles in the bag and each is equally likely to be chosen.
Work out how many marbles in total there must be.
Answers
Answer: 56
Step-by-step explanation:
Given that :
Marbles in bag are only red and blue ;
Probability of randomly choosing a red = 2/7
Number of red marbles in bag = 16
The total Number of marbles =?
P(choosing a red marble) = required outcome / Total possible outcomes
Required outcome = number of red marbles
Total possible outcomes = total number of blue and red marbles
Total number of blue and red marbles = x
P(choosing a red marble) = required outcome / Total possible outcomes
2/7 = 16 / x
Cross multiply
2x = 16 * 7
2x = 112
x = 112 / 2
x = 56 marbles
Total number of marbles = 56
the mass of a 30 cm³ stone is 180 g , find it's density
Answers
Answer:
The density of the stone is 6 g/cm³
Step-by-step explanation:
The rule of denisty is d = M ÷ V, where
M is the massV is the volumeLet us use this rule to solve the question
∵ The volume of the stone is 30 cm³
∴ V = 30 cm³
∵ The mass of the stone is 180 grams
∴ M = 180 g
→ Substitute them in the rule above to find d
∵ d = 180 ÷ 30
∴ d = 6 g/cm³
∴ The density of the stone is 6 g/cm³

The weights of dogs at a kennel are Normally distributed with a mean of 18 pounds and a standard deviation of 3.5 pounds.In which percentile is a dog who weighs 25 pounds?
Answers
Answer:
P(x=25)=P(z=2)=0.9972 or 99.72%
Step-by-step explanation:
Mean = 18 pounds
Standard Deviation = 3.5 pounds
x= 25
We need to find P(x=25)
First, we need to find z-score using formula: [tex]z-score=\frac{x-\mu}{\sigma}[/tex]
Finding z-score when x=25
[tex]z-score=\frac{x-\mu}{\sigma}\\z-score=\frac{25-18}{3.5}\\z-score=2[/tex]
So, we need to find P(z=2)=P(x=25)
Looking at z-score table we can find P(z=2)
P(z=2)=0.9972 or 99.72%
So, P(z=2)=0.9972 or 99.72%
Answer:
97.5th percentile

Answers
Answer:
[tex]r\leq 10.8[/tex]
OR
[tex]r\leq 10[/tex]
Step-by-step explanation:
Given that:
Amount of water in the aquarium = 9 gallons
Weight of water in the aquarium = 85 pounds
Total weight that aquarium can hold = 112 pounds
Weight of each rock = 2.5 pounds
To find:
The inequality to find the number of rocks, [tex]r[/tex] that can put in her tank.
Solution:
First of all, let us find more weight that the aquarium can hold after putting the water in the aquarium.
Additional weight that can be put in the aquarium = Total weight - Weight of water = 112 - 85 = 27 pounds
This 27 pounds can be of rocks.
Let the number of rocks that can be put in the aquarium = [tex]r[/tex]
Total weight of [tex]r[/tex] number of rocks = Weight of one rock multiplied by [tex]r[/tex]=2.5[tex]r[/tex]
Now, this weight of rocks must be lesser than or equal to 27 pounds.
Therefore, the in equality is:
[tex]2.5r\leq =27\\\Rightarrow r \leq 10.8\\OR\\\Rightarrow r \leq 10[/tex]
