Select all tables that represent a proportional relationship between X and Y
Answer:
The 'constant of proportionality k' DOES NOT remain constant for all the points in the table.
Therefore, the table DOES NOT represent a proportional relationship between X and Y.
Step-by-step explanation:
We know that when y varies directly with x, we get
y ∝ x
y = kx
k = y/x
where k is called the 'constant of proportionality'.
Given the table
x 0 5 10 15
y 2 17 32 47
Let us calculate the k value for all the points
FOR (0, 2)
k = y/x
substitute x = 0, and y = 2
k = 2 / 0 = ∞
FOR (5, 17)
k = y/x
substitute x = 5, and y = 17
k = 17/5
k = 3.4
FOR (10, 32)
k = y/x
substitute x = 10, and y = 32
k = 32/10
k = 16/5
k = 3.2
FOR (15, 47)
k = y/x
substitute x = 15, and y = 47
k = 47/15
k = 3.1
It is clear that the 'constant of proportionality k' DOES NOT remain constant for all the points in the table.
Therefore, the table DOES NOT represent a proportional relationship between X and Y.

y2 = - 2
y1 = 2
x2 = 3
x1 = 0
Formula
m = (y2 - y1)/(x2 - x1)
Solution for m
m = (-2 - 2)/(3-0)
m = -4/3
Solution for the line
m = - 4/3
y intercept = 0,2

Safe wheelchair ramp specifications require about 4.75° maximum angle to be constructed with the ground. At a particular building, the owner is installing a wheelchair ramp that needs to rise 1 feet off the ground. The owner insists on constructing the angle with the ground at 3°. How much horizontal distance will the ramp cover with these specifications?
Answer:
The ramp must cover a horizontal distance of approximately 19.081 feet.
Step-by-step explanation:
Given the vertical distance ([tex]y[/tex]), measured in feet, and the angle of the wheelchair ramp ([tex]\theta[/tex]), measured in sexagesimal degrees. The horizontal distance needed for the ramp ([tex]x[/tex]), measured in feet, is estimated by the following trigonometrical expression:
[tex]x = \frac{y}{\tan \theta}[/tex] (1)
If we know that [tex]y = 1\,ft[/tex] and [tex]\theta = 3^{\circ}[/tex], then the horizontal distance covered by this ramp is:
[tex]x = \frac{1\,ft}{\tan 3^{\circ}}[/tex]
[tex]x \approx 19.081\,ft[/tex]
The ramp must cover a horizontal distance of approximately 19.081 feet.

If a proportional relationship has a constant of proportionality of 6, what is a point that lies on the graph of
the line representing the relationship?
Answer:
(0,0) (1,6) (2,12)
Step-by-step explanation:
Proportional relationships are also known as direct variation, so I'll refer to it as DV.
The formula for finding DV is y=kx.
In this case, k=6, which is just y=6x. So, essentially..
(0,0) (1,6) (2,12) etc.
The points that lies on the graph of the line representing the relationship are (0, 0), (1, 60, and (2, 12).
What is Constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
As, we know that the constant proportionality have
y= k x
where k is constant of proportionality.
We have given that constant of proportionality = 6
So, y= 6x
Now, when x=0
y=0
and, x=1
y= 6
and, x=2
y= 12
Hence, the points are (0, 0), (1, 60, and (2, 12).

Two students flipped a coin 100 times and recorded the results. Find the experimental probability of flipping the coin and getting tails.
Answer:
I'm not too sure about this one, but I think it's 36% since that's
how many they got when they flipped the coin. In reality, it's 50% for both sides.

What is the difference between (-10)² & -10²? What are the values for each expression?
Answer:
(-10)² = 100
-10² = -100
Difference = 200
Step-by-step explanation:
For the individual expressions;
(-10)² = -10 * -10
(-10)² = +100
For -10²
-10² = -(10*10)
-10² = -100
Taking the difference;
(-10)² - (-10²) = 100 - (-100)
(-10)² - (-10²) = 100 + 100
(-10)² - (-10²) = 200
Hence the difference is 200

Zachary and his children went into a grocery store and will buy bananas and peaches.
Each banana costs $0.50 and each peach costs $1.50. Zachary has a total of $8 to
spend on bananas and peaches. Write an inequality that would represent the possible
values for the number of bananas purchased, b, and the number of peaches
purchased, p.
Answer:
0.5b + 1.5p ≤ 8
Step-by-step explanation:
The inequality function is as follows:
Let us assume the number of bananas acquired be b
And, the number of peaches acquired be p
Cost of each banana be $0.50
ANd, the cost of each peach be $1.50
Also the total would be $8
The possible values of banana is 0.5b
And, for peaches it would be 1.5p
So, the inequality function is
0.5b + 1.5p ≤ 8
Answer:
0.5b + 1.5p ≤ 8

An elevator in a mine shaft is stopped at a .25 feet below ground level. And then travels 28 feet downward. What equation can be written to find the final position in feet of the elevator in relations to ground level?
Correct question:
An elevator in a mine shaft is stopped at 25 feet below ground level. And then travels 28 feet downward. What equation can be written to find the final position in feet of the elevator in relations to ground level?
Answer:
-53 feets
Step-by-step explanation:
Initial stop point = 25 feets below ground level
Further distance traveled = 28 feets below ground level
Final position in feet = Initial stop point + further distance traveled
Note : distances or point traveled below ground level or downward is represented as negative.
Final position in feets = (-25)feets + (-28)feets
Final position in feets = - 53 feets

If a line has a slope of 9/5. If one of the points on the line is (-10, -16), which could be another point?
Answer:
(–5, –7)
Step-by-step explanation:
From the question given above, the following data were obtained:
Slope = 9/5
Coordinate 1 = (–10, –16)
x₁ = –10
y₁ = –16
Coordinate 2 = (x₂, y₂)
Next, we shall determine the change in x and y coordinate. This can be obtained as follow:
Slope = change in y–coordinate / change in x–coordinate
Slope = Δy / Δx
Slope = 9/5
9/5 = Δy / Δx
Thus,
Δy = 9
Δx = 5
Next, we shall determine the second coordinates as follow:
Δy = y₂ – y₁
Δx = x₂ – x₁
For x–coordinate:
x₁ = –10
Δx = 5
Δx = x₂ – x₁
5 = x₂ – (–10)
5 = x₂ + 10
Collect like terms
x₂ = 5 – 10
x₂ = – 5
For y–coordinate:
y₁ = –16
Δy = 9
Δy = y₂ – y₁
9 = y₂ – (–16)
9 = y₂ + 16
Collect like terms
y₂ = 9 – 16
y₂ = – 7
Coordinate 2 = (x₂, y₂)
Coordinate 2 = (–5, –7)
