Which set of ordered pairs represents a function?
1) {(0,4),(2,4),(2,5)}
2) {(6,0),(5,0),(4,0)}
3) {(4,1),(6,2), (6,3),(5,0)}
4) {(0,4),(1,4),(0,5),(1,5)}
Option 1
Answer:
2
Step-by-step explanation:
This is the only set of ordered pairs that represents a function because if this function was graphed, it would pass the vertical line test. Looking at the ordered pairs, a function must not have more than one ordered pair that has the same x-coordinate values. All the other answer choices have 2 or more ordered pairs with the same x-values, meaning 2 is the correct answer.

hale's one-stop gas and auto service compete with Murray's gas and service mart. the local demand is given by P=2.5-0.01Q.
Hale's MC function is MCH: qH=0.35qH
Murray's MC function is MCM: qM=0.3qM
find hale's and Murray's reaction function; then find the Cournot solution. (price and quantities)
The Cournot solution for the price is approximately $2.425, and the quantities produced by Hale and Murray are approximately 3.47 and 4.03, respectively.
To find Hale's and Murray's reaction functions, we need to determine their profit-maximizing quantities given the local demand and their respective marginal cost functions.
Hale's profit function can be expressed as:
πH = (P - MCH) * qH
[tex]= (2.5 - 0.01Q - 0.35qH) * qH\\= 2.5qH - 0.01qH^2 - 0.35qH^2[/tex]
To maximize profits, we take the derivative of πH with respect to qH and set it equal to zero:
dπH/dqH = 2.5 - 0.02qH - 0.7qH
Setting the derivative equal to zero:
2.5 - 0.02qH - 0.7qH = 0
2.5 - 0.72qH = 0
0.72qH = 2.5
qH = 2.5 / 0.72
qH ≈ 3.47
Therefore, Hale's reaction function is qH = 3.47.
Similarly, Murray's profit function can be expressed as:
πM = (P - MCM) * qM
[tex]= (2.5 - 0.01Q - 0.3qM) * qM\\= 2.5qM - 0.01qM^2 - 0.3qM^2[/tex]
To maximize profits, we take the derivative of πM with respect to qM and set it equal to zero:
dπM/dqM = 2.5 - 0.02qM - 0.6qM
Setting the derivative equal to zero:
2.5 - 0.62qM = 0
0.62qM = 2.5
qM = 2.5 / 0.62
qM ≈ 4.03
Therefore, Murray's reaction function is qM = 4.03.
To find the Cournot solution, we substitute the reaction functions into the local demand equation:
Q = qH + qM
Q = 3.47 + 4.03
Q ≈ 7.5
Substituting Q back into the demand equation:
P = 2.5 - 0.01Q
P = 2.5 - 0.01(7.5)
P = 2.5 - 0.075
P ≈ 2.425
The Cournot solution for the price is approximately $2.425, and the quantities produced by Hale and Murray are approximately 3.47 and 4.03, respectively.

usually, data collection in a functional analysis is based on a. duration b. frequency c. momentary time sampling
The correct answer is b. frequency.
Data collection in a functional analysis typically involves recording the frequency of a target behavior. In functional analysis, the focus is on understanding the function or purpose of a behavior, and frequency data helps to identify patterns and determine the relationship between the behavior and environmental events.
During a functional analysis, various conditions are manipulated to assess how they impact the occurrence of the behavior. The frequency of the behavior is typically recorded within each condition to determine if there are differences in its occurrence based on the specific environmental variables being manipulated.
While duration and momentary time sampling are also data collection methods used in behavioral analysis, they are not specifically associated with functional analysis. Duration refers to measuring the length of time a behavior occurs, while momentary time sampling involves recording whether a behavior is occurring or not at specific intervals of time.
In functional analysis, frequency data is typically the primary method for collecting and analyzing data to understand the relationship between behavior and environmental variables.

Data collection in a functional analysis is usually based on three components: duration, frequency, and momentary time sampling. Duration observes the amount of time a behavior occurs. Frequency measures how often a behavior occurs. Momentary time sampling observes the existence of behavior at specified time intervals.
Explanation:In the context of a functional analysis, typically the data collection methods revolve around three primary types: duration, frequency, and momentary time sampling.
Duration refers to the total amount of time that a behavior happens. It generally is measured from the moment the behavior begins until it ends. It's important when the length of time that the behavior occurs can impact its functionality.
Frequency records how often a behavior occurs within a set observational period. It’s used when the number of times the behavior occurs is the important aspect to measure.
Momentary time sampling is a method of measuring behavior in which the existence or nonexistence of behaviors are recorded at precisely specified time intervals. This process involves observing whether the behavior occurs or does not occur at the moment the interval ends. This method is beneficial as it does not need continuous observation.

Step-by
A and C
Two parallel lines are coplanar while two planes that do not intersect are parallel. Options A and C are correct.
What is geometry?It is defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
A line that is in the same plane as another line is said to be coplanar. Any two crossing lines must be coplanar or lying in the same plane.
Since they share the same plane or are in the same plane but never intersect, parallel lines are coplanar.
The planes are parallel if they do not intersect. Due to the endless nature of planes, they cannot meet in a single place. In addition, because planes are flat, they cannot intersect across more than one line.
Thus, two parallel lines are coplanar while two planes that do not intersect are parallel. Options A and C are correct.

A child rolls a ball on a level floor 3.5m to another child. If the ball makes 15.0 revolutions, what is its diameter?
The diameter of the ball is approximately 16.67 meters.
To find the diameter of the ball, we can use the relationship between the distance traveled and the number of revolutions.
The circumference of a circle is given by the formula C = πd, where C is the circumference and d is the diameter.
Given that the ball rolls a distance of 3.5 meters and makes 15.0 revolutions, we can calculate the circumference of the path it travels:
C = 3.5 m * 15.0 = 52.5 m
Since each revolution covers the circumference of the ball, we have C = πd. Plugging in the known value for C, we can solve for the diameter (d):
52.5 m = πd
Dividing both sides of the equation by π, we get:
d = 52.5 m / π
Using a calculator, we can evaluate this expression:
d ≈ 16.67 meters

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. After 15 hours of burning, a candle
has a height of 22 centimeters. After 27 hours of burning, its height is 19.6 centimeters. What is the height of the candle after 23 hours?
Answer:
The height of the candle after 23 hours is 20.4 centimeters
Step-by-step explanation:
Mathematical Modeling
To model a real-life situation, a mathematical model can be built in such a way it accurately represents the variables measured in the system.
This problem requires to build a model for the height of a candle as a linear function of the time it has been burning. If the time is expressed in hours and the height is in centimeters, then the linear function can be written as:
[tex]H(t)=mt+b[/tex]
Where m and b are constants we need to find. We are provided two points of reference: After 15 hours of burning, the candle has a height of 22 centimeters. This is the point (15,22).
We also know after 27 hours of burning, the height is 19.6 cm. This is the point (27,19.6). This data is enough to accurately define the function. Let's substitute the first point:
[tex]22=15m+b\qquad\qquad [1][/tex]
Substituting the second point:
[tex]19.6=27m+b\qquad\qquad [2][/tex]
Subtracting [1] - [2]:
[tex]22-19.6=15m-27m[/tex]
[tex]\Rightarrow 12m=-2.4[/tex]
Solving for m:
[tex]m=-2.4/12=-0.2[/tex]
Using this value in [1]:
[tex]22=15(-0.2)+b[/tex]
[tex]22=-3+b[/tex]
Solving for b:
b=25
The function is now complete:
[tex]H(t)=-0.2t+25[/tex]
Finally, substitute t=23:
[tex]H(23)=-0.2(23)+25=20.4[/tex]
The height of the candle after 23 hours is 20.4 centimeters
