Which of the relations given by the following sets of ordered pairs is not a function?
Answers
{(−4,−2),(−1,−1),(3,2),(3,5),(7,10)}{(−4,−2),(−1,−1),(3,2),(3,5),(7,10)} ordered pairs is not a function. A mapping between two sets, which is a relation and can potentially be a function, can be represented by a set of ordered pairs.
Which relation is not a function?A relationship is not a function if each input does not have a distinct output. For a relation to be a function, each input must have a distinct output, and the order of the set's items must be paired in a unique way or the elements of sets must be mapped in a unique way.A function is a special type of relation in which each element in the domain is paired with exactly one element in the range. For example, the relation {(1, 2), (3, 4), (5, 6)} is a function because each element in the domain (i.e., {1, 3, 5}) is paired with exactly one element in the range (i.e., {2, 4, 6}). On the other hand, the relation {(1, 2), (3, 4), (1, 6)} is not a function because the element 1 is paired with two elements in the range (2 and 6).All the set ot values agrees with this definition except the B, because the third and fourth pair have the same first value (3)Complete question :

The lower and upper estimates of a car coming to a stop six seconds after the driver applies the brakes are as follows: Lower estimates = 122 Upper estimates = 298 Question: On a sketch of velocity against time, show the lower and upper estimates.
Answers
These lines will be parallel to the initial line and will intersect the final velocity line at the corresponding values (122 for the lower estimate and 298 for the upper estimate)
To sketch the velocity against time, you can take the following steps:
First, calculate the acceleration using the given data by using the formula;
acceleration = (final velocity - initial velocity)/time
Where; Initial velocity is the velocity before applying the brakes
Final velocity is the velocity at which the car comes to stop
Time is the time it takes to stop the car (6 seconds in this case)
Now, calculate the lower and upper estimates using the formula;
Lower estimate = initial velocity + (acceleration x time)
Upper estimate = initial velocity + (2 x acceleration x time)
Sketch the graph using the following steps;
On the vertical axis, plot the velocity of the car
On the horizontal axis, plot the time
Start from the initial velocity and draw a straight line with the calculated acceleration until the end of the time (6 seconds)This straight line will give you the final velocity (0 in this case)
Now, draw two more lines, one with the lower estimate and the other with the upper estimate
Finally, label the axes and the lines with their corresponding values.'

A meter stick casts a shadow 2.75 meters. a nearby tree casts a shadow that is 47.2 meters. find the angle of elevation as well as the height of the tree.
Answers
We have x = 2.75 meters for the meter stick's shadow and the tree's shadow length is 47.2 meters.
To find the angle of elevation and the height of the tree, we can use similar triangles and trigonometric ratios.
Let's denote the height of the tree as h and the length of the meter stick's shadow as x. According to the given information, we have x = 2.75 meters for the meter stick's shadow and the tree's shadow length is 47.2 meters.
Using the concept of similar triangles, we can set up the following proportion: h / x = tree's height / tree's shadow length
Substituting the given values, we have: h / 2.75 = tree's height / 47.2
To find the angle of elevation, we can use the tangent function: tan(angle) = tree's height / meter stick's height
Substituting the values, we have: tan(angle) = h / 2.75
To solve for the angle, we can take the inverse tangent (arctan) of both sides: angle = arctan(h / 2.75)

a) 7.2 b) 7.4 c) 7.5 d) 7.8
Answers
Nora could run 7.5 minutes per mile to qualify for the state cross-country championships. The correct answer is option c.
To qualify for the state cross-country championships, Nora needs to run 4 miles in 30 minutes or less. So, her average rate should be:
average rate = total time / total distance
If she runs at the slowest rate possible to still qualify, then her average rate would be:
average rate = 30 / 4 = 7.5 minutes per mile
Therefore, the correct option is c) 7.5.
If she runs slower than this average rate, then her total time would exceed 30 minutes and she would not qualify.

Jacob is training for a marathon. His plan is to run the same distance for 3 days a week, then increase that distance by the same amount each week of training. During week 6, Jacob runs 14 miles per day, which is 1. 5 miles more per day than he ran during week 5. Which equation represents the daily running distance, in miles, as a function of time, t, in weeks? f(t) = 0. 5t 7 f(t) = 0. 5t 11 f(t) = 1. 5t 5 f(t) = 1. 5t 12. 5.
Answers
f(t) = 3.1667 + 10.8333t, 3.1667 represents the distance Jacob ran during week 5, and 10.8333 represents the increase in distance per week.
Given that Jacob runs 14 miles per day during week 6 and 1.5 miles more per day than he ran during week 5, we can determine the distance he ran during week 5.
Let's say Jacob ran x miles per day during week 5. Therefore, during week 6, he ran x + 1.5 miles per day.
To find the value of x, we know that during week 5, Jacob ran the same distance for 3 days a week. So, the total distance for week 5 would be 3 times the distance he ran each day: 3x.
Similarly, during week 6, Jacob also ran the same distance for 3 days a week, resulting in a total distance of 3 times the distance he ran each day: 3(x + 1.5).
We are given that the total distance for week 6 is 14 miles per day, so we have the equation:
3(x + 1.5) = 14
Expanding and simplifying the equation:
3x + 4.5 = 14
3x = 14 - 4.5
3x = 9.5
x = 9.5 / 3
x = 3.1667 (approximately)
Therefore, Jacob ran approximately 3.1667 miles per day during week 5.
Now, let's find the equation that represents the daily running distance, in miles, as a function of time, t, in weeks.
We know that the distance increases by the same amount each week. So, the increase in distance from week 5 to week 6 is (14 - 3.1667) = 10.8333 miles.
Since Jacob plans to increase the distance by the same amount each week, we divide the increase by the number of weeks:
Increase per week = 10.8333 / (6 - 5) = 10.8333
Therefore, the equation that represents the daily running distance, in miles, as a function of time, t, in weeks is:
f(t) = 3.1667 + 10.8333t
In this equation, 3.1667 represents the distance Jacob ran during week 5, and 10.8333 represents the increase in distance per week.

Steve and Stephanie need to complete 4 hours of housework for their allowances to be equal.
What is equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
Let 'x' represents the Steve's weekly allowances and 'y' represents the Stephanie's weekly allowance.
Let h represent the number of hours.
Steve receives $15 plus $1.25 for every hour he completes housework.
So, we get an equation,
⇒ x = (1.25)h + 15
Stephanie receives $5 for every hour she completes housework.
So, we get an equation,
⇒ y = 5h
We need to find the number of hours of housework they need to complete for their allowances to be equal.
When their allowances are equal,
⇒ x = y
⇒ (1.25)h + 15 = 5h
⇒ 3.75 h = 15
⇒ h = 4 hours
Therefore, they need to complete 4 hours of housework for their allowances to be equal.

The y-intercept represents the initial temperature of the liquid before cooling and the slope represent the changes in temperature for every m minutes.
y = 100 - 5m
where
y = temperature in degree Celsius
m = cooling for number of minutes
Using the slope intercept equation,
Slope intercept;y = mx + bwhere
m = slope
b = y-intercept
Therefore,
y - intercept = 100
slope(m) = 5
Therefore, the y-intercept represents the initial temperature of the liquid before cooling and the slope represent the changes in temperature for every m minutes.
