Is the relation a function:

To determine if the relation is a function, we need to check if there is exactly one output for each input.

Looking at the given set of points, we see that there are two points with an x-coordinate of -1: (-1, 3) and (-1, -2).

This means that there are two outputs for the same input, so the relation is not a function.

Therefore, the correct answer is: "No, because for each input there is not exactly one output."

The graph can be used to determine how many gallons of water will be left in the pool.  It can also be used to estimate the rate of decrease of water in the pool over time.

The given graph shows the relationship between the number of gallons of water remaining in the pool and the number of hours the pool has drained. As time passes, the number of gallons of water in the pool decreases.

The graph shows an exponential decay function, where the number of gallons of water remaining in the pool decreases rapidly at the beginning, then the rate of decrease slows down over time. This is because the amount of water draining from the pool depends on the amount of water remaining in the pool. As the amount of water decreases, there is less water to drain, and the rate of decrease slows down.

The graph can be used to determine how many gallons of water will be left in the pool after a certain amount of time, or how long it will take to drain the pool completely. It can also be used to estimate the rate of decrease of water in the pool over time.

Step-by-step explanation:

Answer:

A. C + 364 = 500

Step-by-step explanation:

There is a very small chance (less than 1%) that a randomly selected baby from this sample was born on Tuesday OR on Friday.

To find the probability that a randomly selected baby from this sample was born on Tuesday OR on Friday, we need to add the number of babies born on Tuesday to the number of babies born on Friday, and then divide by the total number of babies in the sample.

The number of babies born on Tuesday is 202020, and the number of babies born on Friday is 151515. Therefore, the total number of babies born on Tuesday or on Friday is 202020 + 151515 = 353535.

The total number of babies in the sample is 500500500. Therefore, the probability that a randomly selected baby from this sample was born on Tuesday OR on Friday is:

353535 / 500500500 = 0.0007061

It is interesting to note that the number of babies born on different days of the week varies in this sample. For example, there are more babies born on weekdays (Monday-Friday) than on weekends (Saturday and Sunday), and there are more babies born on Tuesday than on Wednesday or Thursday.

The number of scheduled deliveries is higher than the number of unscheduled deliveries overall, but there are some days (e.g., Friday and Saturday) where there are more unscheduled deliveries than scheduled deliveries. These patterns could be explored further to understand the factors that influence the timing and scheduling of deliveries.

so, m∠2= 90-62=28°

Step-by-step explanation:

Answer: All im gonna say is you can take out 28 and 118 because there is nothing you can do correctly to get those as your answer.

Answer:

No. See explanation

Step-by-step explanation:

No, a rectangle and a parallelogram have different formulas for area.

The formula for the area of a rectangle is:

A = l x w

Where A is the area, l is the length, and w is the width.

The formula for the area of a parallelogram is:

A = b x h

Where A is the area, b is the base, and h is the height.

In a parallelogram, the base and the height are perpendicular to each other, while in a rectangle, the length and width are perpendicular to each other.

Answer:

No

Step-by-step explanation:

A trapezoid is a parallelogram but uses the formula

Given :

A cashier at Giorgio's Grocery Store gets paid $8 per hour for shifts of 6 hours or less.

And $12 per hour for working shifts over 6 hours long.

To Find :

A function best represents this situation.

Solution :

Let, number of hours is h and amount paid is y .

For, h ≤ 6

y = 8h

For, h > 6

y = 12h

Therefore, function representing this is :

y( h ) =  8h  , x ≤ 6

            12h , x > 6

Hence, this is the required solution.

A relation's origin is represented as an ordered pair.

(-5, -2), (-4, -4), (-3, 4), (-2, 2), (2, -2) are all ordered pairs that reflect the same function (4, 3)

A composite of the x coordinate and the y coordinate, an ordered pair has two values that are stated in a defined order between parenthesis. In order to have a better understanding of what is being shown on the screen, it is helpful to identify a point on the Cartesian plane.

Either of the following conditions must be true for an ordered pair to constitute a function:

Every x-value has precisely one matching y-value, or "one-to-one."

This is a many-to-one relationship, meaning that several x-values map to the same set of y-values.

The ordered pair is not a function if and only if both of the following are false

A one-to-many relationship means that for every x-value, there may be many y-values.

Many x-values map to many y-values; the relationship is many-to-many.

Only the ordered pair (5, -2) meets the criteria for a function out of the possibilities (5, -4), (3, 4), (2, -2), (4, 3), and (-4, -2).

This is because no x-values in its range have more than one associated y-value.

One-to-many and many-to-many ordered pairings make up the rest of the set.

The value of the angle 4 is 96 degrees as shown in the diagram.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things.

From the given diagram, the measure of angle 1 and 3 are equal as well as 2 and 4.

Given the following angles

m<3 = 84 degrees

Since the measure of <3 and <4 lies on the same straight line, hence:

m<3 + m<4 = 180

84 + m<4 = 180

m<4 = 180 - 84

m<4 = 96 degrees

Hence the measure of angle 4 from the figure is 96 degrees

The probability is calculated using the formula P(s) = (k-1)^(s-1) * (m-k+1) / m^s, where m represents the total number of tags available.

The problem can be approached using a geometric distribution, as we are interested in the number of trials (tag draws) required to achieve a certain sum (at least k). In this case, the probability of success on each trial is p = (k-1) / m, as there are (k-1) successful outcomes (tags that contribute to the sum) out of the total number of tags available, m.

The probability mass function of a geometric distribution is given by P(X = s) = p^(s-1) * (1-p), where X is the random variable representing the number of trials required.

Applying this to the given problem, the probability of taking s tag draws to accumulate a sum of at least k can be calculated as P(s) = (k-1)^(s-1) * (m-k+1) / m^s. Here, (k-1)^(s-1) represents the probability of s-1 successes (draws that contribute to the sum) out of s-1 trials, and (m-k+1) represents the probability of success on the s-th trial. The denominator, m^s, represents the total number of possible outcomes on s trials.

Using this formula, you can write a function with the necessary inputs (m, k, and s) to calculate the probability of taking s tag draws to achieve the desired sum.

The height of the building is approximately 86.60 meters.

To find the height of the building, we can use trigonometric ratios, specifically the tangent function.

In this scenario, the angle of elevation is 60 degrees, and the distance from the foot of the building to the point where the angle is measured is 50 meters.

Let's denote the height of the building as 'h'. According to trigonometry, the tangent of an angle is equal to the ratio of the opposite side to the adjacent side.

In this case, the opposite side is the height of the building (h), and the adjacent side is the distance from the foot of the building (50 meters).

Using the tangent function, we have:

tan(60 degrees) = h/50

Simplifying this equation, we can solve for h:

h = 50 × tan(60 degrees)

Using a scientific calculator or trigonometric table, we find that tan(60 degrees) is approximately 1.732.

Therefore, h = 50 × 1.732 ≈ 86.60 meters.

To argue why the liberal arts are so important in education and leisure, one must discuss its Greek origin and how it is received today.

The term "liberal arts" comes from the Latin word "liberalis," which means free. It was used in the Middle Ages to refer to topics that should be studied by free people. Liberal arts refers to courses of study that provide a general education rather than specialized training. It encompasses a wide range of topics, including literature, philosophy, history, language, art, and science.The liberal arts curriculum is based on the idea that a broad education is necessary for individuals to become productive members of society. In ancient Greece, education was focused on developing the mind, body, and spirit.  

The study of the liberal arts is necessary to create well-rounded individuals who can contribute to society in meaningful ways. While the importance of the liberal arts has been debated, it is clear that they are more important now than ever before.

Answer:

x=10

Step-by-step explanation:

according to the question

(x+2)(x-2)=96

=>x^2-4=96

=>x^2=96+4

=>x^2=100

=>x=√100

Therefore

x=10

x=-10

As width and length can't be negative

So x=10

Width=10-2=8

Length=10+2=12

12×8=96 (proven)

Answer:

Please check the explanation.

Step-by-step explanation:

As we know that the area of a rectangle is defined by multiplying the length by the width.

Given

substituting all the given values in the formula to find the value of x.

\(A=l\times w\)

\(96=\left(x+2\right)\times \left(x-2\right)\)

\(96=x^2-4\)

\(x^2-4=96\)

subtract 96 from both sides

\(x^2-4-96=96-96\)

\(x^2-100=0\)

\(x^2=100\)

\(\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\)

\(x=\sqrt{100},\:x=-\sqrt{100}\)

\(x=10,\:x=-10\)

Putting x = -10 in the length and width will make the length and width negative, which can not be possible.

i.e.

length = l = x+2 = -10+2 = -8 units

width = w = x-2 = -10-2 = -12 units

Therefore, x=-10 must be excluded.

Now, putting the length of x = 10.

i.e.

length = l = 10+2 = 10+2 = 12 units

width = w = x-2 = 10-2 = 8

\(A=l\times w\)

96 = 12 × 8

96 = 96

Therefore, the correct value of x = 10
