Guys I need help: In which set of ordered pairs, ( x , y ) , is y NOT a function of x? A. { ( 6 , 6 ) , ( 1 , 1 ) , ( 4 , 4 ) } B. { ( 1 , 4 ) , ( 6 , 4 ) } C. { ( 6 , 1 ) , ( 1 , 6 ) , ( 1 , 4 ) } D. { ( 1 , 4 ) , ( 4 , 1 ) }

Using the concepts of domain and range of functions, we have that:

10. The range is y ≥ 2.

11. The domain is all real numbers, the range is y ≤ 3, and it is a function.

12. The domain is (-4,3], and the range is (-5,5).

Hence, for these problems:

10. The range is y ≥ 2.

11. The domain is all real numbers, the range is y ≤ 3, and it is a function.

12. The domain is (-4,3], and the range is (-5,5).

In item 11, we have that it is a function because it has no vertically aligned points, that is, each value of x is associated with only one value of y.

In item 12, the open intervals are due to the open circles at the extremes of the domain and the range on the graph.

Answer:

Step-by-step explanation:

All the polygons that have four sides are quadrilateral.

Parallelogram is a special type of quadrilateral.

In parallelogram, opposite sides are equal and parallel and opposite angles are equal and the adjacent angles are supplementary.

So, parallelograms are always quadrilateral, as they have four sides

But quadrilateral are only sometimes as it doesn't always have the properties of parallelogram.

yes

Step-by-step explanation:

Answer:

\(\sqrt{73}\)units.

Step-by-step explanation:

We have given a pentagon ABCDE

We need to calculate its length

That means we have to find the distance of AD

So, coordinates of A(1,6) and D(4,-2)

Using distance formula:

Here,

On substituting the values we will get:

On simplification:

Hence, the length of AD is   units.

The matrix A representing the linear transformation T is [5 -2; 0 6].

To find the matrix A that represents a linear transformation T, we need to determine the images of the standard basis vectors under T and use them to form the columns of A. In this case, we are given that T(1,0) = (5,0) and T(0,1) = (-2,6). These correspond to the first and second columns of A, respectively. Therefore, the matrix A is:

A = [5 -2]

[0 6]

To apply T to any vector x, we simply multiply it by A:

T(x) = Ax

So, if we have a vector x = [x1, x2], we can calculate T(x) as follows:

T(x) = [5x1 - 2x2, 6x2]

Thus, A fully characterizes the transformation T and enables the computation of T(x) for any given vector x.

Answer:

Slope = \(-\frac{1}{6}\)

Step-by-step explanation:

Slope = \(\frac{Rise}{Run}\)

Slope = \(\frac{6-10}{24-0}\)

Slope = \(-\frac{1}{6}\)

Answer:

-1/6

Step-by-step explanation:

Just use the formula Y2-Y1/X2-X1.

In this case if you substitute the coordinates of those numbers, then it would be 6-10/24-0 which is 24/-4 and if you simplify it, then you get the slope -1/6.

Answer:

x = number of wheelbarrow = 40

y = number of wagon = 30

Step-by-step explanation:

Let

x = number of wheelbarrow

y = number of wagon

x + y = 70 (1)

x + 4y = 160 (2)

subtract (1) from (2) to eliminate variable x

4y - y = 160 - 70

3y = 90

y = 90/3

y =30

Substitute y = 30 into (1)

x + y = 70 (1)

x + 30 = 70

x = 70 - 30

x = 40

x = number of wheelbarrow = 40

y = number of wagon = 30

The two triangles \(\triangle HGF\) and \(\triangle ABC\) given in figure are not similar.

Two triangles are said to be similar when their three pairs of corresponding sides are equal. And also if two triangles have all congruent angles, all proportional sides then triangles are similar.

We have,

\(\triangle HGF\) and \(\triangle ABC\) neither they have congruent angles nor they have equal sides and also they do not have all proportional sides.

So, from the above given statement of similarity in triangles, we can conclude that both the given triangles \(\triangle HGF\) and \(\triangle ABC\) are not similar.

Other factors like temperature, air density, and humidity can affect the ball's flight. For instance, denser air, often associated with colder temperatures, can impede the ball's movement and reduce its travel distance.

In addition to the angle of elevation, several other determining factors come into play when determining whether a hit ball will clear the center field fence. Two significant factors to consider are the initial velocity of the ball and the atmospheric conditions.

The initial velocity of the ball strongly influences its trajectory and distance. A higher initial velocity will result in a longer travel distance, increasing the chances of clearing the fence. However, if the ball is not hit with enough velocity, it may not have the necessary power to surpass the fence height.

Atmospheric conditions, including wind speed and direction, can greatly impact the ball's flight path. A strong tailwind can provide additional lift and carry to the ball, aiding its trajectory and helping it clear the fence. Conversely, a headwind can have the opposite effect, causing the ball to lose speed and distance, potentially falling short of the fence.

Furthermore, other factors like temperature, air density, and humidity can affect the ball's flight. For instance, denser air, often associated with colder temperatures, can impede the ball's movement and reduce its travel distance.

Considering these factors along with the angle of elevation provides a more comprehensive understanding of whether a hit ball will clear the center field fence. Each factor interacts and contributes to the ball's final destination, making baseball a game where multiple variables must be accounted for to achieve success.

]The amount to pay is £921.375

The loan's interest rate can be quickly and easily calculated using simple interest. The daily interest rate is multiplied by the principal by the number of days between payments to get simple interest.

Given cash price of a television = £ 875

and deposit money is 10%

so 10% of 875 = 87.5

the principle of television = 875 - 87.5 = 787.5

and rate = 8.5%, time = 2 years

simple interest is give by (P x R x T)/100

SI  = (787.5 x 8.5 x 2)/100 = 133.875

total amount o be paid = principle + SI

A =  787.5 + 133.875

A = 921.375

Answer:

this doesn't make any sense.

The blueberry muffins made by baker on monday is 40% of the total muffins made by the baker .

A quantity or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. In order to determine the percentage of a number, divide it by its sum and then multiply the result by 100. The proportion thus refers to a component per 100. The word percent indicates a percentage of 100. The word "percent" denotes "per 100." The letter "%" stands for it.

Now in the given question,

Total number of muffins baker made = 90

Blueberry Muffins made by baker on monday = 36

Prcentage of blueberry muffins out of total muffins  \(=\frac{36*100}{90} = 40 %\)

Answer:

26.6667

Step-by-step explanation:

.15x=100

Divide each side by .15.

x=666.6667

.04(666.6667)=26.6667

Answer:

26(approx.)

Step-by-step explanation:

15/100 times x = 100

3/20 times x = 100

3x/20 = 100

3x = 2000

X= 666 2/3

So,

4/100 x 666.67

1/25 x 666.67 = 26

*I included both possibilities since I didn't see a picture of the way in which the semicircle and rectangle were joined.*

Step-by-step explanation:

In order to solve, you have to know the formula for area of a circle which is A=πr^2 (pi*radius to the 2nd power)

The problem does not give us the radius, but we know that radius is half of the diameter.

To find the diameter, we have to use the side measurement of the rectangle and divide it by 2 to find the radius.

Next, we increase the radius to the 2nd power, giving us the radius of a whole circle.

Finally, we have to divide that by 2 since it's a semi circle otherwise known as half of a circle.

I put the answer in terms of pi since that's the most accurate, but if the question specifically instructs it, you can calculate part of the irrational decimal and round to a certain place value.
