Which of the following graphs shows a dilation of the triangle from a fixed point?

Answer:

2

Step-by-step explanation:

any expression divided by 1 remains the same

you can also calculate the factorial

Step-by-step explanation:

In order to find the answer, we need to, find the denominator. The least common denominator would be 6 for 1 1/2 + 2 1/3, so if you would do it on paper, the equation would look like this, 1 3/6 + 2 2/6. Now that we have the same common denominator, we can add the fractions together. First we add the wholes, 1+2 = 3, and then, 3/6 + 2/6 which would be 5/6. Then combine you're answer together, and you would get 3 5/6 as your final answer.

Matrix addition can only be performed on matrices of the same size.

This means that you can only add matrices if both matrices are m × n.

For example, you can add two or more 3 × 3, 1 × 2, or 5 × 4 matrices. You cannot add a 2 × 3 and a 3 × 2 matrix, a 4 × 4 and a 3 × 3, etc.

The number of rows and columns of all the matrices being added must exactly match.

Therefore, the answer is letter D - These two matrices cannot be added.

Answer:

38 people

Step-by-step explanation:

In this case, we can see that, being two people, the cost is 14 and when it is double, that is, 4 people, the value is not 28 but 20.

Which means that there is an additional value that is being charged for the vehicle, that is:

let "c" be the value of the vehicle and "x" be the value per person

c + 2 * x = 14

c + 4 * x = 20 => c = 20 - 4 * x

replacing:

20 - 4 * x + 2 * x = 14

-2 * x = 14-20

-2 * x = -6

x = 6/2

x = 3

for C:

c = 20 - 4 * 3

c = 8

Which means that the formula for the value of the input would then be:

e = 8 + 3 * n

where "n" is the number of people.

Now, we are told that for e = 122

122 = 8 * + 3 * n

3 * n = 122 -8

n = 114/3

n = 38

which means that for that bus there are a total of 38 people

1. The distance all the way across the cooker. In this case, 136 cm.

1. The coordinates of the edges of the cooker can be determined by considering the distance from the vertex to the edge of the cooker. Given that the distance from the vertex to the edge is 68 cm, and the vertex is at (-32, 0), we can find the coordinates of the edges as follows:

One edge of the cooker: (-32 + 68, 0) = (36, 0)

The other edge of the cooker: (-32 - 68, 0) = (-100, 0)

The distance all the way across the cooker. In this case, it is 36 - (-100) = 136 cm.

2. To write an equation for the parabolic mirror, we can use the standard form of a parabolic equation, which is y = a(x - h)² + k, where (h, k) represents the vertex of the parabola.

In this case, the vertex is at (-32, 0).

The equation becomes y = a(x + 32)² + 0.

Substituting these coordinates into the equation, we get:

0 = a(36 + 32)² + 0

0 = a(68)²

0 = 4624a

From this, we can see that a = 0, which means the equation simplifies to y = 0, indicating that the parabolic mirror is a straight line along the x-axis.

The player made 38 foul shots.

Let's indicate the player's total number of field goals made by F and foul shots attempted by S. Based on the data in the problem, we may construct an equation system:

F + S = 55 (the player made a total of 55 baskets) (the player made a total of 55 baskets)

2F + S = 89 (the player scored a total of 89 points) (the player scored a total of 89 points)

The substitution approach can be used to find the values of F and S. We start by resolving the initial S equation:

S = 55 - F

Next, we change S in the second equation to the following expression:

2F + (55 - F) = 89

When we simplify and find F, we obtain:

F = 17

Hence, the player connected on 17 field goals. We may change this value of F into the first equation and then solve for S to determine the total number of foul shots:

17 + S = 55

S = 38

The player so scored 38 fouls.

Answer:

2x - 3 = 11

x = -21

Step-by-step explanation:

The linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

To determine the linear function with the same y-intercept as the graph, we need to find the equation of the line passing through the points (3, 4) and (5, 0).

First, let's find the slope of the line using the formula:

slope (m) = (change in y) / (change in x)

m = (0 - 4) / (5 - 3)

m = -4 / 2

m = -2

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Using the point (3, 4) as our reference point, we have:

y - 4 = -2(x - 3)

Expanding the equation:

y - 4 = -2x + 6

Simplifying:

y = -2x + 10

Now, let's check the given options to find the linear function with the same y-intercept:

Option 1: The table with x-values (-3, -1, 1, 3) and y-values (-4, 2, 8, 14)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 2: The table with x-values (-4, -2, 2, 4) and y-values (-26, -18, -2, 6)

The y-intercept is not the same as the given line. So, this option is not correct.

Option 3: The table with x-values (-5, -3, 3, 5) and y-values (-15, -11, 1, 5)

The y-intercept is the same as the given line (10). So, this option is correct.

Option 4: The table with x-values (-6, -4, 4, 6) and y-values (-26, -14, 34, 46)

The y-intercept is not the same as the given line. So, this option is not correct.

Therefore, the linear function that has the same y-intercept as the given graph is the equation y = -2x + 10, corresponding to option 3.

Answer:

X²(4+x)

Step-by-step explanation:

You pick out the common term

Greetings.

The answer is x²(4+x)

Explanation:

\(4x^2+x^3\\\)

By using a common factor, we factor x-term out. We factor the x-term with least degree and that is 2-degree. So we factor x² out.

When factored out, It's similar to dividing. When x² is divided by itself, the result is 1. When x³ is divided by x², the result is x (From the property of exponent.)

Similar to dividing, but we pull x² out.

\(4x^2+x^3\\x^2(4+x)\)

Therefore, the answer/factored form is x²(4+x)

Answer:

4 kilometers is equal to 4000 meters.

Step-by-step explanation:

1 kilometer is equal to 1000 meters, so 4 kilometers is equal to 4 x 1000 = 4000 meters. This is because the prefix "kilo" means 1000, so 1 kilometer is equivalent to 1000 meters.

Answer:

y = (x - 4)²

Step-by-step explanation:

the parent function y = x² has its vertex at (0, 0 )

the graph of y = (x - 4)² is the graph of y = x² translated horizontally by 4 units.

• a shift of 4 units is a shift to the left

• a shift 0f - 4 units is a shift to the right

Then

a vertex at (4, 0 ) has equation y = (x - 4)²

The actual distance represented by 1 centimetre is 0.16 kilometres.

Given that, the scale on a map is 1:16000.

We need to find what is the actual distance represented by 1 centimetre.

A scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size.

Now, the scale on a map is 1:16000.

That is 1 centimeter in map = 16000 actual centimeters.

1 meter = 100 centimeters.

1 kilometer = 1000 meter.

So, 1 kilometer = 100000 centimeters.

Now, the actual distance=16000/100000=0.16 km

Therefore, the actual distance is 0.16 km.

The Central tendency is typically located to the right of the tallest bar.

In a skewed left distribution, the central tendency is typically located to the right of the tallest bar. Skewed left distributions, also known as negatively skewed distributions, are characterized by a tail that extends towards the left side of the distribution.

The central tendency refers to the measure that represents the center or average of a distribution. It provides information about the typical or central value around which the data points tend to cluster. Common measures of central tendency include the mean, median, and mode.

In a skewed left distribution, the mean is usually influenced by the long tail on the left side of the distribution. This tail pulls the mean towards lower values, resulting in a lower mean compared to the median. Therefore, the mean will typically be located to the left of the tallest bar in a skewed left distribution.

On the other hand, the median is less affected by the skewness of the distribution and is relatively robust to extreme values. It represents the value that separates the lower 50% of the data from the upper 50%. In a skewed left distribution, the median will be located closer to the tallest bar or even slightly to the right of it.

The mode, which represents the most frequently occurring value in a distribution, may or may not be influenced by the skewness depending on the shape of the distribution. It can be located anywhere along the distribution, and its position is not necessarily tied to the location of the tallest bar.

To summarize, in a skewed left distribution, the central tendency is typically located to the right of the tallest bar. The median is usually closer to the tallest bar or slightly to the right, while the mean is influenced by the skewness and tends to be located to the left of the tallest bar.
