Therefore, both sequence A and sequence B can be used to map EFGH onto ABCD, so the answer is C) Both.

In mathematics, a transformation is a process of changing the position, size, or shape of a geometric figure. Transformations can be performed on two-dimensional or three-dimensional objects and include operations such as translation, rotation, reflection, scaling, and shearing. Translation involves moving an object in a straight line without rotating it. Rotation involves turning an object around a fixed point. Reflection involves flipping an object across a line or plane of symmetry. Scaling involves changing the size of an object, making it larger or smaller. Shearing involves distorting an object by pushing or pulling one of its sides. Transformations are often used in geometry and in other areas of mathematics and science to explore the properties of objects and to solve problems related to symmetry, similarity, and congruence. They are also used in computer graphics, animation, and other areas of computer science to create and manipulate images.

Here,

Both sequences of transformations can be used to map quadrilateral EFGH onto ABCD.

To see why, consider that a -90⁰ rotation about point H followed by a translation along HD will map H to A, E to D, F to C, and G to B. Similarly, a -90⁰ rotation about point F followed by a translation along FA will map F to A, G to D, H to C, and E to B.

Answer:

  (A)  Only sequence A

Step-by-step explanation:

You want the sequence of transformations that maps parallelogram EFGH to ABCD.

We note that segment EF points to the right, and corresponding segment AB points down. The rotation required to change the direction in that way is a rotation of -90°, that is, 90° CW.

The translation that will work in this context is translation of the center of rotation to its corresponding point on the image. The given choices of center are ...

Point H corresponds to point D, so the translation vector would need to be HD after rotation about point H. This matches sequence A.

Point F corresponds to point B, so the translation vector would need to be FB after rotation about point F. Sequence B erroneously has the vector as FA.

Only sequence A maps EFGH to ABCD, choice A.

The equation that represents the perimeter of the rectangle is:

\(\text{Perimeter} = \frac{2}{3} \times [4l-27]\)

Step-by-step explanation:

The perimeter of a rectangle is given by the formula:

Perimeter = 2 × [l + w]

It is provided that the width of a rectangle is 9 less than one-third it's length.

That is:

\(w = \frac{1}{3}l-9\)

The perimeter is given as 45.

The equation that represents the perimeter of the rectangle is:

\(\text{Perimeter} = 2 \times [l + \frac{1}{3}l-9]\\\\\text{Perimeter} = 2 \times [\frac{3l+l-27}{3}]\\\\\text{Perimeter} = 2 \times [\frac{4l-27}{3}]\\\\\text{Perimeter} = \frac{2}{3} \times [4l-27]\)

Thus, the equation that represents the perimeter of the rectangle is:

\(\text{Perimeter} = \frac{2}{3} \times [4l-27]\)

A total of 8 workers are required for a building time of 15 days.

In this problem we find a case of inverse relationship, in which the number of workers (n) is inversely proportional to building time (t), in hours. The situation is represented by following formulas:

n ∝ 1 / t

n = k / t

Where k is the proportionality ratio, which can be eliminated by building the following formula:

n₁ · t₁ = n₂ · t₂

If we know that n₁ = 10, t₁ = 12 and t₂ = 15, then the required number of workers is:

n₂ = n₁ · (t₁ / t₂)

Step-by-step explanation: The straight line or line X is 180 degrees. So subtracted 20. This is because X is intersected by another line which makes the upper notch 20 degrees.

The table can be summarized as follows:

|          | Has a dog | Does not have a dog |

|----------|-----------|---------------------|

| Has a cat     | 2         | 3                   |

| Does not have a cat | 12        | 10                  |

To find the probability that a student chosen randomly from the class has a cat, we need to find the total number of students who have a cat (regardless of whether or not they have a dog), and divide it by the total number of students in the class.

The number of students who have a cat is 2 (those who have a dog and a cat) + 3 (those who have a cat but do not have a dog) = 5.

The total number of students in the class is the sum of all four categories: 2 (has a cat and a dog) + 3 (has a cat, does not have a dog) + 12 (does not have a cat, has a dog) + 10 (does not have a cat, does not have a dog) = 27.

So, the probability that a student chosen randomly from the class has a cat is 5/27.

The three options that represent the correct steps to solve quadratic equation are:

What is equation?

In mathematics, an equation is a statement that two expressions are equal. It typically consists of two sides, called the left-hand side (LHS) and the right-hand side (RHS), connected by an equal sign.

To solve the quadratic equation \(8x^2 + 16x + 3 = 0\), Patel could use the following steps:

Use the quadratic formula: x = (-b ± √(\(b^2\) - 4ac)) / 2a, where a = 8, b = 16, and c = 3. This formula gives the solutions to any quadratic equation of the form \(ax^2\) + bx + c = 0.

Factor the quadratic equation by finding two numbers that multiply to give ac (8 * 3 = 24) and add to give b (16).

This can be a bit tricky, but in this case, the factors are (4, 6). So we can write \(8x^2\) + 16x + 3 as \(8x^2\) + 4x + 2x + 3, and then group the terms as (\(8x^2\) + 4x) + (2x + 3) = 4x(2x + 1) + 1(2x + 3).

Use the factored form of the equation to set each factor equal to zero and solve for x.

So we have 4x(2x + 1) + 1(2x + 3) = 0, which gives us two possible solutions: 2x + 1 = 0, which gives x = -1/2, and 2x + 3 = 0, which gives x = -3/2.

The dimensions of the pen are 93 yds by 27 yds.

Clark's Country Pet Resort has to fence a new play area for dogs. The manager has purchased 240 yd of fence to enclose a rectangular pen, and the area of the pen must be 2511 yd². We need to calculate the dimensions of the pen.

In order to find the dimensions of the pen, we will use the following formula: Area of rectangle = length × width given that, area of the pen = 2511 yd²Let us assume the length of the pen as 'l' and the width of the pen as 'w'.

Then, the area of the rectangle will be: A = l × wBut, the area of the pen is 2511 yd²Therefore,2511 = l × wNow, we need to find the length and width of the rectangular pen using the given perimeter.

Let's represent the perimeter of the pen as 'P'.The formula for the perimeter of a rectangle is:P = 2(l + w)Given that, the perimeter of the pen = 240 yd240 = 2(l + w)120 = l + We can now use substitution in order to solve for the dimensions of the pen.

We know that l + w = 120Therefore, l = 120 - wow, we can use the formula for the area of the pen.2511 = l × w2511 = (120 - w) × w2511 = 120w - w²w² - 120w + 2511 = 0Now, we can solve for 'w' using the quadratic formula: w = (-b ± √(b² - 4ac)) / 2aPutting the values of a, b, and c in the above formula we get,w = (-(-120) ± √((-120)² - 4×1×2511)) / 2×1w = (120 ± √(14400 - 10044)) / 2w = (120 ± √4356) / 2w = (120 ± 66) / 2w = 93 or 27Since the width cannot be 93 (it is too long for the area and perimeter), we will consider the width as 27. Now, we can solve for the length.120 = l + 27120 = l + 27l = 120 - 27l = 93

Answer:

There is not sufficient evidence to support the claim that the technique performs differently than the traditional method.

Step-by-step explanation:

The null hypothesis is:

\(H_{0} = 95\)

The alternate hypotesis is:

\(H_{1} \neq 95\)

The test statistic is:

\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)

In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, \(\sigma\) is the standard deviation and n is the size of the sample.

A researcher used the technique with 260 students and observed that they had a mean of 94 hours. Assume the standard deviation is known to be 6.

This means, respectively, that \(n = 260, X = 94, \sigma = 6\)

The test-statistic is:

\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)

\(z = \frac{94 - 95}{\frac{6}{\sqrt{260}}}\)

\(z = -2.69\)

The pvalue is:

2(P(Z < -2.69))

P(Z < -2.69) is the pvalue of Z when X = -2.69, which looking at the z-table, is 0.0036

2*(0.0036) = 0.0072

0.0072 < 0.01, which means that the null hypothesis is accepted, that is, there is not sufficient evidence to support the claim that the technique performs differently than the traditional method.

The equation of the line that is parallel to the line whose equation is 3x-2y=7 would be y = 3/2x + b, in which b can be any real number.

How are parallel straight lines related?

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

We have been given a parallel line with has equation

3x-2y=7

In order to solve this, the slope of the original line.

3x - 2y = 7

-2y = -3x + 7

y = 3/2x - 7/2

thus its slope is 3/2.

thus, the slope of the needed line is 3/2 too.

we know that any line that is parallel to that would have this slope.

So anything is written in the form:

Answer:

the value of a - b is 4.

Step-by-step explanation:

We have been given the following two equations:

a + b = 10 ------------(1)

a² - b² = 40 -------(2)

We can factor the left-hand side of equation (2) using the difference of squares identity:

(a + b)(a - b) = 40

Substituting equation (1) into this equation, we get:

10(a - b) = 40

Dividing both sides by 10, we get:

a - b = 4

Therefore, the value of a - b is 4.

Step-by-step explanation:

if I understand this correctly :

a + b = 10

a² - b² = 40

(a² - b²) = (a + b)(a - b) = 40

10(a - b) = 40
