What the spare root of 27

The following 2-dimensional transformations can be represented as matrices:

a. Rotation

c. Translation

d. Reflection

Rotation, translation, and reflection transformations can all be represented using matrices. Rotation matrices represent rotations around a specific point or the origin. Translation matrices represent translations in the x and y directions. Reflection matrices represent reflections across a line or axis.

Magnification, on the other hand, is not represented by a single matrix but involves scaling the coordinates of the points. Therefore, magnification is not represented directly as a matrix transformation.

So the correct options are:

a. Rotation

c. Translation

d. Reflection

Answer:

Step-by-step explanation:

So we can define decreasing x% in two ways: we can define 20% off as 80% of the original value, or we can define subtracting 20% from the original value, and both representations are useful.

In this case it's more useful to define 20% as subtracting 20%, from the original value. The reason for this, is because since we're subtracting 20% of the original value, we then know that 126.40 is 20% the original value.

So to find x% of some value, you generally use the following equation: \(A*\frac{x}{100}\) where A=original amount, and x is the percent. This equation is simply converting the x% to a decimal value. Since 126.40 is 20%, we can derive the following equation.

\(0.20A = 126.40\)

We can solve for A, by dividing by 0.20

\(A=632\\\)

It's also important to note, you didn't really have to set up this entire equation, since you know that the 126.40 is 20%, you simply could've multiplied by 5, since 20% is really just 1/5 of the entire value, so get the entire value, or original value you multiply by 5

The air speed of a small airplane during the first 25 seconds of takeoff and flight can be modeled by Newton's Second Law of Motion.

According to Newton's Second Law of Motion, the rate of change of the airplane's momentum is equal to the sum of all the forces acting on the airplane. As the plane takes off and accelerates, the thrust of the engines acting in the forward direction causes the plane's momentum to increase. This increase in momentum results in an increase in air speed. The air resistance acting against the motion of the plane is another force that affects the plane's speed. As the plane accelerates, the air resistance increases, and the plane's speed decreases.

In summary, the air speed of a small airplane during the first 25 seconds of takeoff and flight can be modeled by Newton's Second Law of Motion, where the thrust of the engines and air resistance act as forces that influence the plane's air speed.

The relation of equipotence is an equivalence relation on the collection 2x of all subsets of set x. The equivalence class of a set, under this relation, represents the cardinality of the set, which is a measure of its size or the number of elements it contains.

The relation of equipotence is an **equivalence relation** on the collection 2x, which represents all subsets of set x. The equivalence class of a set, with respect to the relation of equipotence, is known as the **cardinality** of the set.

An equivalence relation is a relation on a set that satisfies three properties: reflexivity, symmetry, and transitivity. Let's explore how the relation of equipotence satisfies these properties.

1. Reflexivity: For any set A in 2x, A is equipotent to itself. In other words, any set is equivalent to itself in terms of its cardinality. This satisfies the reflexivity property of an equivalence relation.

2. Symmetry: If set A is equipotent to set B, then set B is equipotent to set A. The notion of equipotence does not depend on the order or arrangement of elements within sets. So, if A has the same cardinality as B, then B also has the same cardinality as A. This satisfies the symmetry property.

3. Transitivity: If set A is equipotent to set B, and set B is equipotent to set C, then set A is equipotent to set C. If two sets have the same cardinality and one of them has the same cardinality as a third set, then the first set is also equipotent to the third set. This satisfies the transitivity property.

As a result, the relation of equipotence on 2x fulfills all the requirements of an equivalence relation. Each equivalence class, or set of sets, formed by this relation represents the sets that share the same cardinality.

The cardinality of a set is essentially a measure of the "size" or "number of elements" in that set. It is represented by a non-negative integer. For example, if set A has three elements, its cardinality is 3. The equivalence class of set A, with respect to the relation of equipotence, would consist of all sets that have the same cardinality as A, that is, all sets with three elements.

In summary, the relation of equipotence is an equivalence relation on the collection 2x of all subsets of set x. The equivalence class of a set, under this relation, represents the cardinality of the set, which is a measure of its size or the number of elements it contains.

Answer: To solve for A in the equation -BA + g² = MA, we can start by isolating the A variable on one side of the equation.

We can start by adding BA to both sides of the equation:

-BA + BA + g² = MA + BA

Simplifying the left side by cancelling the -BA and +BA terms:

g² = MA + BA

Next, we can factor out the A variable from the right side:

g² = A(M + B)

Finally, we can divide both sides by (M + B) to isolate the A variable:

g² / (M + B) = A

So the solution for A is:

A = g² / (M + B)

The box has volume

11 in × 3 in × x in = 33x in³

and surface area

2 (11 in × 3 in + 11 in × x in + 3 in × x in) = (66 + 28x) in²

The volume and area have the same value if

33x = 66 + 28x

Solve this equation for x :

33x - 28x = 66

5x = 66

x = 66/5 = 13.2

The equivalent expression is (7/4)² x (2/3)³

Option B is the correct answer.

Given,

[(4/7)^2 x (2/3)^-3]^-1

We need to see which option is correct.

Here the exponents are the power of a given number where the power is an integer.

Example:

3^a

where a can be -1,-2,-4,-5, 3, 4, 5.

(1/3)^-a = 1^-a / 3^-a = 1 / 3^-a = 1/ (1/3^a) = 3^a

We have,

[(4/7)^2 x (2/3)^-3]^-1

Removing the second bracket.

(4/7)^(2x-1) x (2/3)^-3x(-1)

(4/7)^-2 x (2/3)^3

We can write,

(4/7)^-2

= 1/(4/7)^2

= (7/4)^2

(4/7)^-2 x (2/3)^3

= (7/4)^2 x (2/3)^3

Thus the equivalent expression is (7/4)² x (2/3)³

Option B is the correct answer.

The missing terms of the sequence are 15.75 and 7.875, and the sequence is geometric.

What is sequence?

In mathematics, a sequence is an ordered list of numbers or objects in a specific pattern or order. Each individual element in the sequence is called a term or member of the sequence.

To determine the missing terms of the sequence and determine its pattern (whether arithmetic, geometric, or neither), let's examine the given sequence: 252, 126, 63, 63/2, __, __.

First, let's check if the sequence has a common difference between consecutive terms to determine if it is an arithmetic sequence. We'll calculate the differences between consecutive terms:

Difference between the 2nd and 1st terms: 126 - 252 = -126

Difference between the 3rd and 2nd terms: 63 - 126 = -63

Difference between the 4th and 3rd terms: (63/2) - 63 = -63/2

The differences are not constant, so the sequence is not arithmetic.

Next, let's check if the sequence has a common ratio between consecutive terms to determine if it is a geometric sequence. We'll calculate the ratios between consecutive terms:

Ratio between the 2nd and 1st terms: 126/252 = 1/2

Ratio between the 3rd and 2nd terms: 63/126 = 1/2

Ratio between the 4th and 3rd terms: (63/2) / 63 = 1/2

The ratios are constant (1/2), so the sequence is geometric.

Since the sequence is geometric with a common ratio of 1/2, we can use this ratio to find the missing terms.

To find the next term, we multiply the previous term by the common ratio:

(63/2) * (1/2) = 63/4 = 15.75

To find the term after that, we multiply the previous term by the common ratio again:

(63/4) * (1/2) = 63/8 = 7.875

Therefore, the missing terms of the sequence are 15.75 and 7.875.

In summary, the missing terms of the sequence are 15.75 and 7.875, and the sequence is geometric.
