Answer:

x = 27°, ∠JLK = 55°

Step-by-step explanation:

From the diagram in the question above,

The exterior angle of a triangle is equal to the sum of the two opposite side

3x+13 = 39+(2x+1)

3x+13 = 40+2x

collect like terms and solve for x

3x-2x = 40-13

x = 27°.

∠JKL = 2x+1

Substitute the value of x

∠JKL = 2(27)+1

∠JKL = 54+1

∠JKL = 55°

Hello!

90 + 45%

= 90 * 1.45

= 130.5

The correct answer of the operation is option B: 4x^2 - 9.

To perform the operation (2x-3)(2x+3), we can use the FOIL method, which stands for First, Outer, Inner, Last. Let's go through the steps:

First: Multiply the first terms of each binomial.

(2x)(2x) = 4x^2

Outer: Multiply the outer terms of each binomial.

(2x)(3) = 6x

Inner: Multiply the inner terms of each binomial.

(-3)(2x) = -6x

Last: Multiply the last terms of each binomial.

(-3)(3) = -9

A binomial is a two-term algebraic expression that contains variable, coefficient, exponents and constant, a binomial is an expression that has two unlike terms connected through an addition or subtraction operator in between.  

Now, let's combine the like terms:

4x^2 + 6x - 6x - 9

Notice that the terms 6x and -6x cancel each other out.

Simplifying further, we have:

4x^2 - 9

The correct answer is option B: 4x^2 - 9.

Answer:

{11}

Step-by-step explanation:

We are given the following equation:

25 - 7x = -52

And we want to solve and check the solution.

In order to solve this, we want to isolate the variable so that it is only on one side.

To start, subtract 25 from both sides.

25 - 7x = -52

-25          -25

________________

-7x = -77

Now, even though we have the variables on one side and and the numbers on the other, we aren't done yet.

Divide both sides by -7.

-7x = -77

÷-7    ÷-7

________________

x = 11

Now, we should check the solution to make sure it works.

Substitute 11 for x in 25-7x = -52.

25 -7(11) = -52

25 - 77 = -52

-52 = -52

This is a true statement, so the solution works.

The answer is x = 11, or written as a set, {11}.

No, the given relation is not a function. An association between items of two sets—the domain and the codomain—is known as a binary relation.

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

A binary connection in mathematics links elements of one set, referred to as the domain, with elements of another set, referred to as the codomain. A new set of ordered pairs made up of elements from sets X and Y and x in X is known as a binary relation across these sets.

Al-Biruni and Sharaf al-Din al-Tusi, two Persian mathematicians, are responsible for the earliest documented treatment of the concept of function. Initially, functions represented the idealised relationship between two changing quantities.

Consider the given relation

{(0.3, 0.6), (0.4, 0.8), (0.3, 0.7), (0.5, 0.5)}

We need to check whether the given relation is function or not.

A relation is a function if there exist a unique value of y for each value of x.

In the given relation, for x=0.3 there exist more than one value of y.

y=0.6 at x=0.3

Answer:

The value of x if the scale factor of figure A to figure B is 4:5 is; x = 12

We are given the scale factor of figure A to figure B as 4:5.

By use of similar triangles theorem, we can deduce that the ratio of corresponding sides of figure A to corresponding sides of figure B must be equal to 4:5.

Now, looking at both triangles, we can say that;

x:15 = 4:5

Thus,we can write in fraction as;

x/15 = 4/5

x = 15 × 4/5

x = 12

In conclusion, the value of x from the given proportion between both triangles is 12.

The volume generated when the plane figure bounded by the curve y = x² + 5, the x-axis, and the ordinates x = 1 and x = 3 rotates about the y-axis through a complete revolution can be found using the method of cylindrical shells.

The volume can be calculated by integrating the formula V = 2π ∫[a,b] x f(x) dx, where a and b are the x-values of the bounds of the region, and f(x) represents the distance from the axis of rotation to the curve at each x-value.

In this case, the curve y = x² + 5 intersects the x-axis at y = 0 when x = ±√5i. We are given the bounds of x = 1 and x = 3, which lie entirely above the x-axis. Therefore, the volume can be obtained by integrating the formula V = 2π ∫[1,3] x (x² + 5) dx.

Evaluating this integral, we get V = 2π ∫[1,3] (x³ + 5x) dx = 2π [(1/4)x⁴ + (5/2)x²] evaluated from 1 to 3. Simplifying further, we have V = 2π [(81/4 + 45/2) - (1/4 + 5/2)] = 2π (99/4 - 3/4) = 96π/4 = 24π.

Therefore, the volume generated when the given figure rotates about the y-axis through a complete revolution is 24π cubic units.

If Abby is collecting rainfall data, and she finds that one value of the data set is a high-value outlier, then the statement that must be true is "the outlier will pull the mean towards its value."

Outliers are the data points in a distribution that stand out from the rest. In other words, an outlier is a value that is far from the other values in the dataset.

An outlier is a value that is more than 1.5 times the interquartile range (IQR) greater than the upper quartile or less than the lower quartile plus 1.5 times the IQR, which is often referred to as the "1.5*IQR rule."

Here are a few statements that describe the impact of an outlier on a data set:

An outlier does not have an effect on the median value of the data set.

The presence of an outlier in a dataset will raise the range of the dataset.

The presence of an outlier in a dataset will raise the standard deviation of the dataset.

The outlier will pull the mean towards its value, as well as increase the value of the mean.

With the usage of isometric dot paper, we can sketch as per the attached image.

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The triangular prism has 5 faces and 6 vertices.

Now given the prism is 2 units high, with bases that are right triangles with legs 3 units and 4 units long.

The steps will be as follows,

⇒ Let's make the corner of the solid. Draw 2 units down, 4 units to the right, and 5 units to the left. And draw the triangle.

Answer:

PM = 58

Step-by-step explanation:

The question tells us that the full line has a value of 6x+56. The midpoint divides this line into equal pieces. We are also given the value of half (MQ) of the line (5x+8). By subtracting 5x+8 from 6x+56, we can figure out the value of the other half of the line (PM).

This gives us the expression for PM: x+48

Now, since these are both the two parts of the midpoint, by definition, we know they're equal.

You equal both equations and get x=10

You plug in 10 as x in the expression we got for PM (10+48), which gives us the value 58.

The length of the rectangle is 46 meters, and the width is also 46 meters.

Let's start with the formula for the perimeter of a rectangle:

Perimeter = 2 x (length + width)

We know that the perimeter is 184 meters, so we can plug that in:

184 = 2 x (length + width)

Simplifying the equation, we get:

92 = length + width

To maximize the area, we need to find the dimensions that satisfy this equation and also maximize the area formula:

Area = length x width

We can use substitution to express the area in terms of one variable:

Area = length x (92 - length)

Now we have a quadratic equation that we can optimize using the vertex formula:

The x-value of the vertex of the parabola

\(y = ax^2 + bx + c\) is given by -b/2a. In this case, a = -1 and b = 92.

The x-value of the vertex is -92/(-2) = 46.

The coefficient of the \(x^2\) term is negative, the parabola is concave down and the vertex represents the maximum value of y.

The maximum area occurs when the length is 46 meters, and the width is:

width = 92 - length

width = 92 - 46

width = 46 meters

The height of the arch at its center is 41 meters. A sketch of the arch labeled is shown below: (please note that this is not to scale)

To find the height of the arch at its center, let's assume that the semi-elliptical arch's equation is represented by a general formula:

y^2/a^2 + x^2/b^2 = 1

where y represents the height of the arch at any given point, a is the semi-major axis, and b is the semi-minor axis.

To find a, we'll need to divide the span of the bridge by two. Therefore, the semi-major axis,

a = 164/2 = 82 meters.

We can determine b, the semi-minor axis, by substituting the height of the arch, 9 meters, when x = 80 meters.

\(9^2/82^2 + 80^2/b^2 = 1\)

Solving for b, we get :

b = \(82(1 - 9^2/82^2 * 80^2)^1/2b = 45.6\) meters

Finally, we can find the height of the arch at its center by plugging in x = 0 (the center) into the formula:

\(9^2/82^2 + 0^2/45.6^2 = 1\)

Simplifying, we get:

81/6724 + 0 = 1.

Solving for y, we get:

y = \(82(1 - 6724/81)^1/2y\) = 41 meters .

Therefore, the height of the arch at its center is 41 meters. A sketch of the arch labeled is shown below: (please note that this is not to scale).

The multiplicity of a root r of the characteristic equation of A is called the algebraic multiplicity of r as an eigenvalue of A.

The above statement is True.

Eigenvalue:

An eigenvalue is a special set of scalar values ​​associated with the most probable system of linear equations in a matrix equation. Eigenvectors are also called eigenvalues. It is a non-zero vector which can be modified by at most its scalar factor after applying a linear transformation.

According to the Question:

If the geometric multiple of the eigenvalues ​​is greater than or equal to 2, the linearly independent set of eigenvectors is no longer unique to the multiple as before. For example, for the diagonal matrix A=[3003], one could also choose the eigenvectors [11] and [1−1], or any pair of two linearly independent vectors.

Sometimes vectors are simply expanded to vector times matrix. If this happens, this vector is called the eigenvector of the matrix and the "stretch factor" is called the eigenvalue. Example: Given a square matrix A, λ is the eigenvalue of A, and the corresponding eigenvector x is
