Therefore, the value of x is 26.

in geometry, an angle is a measure of the amount of rotation between two intersecting lines, or between a line and a plane. It is typically measured in degrees, with a full rotation equal to 360 degrees. Angles can also be measured in radians, which is another unit of angular measurement .Since ∠1 and ∠2 are supplementary, their sum is equal to 180 degrees. That is:

m∠1 + m∠2 = 180

Substituting the given values, we have:

124° + (2x+4)° = 180°

Simplifying this equation, we get:

2x + 128 = 180

Subtracting 128 from both sides, we have:

2x = 52

Dividing both sides by 2, we get:

x = 26

To graph the function, we can start by plotting a few key points. The first point is (0, 2), since F(0) = cos(0) + 1 = 2. The next point is (1, 1), since F(1) = cos(pi/2) + 1 = 1. We can continue this pattern by adding 1 to the x-value and finding the corresponding y-value.
x F(x)

0 2

1 1

2 0

3 1

4 2

5 1

6 0

Using these points, we can plot the graph of F(x), which looks like a series of peaks and valleys that repeat every 4 units. The peaks occur when cos(pi/2 x) = -1, which happens when pi/2 x = (2n + 1) pi/2, where n is an integer. Solving for x, we get x = 2n + 1. Similarly, the valleys occur when cos(pi/2 x) = 1, which happens when pi/2 x = 2n pi, where n is an integer. Solving for x, we get x = 4n.

The directrix of the parabola defined by the equation (x+9)²= -16(y-5) is x=-16(y-5)+9.

Equation is a physical and mathematical statement that describe physical phenomena and the relationship between different physical quantity typically consist of variable simple presenting physical quantity and then it personal variables may be pointed such as you energy.

The directrix of a parabola is the line which is perpendicular to the axis of symmetry and is equidistant from the focus of the parabola. In this case, the axis of symmetry is y=5 and the focus is (9,-16).

The equation of a line perpendicular to the axis of symmetry is y=mx+b where m is the slope of the line and b is the y-intercept. The slope of the line perpendicular to the axis of symmetry is given by the negative reciprocal of the slope of the axis of symmetry. The slope of the axis of symmetry is 0, so the slope of the perpendicular line is undefined.

Using the point-slope form of the equation of a line, we can represent the equation of the directrix as x=-16(y-5)+9. This is because the point (9,-16) is equidistant from the directrix, so the y-intercept of the directrix is -16(5-5)+9 = 9.

Therefore, the directrix of the parabola defined by the equation (x+9)² = -16(y-5) is x=-16(y-5)+9.

When tossing a fair coin, the possible outcomes are a head (H) or a tail (T), each with a probability of 1/2.

To find the probability of getting at least one head in two coin tosses, we can first find the probability of getting no heads (i.e., two tails) and then subtract that from 1 to get the probability of getting at least one head.

The probability of getting two tails is (1/2) * (1/2) = 1/4, since the probability of getting a tail on the first toss is 1/2 and the probability of getting a tail on the second toss is also 1/2, and we multiply these probabilities together to get the joint probability.

Therefore, the probability of getting at least one head in two coin tosses is:

1 - 1/4 = 3/4

So the probability of at least one head in two coin tosses is 3/4 or 0.75.

Step-by-step explanation:

the Price of each rose will be $6.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given,  Masha buys three roses she will have 7 dollars left.

Let's assume the cost of one rose is "x" dollars.

From the first piece of information, we know that if Masha buys three roses, she will have 7 dollars left.

This can be expressed as:

3x + 7 = Masha's initial amount of money

From the second piece of information, we know that Masha needs to borrow 11 dollars to buy nine roses.

This means that the cost of nine roses is:

9x - 11 = Masha's initial amount of money

Since we know that both expressions represent Masha's initial amount of money, we can set them equal to each other:

3x + 7 = 9x - 11

Subtracting 3x from both sides, we get:

7 = 6x - 11

6x = 18

x =3

Therefore, the Price of each rose will be $6.

There are 25 boys in the class out of a total of 40 students. The fraction of students who are boys is 5/8 and the fraction of students who are girls is 3/8.

Let's start by using the information given in the problem to determine the fraction of students who are girls in the class:

Fraction of students who are girls = 1 - Fraction of students who are boys

Fraction of students who are girls = 1 - 5/8

Fraction of students who are girls = 3/8

Now we can use the fraction of girls to find the number of boys and girls in the class:

Let the total number of students in the class be x.

Number of boys = 5/8 * x

Number of girls = 3/8 * x

We know that there are 15 girls in the class, so we can set up an equation:

3/8 * x = 15

Solving for x:

x = 15 * 8/3

x = 40

So there are 40 students in the class. Now we can find the number of boys:

Number of boys = 5/8 * x

Number of boys = 5/8 * 40

Number of boys = 25

Therefore, there are 25 boys in the class.

A correlation coefficient based on an observational study can only measure the strength of the relationship between two variables, and it cannot be used to prove a cause-and-effect relationship.

Even if the correlation is close to -1 or +1, this does not necessarily mean there is a cause-and-effect relationship between the two variables—it could be due to chance. Similarly, if the scatterplot of the data has little vertical variation, this does not necessarily mean there is a cause-and-effect relationship. The only way to prove a cause-and-effect relationship is through a controlled experiment. Therefore, the correlation coefficient based on an observational study can never be used to support a claim of cause and effect.

Answer: the probability of being offered both jobs is 0.05, or 5%

Step-by-step explanation:

To solve this problem, we can use the formula:

P(A or B) = P(A) + P(B) - P(A and B)

where P(A or B) is the probability of getting at least one job offer, P(A) is the probability of getting an offer for job A, P(B) is the probability of getting an offer for job B, and P(A and B) is the probability of getting an offer for both jobs.

Substituting the given values, we get:

0.40 = 0.25 + 0.20 - P(A and B)

Solving for P(A and B), we get:

P(A and B) = 0.25 + 0.20 - 0.40 = 0.05

Therefore, the probability of being offered both jobs is 0.05, or 5% (rounded to two decimal places).

In mathematics, a function is a relation between two sets of values, where each input value from the first set (called the domain) corresponds to exactly one output value in the second set (called the range). The output value of a function is determined by its input value and any relevant rules or formulas.

Formally, a function can be defined as follows: Let X and Y be two non-empty sets. A function f from X to Y is a rule or formula that assigns to each element x in X a unique element y in Y, denoted by f(x), such that for any two elements x1 and x2 in X, if x1 = x2, then f(x1) = f(x2). The set X is called the domain of the function, and the set Y is called the codomain or range of the function.

Functions can be represented graphically, algebraically, or in tabular form. The graph of a function shows how the output value of the function varies with the input value, and can be used to visualize the behavior of the function. The algebraic representation of a function can be given by a formula or equation that expresses the output value in terms of the input value. A tabular representation of a function shows the input-output pairs in a table.

Functions are used in many areas of mathematics, science, engineering, and economics to model and describe relationships between variables. They are also used in practical applications, such as in computer programming, where they are used to define algorithms and data structures.

sin(B) = opposite leg / hypotenuse

We are given that the ratio of the opposite leg to the hypotenuse is 0.96:

opposite leg / hypotenuse = 0.96

So, we can substitute 0.96 for opposite leg / hypotenuse:

sin(B) = 0.96

Now we can use the inverse sine function to find the value of angle B:

B = sin^(-1)(0.96)

Using a calculator, we get:

B ≈ 75.96 degrees

Since angle B is an acute angle in a right triangle, it must be less than 90 degrees. Therefore, a reasonable approximation for angle B is:

Step-by-step explanation:

The general equation of an ellipse is:

[tex]\boxed{\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1}[/tex]

where (h, k) is the center.

The major axis is the longest diameter of an ellipse, and the minor axis is the shortest diameter of an ellipse.

If a > b the ellipse is horizontal, a is the major radius (parallel to the x-axis), and b is the minor radius (parallel to the y-axis).

If b > a the ellipse is vertical, b is the major radius (parallel to the y-axis), and a is the minor radius (parallel to the x-axis).

The given equation is:

[tex]\dfrac{x^2}{49}+\dfrac{y^2}{81}=1[/tex]

Therefore:

As b > a, the ellipse is vertical.

The major axis is 18 units in length and is parallel to the y-axis.

The minor axis is 14 units in length and is parallel to the x-axis.

Both axes pass through the center of the ellipse.

As the center of the ellipse is the origin, the major axis is on the y-axis and the minor axis is on the x-axis.
