The constant of variation k for this relationship is 4.

To find the constant of variation k for the given relationship, we can use the formula for direct and inverse variation:

k = (r * y^2) / √n

Where r is the variable that varies directly as the square root of n, and inversely as the square of y. To find the value of k, we can plug in the values of r, y, and n into the equation and solve for k.

For example, if r = 4, y = 2, and n = 16, we can plug these values into the equation to find k:

k = (4 * 2^2) / √16
k = (4 * 4) / 4
k = 16 / 4
k = 4

Therefore, the constant of variation k for this relationship is 4.

If there are 8 tickets and they all add up to $76, you have to divide 76 by 8 (the number of tickets)

The degree of the given polynomial is 2 and the leading coefficient is 5. The given expression is 5a^(2)+2a+6. It is a polynomial expression.

The degree of a polynomial is the highest power of the variable in the polynomial. In this case, the highest power of the variable a is 2, so the degree of the polynomial is 2.

The leading coefficient of a polynomial is the coefficient of the term with the highest power of the variable. In this case, the term with the highest power of the variable a is 5a^(2), so the leading coefficient is 5.

Therefore, the degree of the given polynomial is 2 and the leading coefficient is 5.

The magnitude of the resultant force  ||FR|| is 80.55 N.

The weight of the box is acting straight downward, perpendicular to the incline, so it does not affect the magnitude of the resultant force parallel to the incline. Therefore, we only need to consider the force of 150 N pushing the box up the incline.

Let's call the angle between the force of 150 N and the incline "theta". We can find theta by subtracting 58 degrees from 90 degrees (since the incline is at an angle of 58 degrees with respect to the horizontal). So:

theta = 90 degrees - 58 degrees

theta = 32 degrees

Now we can use trigonometry to find the component of the force of 150 N parallel to the incline. We'll use sine, since we know the hypotenuse (the force) and the opposite side (the component parallel to the incline):

sin(theta) = opposite/hypotenuse

sin(32 degrees) = ||FR||/150 N

Solving for ||FR||, we get:

||FR|| = 150 N * sin(32 degrees)

||FR|| ≈ 80.55 N

Therefore, the magnitude of the resultant force is approximately 80.55 N.

The required slope of the line shown in the graph is 4/3, and the lines representing the rise and run are shown in the graph.

The slope of a line is a measure of how steeply the line is inclined with respect to the horizontal axis.

Here,

To calculate the slope of a line from the rise and run values, we use the formula:

slope = rise/run

In this case, rise = 6 and run = 4.5. Substituting these values into the formula, we get:

slope = 6 / 4.5

Simplifying the fraction by dividing both the numerator and denominator by 1.5,

slope = 4/3

To solve this problem, we can use a system of equations. Let's call the number of main-floor seats x and the number of balcony seats y.
The first equation can be written as:
10x + 4y = 5800
The second equation can be written as:
0.3x + 0.5y = 1900

Now we can use the elimination method to solve for one of the variables. Let's multiply the second equation by -10 to eliminate the x variable:
-3x - 5y = -19000
Adding the two equations together gives us:
7x - y = 3900
Now we can use substitution to solve for one of the variables. Let's solve for y in the first equation:
y = (5800 - 10x)/4
And substitute this value into the second equation:
7x - (5800 - 10x)/4 = 3900
Multiplying both sides by 4 gives us:
28x - 5800 + 10x = 15600
Solving for x gives us:
38x = 21400
x = 563.16
And plugging this value back into the first equation to solve for y gives us:
y = (5800 - 10(563.16))/4
y = 609.21
So there are approximately 563 main-floor seats and 609 balcony seats.

Answer:

x = 106 degrees

Step-by-step explanation:

we can create a triangle with angles x, 30, and 26+18.

that means x + 30 + (26 + 18) = 180.

move the constants to one side to get x = 180 - 30 - (26 + 18) = 106

The equation are: x = -1 radians (-57.3°) and x = 11 radians (626.9°).

To solve this equation, use the identity sin2x + cos2x = 1 and apply it to the left side of the equation.

2 sin2x + 20 cos x = 6

2 (1 - cos2x) + 20 cos x = 6

2 - 2 cos2x + 20 cos x = 6

2 cos2x - 20 cos x + 2 = 6

cos2x - 10 cos x + 1 = 0

Next, solve the resulting quadratic equation using the quadratic formula: x = [-b ± √(b2 - 4ac)]/2a. In this case:

x = [-(-10) ± √((-10)2 - 4(1)(1))]/2(1)

x = [10 ± √(100 - 4)]/2

x = [10 ± √(96)]/2

x = (10 ± 4√6)/2

x = (10 ± 12)/2

x = 5 ± 6

We then use the interval [0,2π) to calculate the exact radian values for x. The two solutions in this interval are:

x = 5 - 6 = -1

x = 5 + 6 = 11

For reference, the angle corresponding to -1 radians is -57.3° and the angle corresponding to 11 radians is 626.9°.
To check the solution, graph the two sides of the equation on Desmos, with the interval [0,2π). The graph will show the two points of intersection (marked with circles) which correspond to the two solutions.

In conclusion, the exact values of x which satisfy the equation are: x = -1 radians (-57.3°) and x = 11 radians (626.9°).

What is the equivalent expression?

In mathematics, an equivalent expression is one that has the same value or meaning as another expression, even though it may look different. In other words, two expressions are equivalent if they simplify to the same value or form.

To simplify the expression [tex](3m^{(-4)})^3 * (3m^5)[/tex], we need to apply the power of a power property of exponents, which states that [tex](a^b)^c = a^(b*c)[/tex].

Using this property, we can rewrite [tex](3m^{(-4)})^3[/tex] as [tex]3^3[/tex] * [tex](m^{(-4)})^3 = 27 * m^{(-12)[/tex]. Similarly, we can rewrite (3m⁵) as 3 * m⁵.

Substituting these values back into the original expression, we get:

[tex](3m^{(-4)})^3 * (3m^5) = 27 * m^{(-12)} * 3 * m^5[/tex]

[tex]= 81 * m^{(-12+5)[/tex]

J is a maximal ideal.

1. To prove that A/J is a commutative ring with unity, note that the operations of addition and multiplication on A/J are well-defined and are commutative since they are inherited from the commutative ring A. Furthermore, the additive identity of A is the same as the additive identity of A/J, and therefore A/J has a unity.
2. Suppose first that J is a prime ideal of A. Then, if A/J is not an integral domain, there exist two nonzero elements x,y of A/J such that xy=0. This means that x and y are in the same coset of J in A. Thus, x-y is an element of J. Since J is prime, either x or y must be in J, which is a contradiction. Therefore, A/J is an integral domain. Conversely, if A/J is an integral domain, then the same argument can be reversed to show that J is a prime ideal.
3. If J is a maximal ideal of A, then A/J is a field by the fact proved in this chapter. Since a field is an integral domain, J is a prime ideal.
4. Suppose that A/J is a field. Then, for any ideal I of A, either I is contained in J or J is contained in I. This implies that J is a maximal ideal.

The value of the determinant of the coefficient matrixis 102.

A coefficient matrix in linear algebra is a matrix made up of the coefficients of the variables in a group of linear equations. In order to solve systems of linear equations, the matrix is used.

The value of the determinant of the coefficient matrix can be found by expanding the determinant along the second row. The coefficient matrix is:

| -3 0 -6 |
| 5 -2 3 |
| 2 -1 -7 |

Expanding the determinant along the second row, we get:

= 5(-1)³(-3(-7) - (-6)(-1)) - (-2)(-1)⁴((-3)(-7) - (-6)(2)) + 3(-1)⁵((-3)(-1) - (0)(2))
= 5(21 - 6) - (-2)(21 - 12) + 3(3 - 0)

In this case, the given subspace $W$ has a dimension of $n-1$ and so it must be a subspace of $V$. Since the dimension of $W$ is less than the dimension of $V$, the dimension theorem states that there exists a basis in $V$ that satisfies the condition of $W = \{0\}$.

If a = -3 when g = 9, the two values for a, which will make g equal 25 will be ± 9/5.

If G is inversely proportional to the square of A, then we can write the relationship as:
