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.

Answer:

Inequality:

29.2x + 501.60 ≤ 560

Answer:

She may buy up to 2 reflectors.

Step-by-step explanation:

She can spend up to $560, so the total expense has to be less than or equal to $560.

total expense ≤ 560

All items she buys have a price and a number of items except for the outfits which have a price but an unknown number.

Let x = number of outfits.

total expense = $425.05 + 4 × $15.19 + $15.79 + x × $29.20

total expense = 29.2x + 501.60

Inequality:

29.2x + 501.60 ≤ 560

29.2x ≤ 58.4

x ≤ 2

She may buy up to 2 reflectors.

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)
= 5(15) - (-2)(9) + 3(3)
= 75 - (-18) + 9
= 75 + 18 + 9
= 102

Therefore, the value of the determinant of the coefficient matrix is 102.

A wheel of 28 cm diameter must rotate 400 times to go 352 m.

Let 'r' represents the radius, 'd' represents the diameter of the wheel.

Here, d = 28 cm

So, r = 14 cm

Let us assume that a wheel needs to rotate 'n' number of times.

We know that the formula for the circumference of circle is 2πr

Let 's' represents the circumference of wheel.

Using above formula,

s = 2 × π × r

s = 2 × 22/7 × 14

s = 44 × 2

s = 88 cm

Now we find the value of n.

First we convert the distance 352 m in centimeters.

352 m = 35200 cm

n = 35200 / s

n = 35200/88

n = 400

The proof is complete.

To prove that there exists a basis in vector space V that satisfies the condition of $W = \{0\}$, we will use the dimension theorem. The dimension theorem states that if $V$ is an $n$-dimensional vector space, then any subspace of $V$ has a dimension that is less than or equal to $n$. 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 $W = \{0\}$. Therefore, the proof is complete.

The number of cubes in the container is 8^(5) and the correct answers are 8^(5) and 8^(7)*8^(-2).

The total volume of the cubes in a container is 8^(7)  cubic centimetersand the volume of each individual cube is 8^(2) cubic centimeters. To find the number of cubes in the container, we need to divide the total volume by the volume of each individual cube.

This can be written as:

Number of cubes = 8^(7) / 8^(2)

Using the rule of exponents, when we divide two numbers with the same base, we can subtract their exponents. In this case, 7 - 2 = 5.

So the number of cubes in the container is:

Number of cubes = 8^(5)

Therefore, the correct answer is 8^(5).

The other option, 8^(7)*8^(-2), is also correct. This is because multiplying two numbers with the same base means we can add their exponents. In this case, 7 + (-2) = 5. So this also gives us the same answer, 8^(5).

In conclusion, the number of cubes in the container is 8^(5) and the correct answers are 8^(5) and 8^(7)*8^(-2).

1- The forecast for June using exponential smoothing with an alpha value of 0.2 and assuming the forecast for Jan is 34 is B. 36.1.

2- The MAD value for the two-month moving average is A. 2.67.

1- The forecast for June using exponential smoothing can be calculated as follows:
Ft = Ft-1 + α(At-1 - Ft-1)
Where Ft is the forecast for the current period, Ft-1 is the forecast for the previous period, At-1 is the actual sales for the previous period, and α is the smoothing constant.

Using the given data and an alpha value of 0.2, the forecast for June can be calculated as follows:

FJan = 34
FFeb = 34 + 0.2(34 - 34) = 34
FMar = 34 + 0.2(36 - 34) = 34.4
FApr = 34.4 + 0.2(39 - 34.4) = 35.32
FMay = 35.32 + 0.2(37 - 35.32) = 35.66
FJune = 35.66 + 0.2(38 - 35.66) = 35.87

Therefore, the forecast for June is 35.87, which is closest to option b. 36.1.

b) Tan x + cot x = 2 csc 2x is an identity.

To verify that each equation is an identity, we will simplify both sides of the equation and show that they are equal.

For part a, we will use the double angle formula for sine and the Pythagorean identity.

sin 2x = 2 sin x cos x

2 tan x / 1 + tan^2 x = 2 sin x / cos x / 1 + sin^2 x / cos^2 x

= 2 sin x / cos x / cos^2 x / cos^2 x

= 2 sin x / cos x / 1 - sin^2 x

= 2 sin x / cos x / cos^2 x

= 2 sin x cos x

Therefore, sin 2x = 2 tan x / 1 + tan^2 x is an identity.

For part b, we will use the definitions of the trigonometric functions and the double angle formula for cosecant.

tan x + cot x = sin x / cos x + cos x / sin x

= (sin^2 x + cos^2 x) / (sin x cos x)

= 1 / (sin x cos x)

= 2 / (2 sin x cos x)

= 2 / sin 2x

= 2 csc 2x

Therefore, tan x + cot x = 2 csc 2x is an identity.

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 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
