The function has a global maximum at the vertex (2/5, 41/25), and there are no local maxima or minima.

To find the critical numbers of the function f(x) = 4 - 5x/4 + x, we first need to find its derivative:

f'(x) = -5/4 + 1

f'(x) = -1/4

To find the critical numbers, we set f'(x) equal to zero and solve for x:

-1/4 = 0

This is never true, so there are no critical numbers for f(x).

Since there are no critical numbers, there are no local maxima or minima for the function. Instead, we can analyze the behavior of the function to determine if it has any extrema.

One way to do this is to examine the end behavior of the function. As x approaches positive or negative infinity, the leading term of the function is -5x/4, which dominates the constant term. Therefore, as x becomes large in either direction, the function approaches negative infinity. This suggests that the function has a global maximum at its vertex.

To find the vertex, we can complete the square:

f(x) = 4 - 5x/4 + x

\(f(x) = -(5/4)x^2 + x + 4\)

\(f(x) = -(5/4)(x^2 - (4/5)x) + 4\)

\(f(x) = -(5/4)(x - 2/5)^2 + 4 + (5/4)(2/5)^2\\f(x) = -(5/4)(x - 2/5)^2 + 41/25\)

Therefore, the function has a global maximum at the vertex (2/5, 41/25), and there are no local maxima or minima.

The equivalence class [a] consists of all integers of the form 5n + (3a - 2k)/2, where n and k are integers such that 5 divides 3a - 2k. In other words, [a] consists of all integers that differ from a by a multiple of 5 and an even integer.

To prove that R is an equivalence relation, we need to show that it satisfies three properties: reflexivity, symmetry, and transitivity.

Reflexivity: For any integer a, we have 3a - 5a = -2a, which is even. Therefore, aRa for all integers a, and R is reflexive.

Symmetry: If aRb, then 3a - 5b is even. This means that there exists an integer k such that 3a - 5b = 2k. Rearranging this equation, we get 5b - 3a = -2k, which is also even. Therefore, bRa, and R is symmetric.

Transitivity: If aRb and bRc, then 3a - 5b is even and 3b - 5c is even. This means that there exist integers k and m such that 3a - 5b = 2k and 3b - 5c = 2m. Adding these equations, we get 3a - 5c = 2k + 2m + 3(5b - 3a), which simplifies to 3a - 5c = 2(k + m + 5b) - 9a. Since k + m + 5b and 9a are both integers, this means that 3a - 5c is even, and aRc. Therefore, R is transitive.

Since R is reflexive, symmetric, and transitive, it is an equivalence relation.

To describe the equivalence classes, we need to find all integers that are related to a given integer under R. Let's consider the integer 0 as an example.

For an integer b to be related to 0 under R, we need to have 3(0) - 5b = -5b be even. This means that b must be odd. Therefore, the equivalence class [0] contains all even integers.

For an integer a ≠ 0, we can rearrange the equation 3a - 5b = 2k as b = (3a - 2k)/5. This means that b is uniquely determined by a and k, as long as 5 divides 3a - 2k.

Therefore, the equivalence class [a] consists of all integers of the form 5n + (3a - 2k)/2, where n and k are integers such that 5 divides 3a - 2k. In other words, [a] consists of all integers that differ from a by a multiple of 5 and an even integer.

Step-by-step explanation:

The exercise involves calculations with matrices A, B, and C. We need to determine if matrix products AB, BA, BC, and CB are defined. Additionally, we need to calculate the specific matrix products and determine if BC is equal to CB.

Let's perform the calculations step by step:

(a) To determine if AB is defined, we need to check if the number of columns in matrix A is equal to the number of rows in matrix B. If they are equal, the matrix product AB is defined. If not, the product is not defined.

Matrix A has 2 columns and matrix B has 2 rows, so the product AB is defined.

Calculating AB:

AB = [23 + 83 20 + 88]

[23 + 03 20 + 08]

= [30 64]

[6 0]

To calculate BA, we need to check if the number of columns in matrix B is equal to the number of rows in matrix A. In this case, matrix B has 2 columns and matrix A has 2 rows, so the product BA is also defined.

Calculating BA:

BA = [32 + 02 38 + 02]

[32 + 02 38 + 02]

= [6 24]

[6 24]

(b) To determine if BC is defined, we need to check if the number of columns in matrix B is equal to the number of rows in matrix C. In this case, both matrices have 2 columns and 2 rows, so the product BC is defined.

Calculating BC:

BC = [26 + 85 23 + 81]

[06 + 05 03 + 01]

= [52 22]

[0 0]

To calculate CB, we need to check if the number of columns in matrix C is equal to the number of rows in matrix B. In this case, matrix C has 2 columns and matrix B has 2 rows, so the product CB is also defined.

Calculating CB:

CB = [62 + 30 68 + 30]

[52 + 10 58 + 10]

= [12 48]

[10 40]

Is it true that BC = CB?

BC = [52 22]

[0 0]

CB = [12 48]

[10 40]

BC and CB are not equal. The matrix product is not commutative, so BC and CB may yield different results.

In summary:

(a) AB is defined and the result is:

AB = [30 64]

[6 0]

BA is also defined and the result is:

BA = [6 24]

[6 24]

(b) BC is defined and the result is:

BC = [52 22]

[0 0]

CB is also defined and the result is:

CB = [12 48]

[10 40]

BC and CB are not equal, indicating that matrix multiplication is not commutative.

The graph will have a gradual increase in speed towards the canyon, followed by a flat line during the rest, a constant positive slope while walking towards the canyon, and finally, a steep decrease in speed as Wile E. runs back to the cave.

In this scenario, let's assume that the positive direction is towards the canyon and the negative direction is towards the cave. Based on the given information, we can draw a qualitative graph of Wile E.'s speed versus time as follows:

From the start, Wile E. accelerates in the positive direction towards the canyon, so the speed gradually increases.

When Wile E. reaches the halfway point, he stops for a short rest. At this point, the graph will show a horizontal line indicating zero speed since he is not moving.

After the rest, Wile E. starts walking towards the canyon at a constant speed. The graph will show a straight line with a positive slope, representing a steady speed.

When Wile E. reaches the canyon, he realizes it's almost time for Animal Planet, so he turns around and runs back to the cave as fast as he can. The graph will show a steep line with a negative slope, indicating a rapid decrease in speed.

Overall, the graph will have a gradual increase in speed towards the canyon, followed by a flat line during the rest, a constant positive slope while walking towards the canyon, and finally, a steep decrease in speed as Wile E. runs back to the cave.

Step-by-step explanation:

The surface described by the equation z = sin(y) is a sinusoidal cylinder.

To visualize the surface, we can consider the equation in terms of the variables x, y, and z. However, since the equation only involves the variable y and the trigonometric function sin(y), we can infer that the surface will vary in the y-direction while remaining constant in the x and z directions.

When we plot the surface, we will have a cylinder shape where the height (z-coordinate) at any given point on the surface is determined by the sine of the y-coordinate. As the value of y changes, the height of the surface will oscillate according to the sine function.

Since the equation does not involve x or z, the surface will have an infinite extent in those directions. It will form a circular cylinder shape with the radius determined by the amplitude of the sine function.

The sketch of the surface will show a cylindrical shape with wavy or sinusoidal variations along the y-axis.

The correct answer is b) unchanged. Cutting a chocolate bar in half does not affect its density.

When a chocolate bar is cut in half, its density remains unchanged. Density is a physical property of a substance that is determined by its mass per unit volume. When the chocolate bar is cut in half, the mass is also divided into two equal parts, resulting in a reduction of the volume by half as well. Since both the numerator and denominator in the density formula change proportionally, the density remains the same.

For example, if the density of a chocolate bar is 1 gram per cubic centimeter, cutting it in half would result in two smaller bars, each with half the volume and half the mass. The density of each of the new bars would still be 1 gram per cubic centimeter, even though they are smaller in size.

The length of the rectangle is approximately 41.34 inches.

Let's assume the width of the rectangle is represented by the variable w. According to the given information, the length of the rectangle is four less than twice the width, which can be expressed as 2w - 4.

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, the perimeter is given as 128 inches. Since a rectangle has two pairs of equal sides, we can set up the equation:

2w + 2(2w - 4) = 128.

Simplifying the equation, we get:

2w + 4w - 8 = 128,

6w - 8 = 128,

6w = 136,

w = 22.67.

So, the width of the rectangle is approximately 22.67 inches. To find the length, we can substitute this value back into the expression 2w - 4:

2(22.67) - 4 = 41.34.

Therefore, the length of the rectangle is approximately 41.34 inches.

In summary, the length of the rectangle is approximately 41.34 inches. This is determined by setting up a system of equations based on the given information: the perimeter of the rectangle being 128 inches and the length being four less than twice the width.

By solving the system of equations, we find that the width is approximately 22.67 inches, and substituting this value back, we obtain the length of approximately 41.34 inches.

Step-by-step explanation:

Let us assume the following things

Work done by 1 man in 1 day is \(\frac{1}{x}\)

Work done by 1 woman in 1 day is \(\frac{1}{y}\)

It is mentioned that

six men + ten women finished in 8 days

So,

\(\frac{6}{x} + \frac{10}{y} = \frac{1}{8}\) .............. (1)

And,

four men + six women finished in 12 days

\(\frac{4}{x} + \frac{6}{y} = \frac{1}{12}\) ...............(2)

Now solve these two equations

And we assume \(\frac{1}{x}\) be u and \(\frac{1}{y}\) be v

So

Now the equation is

\(6u\ + 10v\ = \frac{1}{8} \\\\\4u\ + 6v\ = \frac{1}{12}\)

So,

u = 1 ÷ 48 , v = 0

Therefore x = 48

So the time taken for finish the work is 48 days
