This verifies that y = cos(4x) also satisfies the differential equation.

The given solutions satisfy the differential equation.

The given differential equation is y'' + 16y = 0, and the proposed solutions are y = sin(4x) and y = cos(4x). To verify, we need to find the second derivative (y'') of each solution and plug it into the equation.

For y = sin(4x), the first derivative (y') is 4cos(4x) and the second derivative (y'') is -16sin(4x). Now, substitute y and y'' into the equation: (-16sin(4x)) + 16(sin(4x)) = 0, which simplifies to 0 = 0. This verifies that y = sin(4x) satisfies the differential equation.

A solution x to the homogeneous linear system of equations Ax = 0 is orthogonal to the row vectors of A because the dot product of x and each row vector in A is equal to 0.

Let's consider a solution, x, to the homogeneous linear system of equations Ax = 0, and discuss why x is orthogonal to the row vectors of A.
The homogeneous linear system of equations can be represented as Ax = 0,

where A is the matrix of coefficients, x is the solution vector, and 0 is the zero vector.

When we say that x is orthogonal to the row vectors of A, we mean that the dot product of x and each row vector is equal to 0.

Let's consider the i-th row vector of A, represented as [tex]a_i.[/tex]

To find the dot product of x and a_i, we multiply the corresponding elements of the two vectors and then sum up the results: [tex]a_i . x = a_i1 \times  x1 + a_i2 \times  x2 + ... + a_in \times  xn.[/tex].
Now, let's recall the matrix-vector multiplication in Ax = 0.

Each element in the result vector 0 is obtained by taking the dot product of a row vector from A and the solution vector x.

So, for the i-th element in the zero vector, we have:[tex]0 = a_i . x.[/tex]

A rhombus is a quadrilateral with all sides of equal length, but its angles are not necessarily equal. The area of the rhombus is √3.

In this case, we are given that one of the angles of the rhombus is 120°. Since opposite angles in a rhombus are congruent, we know that all four angles of the rhombus are 120°.

To find the area of the rhombus, we need to know the length of one of its diagonals. In this case, the shorter diagonal has a length of 2.

The formula for the area of a rhombus is given by the product of the diagonals divided by 2:

Area = (d1 * d2) / 2

Since the rhombus is symmetrical, the diagonals bisect each other at right angles, forming four congruent right-angled triangles. Each of these triangles has a base of 1 (half the length of the shorter diagonal) and a height of √3 (half the length of the longer diagonal).

Therefore, the area of each triangle is (1 * √3) / 2 = √3 / 2.

Since there are four congruent triangles, the total area of the rhombus is 4 * (√3 / 2) = 2√3.

Hence, the area of the rhombus is √3.

The graph of the equation 7x² + 3 = y² is symmetric with respect to B. X-axis and y-axis only.

To test for symmetry with respect to the x-axis, y-axis, and the origin, we need to check if replacing 'x' with '-x', 'y' with '-y', or both leaves the equation unchanged.

For the given equation, when we replace 'x' with '-x', the equation becomes 7(-x)² + 3 = y², which simplifies to 7x² + 3 = y². This indicates that the equation remains the same, so the graph is symmetric with respect to the y-axis.

When we replace 'y' with '-y', the equation becomes 7x² + 3 = (-y)², which simplifies to 7x² + 3 = y². Again, the equation remains the same, indicating symmetry with respect to the origin.

However, when we replace both 'x' with '-x' and 'y' with '-y', the equation becomes 7(-x)² + 3 = (-y)², which simplifies to 7x² + 3 = y². Here, the equation does not remain the same, indicating that the graph is not symmetric with respect to the x-axis.

To visually verify these symmetries, one can use a graphing calculator to plot the graph of the equation. The graph will exhibit symmetry with respect to the y-axis and the origin, but not with respect to the x-axis. Therefore, the correct answer is B. X-axis and y-axis only.

The approximate change in z for the given change in the independent variables is 0.61.

To approximate the change in z for the given change in the independent variables, we can use differentials. The differential of z can be expressed as:

dz = (∂z/∂x)dx + (∂z/∂y)dy

First, let's find the partial derivatives (∂z/∂x) and (∂z/∂y) by taking the partial derivatives of the function z = x^2 - 7xy with respect to x and y, respectively.

∂z/∂x = 2x - 7y
∂z/∂y = -7x

Next, we'll substitute the values of x, y, dx, and dy into the differentials equation. Given that (x, y) changes from (5, 3) to (5.04, 2.97), we have:
x = 5
y = 3
dx = 0.04
dy = -0.03

Substituting these values into the equation dz = (∂z/∂x)dx + (∂z/∂y)dy, we get:

dz = (2(5) - 7(3))(0.04) + (-7(5))( -0.03)
= (10 - 21)(0.04) + (-35)( -0.03)

To determine the size of carpets that will maximize the company's revenue, we need to find the dimensions that will generate the highest total sales. Let's analyze the situation step by step.

We know that the company can sell 200 carpets per week when the size is 3ft by 3ft. Beyond this size, for each additional foot of length and width, the number sold decreases by 4.

Let's denote the additional length and width beyond 3ft as x. Therefore, the dimensions of the carpets will be (3 + x) ft by (3 + x) ft.

Now, we need to determine the relationship between the number of carpets sold and the dimensions. We can observe that for each additional foot of length and width, the number sold decreases by 4. So, the number of carpets sold can be expressed as:

Number of Carpets Sold = 200 - 4x

Next, we need to calculate the revenue generated from selling these carpets. The price per square foot is $5, and the area of the carpet is (3 + x) ft by (3 + x) ft, which gives us:

Revenue = Price per Square Foot * Area

= $5 * (3 + x) * (3 + x)

= $5 * (9 + 6x + [tex]x^2)[/tex]

= $45 + $30x + $5[tex]x^2[/tex]

Now, we can determine the dimensions that will maximize the revenue by finding the vertex of the quadratic function. The x-coordinate of the vertex gives us the optimal value of x.

The x-coordinate of the vertex can be found using the formula: x = -b / (2a), where a = $5 and b = $30.

x = -30 / (2 * 5)

x = -30 / 10

x = -3

Since we are dealing with dimensions, we take the absolute value of x, which gives us x = 3.

Therefore, the additional length and width beyond 3ft that will maximize the revenue is 3ft.

The dimensions of the carpets that the company should sell to maximize its revenue are 6ft by 6ft.

To calculate the maximum weekly revenue, we substitute x = 3 into the revenue function:

Revenue = $45 + $30x + $[tex]5x^2[/tex]

= $45 + $30(3) + $5([tex]3^2)[/tex]

= $45 + $90 + $45

= $180

The equivalent equation for a two-input XOR gate is y = ab’ + a’b.

A two-input XOR gate is a logic gate that outputs a high or 1 signal only when the two inputs are different. In other words, the output of an XOR gate is 1 when one input is 0 and the other input is 1, and vice versa.

To represent an XOR gate with an equation, we can use Boolean algebra. The Boolean expression for an XOR gate is y = ab’ + a’b, where y is the output, a and b are the two inputs, and a' and b' represent the complement (or NOT) of a and b, respectively.

This equation can be derived using the laws of Boolean algebra. For example, we know that the product of a variable and its complement is always 0, i.e., a a' = 0. Using this property, we can simplify the equation y = ab’ + a’b as follows:

y = ab’ + a’b
 = ab’ + ab’’ + a’b     (adding a' and b')
 = ab’ + a’b + ab’’    (rearranging terms)

We can add [tex]\frac{1}{4}[/tex] inside the parentheses because this completes the square, as you will see soon. By adding [tex]\frac{1}{4}[/tex] in the parentheses, we are actually adding [tex]\frac{3}{4}[/tex] to the equation because everything in the parentheses is multiplied by 3. Therefore, we have to add [tex]\frac{3}{4}[/tex] to the other side of the equation to keep both sides equal.

3([tex]x^{2}[/tex]+x+[tex]\frac{1}{4}[/tex])-18=[tex]\frac{3}{4}[/tex]

Add 18 to both sides.

3([tex]x^{2}[/tex]+x+[tex]\frac{1}{4}[/tex])=[tex]\frac{75}{4}[/tex]

Divide by 3 on both sides.

([tex]x^{2}[/tex]+x+[tex]\frac{1}{4}[/tex])=[tex]\frac{25}{4}[/tex]

[tex](x+\frac{1}{2}) ^{2}[/tex]=[tex]\frac{25}{4}[/tex]

Now, take the square root of both sides. Note that there will be a plus minus because squaring the negative of a number will get the same answer as squaring the positive.

x+[tex]\frac{1}{2}[/tex] = ±[tex]\sqrt{\frac{25}{4}}[/tex]

x+[tex]\frac{1}{2}[/tex]=±[tex]\frac{5}{2}[/tex]

Next, we integrate the result with respect to y from 1 to x:

∫ 1+x 1 1/2x^2 dy = 1/2x^2[y]_1^(1+x) = 1/2x^2(1+x-1) = x^3/4

Finally, we integrate the previous result with respect to x from 0 to 1:

∫ 1 0 x^3/4 dx = 1/4 * x^4/4 |_0^1 = 1/16

Let x be the cost of one rose bush and y be the cost of one carnation.

Then we have the system of equations:

x * 9 + y * 12 = 210

x * 3 + y * 1 = 40

To determine the method that is most efficient to solve this system, we can use the fact that one of the equations has already solved for one of the variables, y.

We can use substitution to solve for the other variable, x.

Substitute y = (40 - 3x) into the first equation:

x * 9 + (40 - 3x) * 12 = 210

Simplify:

x * 9 + 480 - 36x = 210

Solve for x:

9x - 36x = 210 - 480

-27x = -270

x = 10

Substitute x = 10 into the second equation:

10 * 3 + y = 40

Solve for y:

y = 10

Therefore, one rose bush costs $10 and one carnation costs $10.

The most efficient method to solve the system was substitution, since one of the equations already solved for one of the variables.

Answer: No solution

Step-by-step explanation:

Hi there, to set up this problem you are first going to draw a triangle and label the angles A, B, and C. The sides opposite from the vertexes are going to be labeled a, b and c. Fill in the information as provided to you in the problem.

You are given angle m<A=123 , the side across is a=45, and c=24. You know to use law of sines for this problem because you are given pieces of information that correspond with the same letter (A and a).

Start by setting up a proportion with that looks like

(45/sin(123)) = (24/sin(C))  

You are looking to solve for the remaining angles and sides, but when you cross multiply and divide, you end up with arcsin(1.573), which does not provide a solution for m<C and also means that there are no solutions to this triangle.

Hope this helps.

The only possible triangle that satisfies the given conditions has sides of length a = 45, b = 57.58, and c = 24, and angle measures of A = 123º, B = 31.7º, and C = 25.3º.

According to the Law of Sines, in a triangle ABC:

a/sin(A) = b/sin(B) = c/sin(C)

Where a, b, and c are the lengths of the sides, and A, B, and C are the opposite angles, respectively.

Using the given information:

a = 45

c = 24

∠a = 123º

We can solve for the remaining parts of the triangle as follows:

sin(A) = a/csc(∠a) = 0.298

Since sin(A) < 1, there is only one possible triangle that can satisfy the given conditions.

Using the Law of Sines:

b/sin(B) = c/sin(C)

b/sin(B) = 24/sin(∠B)

b = 24(sin(A))/sin(∠B) = 57.58
