Approximate solutions are the estimate values of an equation

The approximate solution of the equation is x = 0.45

The equation is given as:

\(x^3 + 2x- 1= 0\)

The iteration is given as:

\(x_{n+1} = \frac{1}{x_n^2 + 2}\)

To start with, we have:

\(x_1 = 1\)

So, we have:

\(x_2 = \frac{1}{1^2 + 2} = \frac 13 =0.33333333\)

The next iteration is:

\(x_3 = \frac{1}{0.33333333^2 + 2} = 0.47368421102\)

The next iteration is:

\(x_4 = \frac{1}{0.47368421102^2 + 2} = 0.4495641344\)

The next iteration is:

\(x_5 = \frac{1}{0.4495641344^2 + 2} = 0.45411035264\)

The next iteration is:

\(x_6 = \frac{1}{0.45411035264^2 + 2} = 0.45326473189\)

Notice that:

x5 and x6 have the same value to 2 decimal places.

i.e. \(x_5 \approx x_6 = 0.45\)

Hence, the approximate solution of the equation is x = 0.45

Step-by-step explanation:

∂g/∂u is equal to 21u⁵cos⁴(v)sin⁴(v)(cos(v) + u³cos⁴(v)sin²(v)sin(v)).

To find the indicated derivative, we need to use the chain rule. Let's differentiate step by step:

Given:

g(u, v) = f(x(u, v), y(u, v))

f(x, y) = 7x³y³

x(u, v) = ucos(v)

y(u, v) = usin(v)

To find ∂g/∂u, we differentiate g(u, v) with respect to u while treating v as a constant:

∂g/∂u = (∂f/∂x) * (∂x/∂u) + (∂f/∂y) * (∂y/∂u)

To find ∂f/∂x, we differentiate f(x, y) with respect to x:

∂f/∂x = 21x²y³

To find ∂x/∂u, we differentiate x(u, v) with respect to u:

∂x/∂u = cos(v)

To find ∂f/∂y, we differentiate f(x, y) with respect to y:

∂f/∂y = 21x³y²

To find ∂y/∂u, we differentiate y(u, v) with respect to u:

∂y/∂u = sin(v)

Now, we can substitute these partial derivatives into the equation for ∂g/∂u:

∂g/∂u = (21x²y³) * (cos(v)) + (21x³y²) * (sin(v))

To find the simplified form, we substitute the given values of x(u, v) and y(u, v) into the equation:

x(u, v) = ucos(v) = u * cos(v)

y(u, v) = usin(v) = u * sin(v)

∂g/∂u = (21(u * cos(v))²(u * sin(v))³) * (cos(v)) + (21(u * cos(v))³(u * sin(v))²) * (sin(v))

Simplifying further, we get:

∂g/∂u = 21u⁵cos⁴(v)sin⁴(v)(cos(v) + u³cos⁴(v)sin²(v)sin(v))

Step-by-step explanation:

There are 70 ways to split 8 people into two teams of 4. There are 1680 ways to split 9 people into 3 teams of 3. There are 945 ways to choose 2 teams of 4 from 10 prospects.

To find the number of ways to split 8 people into two teams of 4, we can first choose the first team in $\binom{8}{4} = 70$ ways, and the second team will be the remaining 4 people.

To split 9 people into 3 teams of 3, we can first choose the first team in $\binom{9}{3} = 84$ ways. After this, we are left with 6 people, from which we choose the second team in $\binom{6}{3} = 20$ ways. The final team will be the remaining 3 people.

To choose 2 teams of 4 from 10 prospects, we can first choose the first team in $\binom{10}{4} = 210$ ways. After this, we are left with 6 people, from which we choose the second team in $\binom{6}{4} = 15$ ways. However, since the order in which we choose the two teams does not matter, we must divide by 2 to get the final answer of $\frac{210 \cdot 15}{2} = 945$.

Answer:

The correct answer is B: XY=4 cm

Step-by-step explanation:

This is correct because the triangles are both leaning in the same direction so the sides are congruent as stated. Congruent, means that they are equal to each other in other words symmetrical. Because of this, they are the same triangle so where 4 is on the first triangle, it will appear on the same side on the other triangle. This means the answer is B. XY = 4 cm

Answer:

The second one

Step-by-step explanation:

It cant be the first because YZ=4cm

cant be the third because m∠Y= 50°

cant be the forth one because m∠Z= 70°

so, it has to be the second one because XY≅AB

so, if AB=4cm then XY=4cm

m∠D = 40°, m∠F = 65°, and m∠E = 75°. Round to the nearest degree.

Angel is a geometric figure that can be described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°.

To determine the unknown angle measures of △DEF, we can use the fact that the sum of the angles of a triangle is 180°. Thus, if we know two angle measures in the triangle, we can use them to calculate the third.

Let's denote the two known angle measures as m∠D and m∠F. We can use the following equation to solve for the unknown angle measure:

m∠D + m∠F + m∠E = 180°

We can rearrange the equation to solve for m∠E:

m∠E = 180° - m∠D - m∠F

Therefore, once we know the measures of m∠D and m∠F, we can calculate the measure of m∠E.

For example, if m∠D = 40° and m∠F = 65°, then the measure of m∠E would be:

m∠E = 180° - 40° - 65° = 75°

Therefore, m∠D = 40°, m∠F = 65°, and m∠E = 75°. Round to the nearest degree.

The rule that must be used to find out the number of ways that two representatives can be picked, where one is a mathematics major and the other is a computer science major, is the product rule.

The product rule is a fundamental principle in combinatorics that states that if there are m ways to perform one task and n ways to perform another task, then there are m * n ways to perform both tasks together. In this case, we can consider the selection of a mathematics major representative as one task and the selection of a computer science major representative as another task.

To apply the product rule, we need to determine the number of ways each task can be performed. Let's say there are k mathematics majors and j computer science majors available. To select one mathematics major representative, we have k choices, and for the computer science major representative, we have j choices. Therefore, according to the product rule, the total number of ways to pick one mathematics major and one computer science major representative is k * j.

Answer: Let's denote the original number of pages Mark planned to read as "P".

From the first statement, we know that P - 18 pages will take 5 more days, which means P pages will take 5 days less, or 5 - 5 = 0 days.

From the second statement, we know that P - 24 pages will take 8 more days, which means P pages will take 8 days less, or 8 - 8 = 0 days.

So, we have two equations:

P - 18 = 5 * X

P - 24 = 8 * Y

Where X and Y are the number of pages Mark reads per day.

Since X and Y are equal, we can substitute one of them for the other:

P - 18 = 5 * (P - 24) / 8

Expanding the right side and solving for P, we find that P = 288 pages.

The correct negation of the statement "It is sunny" is "It is not sunny." This statement encompasses all possibilities of weather conditions other than sunny.

The negation of the statement "It is sunny" is "It is not sunny."

To understand why this is the case, let's explore the concept of negation in logic. In logic, the negation of a statement flips its truth value. If the original statement is true, then its negation is false, and vice versa.

In the given statement, "It is sunny," the proposition is that the weather condition is sunny.

If we want to negate this statement, we need to express the opposite condition, which is the absence of sun or the presence of non-sunny weather.

By stating "It is not sunny," we are explicitly saying that the weather is anything other than sunny. It could be rainy, cloudy, foggy, or any other condition except for sunny.

Using the other option, "It is rainy," would not be the correct negation in this case.

It would be an alternative statement that contradicts the original claim but does not represent the complete negation of "It is sunny."
