The indefinite integral is:

-10 ln|x| + 3 ln|x - 2| + 7 ln|x + 1| + C

First, we factor the denominator of the integrand using partial fractions:

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

We then express the integrand as:

10x^2 - 7x + 2 = A/(x - 2) + B/x + C/(x + 1)

Multiplying both sides by the denominator and solving for A, B, and C, we get:

A = -4, B = 10, C = 1

Thus, we can rewrite the integrand as:

-4/(x - 2) + 10/x + 1/(x + 1)

Integrating each term separately and combining the results, we obtain the final expression for the indefinite integral.

Answer:

A

Step-by-step explanation:

the numbers available in the set is {4,10,22} all are even numbers only.

The basis for the vector space of polynomials of degree at most two which satisfy the constraint is {1 - 2x - 3x²}.

A basis for the vector space of polynomials of degree at most two which satisfy the constraint is {1 - 2x - 3x²}.To find a basis for the vector space of polynomials of degree at most two which satisfy the constraint, we use the following steps:Step 1: We let p(x) = a + bx + cx² and substitute it into the given constraint. That is,p(1) - 3p(0) + 2p(−1) = 0Thus, we get a + b + c − 3a = 0 and a − 2b + c = 0.

These equations can be rewritten as4a − b − c = 0 and a − 2b + c = 0.Step 2: We can solve for a, b, and c by setting up an augmented matrix as shown below:4 −1 −1 | 00 1 −2 | 0Using row reduction, we get the augmented matrix in row echelon form as follows:4 −1 −1 | 00 1 −2 | 0R2 → R2 + 2R1 −> 0 −1 −3 | 00 1 −2 | 0R1 → R1 + R2 -> 4 0 −4 | 00 1 −2 | 0R3 → R3 / (-4) -> 0 0 1 | 0R2 → R2 + 3R3 -> 0 1 0 | 0R1 → R1 + R3 -> 4 0 0 | 0

Therefore, the solution is a = 0, b = 0, and c = 0.Since the only polynomial of degree at most two that satisfies the constraint is the zero polynomial, the vector space of polynomials of degree at most two which satisfy the constraint is a trivial vector space, denoted by {0} Since the dimension of a trivial vector space is 0, then any set containing only the zero vector is a basis for the vector space.

Therefore, the basis for the vector space of polynomials of degree at most two which satisfy the constraint is {0}.Step 5: However, the question is asking for a basis for the vector space of polynomials of degree at most two which satisfy the constraint. Therefore, we need to redo the calculations to account for the fact that there is no nontrivial vector in the vector space of polynomials of degree at most two which satisfy the constraint.

In this case, we can take any non-zero vector as the basis for the vector space of polynomials of degree at most two which satisfy the constraint. For example, we can take p(x) = 1 - 2x - 3x² as the basis. Since p(x) is a polynomial of degree at most two, and it satisfies the constraint p(1) - 3p(0) + 2p(−1) = 0, then it is in the vector space of polynomials of degree at most two which satisfy the constraint. Therefore, the basis for the vector space of polynomials of degree at most two which satisfy the constraint is {1 - 2x - 3x²}.

The coordinate system that is an extension of the terrestrial coordinate system on the celestial sphere is called the celestial coordinate system.

The coordinate system that is an extension of the terrestrial coordinate system onto the celestial sphere is known as the celestial coordinate system.

The celestial coordinate system is used to locate and describe objects in the sky, such as stars, planets, and other celestial bodies.

Similar to the terrestrial coordinate system, the celestial coordinate system utilizes a set of coordinates to specify the position of an object. However, due to the spherical nature of the celestial sphere, the celestial coordinate system has some differences.

In the celestial coordinate system, the celestial sphere is divided into two main components: the celestial equator and the celestial poles.

The celestial equator is an imaginary circle that represents the projection of the Earth's equator onto the celestial sphere. It divides the celestial sphere into the northern and southern celestial hemispheres.

To specify the position of an object in the celestial coordinate system, two primary coordinates are used:

declination (DEC) and right ascension (RA).

Declination is similar to latitude and measures the angular distance of an object north or south of the celestial equator, while right ascension is similar to longitude and measures the angular distance of an object eastward from a reference point known as the vernal equinox.

With the celestial coordinate system, astronomers and stargazers can precisely locate and track celestial objects across the sky, enabling them to study and explore the vastness of the universe.

Answer:

m∠W = 125°

m∠X = 55°

m∠Z = 55°

Step-by-step explanation:

The explanation of angle measures is shown below:-

The shape which is parallelogram WXYZ. m∠Y = 125

A parallelogram represents the shape of quadrilateral in which both opposite sides and opposite angles are similar to each other. One parallelogram diagonals bisect each other. Consecutive angles are also supplementary to a parallelogram.

In WXYZ parallelogram is there

m∠Z + m∠Y = 180° is an angle of Consecutive in a parallelogram is supplementary

m ∠ Z + 125 = 180

m ∠ Z = 180 - 125

m ∠ Z = 55°

m ∠ W which equals to m∠Y where equal angles are Opposite

m∠W = 125°

m ∠ W + m ∠ X = 180°

which is the angle of Consecutive in a parallelogram called supplementary)

m ∠ X + 125 = 180

m ∠ X = 180 - 125

After solving the above equation we will get

m ∠ X = 55°

Solving a system of equations we can see that each pair of pants costs €82.94 and each coat costs €26.37

Let's define the variables:

x = cost of a pant

y = cost of a coat.

First, we know that:

3x + 2y = 245

And then there are discounts of 20% and 5%, and the cost of one of each is 100.75, then:

0.8x + 0.95y = 100.75

Then we have a system of equations:

3x + 2y = 245

0.8x + 0.95y = 100.75

We can isolate x on the second equation to get:

x = (100.75 - 0.96y)/0.8

x = 125.9 - 1.2y

Replace that in the other equation:

3*(125.9 - 1.2y) + 2y = 245

Solving for y:

3*125.9 - 3*1.2y + 2y = 245

y*(2 - 3*1.2) = 245 - 3*125.9

y = (245 - 3*125.9)/(2 - 3*1.2)

y = 82.94

Then the value of x is:

x = 125.9 - 1.2*82.94

We need to find the value of determinant det(AB), using the formula: det(AB) = det(A)det(B)

=> det(AB) = 3 × 5

=> det(AB) = 15.

Hence, the value of det(AB) is 15.

The given matrices are A and B. Here, we need to determine the value of det(AB). To calculate the determinant of the product of two matrices, we can follow this rule:

det(AB) = det(A)det(B).

Given that: det(A) = 3

det(B) = 5

Now, let C = AB be the matrix product. Then,

det(C) = det(AB).

To evaluate det(C), we have to compute C first. We can use the following method to solve the augmented matrix by elementary row operations.

Given matrices A and B are: Matrix A and B:

[A|B] = [3 0 0|1 0 1] [0 3 0|0 1 1] [0 0 3|1 1 0][A|B]

= [3 0 0|1 0 1] [0 3 0|0 1 1] [0 0 3|1 1 0].

We can see that the coefficient matrix is an identity matrix. So, we can directly evaluate the determinant of A to be 3.

det(A) = 3.

Therefore, det(AB) = det(A)det(B)

= 3 × 5

= 15.

Using the half-angle identity to write the expression sin θ/4 using trigonometric functions of θ instead of θ/4 , we get: sin(θ/4) = sin((θ/2) / 2) = ±√((1 - cos(θ/2))/2)

To write the expression sin θ/4 using trigonometric functions of θ instead of θ/4, we can use the half-angle identity for sine. The half-angle identity for sine states that sin(θ/2) = ±√((1 - cosθ)/2), where the sign depends on the quadrant in which θ/2 lies.

To apply this identity to our expression, we can rewrite θ/4 as (θ/2) / 2. Using the half-angle identity, we get:

sin(θ/4) = sin((θ/2) / 2) = ±√((1 - cos(θ/2))/2)

The statement false is:

Expanding the sample size can decrease the power of a hypothesis test.

The correct option is (d)

The significance level is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference.

The level of statistical significance is often expressed as a p -value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. A p -value less than 0.05 (typically ≤ 0.05) is statistically significant.

The probability of making a type I error is α, which is the level of significance you set for your hypothesis test. An α of 0.05 indicates that you are willing to accept a 5% chance that you are wrong when you reject the null hypothesis.

m∠6 = 90°

Step-by-step explanation:

∠1 and ∠2 are a linear pair.  This means they are supplementary, or their measures sum to 180°.  To find m∠2, we subtract m∠1 from 180:

180-140 = 40°

The measure of ∠2 is 40°.

The sum of the measures of the angles in a triangle is 180°.  We have ∠2 and ∠3; to find the measure of ∠6, we subtract these two from 180:

180-(40+50) = 180-90 = 90°
