Out of the given vectors is in the span of the other vectors,  b. One of the vectors is in the span of the other vector. Since u and v have the same last component, they are linearly dependent, so u is in the span of v and w.

If a set of vectors is linearly dependent, then one of the vectors can be expressed as a linear combination of the other vectors. This means that one vector is in the span of the other vectors. In this case, u can be expressed as a linear combination of v and w, so u is in the span of the other vectors.  

To check for linear dependence, we can first check for a zero row in the matrix formed by the vectors. If there is a zero row, then the vectors are linearly dependent. In this case, the last row of the matrix formed by the vectors is [3,3,0], which is a zero row, so the vectors are linearly dependent.  We can also check for linear dependence by computing the determinant of the matrix formed by the vectors.

The artist charges $25 for a small painting and $65 for a large painting.

How to substitute two equations?

To substitute one equation into another, you can replace one of the variables in the second equation with the expression from the first equation.

Let K be the price of small painting and L be the price of large painting.

From the information given, we know that:

Last month:

6K + 8L = $670 (1)

This month:

12K + 10L = $950 (2)

We have two equations and two unknowns, so we can use a system of equations to find the values of K and L.

Solving the system of equations:

From (1) equation, we have:

6K + 8L = $670

From (2) equation, we have:

12K + 10L = $950

Now we can solve for K (small painting) by multiplying equation (1) by 2 and equation (2) by -1 and adding the two equations together:

12K + 16L = $1340

-12K - 10L = -$950

0K + 6L = $390

Therefore, L = $390 / 6 = $65

Now we can substitute this value of L back into the first equation (1) and solve for K:

6K + 8($65) = $670

6K = $670 - 8($65) = $670 - $520 = $150

K = $150 / 6 = $25

So, the artist charges $25 for a small painting and $65 for a large painting.

Approximately 95.45% of the observations fall between 32 and 48.

Using the Empirical Rule, we can calculate the Z scores for 32 and 48 to see what percentage of observations falls between these values.

First, calculate the Z score for 32:

Z = (32 - 40) / 4 = -2

Next, calculate the Z score for 48:

Z = (48 - 40) / 4 = 2

The Empirical Rule states that approximately 68% of the observations fall within 1 standard deviation of the mean, which is between 36 and 44 in this case. However, since the Z scores for 32 and 48 are both outside of this range, we need to calculate the percentage of observations that falls between these Z scores.

Using a standard normal distribution table, we can see that the percentage of observations between Z = -2 and Z = 2 is approximately 95.45%. This means that approximately 95.45% of the observations fall between 32 and 48.

A, C, B, and D make up the list of ABCD's angles, from largest to smallest, with 90°, 54°, 24°, and 12°, respectively.

The sides of a triangle, or angle, are two rays that make up the figure. The Law of Cosines can be used to find Angle A. We can solve for the angle A by using the formula

                               c² = a² + b² - 2abcos(C).

Since we know the lengths of all sides, we can substitute in the values.                                    

                        c² = 122 + 102 - 2(12)(10)cos(A)

                          Cos(A) = (144 + 100 - 120)/240

                       = 24/240

                       = 0.1

In the end, we use the inverse cosine to determine the angle A, which is roughly 74 degrees.

The same formula can be used to determine Angle D.

                                c² = 62 + 102 - 2(6)(10)cos(D)

                              Cos(D) = (36 + 100 - 60)/120

                                       = 76/120

                                               = 0.63 .

When we take the inverse cosine, we get the angle D, which is about 27.3 degrees.

The same formula can be used to determine Angle C.

                                 c² = 122 + 62 - 2(12)(6)cos(C)

                                      Cos(C) = (144 + 36 - 72)/144

                                                 = 108/144

                                       = 0.75

When we take the inverse cosine, we get the angle C, which is about 36.9 degrees.

The same formula can be used to determine Angle B.

                              c² = 122 + 102 - 2(12)(10)cos(B) .

                               Cos(B) = (144 + 100 - 120)/240

                                                 = 24/240

                                                = 0.1

We obtain the angle B, which is roughly 74 degrees, by applying the inverse cosine.

Therefore, ABCD's angles, from largest to smallest, are as follows: angle C (36.9°), angle B (74°), and angle D (27.3°)

In the isosceles triangle, the size of angle, a is 50°

An isosceles triangle is a type of triangle which has two sides that are equal in length.

This type of triangle has two angles which are the same and the third angle is different from the other two. It also has three sides, with two sides being equal and the third side being different.

The base of the isosceles triangle is the side that has two equal sides, and the sides that are equal are called the legs. The angles that are equal are called the base angles. The point at which the two equal sides meet is called the vertex.

The angles of the isosceles triangle add up to 180 degrees. The base angles are the same, while the third angle is different and can be greater or smaller than the other two angles. This type of triangle is very symmetrical, as the two equal sides create a mirror image of the triangle.

Isosceles triangles are very useful in many areas, such as mathematics, engineering and architecture. In mathematics, isosceles triangles are used to solve problems involving angles, area, and perimeter.

In engineering, they are used in many structures such as bridges. In architecture, they are used to create aesthetically pleasing designs for buildings and monuments.

The trigonometric functions for this angle are sin(0) = -â2/2, cos(0) = -â2/2, and tan(0) = -1. The measure of the reference angle is not 30° or 60°.

The measure of an angle is the amount of rotation from the starting position to the endpoint of the angle. In this problem, the measure of angle is 0 is 7π/4. This means that the angle has rotated 7π/4 radians from the start position, which is equivalent to 360° - (7π/4)*180/π = 315°.

Therefore, the measure of the reference angle is 45°, because the reference angle is the smallest angle that starts at the x-axis and terminates at the terminal side of the angle, which in this case is 315°. The reference angle is equal to the measure of the angle minus the multiple of 360°, so 45° = 315° - 360°.

The trigonometric functions of sine, cosine, and tangent can be used to evaluate the measure of an angle. The sine of an angle is equal to the ratio of the opposite side of the angle over the hypotenuse of the triangle formed by the angle. In this problem, sin(0) = opposite/hypotenuse = -â2/2, since the angle is 7π/4 radians, or 315°.

The cosine of an angle is equal to the ratio of the adjacent side of the angle over the hypotenuse of the triangle formed by the angle. In this problem, cos(0) = adjacent/hypotenuse = -â2/2, since the angle is 7π/4 radians, or 315°.

The tangent of an angle is equal to the ratio of the opposite side of the angle over the adjacent side of the angle. In this problem, tan(0) = opposite/adjacent = -1, since the angle is 7π/4 radians, or 315°.

In conclusion, the measure of angle is 0 is 7π/4, and the measure of the reference angle is 45°. The trigonometric functions for this angle are sin(0) = -â2/2, cos(0) = -â2/2, and tan(0) = -1. The measure of the reference angle is not 30° or 60°.
