what's the answer to this question ​

The values of x, y, z, and w are 6, -13, -1, and 4, respectively. So, the answer is 6, -13, -1, 4.

To find a basis for the orthogonal complement of the subspace of R4 spanned by the given vectors, we need to find the null space of the matrix formed by the given vectors. The matrix is:
```
1 -1 7 5
2 -1 1 6
1 0 -6 1
```
We can use the reduced row echelon form to find the null space of this matrix. The reduced row echelon form of this matrix is:
```
1 0 -6 1
0 1 13 -4
0 0 0 0
```
The null space of this matrix is the set of all vectors (x, y, z, w) such that:
```
x - 6z + w = 0
y + 13z - 4w = 0
```
We can write the null space in parametric form as:
```
x = 6z - w
y = -13z + 4w
z = z
w = w
```
We can write the null space in the form {(x, y, 1, 0), (z, w, 0, 1)} by setting z = 1 and w = 0 in the first vector, and setting z = 0 and w = 1 in the second vector. This gives us:
```
x = 6(1) - 0 = 6
y = -13(1) + 4(0) = -13
z = 6(0) - 1 = -1
w = -13(0) + 4(1) = 4
```
Therefore, the basis for the orthogonal complement of the subspace of R4 spanned by the given vectors is {(6, -13, 1, 0), (-1, 4, 0, 1)}. The values of x, y, z, and w are 6, -13, -1, and 4, respectively. So, the answer is 6, -13, -1, 4.

To find a discount, the formula is, List price - (List price x (percentage / 100))

The measure of the smaller angle is 45°.

An heptagon is a figure with 7 sides, and the sum of the interior angles is equal to 900°.

Then here we can write a linear equation that depens on x, where we add all the given angles and we know that it must be equal to 900.

2x + 3x + 4x + 5x + 7x + 9x + 10x = 900

Solving that linaer equation for x:

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

Given are some circles, we need to find the value of x, in each,

Using the properties of the circle, If two chords in a circle are congruent, then their intercepted arcs are congruent, [the main theorem]

1) RS = 59 and ST = 10x-31,

10x-31 = 59

10x = 100

x = 10

2) arc JK = arc ML

Therefore,

7x-39 = 87

7x = 126

x = 18

3) arc AB = arc DC

Therefore,

2(13x-21) = 360°-(arc AD+arc BC)

2(13x-21) = 244

13x-21 = 122

13x = 143

x = 11

4) LM = NP

Therefore,

41-2x = 7x+5

36 = 9x

x = 4

LM = 41-2(4)

= 41-8 = 33

5) arc UV = arc VW

Therefore,

8x-17 = 5x+52

3x = 69

x = 23

arc WV = 5(23)+52 = 167

6) We know, that the distance of two equal chords are same from the center of a circle,

Therefore,

HJ = JI

3x+20 = 15x-64

84 = 12x

x = 7

JI = 105-64

JI = 41

7) Using the converse of the theorem used in question 6, we have,

Chord BC = Chord CD

Again using the main theorem of the question,

arc BC = arc CD

9x-53 = 2x+45

7x = 98

x = 14

arc BAD = 360°-(arc BC + arc CD)

arc BAD = 214°

8) arc LM = arc NP

8x-56 = 5x+22

3x = 78

Negative exponents can be manipulated and solved through exponent properties.

Exponent Properties

There are numerous different exponent properties that allow us to simplify expressions. However, for this question, the important property is known as the negative exponent property. This states that [tex]\displaystyle a^{-b}=\frac{1}{a^b}[/tex]. We can apply this same idea to the question we were given.

Solving

Through the negative exponent property, we know that we can make the exponent positive by taking the reciprocal.

Remember that 6^2 = 36, then solve.

So, the final answer is 1/36.

If the divisor contains 2 or more terms, (6x^(2)y+18x^(2)y^(2)-xy^(2))/(6xy) it can simplifies to x+3xy-y.

To divide the given expression, we need to factor out the common term from the numerator and then simplify by canceling out the common terms from the numerator and denominator. Here is the step-by-step explanation:

Step 1: Factor out the common term from the numerator:
(6x²y+18x²y²)-xy²)/(6xy) = 6xy(x+3xy-y)/(6xy)

Step 2: Cancel out the common terms from the numerator and denominator:
6xy(x+3xy-y)/(6xy) = (x+3xy-y)

Step 3: Simplify the expression:
(x+3xy-y) = x+3xy-y

Therefore, the final answer is x+3xy-y.

If the car moves in a straight line starting from the rest, then the total distance travelled by the toy car is 18m.

We first break the motion of the car into two parts:

So, the first part of the motion.

We know that the car accelerates from rest to a velocity of 5 m/s with a constant acceleration for 4 seconds.

We use the equation of motion : v = u + at;

where v = final velocity, u = initial velocity (which is 0 in this case), a is = acceleration, and t = time.
⇒ a = (v - u)/t

⇒ a = (5 - 0)/4,

⇒ a = 1.25 m/s²

Now, we can use another equation of motion to find the distance travelled during this time:

⇒ s = ut + (1/2)at²

where s=distance travelled, u=initial velocity (which is 0), a=acceleration, and t = time.

Substituting the values,

We get,

⇒ s = 0 + (1/2)(1.25)(4)²

⇒ s = 10 m

So, the distance travelled during the first part of the motion is 10 meters.

In the second part of the motion,

Car decelerates from 5 m/s to a complete stop with a constant deacceleration of 1 m/s² for 2 seconds.

So, we have : s = ut + (1/2)at²

where s = distance travelled, u = initial velocity (5 m/s), a = deacceleration (-1 m/s² ), and t = time.

Substituting the values,

We get,

⇒ s = 5(2) + (1/2)(-1)(2)²

⇒ s = 8m

So, the distance travelled during second part of motion is 8 meters.

The total distance travelled by the car is sum of distances travelled during the motion is :

⇒ Total distance = 10 m + 8 m = 18 m

Therefore, the total distance travelled is 18 meters.

Answer: The horizontal distance from the hot air balloon to the building is approximately 2533.39 meters.

Step-by-step explanation:

We can use trigonometry to solve this problem. Let's draw a diagram to visualize the situation!!

=== begin diagram ===

                B (balloon)

               /|

              / |

             /  | 520m

            /   |

           /θ   |

          /     |

         /______|___ C (ground)

        A       D

=== end diagram ===

In the diagram, we have a hot air balloon at point B that is 520m from the ground at point C. We also have a building at point D that is 450m tall. The angle of elevation from point D to point B is 10 degrees (angle θ).

We want to find the horizontal distance between point B and point D (distance AB in the diagram).

To do this, we can use the tangent function:

tan(θ) = opposite/adjacent

In this case, the opposite side is the height of the building (450m) and the adjacent side is the horizontal distance we want to find (AB). We can rearrange the formula to solve for AB:

AB = opposite/tan(θ)

AB = 450m / tan(10°)

AB ≈ 2533.39m

Therefore, the horizontal distance from the hot air balloon to the building is approximately 2533.39 meters.

That distance is always positive.

b. The absolute value symbol is " | | ".

Part B: |-3 -2| = 1

On the number line, this point represents the distance of one unit from -3 to -2.

|2-(-3)| = 5

On the number line, this point represents the distance of 5 units between 2 and -3.

|-3 + (-2)| = 5

The 5 units at this point on the number line reflect the distance from -3 to -2.

|-3 - (-2)| = 1

On the number line, this point represents the distance of one unit between -3 and -2.

The zeros of P(x)=x^(4)+2x^(3)-7x-14 are 1, -2, and 2.

To find the rational zeros, we need to use the rational zero theorem. This theorem states that any rational zeros of a polynomial must be a factor of the constant term (in this case, -14) divided by a factor of the leading coefficient (in this case, 1).

So, the possible rational zeros of this polynomial are ±1, ±2, ±7, and ±14.

To confirm if these are indeed the zeros of the polynomial, we can plug each of these numbers into the polynomial and determine if the result is 0.

For example, when x=7, P(7) = 7^(4)+2(7^(3))-7(7)-14 = 2401+882-49-14 = 1720. Since the result is not 0, 7 is not a zero of the polynomial.

So when x=2,

P(2) = 2^(4)+2(2^(3))-7(2)-14

       = 16+16-14-14 = 0.

Therefore, 2 is a zero of the polynomial.

The size (n) of the given arithmetic series is 4.

To determine the size (n) of the given arithmetic series, we need to use the formula for the sum of an arithmetic series, which is S_n = (n/2)(a_1 + a_n), where S_n is the sum of the series, n is the number of terms, a_1 is the first term, and a_n is the last term.

In this case, we are given that S_n = 968, a_1 = 38, and the common difference is 10 (since each term is 10 more than the previous one). We need to find the value of n.

Rearranging the formula to solve for n, we get:

n = (2S_n)/(a_1 + a_n)

Substituting in the given values, we get:

n = (2(968))/(38 + a_n)

Since we don't know the value of a_n, we can use the formula for the nth term of an arithmetic series, which is a_n = a_1 + (n-1)d, where d is the common difference. Substituting in the given values, we get:

a_n = 38 + (n-1)(10)

Simplifying, we get:

a_n = 10n + 28

Now we can substitute this value of a_n back into the equation for n:

n = (2(968))/(38 + 10n + 28)

Simplifying, we get:

n = (1936)/(66 + 10n)

Multiplying both sides by (66 + 10n), we get:

n(66 + 10n) = 1936

Expanding, we get:

10n^2 + 66n - 1936 = 0

Using the quadratic formula, we get:

n = (-66 ± √(66^2 - 4(10)(-1936)))/(2(10))

Simplifying, we get:

n = (-66 ± √(19396))/(20)

n = (-66 ± 139.27)/(20)

n = 3.66 or n = -10.26

Since n must be a positive integer, the only valid solution is n = 4.

Yes, we can use the Wronskian to determine whether the following sets of functions are linearly independent. Let's take a look at each set:

Set (a): {cos(x), 3 cos(x) + sin(2x), sin(x)}

To determine if this set of functions is linearly independent, we calculate the Wronskian of the functions. The Wronskian of this set of functions is:

W(cos(x), 3 cos(x) + sin(2x), sin(x)) = -2 cos(2x) - 3 sin(x)

Since the Wronskian is not equal to zero, this set of functions is linearly independent.

Set (b): {e', ce', cº}

To determine if this set of functions is linearly independent, we calculate the Wronskian of the functions. The Wronskian of this set of functions is:

W(e', ce', cº) = e

Since the Wronskian is not equal to zero, this set of functions is also linearly independent.

In conclusion, both sets of functions are linearly independent.
