Using a trigonometric relation we will see that the height is  8.62m

On the diagram we can see a right triangle, where we know one of the angles and the adjacent cathetus and we want to find the opposite cathetus.

Then we can use the trigonometric relation:

tan(a) = (opposite cathetus)/(adjacent cathetus)

Replacing the values that we know we will get:

tan(72°) = n/2.8m

2.8m*tan(72°) =n = 8.62m

That is the height.

[tex]\frac{1}{36}[/tex]

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.

The equation for the description for given number is x + 16 = 124

"A number x increases by 16" means that we start with a certain number, which we don't know yet, and then add 16 to it. So, we can represent this as:

x + 16

The next part of the description tells us that the result of this addition is 124. So, we can set up an equation by equating this expression to 124, like this:

x + 16 = 124

This is the equation that represents the given description. To find the value of x, we can solve for it by subtracting 16 from both sides of the equation:

x = 124 - 16

x = 108

So, the value of x that satisfies the given description is 108.

Scheme procedure to generate a list of all subsets of a set:

(define (subsets set)

 (if (null? set)

     '(())

     (let ((rest (subsets (cdr set))))

       (append rest (map (lambda (x) (cons (car set) x)) rest))))))

The subsets procedure takes a set as input and checks if the set is empty. If the set is empty, it returns a list with an empty set as its only element. Otherwise, it calls the subsets procedure recursively on the rest of the set (without the first element) and stores the result in a variable called rest.

It then appends the rest list to the result of mapping a lambda function over the rest list. The lambda function takes an element x from the rest list and conses the first element of the original set to it to create a new subset. This results in a list of all subsets of the original set.

Hence Proved that the sum of two consecutive exponents of the number 5 is divisible by 30. and if two consecutive exponents are 5^n and 5^n+1, then their sum can be written as 5^n-1*30.

Exponentiation is a mathematical operation, written as aⁿ. An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

here, we have,

Let suppose two consecutive exponents of 5 are :

5^n and 5^n+1,

Sum of these exponents is

5^n + 5^n+1

The octagon has rotated 45° when the vertex at T is moved to V. This is because the angle of rotation for a regular octagon is 45° when the vertex at T is moved to V.

An octagon is a two-dimensional shape with eight sides and eight angles. It is a polygon which means it is a closed, two-dimensional shape with straight sides. Octagons are used in architecture and design and are commonly seen in stop signs and floor tiles. The angles of an octagon are all equal and each side is the same length.

The regular octagon has eight equal sides and angles. The angles of an octagon are all of the same size, which is 135°. If the octagon is rotated clockwise about its center, then the vertex at T is moved to V. This means that the octagon will have rotated 45° in order to move T to V.

To calculate the angle of rotation, we can use the formula: angle of rotation = (360°/number of sides). Therefore, the angle of rotation for this octagon will be (360°/8) = 45°.

To confirm this, we can use a protractor to measure the angle between the two lines. The angle between the two lines is 45°. This confirms that the octagon has rotated by 45° as the vertex at T has been moved to V.

Therefore, the octagon has rotated 45° when the vertex at T is moved to V. This is because the angle of rotation for a regular octagon is 45° when the vertex at T is moved to V. This can be confirmed by using a protractor to measure the angle between the two lines.

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.

Answer:

To solve for x, we need to isolate it on one side of the equation by performing inverse operations.

11x - 10 + 80 = 180

First, we combine the constant terms on the left side of the equation:

11x + 70 = 180

Next, we isolate the variable term by subtracting 70 from both sides:

11x = 110

Finally, we solve for x by dividing both sides by 11:

x = 10

Therefore, the solution to the equation 11x - 10 + 80 = 180 is x = 10.

The perpendicular line connecting points F and G results in the formation of a triangle with a 14 square unit surface area.

In mathematics, a coordinate is a set of numbers or symbols that describes an object's position or location in a geometric space. The most popular coordinate system is the Geographic coordinate system, which creates a grid on a surface or in three dimensions using a series of perpendicular lines. Each location on the plane or in space is then uniquely identified by an ordered pair or set of three numbers, respectively, that represent a point's distance from the origin along each of the coordinate system's axes.

Given that points F and G share the same x-coordinate, the line connecting them is perpendicular. A degenerate triangle with negative area will be formed by any point H that shares the same x-coordinate as F and G.

D = √((2-2)2 + (6-(-1),2) = √(49), which =  7.

distance(FH)/7  = 2/7.

distance(GH)/7  = 4/7

Distance(FH) / Distance(GH)  = 1 / 2.

The distance between any two points H(x, y) and F(2,6) or G(2,-1) can be calculated using the distance formula as follows:

distance(FH) is  =  √((x-2) + (y-6)).

Distance (GH) is  =  √((x-2) + (y+1)).

By changing the aforementioned values, we obtain:

√((x-2)**2**y+1**2)/7) = 4/7

(x-2)² + (y+1)² = 16

(x-2)² + (y-6) (y-6)² = 1/4 ((x-2)² + (y+1)²)

By condensing and extending, we obtain:

3(x-2)² + 13(y-6)² = 196

5(x-2)² + 25(y+1)² = 784

7(x-2)² + (y-6)² = 1

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!!

              / |

             /  | 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.

Next, we can use these ratios to find the amount of money for each part of the ratio:

10/30 x £300 = £100

20/30 x £300 = £200

Therefore, the amount of money for the parts of the ratio 10:20 would be £100 and £200 respectively.

The height of the building is approximately 27.62 feet. Rounded to the nearest hundredth, the answer is 27.62 feet.

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.

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

x = 26

Therefore, arc LM = arc NP = 152°

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

Therefore , the solution of the given problem of function comes out to be the limit may not exist, if the function is not continuous at x = 0.

The mathematical discipline encompasses arithmetic, symbols, and their divisions, as well as histology, construction, and both real and imagined geographic places. A function describes the connections between various elements, which all have an associated outcome. A function is composed of an array of different parts that, when combined, result in particular outcomes for each input.

Here,

We must be aware of the precise function or expression under consideration in order to respond to this query.

The action as x moves towards zero from the negative direction can change depending on the function.

If a function is continuous at x = 0, then in general, if the function has a limit as x gets smaller from the downward direction, however this limit will be the same as the limit as x reaches zero from the positive direction.

The limit as x approaches zero from the downward direction may vary from the limit as x approaches zero from the better way, or the limit may not exist, if the function is not continuous at x = 0.

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.

From equation f (x)=7x-9,   f (x+h)= 7h and we can simplify it as 7.

For part (a), we can start by substituting x+h for x in the equation for f(x):

f(x+h) = 7(x+h) - 9

f(x+h) = 7x + 7h - 9

We can then simplify the expression to:

f(x+h) = 7x + 7h - 9

Now, to find f(x+h) - f(x), we can subtract f(x) from both sides of the equation:

f(x+h) - f(x) = 7x + 7h - 9 - (7x - 9)

f(x+h) - f(x) = 7h

Therefore, for part (a) we can conclude that f(x+h) - f(x) = 7h.

Now, we can simplify the difference quotient using f(x+h) and f(x):

f(x+h) - f(x) = [7(x+h) - 9] - [7x - 9]

= 7h

f(x+h) - f(x) / h = 7h / h = 7

We have already simplified the difference quotient  to 7.

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.
