Answer:

n = 3.44

Step-by-step explanation:

The interior angle of a regular n-gon is given by the formula;

\( I = \frac {180(n-2)}{n} \)

Where,

Given that interior angle = 75.2°

Substituting into the equation, we have;

\( 75.2 = \frac {180(n-2)}{n} \)

Cross multiplying, we have;

\( 75.2n = 180(n-2)\)

\( 75.2n = 180n - 360\)

Rearranging the equation, we have;

\( 180n - 75.2n = 360\)

\( 104.8n = 360\)

\( n = \frac {360}{104.8}\)

n = 3.44

Therefore, the number of sides "n" of the regular n-gon described is 3.44.

Answer:d

Step-by-step explanation:

The answer is d. None of the above is true.

To calculate velocity, we need to use the equation:

Velocity = M * P / Y

Given:

M = 1,000

P = 2.25

Y = 2,000

Plugging in the values:

Velocity = 1,000 * 2.25 / 2,000

Simplifying:

Velocity = 2.25 / 2

The result is:

Velocity = 1.125

Therefore, the correct answer is: d. None of the above is true.

Answer:

\(17.3\:\mathrm{m^2}\)

Step-by-step explanation:

Solution 1:

As the angles are marked, the figure forms a 30-60-90 right triangle with the height. Therefore the height will be  \(\frac{4}{2}\cdot\sqrt{3}=2\sqrt{3}\). The area of this figure can be given as \(b\cdot h\), therefore our answer is \(5\cdot 2\sqrt{3}\approx \fbox{$17.3$}\).

Solution 2:

The figure forms two triangles when cut by the shortest diagonal. The area of a triangle can be given by \(\frac{1}{2}ab\sin C\). Since there are 2 of these triangles, the area of the entire figure is \(2\cdot\frac{1}{2}\cdot4\cdot 5\cdot \sin 60^{\circ}\approx \fbox{$17.3$}\).

12 cm, 35 cm, 37 cm measurements could not represent the side lengths of a right triangle. So the option C is correct.

The Pythagorean Theorem states that the sum of the squares of the two shorter sides of a right triangle must equal the square of the longest side.

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two legs (the sides that make the right angle) is equal to the square of the hypotenuse (the side opposite the right angle). Mathematically, this can be written as a² + b² = c².

So the sides of option C "12 cm, 35 cm, 37 cm" could not represent the side lengths of a right triangle because 12 cm² + 35 cm² ≠ 37 cm², these side lengths could not represent a right triangle.

a. The handkerchief symbolizes love and betrayal in "Othello."

b. The song "Willow" represents innocence and impending tragedy.

c. The candle signifies light, hope, and the transient nature of life, often serving as a metaphor for enlightenment and illumination.

The handkerchief, the song "Willow," and the candle are all symbols in the context of the question. Here is the significance of each symbol:
1. The handkerchief: In William Shakespeare's play "Othello," the handkerchief is a symbol of love, trust, and fidelity. It represents the relationship between Othello and his wife, Desdemona. Initially, Othello gives the handkerchief to Desdemona as a token of his love. However, when it goes missing, Othello becomes suspicious and accuses Desdemona of infidelity. The handkerchief's significance lies in its ability to reveal Othello's insecurities and ignite jealousy, ultimately leading to tragic consequences.

2. The song "Willow": The song "Willow" is sung by Desdemona in Act IV, Scene III of "Othello." It serves as a symbol of Desdemona's innocence, vulnerability, and impending doom. Desdemona sings the song while preparing for bed, unaware of the impending tragedy. The lyrics of the song reflect her lament for lost love and foreshadow her impending death. The significance of the song lies in its portrayal of Desdemona's state of mind and her resignation to her fate.

3. The candle: The candle is a symbol of light, truth, and goodness in "Othello." It represents Desdemona's purity and the truth that eventually emerges. In Act V, Scene II, Emilia, Desdemona's maid, discovers the truth about the handkerchief and exposes Iago's deceit. The candle is used metaphorically to symbolize the revelation of truth and the exposure of darkness. It signifies the moment when the truth shines through, bringing justice and exposing the villainy of Iago.

These symbols contribute to the themes of love, trust, betrayal, innocence, and truth in the play "Othello." They enhance the dramatic tension and add depth to the characters and their relationships.

slope: -3/4    y-intercept: 3   equation: y=(-3/4)x+3

Answer: 7w+7=-4+4w+23 = W = 4

First you have to simplify the equations

7w+7= (4w) + (-4+23) 7w+7= 4w+19

Than you have to subtract the 4w (both equation)

7w+7-4w =4w = 4w + 19 - 4w = 3w+7= 19

And than you have to subtract the sevens

3w+7-7=19-7=3w=12

than divide by 3

3w/3 equals 12/3w=4

For this expression,a=15,b=7 and c=4

In this case, the y-values for x = 3 and x = 2.9 are -14 and -13.6, respectively. Therefore, the change in y, or dy, is 0.4.

To compute dy using the function y = -4x - 2 as x goes from 3 to 2.9, we can calculate the difference in y-values between these two x-values.

First, we substitute x = 3 into the equation y = -4x - 2:

y = -4(3) - 2

y = -12 - 2

y = -14

Next, we substitute x = 2.9 into the equation y = -4x - 2:

y = -4(2.9) - 2

y = -11.6 - 2

y = -13.6

The change in y (dy) is the difference between the two y-values:

dy = -13.6 - (-14)

dy = -13.6 + 14

dy = 0.4

To calculate dy, we need to find the change in y-values corresponding to the change in x-values.

By substituting the given x-values into the equation y = -4x - 2, we find the corresponding y-values. The difference between these two y-values represents the change in y, which is denoted as dy.

Therefore, the value of dy, when x goes from 3 to 2.9 using the function y = -4x - 2, is 0.4.

The dimensions of the dining table in Marie's drawing are 1×1.25 ft and the dimensions of the kitchen in Marie's drawing are 3×3.5 ft.

What are the dimensions?

If Marie is drawing everything with dimensions that are 1/4 of the actual size, then the dimensions of the dining table and kitchen in her drawing will be 1/4 of their actual dimensions.

The actual dimensions of the dining table are 4×5 ft. Therefore, the dimensions of the dining table in Marie's drawing will be:

4 ft / 4 = 1 ft by 5 ft / 4 = 1.25 ft

So, the dimensions of the dining table in Marie's drawing are 1×1.25 ft.

Similarly, the actual dimensions of the kitchen are 12×14 ft. Therefore, the dimensions of the kitchen in Marie's drawing will be:

12 ft / 4 = 3 ft by 14 ft / 4 = 3.5 ft

So, the dimensions of the kitchen in Marie's drawing are 3×3.5 ft.

By solving a linear equation, we will see that the points are vertical only if the value of x is -2.

We say that two points (x₁, y₁) and (x₂, y₂) are vertical if the points have the same x-component and different y-component, so we must have:

x₁ = x₂

y₁ ≠ y₂

In this case, the two points are:

F(3-2x, 12) and G(x+9, 7)

The y-component is different, so we only need to have:

3 - 2x = x + 9

This is a linear equation, below I will solve it:

3 - 2x = x + 9

3 - 9 = x + 2x

-6 = 3x

-6/3 = x

-2  =x

The factor that does NOT control the stability of a slope is the angle of repose for intact bedrock. The angle of repose refers to the steepest angle at which a pile of loose material remains stable without sliding. It is mainly applicable to loose materials like soil and granular substances, not intact bedrock.

Bedrock stability depends on factors such as its strength, fracturing, and geological properties, rather than the angle of repose. Factors that control the stability of a slope include whether the slope is rock or soil. Rock slopes tend to be more stable than soil slopes due to the cohesive nature of intact rock.

The amount of water in the soil also affects slope stability, as excessive water can increase pore pressure and reduce the shear strength of the soil, leading to slope failure. Additionally, the orientation of fractures, cleavage, and bedding in the rock can influence slope stability by creating planes of weakness or strength.

To summarize, while the angle of repose is a significant factor in slope stability, it is not applicable to intact bedrock. The stability of a slope is influenced by the type of material (rock or soil), the presence of water, and the orientation of fractures and bedding.

The HCM and LCM of 120 and 180 are 360.

The Highest Common Factor (HCF) of two or more given numbers is the largest number that divides each of the given numbers without leaving any remainder. The Least Common Multiple (LCM) of two or more numbers is the smallest of the common multiples of those numbers.

Given are two numbers as -

120 and 180

We can write 120 and 180 as -

120 = 2 x 2 x 2 x 3 x 5

180 = 2 x 2 x 3 x 3 x 5

HCF of 120 and 180 will be equal to = 2 x 2 x 3 x 5 = 60

Now, we can find LCM using the formula -

LCM(a, b) = (a x b)/HCF(a, b)

LCM(a, b) = (120 x 180)/60

LCM(a, b) = 2 x 180 = 360

Therefore, the HCM and LCM of 120 and 180 are 360.
