A hurricane is a big rotating storm system that develops over warm ocean waters and usually travels westward toward the American mainland.

An Atlantic Ocean hurricane or a northern Pacific Ocean hurricane is a tropical storm. In most years, hurricanes develop between June 1 and November 30. The Taino Indian word "hurakan," which means "god of wind," is where the word "hurricane" originates.

A hurricane is a big rotating storm system that develops over warm ocean waters and usually travels westward toward the American mainland. Depending on the maximum sustained wind speeds, hurricanes are either classed as tropical storms or hurricanes. Hurricanes have winds of 74 mph or more, whereas tropical storms have winds of 39 to 73 mph.

The hurricane's eye, which is a calm, clear region encircled by powerful winds, is the most hazardous component of the storm. The hurricane's eye, which can be up to 30 miles across, frequently experiences the storm's greatest rains and highest winds.

A hurricane's landfall can result in flooding from storm surges, strong winds, and heavy rains. The increase in sea level that happens as a cyclone nears land is known as a storm surge. Along with coastal locations, this increase in water level has the potential to inflict significant harm and flooding.

Answer:

\(\huge\boxed{\text{B) } 22.5 \ \text{feet}}\)

Step-by-step explanation:

We can use basic trigonometric functions to find the closest height of the escalator.

Let's set up a picture from what we already know. The length of the escalator is 30 feet, and it forms a 41 degree angle with the top. Since it will form a 90 degree angle with the ground, we can find the angle between the ground and the beginning of the escalator.

Since all triangles have an angle sum of 180:

Now we know that the triangle looks something like this.

                   /  | 41°

                 /    |

               /      |

     /                |

  /                   |

/__________| 90°

49°

We need to find the length of the side between the 41 and 90° angle.

To find which trigonometric operation to use on this triangle, we can use the acronym SOH CAH TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

We can use the sine of the 49 degree angle (opposite / hypotenuse) to find our missing side (since we know the hypotenuse).

Let's set up an equation and solve with our calculator.

We can calculate the sine of 49 with our calculator. We'd end up multiply 30 and that value and get 22.6.

Since the closest value to 22.6 on the answer choices is 22.5, the correct answer would be B) 22.5 feet.

The standard form of the circle is (x + 3)^2 + (y + 10)^2 = 36.

Given, the endpoints of the diameter of a circle are (-9, -10) and (3, -10).

We know that the midpoint of a diameter of a circle is its center, so let's find the midpoint of the given diameter:(midpoint) =  [(x1 + x2)/2,

(y1 + y2)/2]= [( -9 + 3)/2, (-10 -10)/2]= [ -6/2,-20/2]= [ -3, -10]

Therefore, the center of the circle is (-3, -10).

We also know that the radius of the circle is half the length of the diameter, so the radius is:r = (1/2) * [sqrt{(3 - (-9))^2 + (-10 -(-10))^2}] = (1/2) * [sqrt{12^2}] = 6

So, the equation of the circle in standard form is: (x - h)^2 + (y - k)^2 = r^2(x - (-3))^2 + (y - (-10))^2 = 6^2(x + 3)^2 + (y + 10)^2 = 36

The standard form of the equation of the circle is (x + 3)^2 + (y + 10)^2 = 36.

x = 41°

The answer is "The length of the original piece of metal is 15 inches and the width of the original piece of metal is 7 inches."

Let the width of the original piece of sheet metal be "w" and let its length be "l".Then, according to the statement provided by the problem,"A rectangular piece of sheet metal has a length that is 6 inches less than three times the width."Hence, we can write: l = 3w - 6

This is a linear equation in two variables (l and w).We are also told that square pieces of 3 inches are cut from each corner of the rectangular sheet. Therefore, after cutting the squares, the length of the new rectangular piece of sheet metal will be (l - 2(3)) and its width will be (w - 2(3))

i.e. subtracting twice the length of the squares from the length and width, respectively of the original rectangular piece of sheet metal.After this, the sides of the resulting rectangular piece are bent up to form a box, with volume of 315 cubic inches.

Therefore, we can write:V = length × width × height 315 = (l - 6) × (w - 6) × 3

However, since l = 3w - 6, we can substitute this expression for "l" in terms of "w" in the above equation to obtain:

315 = (3w - 6 - 6) × (w - 6) × 3315 = (3w - 12) × (w - 6) × 3

Thus, we have reduced the problem to a cubic equation in one variable "w".

By solving this equation we get:w³ - 15w² + 72w - 105 = 0We can find that one of its roots is w = 7 (which corresponds to the width of the original rectangular piece of sheet metal).Now we can use this value of "w" to find the corresponding value of "l".According to the expression l = 3w - 6, we get:l = 3(7) - 6 = 15

Therefore, the width of the original piece of sheet metal is 7 inches and the length is 15 inches. As we know that the length of the sheet is 6 inches less than three times the width, therefore, the width of the sheet metal will be 7 inches. Hence the length of the sheet metal will be 15 inches.

Let us verify whether the volume of the rectangular box is 315 cubic inches or not. As we know that the length of the rectangular box is 15 - 6 = 9 inches and the width is 7 - 6 = 1 inch and the height is 3 inches.Therefore, the volume of the box = length × width × height= 9 × 1 × 3= 27 cubic inches

We need to find the length and width of the original piece of metal, which is 15 and 7 inches, respectively. Hence, the answer is "The length of the original piece of metal is 15 inches and the width of the original piece of metal is 7 inches."

To find a quadratic equation with the y-intercept and vertex, follow these steps: identify the coordinates of the y-intercept and vertex, substitute them into the general form of the quadratic equation, solve for the coefficients, and substitute the coefficients back into the equation. For example, if the y-intercept is (0, 3) and the vertex is (-2, 1), the quadratic equation would be y = x^2 + x + 3.

To find a quadratic equation with the y-intercept and vertex, we can follow these steps:

For example, let's say the y-intercept is (0, 3) and the vertex is (-2, 1). We can substitute these coordinates into the general form of the quadratic equation:

3 = a(0)^2 + b(0) + c

1 = a(-2)^2 + b(-2) + c

Simplifying these equations, we get:

c = 3

4a - 2b + c = 1

By substituting c = 3 into the second equation, we can solve for a and b:

4a - 2b + 3 = 1

4a - 2b = -2

2a - b = -1

By solving this system of equations, we find a = 1 and b = 1. Substituting these values back into the general form of the quadratic equation, we obtain the final equation:

y = x^2 + x + 3

The linear model that represents the cost of any number of candy bars can be written as: C = $1.90B + $0.95

To write the linear model that models the cost of any number of candy bars, we need to find the equation of a line that best fits the given data points. We'll use the variables B for the number of candy bars purchased and C for the total cost of the candy bars.

Looking at the given data, we can see that there is a linear relationship between the number of candy bars and the total cost. As the number of candy bars increases, the total cost also increases.

To find the equation of the line, we need to determine the slope and the y-intercept. We can use the formula for the equation of a line: y = mx + b, where m is the slope and b is the y-intercept.

First, let's find the slope (m) using two points from the given data, for example, (3, $6.65) and (25, $48.45):

m = (C2 - C1) / (B2 - B1)

 = ($48.45 - $6.65) / (25 - 3)

 = $41.80 / 22

 ≈ $1.90

Now, let's find the y-intercept (b) using one of the data points, for example, (3, $6.65):

b = C - mB

 = $6.65 - ($1.90 * 3)

 = $6.65 - $5.70

 ≈ $0.95

Therefore, the linear model that represents the cost of any number of candy bars can be written as:

C = $1.90B + $0.95

This equation represents a linear relationship between the number of candy bars (B) and the total cost (C). For any given value of B, you can substitute it into the equation to find the corresponding estimated total cost of the candy bars.

Hope this helps!

Answer:

Dividend=Divisor×Quotient+Remainder

So, Applying it:−

Let q(x),k(x) be quotient when f(x) is divided by x−1 and x−2 respectively

⇒f(x)=(x−1)q(x)+5

∴f(1)=5 ..... (1)

Also,f(x)=(x−2)k(x)+7

∴f(2)=7 ..... (2)

Now, let ax+b be the remainder when f(x) is divided by (x−1)(x−2) and g(x) be the quotient.

f(x)=(x−1)(x−2)g(x)+(ax+b)

Using (1) and (2)

5=a+b ...... (3)

7=2a+b ...... (4)

Solving (3) and (4), we get

a=2 and b=3

∴2x+3 is the remainder when f(x) is divided by (x−1)(x−2).

5x + -4 = 40

Reorder the terms:

-4 + 5x = 40

Solving

-4 + 5x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 5x = 40 + 4

Combine like terms: -4 + 4 = 0

0 + 5x = 40 + 4

5x = 40 + 4

Combine like terms: 40 + 4 = 44

5x = 44

Divide each side by '5'.

x = 8.8

In the following polynomial,

3x(6x² - 17x + 12​)

We have to factor the second term of the multiplication in order to have it completely factorized

We want to factor it by grouping

Step 1

We split the middle term:

since

-17 = -9 -8, then

6x² - 17x + 12 = 6x² - 8x - 9x + 12

Step 2

We group into pairs:

6x² - 8x - 9x + 12 = (6x² - 8x) - (9x - 12)

Step 3

We factor each bynomial:

First bynomial 6x² - 8x:

Since

2 · 3 = 6

2 · 4 = 8

then

6x² - 8x = 2 · 3x² - 2 · 4x

We can observe that 2 · 3x² and 2 · 4x have two common factors: 2 and x. Then

6x² - 8x = 2x(3x - 4)

Second bynomial 9x - 12:

Since

3 · 3 = 9

3 · 4 = 12

then

9x - 12 = 3 · 3x - 3 · 4

We can observe that 3 · 3x and 3 · 4 have one common factor: 3. Then

9x - 12 = 3(3x - 4)

Step 4

We can replace the results found in the last step:

6x² - 17x + 12

= (6x² - 8x) - (9x - 12)

= 2x(3x - 4) - 3(3x - 4)

We observe that 2x(3x - 4) and 3(3x - 4) have a common factor: (3x - 4)

Then, we can factorise:

= 2x(3x - 4) - 3(3x - 4)

= (3x - 4)(2x - 3)

Therefore

6x² - 17x + 12 = (3x - 4)(2x - 3)

Using this we can replace in the original expression

According to the empirical rule, the bell or mound-shaped distribution will have approximately 68% of the data within one standard deviation of the mean. This means that if the data is normally distributed, then about 68% of the data points will fall within one standard deviation above or below the mean.

Similarly, the empirical rule states that approximately 95% of the data will fall within two standard deviations of the mean, and about 99.7% of the data will fall within three standard deviations of the mean.

This means that if the data is normally distributed, then 95% of the data points will fall within two standard deviations above or below the mean, and 99.7% of the data points will fall within three standard deviations above or below the mean.

It is important to note that the empirical rule is based on the assumption that the data is normally distributed. If the data does not follow a normal distribution, then the empirical rule may not apply.

The first four terms of the Taylor series for the function (2x) about the point (a=1) are (2x + 2x - 2).

To find the first four terms of the Taylor series for the function (2x) about the point (a = 1), we can use the general formula for the Taylor series expansion:

\(\[f(x) = f(a) + f'(a)(x-a) + \frac{f''(a)}{2!}(x-a)^2 + \frac{f'''(a)}{3!}(x-a)^3 + \ldots\]\)

Let's calculate the first four terms:

Starting with the first term, we substitute

\(\(f(a) = f(1) = 2(1) = 2x\)\)

For the second term, we differentiate (2x) with respect to (x) to get (2), and multiply it by (x-1) to obtain (2(x-1)=2x-2).

\(\(f'(a) = \frac{d}{dx}(2x) = 2\)\)

\(\(f'(a)(x-a) = 2(x-1) = 2x - 2\)\)

Third term: \(\(f''(a) = \frac{d^2}{dx^2}(2x) = 0\)\)

Since the second derivative is zero, the third term is zero.

Fourth term:\(\(f'''(a) = \frac{d^3}{dx^3}(2x) = 0\)\)

Similarly, the fourth term is also zero.

Therefore, the first four terms of the Taylor series for the function (2x) about the point (a = 1) are:
