Answer: The distance (x) from the plane to the airport is approximately 2.2 miles.

Step-by-step explanation: The tangent function relates the opposite side of a right triangle to its adjacent side. In this case, we can use it to find the distance (x) from the plane to the airport.

To calculate x, we first need to convert 500 ft to miles. Since there are 5,280 feet in a mile, 500 ft is equal to 0.0947 miles.

Next, we use the tangent function to find x. The tangent of an angle is equal to the opposite side divided by the adjacent side. In this case, we know that the angle of descent is 13 degrees and that the opposite side is x (the distance from the plane to the airport), and we just calculated that the adjacent side is 0.0947 miles. So we can set up an equation:

tan(13 degrees) = x / 0.0947 miles

To solve for x, we can multiply both sides by 0.0947 miles:

0.0947 miles * tan(13 degrees) = x

Plugging this into a calculator gives us:

x = 0.023 miles

Finally, we round this value to the nearest tenth of a mile:

x ≈ 2.2 miles

So, the distance from the plane to the airport is approximately 2.2 miles.

Hope this helps, and have a great day!

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

We have two types of fractions.

Proper fraction and improper fraction.

A proper fraction is a fraction whose numerator is less than the denominator.

An improper fraction is a fraction where the numerator is greater than the denominator.

Example:

1/2, 1/3 is a fraction.

1/4 is a fraction.

We have,

Let's assume that the total number of floors in the skyscraper is "x".

According to the problem, the builder has built 1/6 of the floors.

So the number of floors built by the builder is:

= (1/6)x

The problem also tells us that the builder has built 13 floors.

So we can set up the equation:

(1/6) x = 13

To solve for "x", we can multiply both sides by 6:

x = 78

Therefore,Therefore, The skyscraper will have 78 floors when it is finished.

there are 45,360 distinguishable arrangements of the letters in the word "SASKATOON" and  there are 34,650 distinguishable arrangements of the letters in the word "MISSISSIPPI".

a. SASKATOON:

To determine the number of distinguishable arrangements of the word "SASKATOON", we can use the formula for permutations of indistinguishable objects, which is n!/a!b!c!…, where n is the total number of objects and a, b, c,… are the frequencies of each indistinguishable object. In this case, there are 9 letters in the word "SASKATOON", but some of them are repeated. Specifically, there are 2 S's, 2 A's, and 2 O's. Using the formula, we get:

9!/(2!2!2!) = 9876543/(222) = 45,360

Therefore, there are 45,360 distinguishable arrangements of the letters in the word "SASKATOON".

b. MISSISSIPPI:

To determine the number of distinguishable arrangements of the word "MISSISSIPPI", we can use the same formula for permutations of indistinguishable objects. In this case, there are 11 letters in the word "MISSISSIPPI", but some of them are repeated. Specifically, there are 4 I's, 4 S's, and 2 P's. Using the formula, we get:

11!/(4!4!2!) = 34,650

Therefore, there are 34,650 distinguishable arrangements of the letters in the word "MISSISSIPPI".

In summary, the number of distinguishable arrangements of a word can be found using the formula for permutations of indistinguishable objects, which takes into account the frequency of each repeated letter. By applying this formula to the words "SASKATOON" and "MISSISSIPPI", we find that there are 45,360 and 34,650 distinguishable arrangements, respectively.

The composition of transformations that map ABCD to EHGF is: reflect over the x-axis, then translate (x + 3. y + 1).

In Mathematics and Geometry, a reflection over the x-axis is modeled by this transformation rule (x, y) → (x, -y). This ultimately implies that, a reflection over the x-axis would maintain the same x-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

Since triangle ABCD was reflected over the x-axis, the coordinate A of triangle ABCD can be calculated as follows;

(x, y)            →      (x, -y)

A (-5, 2)      →      (-5, -(2)) = (-5, -2)

For the translation, we have:

(x, y)            →       (x + a, y + b)

A (-5, -2)           →      E (-2, 1)

What is meant by cyclic quadrilateral?

A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. It is also sometimes called inscribed quadrilateral. The circle which consists of all the vertices of any polygon on its circumference is known as the circumcircle or circumscribed circle.

A cyclic quadrilateral means a quadrilateral that is inscribed in a circle. That means there is a circle that passes through all four vertices of the quadrilateral. The vertices are said to be concyclic. The center of the circle is known as the circumcenter and the radius of the circle is known as the circumradius. In the figure given below, ABCD is a cyclic quadrilateral with a, b, c, and d as the side-lengths and p and q as the diagonals.

A number line is a graphical representation of numbers in a linear format. It is a useful tool to help visualize the relative positions of numbers, especially fractions.

To place the fractions 2/3, 1/10, and 7/8 on a number line, we need to first identify their relative positions in terms of magnitude.

Starting at 0 on the number line, we can place 1/10 to the right of 0, followed by 2/3 and then 7/8, in order from left to right. Since 2/3 is greater than 1/10 but less than 7/8, it is placed between these two fractions on the number line. The resulting number line would show the relative positions of these three fractions in relation to each other and to the whole numbers. This can help in comparing and ordering fractions, as well as in visualizing their relative magnitudes.

Company revenue quadratic function.

Angel

The revenue, in billions of dollars, for a company in the year 2002 was $2.7 billion. One year later, in 2003, the revenue had risen to $3.4 billion. In 2005, the revenue climbed to $3.9 billion, before falling to $2.7 billion in 2008. The revenue, r, in billions of dollars, for the company, is a quadratic function of the number of years since 2002, x. what is the vertex of the function?

To find the quadratic function that represents the revenue of the company as a function of the number of years since 2002, we can use the vertex form of a quadratic function:

r(x) = a(x - h)^2 + k

where a is the coefficient of the quadratic term, h is the x-coordinate of the vertex, and k is the y-coordinate of the vertex.

We can use the given revenue values to set up a system of three equations:

2.7 = a(0 - h)^2 + k

3.4 = a(1 - h)^2 + k

2.7 = a(6 - h)^2 + k

Subtracting the first equation from the second, and the first equation from the third, we get:

0.7 = a(1 - h)^2

0 = a(6 - h)^2

Since a cannot be zero (otherwise we wouldn't have a quadratic function), we can divide the second equation by the first to get:

6 - h = 10

which gives us h = -4.

Substituting h = -4 into the first equation, we get:

2.7 = a(0 - (-4))^2 + k

2.7 = 16a + k

Substituting the revenue value for 2005, we get:

3.9 = a(3 - (-4))^2 + k

3.9 = 49a + k

Solving for a and k, we get:

a = -0.1

k = 4.3

Therefore, the quadratic function that represents the revenue of the company as a function of the number of years since 2002 is:

r(x) = -0.1(x + 4)^2 + 4.3

The vertex of this function is at (-4, 4.3).

What is the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101?

We can notice that the sequence alternates between adding an odd number and subtracting an even number. The first term is 3, which is odd, so the sequence starts by adding an odd number. The second term is -4, which is even, so the sequence then subtracts an even number. This pattern continues, so the sum of the sequence can be written as:

3 - 4 + 5 - 6 + ... + 101

We can group the terms into pairs:

(3 - 4) + (5 - 6) + ... + (99 - 100) + 101

Each pair of terms adds up to -1, so we can simplify the expression to:

-1 -1 -1 ... -1 + 101

where there are 50 pairs of -1's. The sum of 50 -1's is -50, so the sum of the sequence is:

-50 + 101 = 51

Therefore, the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101 is 51.

The coordinates of the vertex B' are (-2, -3)

The term vertices (singular: vertex) refers to the points where the sides or edges of a geometric shape or object meet.

The coordinates vertex B', we need to reflect the point B (-2, 5) across the line y = 1.

The line y = 1 is the horizontal line passing through (0, 1). The reflection of a point (x, y) across this line will have the same x-coordinate but a y-coordinate that is the same distance from the line y = 1 as the original point, but in the opposite direction.

So, the y-coordinate of the reflected point B' will be:

y-coordinate of B' = 1 - (y-coordinate of B - 1)

y-coordinate of B' = 1 - (5 - 1) = -3

Therefore, the coordinates of B' are (-2, -3).

By answering the presented question, we may conclude that As a result, function the solution is y = x/3.

In mathematics, a function seems to be a link between two sets of numbers in which each member of the first set (known as the domain) corresponds to a specific member of the second set (called the range). In other words, a function takes input from one collection and creates output from another. The variable x has frequently been used to represent inputs, whereas the variable y has been used to represent outputs. A formula or a graph can be used to represent a function. For example, the formula y = 2x + 1 depicts a functional form in which each value of x generates a unique value of y.

A direct variation function has the formula y = kx, where k is the proportionality constant. We may utilise the supplied coordinates (-9, -3) and (-12, -4) to obtain k as follows:

(using the point (-9, -3)) -3 = k(-9)

-4 = k(-12) (using the coordinates -12, -4)

When we solve for k in both equations, we get:

k = -3/9 = -1/3 \sk = -4/-12 = 1/3

We made a mistake in one of the equations since the values of k are not the same. The first equation is clearly erroneous since it suggests k = -1/3, which is not the same as k = 1/3 from the second equation. As a result, the proper equation for the direct variation function is:

y = (1/3)x

As a result, the solution is y = x/3.

Answer: x= 137 degrees and y= 43 degrees

Step-by-step explanation: The opposite angles of a parallelogram are congruent (equal). ∠A = ∠C and∠D = ∠B.

x is 137 because the opposite angle is congruent.
y is 43 because a parallelogram is equal to 360 degrees, so we would subtract the angles we already know (137+137) from the 360 which leaves you with 86. Since opposite angle are the same you’d have to divide 86 to make it equal for both opposite sides. So 43 on y and its opposite angle.

Answer:

The size by which the shape is enlarged or reduced is called as its scale factor. It is used when we need to increase the size of a 2D shape, such as circle, triangle, square, rectangle, etc. The scale factor is 2:5, this means that 2 feet at the original is 5 feet in new.

Therefore the new base is 18 x 5/2 = 45 feet

The new height  = 7 x 5/2 = 17.5 feet

The area of a triangle = ½ base x height

There's the area of the old deck = 1/2 × 18 × 7 = 63 square feet the area of the new deck = 1/2 × 45 × 17.5 = 393.75 square feet.

The scale factor = 2/5 = 1/2.5

The area of the given figure consisting of rectangle and triangles is 51.5 square feet.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area. Square units like cm² and m² are used to measure area.

We must first calculate the areas of each form in the figure in order to obtain the total area.

Let's start by calculating the rectangle's area:

Area = length x width

Area = 11ft x 4ft

Area = 44ft²

The area of the two right triangles should now be determined.

Triangle 1:

Area = (base x height) / 2

Area = (2ft x 3ft) / 2

Area = 3ft²

Triangle 2:

Area = (base x height) / 2

Area = (3ft x 3ft) / 2

Area = 4.5ft²

The total area of the figure can now be calculated by adding the areas of the three shapes:

Total Area = Area of Rectangle + Area of Triangle 1 + Area of Triangle 2

Total Area = 44ft² + 3ft² + 4.5ft²

Total Area = 51.5ft²

What is null hypothesis's?

A null hypothesis is a statement or assumption that there is no significant difference or relationship between two or more variables or groups. In statistical hypothesis testing, the null hypothesis is usually denoted as H0 and is tested against an alternative hypothesis (Ha), which is the hypothesis that there is a significant difference or relationship between the variables or groups being studied.

According to the question:
(a) The null hypothesis is that there is no significant difference in the average amount of money spent per day between the two groups. The alternative hypothesis is that there is a significant difference in the average amount of money spent per day between the two groups.

Since we are not given any information about the direction of the difference, we will use a two-tailed test. The appropriate test to use in this situation is the two-sample t-test.

(b) To find the critical z-value, we first need to calculate the degrees of freedom for the test:

df = (n1 + n2 - 2) = (25 + 27 - 2) = 50

Using a significance level of 0.01, we find the critical z-value using a z-table or calculator:

Critical z-value = ±2.576

(c) To find the test value, we will first calculate the pooled standard deviation using the formula:

[tex]sp = \sqrt{((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2)}[/tex]

where s1 and s2 are the sample standard deviations and n1 and n2 are the sample sizes. Substituting the given values, we get:

[tex]sp = \sqrt{((24 * 5.3^2) + (26 * 6.8^2)) / 50} = 6.083[/tex]

Next, we calculate the t-value using the formula:

[tex]t = (x1 - x2) / (sp * \sqrt{1/n1 + 1/n2})[/tex]

where x1 and x2 are the sample means. Substituting the given values, we get:

[tex]t = (38.6 - 37.4) / (6.083 * \sqrt{1/25 + 1/27}) = 1.213[/tex]

Since the absolute value of the test value is less than the critical z-value, we fail to reject the null hypothesis. Therefore, we cannot conclude that there is a significant difference in the average amount of money spent per day between the two groups.
