Using the arithmetic sequence formula we know that the 14 term of the given sequence is 41.

An arithmetic series is one that has the following formula: a, a + d, a + 2d, a + 3d, a + 4d,...

The common difference of the sequence is d, and the number an is the first term.

An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d.

So, we have the sequence:

2, 5, 8, 11, 14

Common difference = 5 - 2 = 3

Then, the formual is:

aₙ = a + (n - 1)d

Then, insert values:

aₙ = a + (n - 1)d

a₁₄ = 2 + (14 - 1)3
a₁₄ = 2 + (13)3

a₁₄ = 2 + 39

a₁₄ = 41

The value of the unknown term in the given triangle that satisfied the relation of angle bisector theorem is 9.

What about angle bisector theorem?

The angle bisector theorem is a fundamental theorem in geometry that relates the lengths of the sides of a triangle to the lengths of the segments formed by the intersection of an angle bisector with the opposite side.

Specifically, the angle bisector theorem states that the length of the segment of the side of a triangle that is opposite to the bisected angle is proportional to the lengths of the other two sides of the triangle. More precisely, if AD is the bisector of angle BAC in triangle ABC, then:

BD/DC = AB/AC

where BD and DC are the lengths of the segments of side BC that are adjacent to point A, and AB and AC are the lengths of the sides opposite to angles B and C, respectively.

This theorem is useful in many geometric constructions and proofs, and can be applied to various problems involving triangles and their properties.

According to the given information:

Using the concept of height and distance we have that,

[tex]tan(y) = \frac{4}{12} \\\\tan(2y) = \frac{2tany}{1-(tany)^{2} }[/tex]

In the given figure of triangle the value of tan(2y) = [tex]\frac{4+x}{12}[/tex]

So, when we correlate all of them we have that

[tex]\frac{2*\frac{4}{12} }{1-(\frac{4}{12}) ^{2} } = \frac{4+x}{12} \\\\x = 5[/tex]

1. The Similarity between AD and AB is that AD is half the length of AB.

2. The areas of triangles ACD and BDC are equal.

3. We can say that if AC is the longest side, then CB is the shortest side

4. False, The relationship between AD and AB is that AD is half the length of AB.

A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle. The sum of all three angles of the triangle is equal to 180 degrees.

1) Since D is the midpoint of AB, we know that AD and DB have the same length. Therefore, we can say that:

AD = DB

Substituting AB for AD + DB, we can simplify to:

AB = AD + AD

or

AB = 2AD

So, the relationship between AD and AB is that AD is half the length of AB.

2) The areas of triangles ACD and BDC are equal, and we can write:

Area of ACD = (1/2) * AC * AD

Area of BDC = (1/2) * BC * DB

Since AD = DB, we can substitute and get:

Area of BDC = (1/2) * BC * AD

So, we can see that the areas of ACD and BDC are equal, and their bases AD and DB have the same length. Therefore, triangles ACD and BDC are equal in area and shape (they are congruent).

3) we can say that if AC is the longest side, then CB is the shortest side

At the moment when the rockets are at the same height, their height is approximately -223.34 meters. Note that this negative value indicates that they are both below the ground level.

How to find moment?

To find the moment when the rockets are at the same height, we need to set the two height functions equal to each other and solve for x:

-3.4x²- 64 = -3.4x² - 25x - 45

Simplifying and rearranging:

0 = 25x + 19

x = -19/25

So the rockets are at the same height after -19/25 seconds, or about 0.76 seconds.

To find the height at this moment, we can plug this value of x into either of the height functions. Let's use Ryan's function:

h(-19/25) = -3.4(-19/25)²- 64

= -3.4(361/625) - 64

= -223.34

So at the moment when the rockets are at the same height, their height is approximately -223.34 meters. Note that this negative value indicates that they are both below the ground level.

 the income tax payable on a salary of Birr 5200 is Birr 320.

In Ethiopia, income tax is calculated based on a progressive tax system where the tax rate increases as the taxable income increases. The formula for calculating income tax on monthly salary is as follows:

Taxable income = Gross monthly salary - Deductions

Tax payable = Tax rate * (Taxable income - Tax threshold) - Allowances

Where:

1. Gross monthly salary: Total salary before any deductions.

2. Deductions: Includes mandatory deductions such as employee social security contributions, pension contributions, and other authorized deductions.

3. Taxable income: Gross monthly salary minus deductions.

4. Tax rate: The percentage of tax applicable to the taxable income based on the tax bracket.

5. Tax threshold: The minimum amount of taxable income before tax is applicable.

6. Allowances: Includes authorized tax deductions such as dependant's allowance and other authorized allowances.

To calculate the income tax on a salary of Birr 5200, we need to determine the taxable income first. Let's assume that the gross monthly salary is Birr 5200, and there are no deductions.

Taxable income = Birr 5200 - 0 = Birr 5200

Next, we need to determine the tax rate applicable to this taxable income based on the tax bracket. For the taxable income range of Birr 5251 to 7800, the tax rate is 10%. Therefore, the tax rate applicable to Birr 5200 is 10%.

Tax rate = 10%

Now, we need to determine the tax threshold and the allowances applicable to this taxable income. Let's assume that the tax threshold is Birr 2000, and there are no allowances.

Tax threshold = Birr 2000

Allowances = 0

Using the formula mentioned earlier, we can calculate the income tax payable as follows:

Tax payable = 10% * (Birr 5200 - Birr 2000) - 0

Tax payable = Birr 320

Therefore, the income tax payable on a salary of Birr 5200 is Birr 320.

To derive the formula to calculate income tax on Birr x, we can use the same formula mentioned earlier. We can express the formula in terms of x as follows:

Taxable income = x - Deductions

Tax payable = Tax rate * (Taxable income - Tax threshold) - Allowances

Where:

1. x: Gross monthly salary.

2. Deductions: Includes mandatory deductions such as employee social security contributions, pension contributions, and other authorized deductions.

3. Taxable income: Gross monthly salary minus deductions.

4. Tax rate: The percentage of tax applicable to the taxable income based on the tax bracket.

5. Tax threshold: The minimum amount of taxable income before tax is applicable.

6. Allowances: Includes authorized tax deductions such as dependant's allowance and other authorized allowances.

We can use this formula to calculate the income tax payable on any salary falling within the Birr 5251 to 7800 taxable income range.

In conclusion, income tax in Ethiopia is calculated based on a progressive tax system, where the tax rate increases as the taxable income increases. To calculate income tax on a salary of Birr 5200, we need to determine the taxable income, tax rate, tax threshold, and allowances applicable to that salary. We can use the same formula to calculate income tax on any salary within the Birr 5251 to 7800 taxable income range.

The quadratic function representing the area of ​​the photo and the frame is A(x) =  1.7x²+ 16.2x + 36

When calculating a rectangle's area, we multiply the length by the width of the rectangle.

Area of rectangle = length × breadth

To represent the  photo and frame area, we need to add the photo area  to the frame area. Since the frame is 3 inches wide on all sides, the photo dimensions are reduced by 6 inches in both  length and  width. Therefore the length of the photo with the frame is (x 6) inches and the width is (1.7 x 6) inches. Thus, the area of ​​the photo and the frame can be represented by a quadratic function:

A(x) = (x 6) (1.7 x 6)

Expanding this expression, we get:

A(x) =  1.7x² + 16.2x + 36

So the quadratic function representing the area of ​​the photo and the frame is A(x) =  1.7x²+ 16.2x + 36

Using the point-slope form of the equation of a line. the x-intercept of the line is [tex]-2.5[/tex].

To find the x-intercept of the line, we need to find the point where the line intersects the x-axis. We know that the y-coordinate of this point is zero, because it is on the x-axis. Let's call the x-coordinate of this point "x".

We also know that the line passes through the point (-2.5,0), because it is 2.5 units to the left of the origin. Using the point-slope form of the equation of a line, we can write the equation of the line as:

[tex]y - 0 = m(x - (-2.5))[/tex]

where m is the slope of the line. To find the slope, we can use the fact that the line passes through the point  [tex](0,1)[/tex] and [tex](-2.5,0)[/tex]:

[tex]m = (1 - 0) / (0 - (-2.5)) = 1 / 2.5 = 0.4[/tex]

The answer of the given question based on the Angular speed is (a) the angular speed of a point on Mars' equator is π/2 radians per day. (b) the linear speed of a point on the equator of Mars is approximately 889.33 miles per day.

Linear speed, also known as tangential speed, is the distance traveled by an object in a straight line per unit of time. It is the speed at which an object is moving along its path, tangent to the path at any given point. Linear speed is calculated by dividing the distance traveled by the time taken to travel that distance. The units of linear speed are typically expressed in meters per second (m/s), miles per hour (mph), or kilometers per hour (km/h), depending on the system of measurement used.

(a) The angular speed of a point on Mars' equator is the angle (in radians) that a point on the equator sweeps out as Mars rotates on its axis. Since Mars completes one rotation every 24 hours, the angular speed is:

angular speed =(2πradians)/ (24 hours)= π/12radians per hour

To find the angular speed in radians per day, we need to multiply by the number of hours in a day:

angular speed = (π/12 radians per hour) * (24 hours per day) = π/2 radians per day

Therefore, the angular speed of a point on Mars' equator is π/2 radians per day.

(b) The linear speed of a point on the equator is the distance traveled by a point on the equator in a certain amount of time. The distance traveled by a point on the equator in one rotation is equal to the circumference of the circle with a diameter of miles, which is:

C = πd = π(6794) ≈ 21343.98 miles

Since Mars rotates once every 24 hours, a point on the equator travels the circumference of the circle in 24 hours. Therefore, the linear speed of a point on the equator in miles per day is:

v = C/24 ≈ 889.33 miles/day

So the linear speed of a point on the equator of Mars is approximately 889.33 miles per day.

Answer: The probability that both televisions work is approximately 0.746, or 74.6%.

Step-by-step explanation:

To calculate the probability that both televisions work, we need to find the probability of selecting a working television, and then multiply that by the probability of selecting another working television from the remaining televisions.

Since 2 out of the 14 televisions are defective, that means there are 12 working televisions out of 14. So the probability of selecting a working television on the first draw is 12/14.

After the first television is selected, there will be 13 televisions left, with 11 working televisions. So the probability of selecting a second working television is 11/13.

Therefore, the probability that both televisions work is:

(12/14) x (11/13) = 0.746

So the probability that both televisions work is approximately 0.746, or 74.6%.

To calculate the probability that at least one of the two televisions does not work, we can use the complement rule. The complement of the event "both televisions work" is the event "at least one television does not work."

So, the probability that at least one television does not work is:

1 - 0.746 = 0.254

So the probability that at least one television does not work is approximately 0.254, or 25.4%.

Answer:

0.60, 0.40

Step-by-step explanation:

The probability that a television works is 11/14. The probability that a television is

defective is 3/14.

The probability that the first TV works and the second works is

[tex]\frac{11}{14}[/tex]×[tex]\frac{10}{13}[/tex]

(If the first selected TV works, the total number of televisions left is 13, and the

the number of working TV is 10).

Answer: 0.60.

The event that at least one of the two televisions does not work is the

opposite of the event ‘both TV work’. So the probability of at least one of the

two televisions does not work is

1- Pr (both works)= 1 − 11/14 ∙ 10/13 = 0.40.

Answer: 0.40.

To find the greatest number of plants that can be put in one row, we need to find the greatest common factor (GCF) of 45, 81, and 63.

First, we can find the prime factorization of each number:

45 = 3 x 3 x 5

81 = 3 x 3 x 3 x 3

63 = 3 x 3 x 7

Then, we can identify the common factors:

The factors of 45 are 3 and 5

The factors of 81 are 3 and 3

The factors of 63 are 3 and 3

The greatest common factor is the product of the common factors raised to their lowest power:

GCF = 3^2 x 5 x 7 = 315

The rate per hour for the ferris wheel is 144 people per hour.

Your pay for each hour of labour is expressed as an hourly rate. You might need to estimate your income for other applications or modify your personal budget after comparing the hourly and salaried pay rates.

The ferris wheel can accommodate 60 people in 25 minutes.

To find out how many people could ride the ferris wheel in 4 hours, we need to convert 4 hours to minutes, since the given rate is in minutes.

1 hour = 60 minutes

4 hours = 4 x 60 minutes = 240 minutes

So, in 4 hours, the ferris wheel could accommodate 240/25 = 9.6 (rounded to the nearest whole number) cycles of 60 people.

The total number of people that could ride the ferris wheel in 4 hours would be 9.6 x 60 = 576 people.
