The angle of elevation of the point T on the top of the pole from the point A on the level ground, obtained using Pythagorean Theorem and the relationship between similar triangles is about 39.3°.

What are similar triangles?

Similar triangles are triangles that have the same shape (the sizes may be different) and in which the ratio of the corresponding sides are equivalent.

The triangles ΔXBA, ΔXAC, and ΔABC are right triangles, such that the angles, ∠ABX in triangle ΔXBA is congruent to triangle ∠CAX in triangle ΔXAC, and ∠ABC in ΔABC.

The 90° angle in the right triangles are congruent (All 90° angle are congruent), therefore;

ΔXBA ~ ΔXAC ~ ΔABC by AA (Angle-Angle), similarity postulate

The length of the hypotenuse in the right triangle, ΔABC, [tex]\overline{BC}[/tex], can be obtained using Pythagorean Theorem as follows;

[tex]\overline{BC}[/tex]² = 14² + 25² = 821

[tex]\overline{BC}[/tex] = √(821)

[tex]\overline{BC}[/tex]/[tex]\overline{AC}[/tex] = [tex]\overline{AB}[/tex]/[tex]\overline{AX}[/tex]

√(821)/25 = 14/[tex]\overline{AX}[/tex]

[tex]\overline{AX}[/tex] = 25 × (14/(√(821)) = 350/(√(821))

Let θ represent the angle of T from A, we get;

tan(θ) = 10/(350/(√(821)))

θ = arctan(10/(350/(√(821)))) ≈ 39.3°

The angle of elevation of T from A is about 39.3°

Answers

Solution for the variable 'y' is y = (x - x² + 8)/5  

Solving an equation:

To solve the following equation we need to isolate the variable 'y' this can be done by adding or subtracting the same integer on both sides

Similarly, multiply or divide with the same integer on both sides. Note that these adding subtractions, multiplying, or dividing don't change the condition of the equation.

Here we have

5y+x² = x+8  

To solve the above equation we need to isolate 'y' as follows

=> 5y+x² = x+8    

Subtract x² from both sides

=> 5y + x² - x² = x + 8

=> 5y = x - x²+ 8

Divide by '5' on both sides

=> 5y/5 = (x - x² + 8)/5

=> y = (x - x² + 8)/5

A taxi journey takes the passenger to a destination 8 km south and 3 kn west of its starting point. Find the distance and bearing of the destination from its starting point.

Using trigonometry.

Answers

Answer: We can use trigonometry to solve this problem.

First, let's draw a diagram to represent the situation:

           |

           |

           | 8 km

           |

           |

   --------X---------

           | 3 km

           |

           |

           |

           |

The starting point is at the X, and the destination is 8 km south and 3 km west of the starting point.

To find the distance and bearing of the destination from the starting point, we can use the Pythagorean theorem and trigonometric functions.

The distance between the starting point and destination is the hypotenuse of a right triangle with legs of length 8 km (south) and 3 km (west). So we can use the Pythagorean theorem:

distance = √(8² + 3²) ≈ 8.6 km

To find the bearing (direction) of the destination from the starting point, we can use trigonometry. The bearing is the angle between the line connecting the starting point and destination and the line pointing due north.

We can use the tangent function to find this angle:

tan(θ) = opposite/adjacent = 3/8

θ = tan⁻¹(3/8) ≈ 20.56°

So the bearing of the destination from the starting point is approximately 20.56° west of due south.

Therefore, the distance of the destination from the starting point is approximately 8.6 km and the bearing of the destination from the starting point is approximately 20.56° west of due south.

Answers

To begin with, let us define the system of ordinary differential equations for the benzene ring:

[tex]d^2θj/dt^2 + αdθj/dt + ω^2(θj−1−2θj+θj+1) = F cos(γt)[/tex]

Verification of time-independent particular solution:

When α = 0, the system becomes time-independent, and the equation reduces to:

[tex]θj'' + ω^2(θj−1−2θj+θj+1) = F cos(γt)[/tex]

We can assume a time-independent solution of the form θj = Aj, where A is a constant. Substituting this into the equation, we get:

[tex]Aω^2(j-1 + j + j+1) = F cos(γt)[/tex]

By simplifying

3Aω^2j = F cos(γt)

Therefore, the time-independent particular solution is θj = (F/3ω^2)cos(γt) + Aj, where A is a constant.

Eigenvectors and eigenvalues:

predicting the solution θj = Aj e^(iλt),we can integrate into an equation

[tex]−A(λ^2+αλ+ω^2)e^(iλt) + ω^2(e^(iλt)(A(j−1) + A(j+1)) + 2A(j)e^(iλt)) = F cos(γt)e^(iλt)[/tex]

Dividing both sides by e^(iλt), we get:

[tex]−A(λ^2+αλ+ω^2) + ω^2(A(j−1) + A(j+1) + 2A(j)) = Fcos(γt)[/tex]

Simplifying, we get:

[tex](2ω^2A − λ^2A) + ω^2(A(j−1) + A(j+1)) = F cos(γt) + αλA[/tex]

What is the perimeter of a regular hexagon with area of 96 square ruut to 3cm square

Answers

the perimeter of the regular hexagon is 48 cm.

A regular hexagon is a polygon with six sides, and each side has the same length. The formula to calculate the perimeter of a regular hexagon is given as:

Perimeter = 6 × length of one side

To find the length of one side of the hexagon, we need to use the given information about the area. The formula for the area of a regular hexagon is given as:

Area = (3 × √3 × s^2)/2, where s is the length of one side of the hexagon.

We can use this formula to solve for the length of one side:

96 √3 = (3 × √3 × s^2)/2

Simplifying this equation, we get:

s^2 = (2 × 96 √3)/(3 × √3)

s^2 = 64

s = 8 cm

Now that we know the length of one side of the hexagon, we can use the formula for perimeter to find the total perimeter:

Perimeter = 6 × 8 cm

Perimeter = 48 cm

Therefore, the perimeter of the regular hexagon is 48 cm.

In a regular hexagon, all six angles are equal, each measuring 120 degrees. It is a symmetrical shape, meaning that it has six lines of symmetry. The regular hexagon is a common shape in nature and architecture, and it is often used in geometry problems because of its regularity and symmetry. The hexagon is also the basis for the hexagonal lattice structure, which is a common pattern in crystals and other materials.

Hence, in answering the stated question, we may say that 128.57 quadrilateral degrees is the angle C. D is equal to 171.42 degrees.

what is quadrilateral?

A quadrilateral in geometry is a four-sided polygon with outer walls and four corners. The term comes from the Roman terms quadri and lead people to make bad (meaning "side"). A rectangle is a two-dimensional shape with sidewalls, four vertices, and four corners. Concave and convex surfaces are usually divided into two types. Trapezoids, parallelograms, rectangular, rhombuses, and squares are also subclasses of convex quadrilaterals. A rectangle is an a double form that has four straight sides. Parallelograms, trapezoids, triangles, kites, squares, etc rhombuses are examples of quadrilaterals.

The total of a quadrilateral's internal angles equals 360 degrees.

The four inner angles of the quadrilateral ABCD are denoted as follows:

A-angle = 3x

B angle = 4x

Angle C = 5(3x) = 15x (since it is 5 times angle A)

Angle D = 5(4x) = 20x (since angle B is five times larger).

3x + 4x + 15x + 20x = 42x is the sum of these four angles.

3x + 4x + 15x + 20x = 360

42x = 360

x = 8.57 (rounded to two places) (rounded to two places)

Angle A = 3x + 3(8.57) = 25.71°

Angle B = 4x + 4(8.57) = 34.28°

Angle C = 15x + 15(8.57) = 128.57

D = 20x = 20(8.57) = 171.42 degree angle

As a result, the quadrilateral's internal angles are:

A angle of 25.71 degrees

34.28 degrees is the angle B.

128.57 degrees is the angle C.

D is equal to 171.42 degrees.

Suppose a county’s recent health report gives a pet allergy prevalence of 0.13 for kids.

The probability that the test gives a positive result when a child really does not have a pet allergy is 0.06. The probability that the test gives a negative result when a child really does have a pet allergy is 0.12. The tree diagram shows the possible outcomes with the associated probabilities.
What is the probability of an incorrect test result? Give your answer as a decimal precise to two decimal places.

Answers

Answer: To calculate the probability of an incorrect test result, we need to consider two cases:

1. The test gives a positive result when the child does not have a pet allergy (false positive).

2. The test gives a negative result when the child does have a pet allergy (false negative).

The probability of a false positive is given as 0.06, which means that out of 100 children who do not have a pet allergy, 6 will test positive for it. The probability of a false negative is given as 0.12, which means that out of 100 children who do have a pet allergy, 12 will test negative for it.

To calculate the probability of an incorrect test result, we can add the probabilities of these two cases:

Probability of incorrect test result = Probability of false positive + Probability of false negative

Probability of incorrect test result = 0.06 + 0.12

Probability of incorrect test result = 0.18

Therefore, the probability of an incorrect test result is 0.18, or 18% (rounded to two decimal places).

The expected number of times player A plays a turn is approximately 1.5.

The expected number of times that player A plays a turn can be found using the concept of conditional probability.What is probability?Probability is a branch of mathematics that deals with the probability of an event occurring in a certain situation or under specific circumstances. The total probability of any occurrence is always between 0 and 1. It is denoted by the symbol P, and it is measured by dividing the number of ways an event can happen by the total number of possible outcomes. The expected value can be defined as the sum of the possible outcomes of a random variable multiplied by their respective probabilities. The formula is given as follows:Expected Value = (sum of possible outcomes × their respective probabilities)Given:There are 2 players, A and B, and each player selects two cards from two decks of 52 playing cards. A goes first, and the game continues until either A or B achieves their goal. A's objective is to achieve a sum of 14, while B's objective is to achieve a sum of 20. Assume that all face cards are worth 10 points.

Find the expected number of turns A will play.Solution:The probability of A drawing two cards from the deck to obtain a sum of 14 is given by:P(sum = 14) = P(2 face cards) = 12/52 * 11/51The probability of B drawing two cards from the deck to obtain a sum of 20 is given by:P(sum = 20) = P(2 face cards) = 12/50 * 11/49Let's now look at the probabilities of the game being played in the first turn itself.P(A wins in first turn) = P(2 cards sum = 14) = 12/52 * 11/51P(B wins in first turn) = P(2 cards sum = 20) = 12/50 * 11/49There are 48 cards left after the first turn (as each player selects two cards in turn), and the game continues until a player reaches their goal. Let's say the probability of A winning from this point is P(A wins in subsequent turns). Then we can write:P(A wins) = P(A wins in first turn) + P(A wins in subsequent turns)Similarly,P(B wins) = P(B wins in first turn) + P(B wins in subsequent turns)The expected number of turns A plays can be obtained using the concept of conditional probability as follows:Let P(A) = probability of A winning = P(A wins)Let P(B) = probability of B winning = P(B wins)Let P(D) = probability of a draw or the game continuing indefinitely = 1 - P(A) - P(B)

Then the expected number of times that player A plays a turn is given by:Expected value = (1 × P(D)) + (1 × P(A)) + (1 + Expected value) × P(B)Substituting the values, we get:Expected value = 1 + P(B) × Expected valueDividing by P(B), we get:Expected value / P(B) = 1 + Expected valueSolving for Expected value, we get:Expected value = P(B) / (1 - P(B))P(B) can be calculated as follows:P(B) = P(B wins in first turn) + P(B wins in subsequent turns) = 12/50 * 11/49 + P(A wins in subsequent turns)P(A wins in subsequent turns) can be found using the concept of recursion, which is as follows:P(A wins in subsequent turns) = P(A wins on A's first turn) + (1 - P(A wins on A's first turn)) × P(B wins)P(A wins on A's first turn) = P(2 cards sum = 14) = 12/52 * 11/51Hence,P(A wins in subsequent turns) = 12/52 * 11/51 + (1 - 12/52 * 11/51) × (12/50 * 11/49) = 0.0642Using the above values, we can find the value of P(B):P(B) = 12/50 * 11/49 + 0.0642 = 0.1313Therefore,Expected value = P(B) / (1 - P(B)) = 0.1313 / (1 - 0.1313) ≈ 0.152 ≈ 1.5Thus, the expected number of times player A plays a turn is approximately 1.5.

Ratio of boys to girls is 4:5. How many boys are there if there are 488 girls

Answers

As per the given ratio, the number of boys is 392.

The given ratio of boys to girls is 4:5. This means that for every 4 boys, there are 5 girls. We can express this ratio mathematically as:

Boys/Girls = 4/5

We can use this ratio to find out how many boys are there if there are 488 girls.

Let's assume that the total number of children is "x".

Boys + Girls = x

We know that the ratio of boys to girls is 4:5, which means that the total number of parts in the ratio is 4+5=9. We can express this mathematically as:

Number of boys = (4/9) x x

Number of girls = (5/9) x x

We are given that there are 488 girls in the group, so we can substitute this value into the equation for the number of girls:

(5/9) x x = 488

To solve for "x", we can multiply both sides of the equation by 9/5:

x = 488 x (9/5)

x = 878.4

Since we cannot have a fraction of a child, we can round the answer to the nearest whole number. Therefore, there are 878 children in the group. To find out how many boys there are, we can substitute this value into the equation for the number of boys:

Number of boys = (4/9) x 878

Number of boys = 392

Therefore, there are 392 boys in the group if there are 488 girls and the ratio of boys to girls is 4:5.

Where X must be a positive number smaller than one, now we can solve it:

we know that in the class we have 45 students, and 4/5 of those students have dogs, so the number of students that have a dog as a pet is:

N = 45*(4/5) = 36

And we know that X of those 36 students also have a cat, so the number of students that have a dog and a cat is:

M = 36*X

now, we do not have, suppose that the value of X is 1/2 ("1/2 of the students who have a dog also have a cat")

Let amy works 'x hours' in each week. So, her working rate is x/7 hours/day. As we know very well that weekend consists two days ( Saturday and Sunday). So, she will make extra work each week = extra work in weekend ( 2 days)

The extra work that she will do in weekend or each week= 2(x/7) = 2x/7 hours = 6 hours

Now, The extra work hours that she make in seven weeks = Multiplication of 7 by the extra work hours that she make in each week

= 7(6) hours = 42 hours

Hence, required value of hours is 42 ( that is double of her working hours in week days).

whats the probability for a quarter to land on tails and a rolling die to land on two

Answers

The probability that a quarter lands on tail and a rolling die land on 2 is 1/12

What is probability?

A probability is a number that reflects the likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

Probability = sample space /total outcome

A quarter has two faces, the head and the tail. Therefore the probability for a quarter to land on tail = 1/2

A die has 6 faces , labelled 1, 2,3,4, 5,6.

The probability for a die to land on 2 = 1/6

Therefore the probability for a quarter to land on tail and a die to land on 2 = 1/2 × 1/6 = 1/12

Sally invests $10,000 into a new bank account at 8. 4% interest compounded monthly. How much money will Sally have in the account in 30 years to the nearest cent?

Answers

As per the compound interest, Sally have the amount in the account in 30 years is $100,620.95

The formula for compound interest is given as:

A = P(1 + r/n)ˣⁿ

Where A is the amount of money in the account after t years, P is the initial investment, r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year, and x is the number of years.

In this case, we have P = $10,000, r = 0.084 (8.4% expressed as a decimal), n = 12 (monthly compounding), and x = 30. Substituting these values into the formula, we get:

A = $10,000(1 + 0.084/12)¹²ˣ³⁰

A = $10,000(1.007)³⁶⁰

A = $10,000(10.062)

A = $100,620.95

Therefore, after 30 years, Sally will have $100,620.95 in her bank account, to the nearest cent. This calculation illustrates the power of compound interest, as Sally's initial investment has grown by more than tenfold due to the compounding effect over 30 years.

Mrs Burn buys a washing machine that costs R3 999 at a discount of 6%. Calculate the discount on washing machine and the amount she has to pay.​

Answers

Answer:

Discount Rs 239.94= 240

She has to pay 3659

Step-by-step explanation:

6 % of 3999=239.94 or 240

She will get the discount of 240 rupees.

She has to pay other amount beside the discount.

The price of machine is 3999.

The price she has to pay after discount= actual price- discount.

So discounted price is Rs3659

Answer: If the original price of the washing machine is R3 999 and it is discounted by 6%, then the discount amount can be calculated as follows:

Discount amount = 6% of R3 999

= 0.06 x R3 999

= R239.94

Therefore, Mrs Burn will receive a discount of R239.94 on the washing machine.

The amount she has to pay can be calculated as follows:

Amount to be paid = Original price - Discount amount

= R3 999 - R239.94

= R3 759.06

Therefore, Mrs Burn has to pay R3 759.06 for the washing machine after the 6% discount.

The length οf the parallelοgram is 6.15 cm.

What is perimeter?  

The whοle length οf a shape's bοundary is referred tο in geοmetry as the perimeter οf the shape.

Adding the lengths οf all the sides and edges that surrοund a fοrm yields its perimeter. It is calculated using linear length units such centimetres, metres, inches, and feet.

Here the given Perimeter οf parallelοgram = 20.5 cm.

Side  = 4.1 cm

Nοw perimeter οf parallelοgram = 2(a+b) unit

=> 20.5 = 2(a+4.1)

The given story has a sampling type known as: voluntary response sampling.

What type of sampling was used?

Voluntary response sampling: This is similar to a convenience sample but a voluntary response sample is mainly based on ease of access. Instead of the researcher choosing participants and directly contacting them, people volunteer themselves (e.g. by responding to a public online survey).

For example, a person being called in a radio show poll might have powerful opinions over a topic in any direction. In a voluntary random sample, chooses themselves by answering a common appeal.  These samples are unreliable because they are bias, hence the result is usually biased.

In this question, Mrs. Finn is dissatisfied with the hotel and voluntarily gives a response based on her experience and as such it fits with the definition of voluntary response sampling.

Answer:

Step-by-step explanation:

a= first form a equation

lets call the cheese c and the buns b

2c+3b=10

c=2+b

3c+4b=12

now its a simultaneous equation

2c+3b=10    x3

3c+4b=12    x2

6c+9b=30

6c+8b=24

1b=6

b=6

now substitute it in to 2c+3b=10

2c+18=10

2c+-8

so c=$4

b= 56 difference 14

56/2=28

28-7
