Right Triangle Trigonometry Im Going To Be Honest I Do Not Know How To Solve This.

Answers

Answer 1

The exact values of a and b are [tex]5[/tex] and [tex]5\sqrt{3}[/tex]  respectively. Thus, option A is correct.

What is Sine?

A right-angled triangle's sine function is defined as the ratio of the opposite side's length to the hypotenuse's length.

Sin α= Opposite/ Hypotenuse

In trigonometry, the cos is defined as the ratio of the length of the adjacent side to that of the longest side i.e. the hypotenuse

cos α = Adjacent Side/Hypotenuse

In ΔACB,

AB is the hypotenuse, AB=10

Sin 30=BC/AB

[tex]1/2 = a/10[/tex]

Multiply both sides by 10:

[tex]a = 10 \times (1/2) = 5[/tex]

Therefore, the value of a is 5.

Cos 30=AC/AB

[tex]\sqrt3/2 = b/10[/tex]

Multiply both sides by 10:

[tex]b = 10 \times \frac{\sqrt{3}}{2} = 5\sqrt3[/tex]

Therefore, the value of b is 5√3.

Answer 2

The exact value of a and b is 5 and [tex]5\sqrt{3}[/tex] which means option a is correct.

How to find the trigonometric ratio for a right-angle triangle?

The triangle is a right-angle triangle.

The hypotenuse is given = 10

By applying the trigonometric ratios we can find the value of a and b.

Apply sine formulae to find value a.

[tex]sin30 = \frac{opposite side of the angle 30}{hypotenuse} \\sin30 = \frac{a}{10} \\\frac{1}{2} = \frac{a}{10} \\2a = 10\\a = 5[/tex]

Apply cosine formulae to find value b.

[tex]cos30 = \frac{adjacent side of the angle 30}{hypotenuse} \\cos30 = \frac{b}{10} \\\frac{\sqrt{3} }{2} = \frac{a}{10} \\2a = 10 *\sqrt{3} \\a = 5\sqrt{3}[/tex]

Therefore the values of a and b are 5 and [tex]5\sqrt{3}[/tex]

ow must the units be set up in order to get from the number of eggs used to make a certain number of cookies to the number of eggs needed to make some other number of cookies?

Answers

To get from the number of eggs used to make a certain number of cookies to the number of eggs needed to make some other number of cookies, you would use a proportional relationship.

Let's say x represents the number of eggs used to make a certain number of cookies, y represents the number of cookies made, and z represents the number of eggs needed to make some other number of cookies.

Then, we can set up the proportion:

x eggs / y cookies = z eggs / (some other number of cookies)

We can then solve for z by cross-multiplying:

z eggs = x eggs * (some other number of cookies) / y cookies

This formula tells us how many eggs are needed to make the specified number of cookies, based on the number of eggs used and the number of cookies originally made.

Over a period of one week, the Dow Jones Industrial Average (DJIA) did the following: On Monday the DJIA went down by 3.2%, on Tuesday it went up by 11.2%, on Wednesday it went up by 0.7%, on Thursday it went down by 4.8%, and on Friday it went down by 9.4%. Find the percentage increase/decrease of the DJIA over the week. Round your answer to the nearest hundredth of a percentage.

Answers

The percentage increase/decrease of the DJIA over the week is a decrease of 6.53%.

What is percentage?

Percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%".

A decreased percentage refers to the amount or rate by which a quantity or value has decreased from its original or initial value, expressed as a percentage of the original value.

According to given information:

To find the percentage increase/decrease of the DJIA over the week, we need to calculate the overall change in the index and express it as a percentage of the initial value.

Let's assume that the DJIA started the week at a value of 100. Then, the following changes would occur:

On Monday, it went down by 3.2%, so its value decreased to 96.8.

On Tuesday, it went up by 11.2%, so its value increased by 11.2% of 96.8, or 10.82, to reach 107.62.

On Wednesday, it went up by 0.7%, so its value increased by 0.7% of 107.62, or 0.75, to reach 108.37.

On Thursday, it went down by 4.8%, so its value decreased by 4.8% of 108.37, or 5.20, to reach 103.17.

On Friday, it went down by 9.4%, so its value decreased by 9.4% of 103.17, or 9.70, to reach 93.47.

Therefore, over the week, the DJIA decreased by 6.53% (from 100 to 93.47).

Rounding this to the nearest hundredth of a percentage, we get a decrease of 6.53%.

So, the percentage increase/decrease of the DJIA over the week is a decrease of 6.53%.

One real-world situation that could be modeled by the arithmetic sequence f(n) = 100 + 25n, for n ≥ 1, is the cost of a monthly subscription service for an online course.

What is Arithmetic Sequence?  

An arithmetic sequence is a sequence of numbers where each term is found by adding or subtracting a constant value from the previous term. The constant value is called the common difference and determines the rate at which the sequence increases or decreases.

One real-world situation that could be modeled by the arithmetic sequence f(n) = 100 + 25n, for n ≥ 1, is the cost of a monthly subscription service for an online course.

Assuming that the initial cost of the service is $100 and the subscription fee increases by $25 every month, then the formula

=> f(n) = 100 + 25n

It can be used to calculate the cost of the subscription for any given month n.

For example, the cost of the subscription for the 5th month would be

f(5) = 100 + 25(5) = $225.

Similarly, the cost of the subscription for the 10th month would be

f(10) = 100 + 25(10) = $350.

Answers

The probability is unlikely.

What is probability ?

A probability is a number that expresses the possibility or liability that a specific event will take place. Chances can be stated as proportions with a range of 0 to 1, or as probabilities with a range of 0 to 100.

                              Probability is a measure of how likely or likely-possible commodity is to be. For case, there's only one system to admit a head and there are a aggregate of two possible issues, hence the chance of flipping a coin and entering heads is 1 in 2.( a head or tail). P( heads) = 12 is what we write.

The value of the probability and the notation is given as

P(true) = 0.2

As a general rule of probability, we have

Range of probability value = 0 to 1 (inclusive)

Unlikely = less than 0.5

Equally likely and unlikely = 0.5

Likely = greater than 0.5

Using the above as a guide, we have the following:

The value of P(true) = 0.2 is less than 0.5

The better survey would be when the possibility of adults in favour of fee and not in favour of fee is same that is 50% each.

Explain about the unbiased survey:

Everything in surveys revolves around asking the appropriate questions in the right ways since they are meant to elicit feedback. Many polls purposefully and unintentionally ask one-sided questions.

An objective question attempts to avoid using leading language and is fact-based rather than judgmental.

Biased questionnaire items use word choice and sentence structure in a way that affects how respondents react. This is sometimes done on purpose. This usually happens as a result of inadequate survey planning and assessment.

Here are a few advices.

Check your questions to make sure they won't lead to bias in the responses.Make sure all potential responses are included in the answer choices.Ask as few and straightforward inquiries as you can.Don't ask participants to think more than is necessary.

Given query:

When adults left a library, they were asked if they would be open to paying a $100 yearly fee to support it. 80% of those polled indicated their support for the fee.The survey respondents came to the false conclusion that the fee is supported by 80% of the city's adult residents.

Answers

Thus, the perimeter of the regular nonagon with centre O is found as: 78.57 units.

Explain about the perimeter of regular polygon:

A closed, 2D structure with a finite number of line segments is referred to as a polygon. A polygon's number of vertices and its number of line segments are always identical. The perimeter of a closed figure is the sum of the lengths of its outermost sides. It is the sum of the lengths of a polygon's sides.

P = (Side length) x n

The apothem of each of the 9 isosceles triangles that make up the regular nonagon is 12 cm.

The angle at the circle's centre is 360/9 = 40º.

Hence, the sides of the regular nonagon, if the apothem of a isosceles triangles is 12 cm.

2*12 tan (40/2) = 8.73 cm

Then the perimeter:

P = 9 x 8.73

In ΔLMN, the measure of ∠N=90°, NM = 9, ML = 41, and LN = 40. What is the value of the cosine of ∠L to the nearest hundredth?

Answers

The value of the cosine of ∠L in triangle LMN is approximately 0.98 using Pythagorean Theorem.

To find the cosine of ∠L in triangle LMN, we first need to use the Pythagorean theorem to find the length of side LM, since only have the lengths of NM and LN:

[tex]LM^2 = LN^2 - NM^2\\LM^2 = 40^2 - 9^2\\LM^2 = 1521[/tex]

[tex]LM = \sqrt{1521}[/tex]

LM = 39

Now that we know the length of all three sides of the triangle, we can use the cosine rule to find the cosine of ∠L:

cos(L) = [tex](LM^2 + LN^2 - NM^2)[/tex] / (2 x LM x LN)

cos(L) = [tex](39^2 + 40^2 - 9^2)[/tex] / (2 x 39 x 40)

cos(L) = 0.975

Rounding to nearest hundredth:

cos(L) = 0.98

Therefore, the value of cosine of ∠L in triangle LMN is approximately 0.98.

The ratio of the neighbouring side to the hypotenuse is known as the cosine of an angle in a right triangle. As L is not a straight angle in this situation, its value must be determined using the cosine method. Whether a triangle is a right triangle or not, the cosine rule can be used to relate the lengths of its sides and angles.

if it cost $15 to fill a gas tank in 1995, how much would it have cost to fill the same tank in 2015?

Answers

If the cost to fill a gas tank in 1995 is $15 then the cost to fill a gas tank in 2015 is equals to the $31.25.

Price Index is a effective method of comparing relative change in the price of a quantity with respect to its price in a reference year. This year which we use as a reference is called the base year and price index is ratio of the price of a product in a year to its price in the base year ( expressed in percentage ).

The cost to fill a gas tank in 1995 = $15

Price index in 1995 = 100.8%

price index in 2015 = 210.0%

In this case we want to determine the cost to fill a gas tank in 2015. Let the required cost value be x dolars. Using the formula, price index in 1995/price index in 2015 = reference value/ value in 2015

=> 100.8% /210% = 15/x

=> 2015 cost value, x =( 15 × 210 )/100.8

an urn contains 12 balls, five of which are red. the selection of a red ball is desired and is therefore considered to be a success. if a person draws three balls from the urn, what is the probability of three successes?

Answers

The probability of selecting three red balls or having three successes when drawing balls from the urn is 0.045, which is equivalent to 4.5%.

The probability of three successes can be calculated using the binomial probability distribution formula. Since there are only two outcomes for each ball drawn (success or failure), and the trials are independent, the binomial distribution applies.

The probability of drawing a red ball on the first attempt is 5/12. Since the ball is not replaced, the probability of drawing a red ball on the second attempt is 4/11. Similarly, the probability of drawing a red ball on the third attempt is 3/10.

To obtain the probability of three successes, we need to multiply these probabilities together:

P(three successes) = (5/12) x (4/11) x (3/10)

P(three successes) = 0.04545 or approximately 0.045

Therefore, the probability of drawing three red balls or three successes from the urn is 0.045 or 4.5%. This means that out of every 100 sets of three balls drawn, we can expect to get three red balls in approximately 4-5 sets.

We know that there is at least 1 AB, BJ, and AJ, there must be 3 songs out of 4 songs which Amy, Beth, and Jo listened to.

The fourth song can be of any type : N, A, B, J, AB, BJ, and AJ (there is no ABJ because "no-song" is liked by all three),

So, we must find the number of ways to rearrange AB, BJ, AJ and a song from the set {N, A, B, J, AB, BJ, AJ}.

⇒ Case 1: Fourth song choices = N, A, B, J

All the four of choices for fourth song are different from the first 3 songs.

⇒ Number of ways to rearrange = 4! × 4 choices = 96.

⇒ Case 2: Fourth song choices = AB, BJ, AJ

All 3 of choices for fourth song repeat in the first three songs.

So, Number of ways to rearrange = (4!/2!) × 3 = 36,

So, total number of ways = 96 + 36 = 132.

Therefore, the required number of ways of arrangement is 132 ways, the correct option is (b).

Find the surface area of the sphere

Answers

The calculated value of the surface area of the sphere is  676π

Finding the surface area of the sphere

Given that

Radius, r = 13 inches

The formula for the surface area of a sphere is:

Surface area = 4πr^2

where r is the radius of the sphere

Substituting the given value of radius r = 13 inches, we get:

Surface area = 4π * 13^2

So, we have

Surface area = 676π

Hence, the surface area is 676π

discuss how systematic uncertainty can be estimated for a measured value. how is random uncertainty estimated? what is the difference between error and uncertainty?

Answers

The deviation of a measurement from the true value, while uncertainty quantifies the reliability of the measurement.

Systematic uncertainty can be estimated for a measured value by identifying and evaluating factors that may cause a consistent deviation in the measurements. These factors may include instrument calibration errors, environmental conditions, or personal bias. To estimate systematic uncertainty, follow these steps:
1. Identify potential sources of systematic error.
2. Quantify the magnitude of each error source.
3. Combine these errors, typically by adding them in quadrature (square root of the sum of squares).
Random uncertainty, on the other hand, arises from unpredictable variations in the measurement process. It can be estimated by performing multiple measurements and analyzing the data. The steps to estimate random uncertainty are:
1. Perform multiple measurements of the same quantity.
2. Calculate the mean (average) of the measurements.
3. Calculate the standard deviation, which represents the spread of the data around the mean.
The difference between error and uncertainty lies in their definitions and how they affect measurements. Error is the difference between the measured value and the true value of a quantity. It can be classified as systematic (consistent and predictable) or random (unpredictable and variable). Uncertainty, however, represents the level of confidence with which the measured value is known, considering the limitations of the measuring process. It is often expressed as a range or interval and encompasses both systematic and random uncertainties. In summary, error is the deviation of a measurement from the true value, while uncertainty quantifies the reliability of the measurement.
