[tex]( \sin^{2} ( \frac{\pi}{ 4 } - \alpha ) ) = \frac{1}{2} (1 - \sin(2 \alpha ) )[/tex]
Prove

Answers

Step-by-step explanation:

[tex] \sin^2 (\frac{\pi}{4} - \alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

Use the identity

[tex] \sin^2 \theta = \dfrac{1 - \cos 2\theta}{2} [/tex]

on the left side.

[tex] \dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

[tex] \dfrac{1 - \cos (\frac{\pi}{2} - 2\alpha)}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

Now use the identity

[tex] \sin \theta = \cos(\frac{\pi}{2} - \theta) [/tex]

on the left side.

[tex] \dfrac{1 - \sin 2\alpha}{2} = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

[tex] \frac{1}{2}(1 - \sin 2\alpha) = \frac{1}{2}(1 - \sin 2\alpha) [/tex]

in order to do this, we would use order of operations. First, Parentheses, which is division with fractions, so we would do KCF,keep it, change it, flip it. keep the first fraction, change the operation to multiplication, then flip the next fraction, making it -7/9 x 3/1. the answer would be -2.33. multiply that by -2, and you would get -4.66, which is your answer.

How could the statement "12 less than x" be written?

Answer:

The statment would be written as "12 - x".

A 12 cm by 20 cm painting hangs in a museum. The museum curator wants to hang other paintings in the gallery that are proportional in size. The dimensions of several paintings are shown. Which paintings' dimensions are proportional to the original painting? Select all that apply. A. 1.5 cm by 2.5 cm B. 27 cm by 45 cm C. 9 cm by 15 cm D. 30 cm by 50 cm E. 6 cm by 14 cm

Answers

Answer:

A. 1.5 cm by 2.5 cm

B. 27 cm by 45 cm

C. 9 cm by 15 cm

D. 30 cm by 50 cm

Step-by-step explanation:

The dimensions of the original painting = 12 cm by 20 cm painting

Hence, the proportion is:

12/20 = 0.6

Hence, we compare the options given in the question.

A. 1.5 cm by 2.5 cm

= 1.5/2.5 = 0.6 , option A is correct

B. 27 cm by 45 cm

27cm/45 cm = 0.6 Option B is correct

C. 9 cm by 15 cm

9cm/15cm = 0.6 , Option C is correct

D. 30 cm by 50 cm

30 cm /50 cm = 0.6 Option D is correct

E. 6 cm by 14 cm

6cm/14 cm = 0.4285714286

Option E is not correct

Therefore, Options A to D are the correct options

Can I plz get the congruence and reason plz

Answers

Congruence is when there are 2 objects that have the same shape and size, or they "mirror" each other.

Question 6:

Congruence:

Yes, these two objects are congruent.

Reason:

They are congruent, because they have the same size and shape, or that they "mirror" each other.

Question 7:

Congruence:

Yes there is congruence, here. These two objects are similar shapes, but not completely congruent.

Reason:

These two objects have the same size, but not the exact same shape. If you look at point B you can see that the two angles are different, which means that they are similar shapes, but not completely congruent.

Hope this helps! :)

Step-by-step explanation:

Step 1: Define

-5x - 1 ≤ -9

Step 2: Solve for x

Add 1 to both sides: -5x ≤ -8Divide -5 on both sides: x ≥ 8/5

Here we see that any value x greater than or equal to 1.6 would work as a solution.

Therefore, our answer is A. 1, as it doesn't work as a solution.

Answers

Answer:

1. Unbiased sample.

2. Self-selected sample.

3. Stratified sample.

4. Systematic sample.

5. Convenience sample.

6. Biased sample.

Step-by-step explanation:

1. Unbiased sample: sample where every member of the population has an equal chance of being selected.

For example, a researcher randomly selecting a shopping mall and questioning the customers coming there.

2. Self-selected sample: sample where members volunteer to take part.

For example, a researcher uploading a questionnaire online and then requesting for brainly members to take part.

3. Stratified sample: members are selected from the different subgroups within a population.

For example, when a geographical region is stratified into subgroups by climate, habitat, soil type or elevation. A population grouped by males or females.

4. Systematic sample: sample members are selected through the use of a rule.

For example, a researcher selecting the 10th house on a particular street.

5. Convenience sample: sample where representatives are easily accessible.

For example, a researcher using a social media poll such as Twitter polls.

6. Biased sample: sample not representative of the entire population.

For example, a researcher selecting only females when trying to determine the best cook in a class.

Answer:

1. biased sample

members are selected from the different subgroups within a population

2. convenience sample

sample members are selected through the use of a rule

3. unbiased sample

sample where representatives are easily accessible

4. self-selected sample

Noya needs to determine the number of books that will fit into a box. If the box has a length of 18 inches and each book is StartFraction 2 Over 9 EndFraction of an inch thick, which expression can be used to determine the number of books that will fit into the box? 18 2/9 18 times 2/9 2/9 divided by 18 9/2 divided by 18

Answers

Answer:

A. 18÷2/9

Step-by-step explanation:

A. 18÷2/9

B. 18×2/9

C. 2/9÷18

D. 9/2÷18

Let

Total length of box = 18 inches

Thickness of each book = 2/9 inches

Number of books that will fit into the box = x

Number of books that will fit into the box = Total length of box ÷ Thickness of each book

x = 18 ÷ 2/9

= 18 × 9/2

= 162/2

= 81 books

The correct answer is A. 18÷2/9

Part 1: Explain what the following variables represent and how changing each one affects the monthly payment amount: P, i, and t.
Part 2: Explain how changing each variable (P, i, and t) affects the total cost of principal and interest over the life of the loan.

Answers

Answer:

Part 1 and 2: P represents principle, or the original cost of the mortgage. i represents the annualinterest rate (r/n), and t represents time. When you change the time it affects monthlypayments because theres either more or less time to pay off the mortgage. Having a longertime to pay off means you'll have lower monthly payments. When the interest rateincreases, the monthly payment increases. This is because the higher the interest rate, themore interest you're paying. Changing the principle means you either have more or lessmoney to pay off.P2: Increasing i will increase the total cost since more interest will be charged. Increasingtime means there's more periods for interest to gather so the total cost will increase.Shortening the time will decrease the total cost because there will be less time for interestto accumulate.

Would you be able to see through walls or use your eyes to zoom in on tiny, miniscule objects? Computer chips may not give you supersight, but they may help some blind people finally see.2Replacing body parts with mechanical devices is called bionics. Scientists have been developing bionic body parts for a long time, but in the last 20 years, they have started using computer chips to make bionic devices better and more effective.3To place a computer chip in an eye, a doctor makes a tiny pocket in the retina, the back of the eye. The retina is like a movie screen, and the lens at the front of your eye focuses light onto it. The computer chip, about the size of a pinhead and thinner than a human hair, is placed inside the tiny pocket. The chip senses light and helps a person see.4Six people were in the first group to allow doctors to put chips in their eyes. The patients say the computer chips have helped them see better. Before the operation, one patient could only see objects that were a few feet away. After the operation was completed, he said he could see a flock of geese flying through the sky. Another patient who saw only darkness before the operation can now see light and shadows. "Someone came along and developed this little thing to put in your eye, and suddenly I can see more light," he said, celebrating his improved sight. "None of us had expectations that we'd be able to see someone's face or read a book. Eventually, it'll work."Which detail from the passage describes how the computer chip is placed in the eye?AThe lens in the eye focuses light onto the computer chip.BA tiny pocket is made in the retina for the computer chip.CThe computer chip is placed next to the eye because it is too big to actually fit inside.DThe patient has to remain awake because the eyes must be open during surgery.Read the passage.Which detail from the passage describes how the computer chip is placed in the eye?AThe lens in the eye focuses light onto the computer chip.BA tiny pocket is made in the retina for the computer chip.CThe computer chip is placed next to the eye because it is too big to actually fit inside.DThe patient has to remain awake because the eyes must be open during surgery.
