Solve the equation :
\( \cos(x) - \sin(x) = \sqrt{2 } \: cos(3x)\)
Answers
Answer:
General solution is
\(x = n \pi + \frac{\pi }{8}\)
Step-by-step explanation:
Step(i):-
Given cos x - sin x = √2 cos (3 x)
Dividing '√2' on both sides , we get
\(\frac{1}{\sqrt{2} } cos (x) - \frac{1}{\sqrt{2} } sin (x) = \frac{\sqrt{2} cos (3 x)}{\sqrt{2} }\)
we will use trigonometry formulas
a) Cos ( A + B) = Cos A Cos B - sin A sin B
b) \(cos \frac{\pi }{4} = \frac{1}{\sqrt{2} }\)
Step(ii):-
\(\frac{1}{\sqrt{2} } cos (x) - \frac{1}{\sqrt{2} } sin (x) = \frac{\sqrt{2} cos (3 x)}{\sqrt{2} }\)
\(cos (\frac{\pi }{4} ) cos x - sin(\frac{\pi }{4} ) sin x = cos 3x\)
\(cos (\frac{\pi }{4}+x ) = cos 3 x\)
Step(iii):-
General solution of cos x = cos ∝ is x = 2 nπ+∝
we have \(cos (\frac{\pi }{4}+x ) = cos 3 x\)
The general solution of \(cos (\frac{\pi }{4}+x ) = cos 3 x\) is
⇒ \(3 x = 2 n \pi + (\frac{\pi }{4}+x )\)
⇒ \(3 x- x = 2 n \pi + \frac{\pi }{4}\)
\(2x = 2 n \pi + \frac{\pi }{4}\)
final answer:-
General solution is
\(x = n \pi + \frac{\pi }{8}\)

A swimmer can complete 1 lap across a pool in 1/3 minute. If she maintains that pace, how many laps will she have completed in 10 minutes?
Will it be less than or greater than 10?
Answers
Answer: If the swimmer can complete 1 lap across a pool in 1/3 minute, she can complete 3 laps in 1 minute.
In 10 minutes, she would complete:
3 laps/minute x 10 minutes = 30 laps
Therefore, the swimmer will have completed 30 laps in 10 minutes if she maintains that pace.
Since 30 laps is greater than 10, it means that the swimmer will complete more than 10 laps in 10 minutes.
Step-by-step explanation:
Greater than 10, because she swims 3 laps in each minute.

Beth works at the mall for $12.75 per hour. She works for 4 1/2 hours per day on 2 days each week. How much does she make in 2 weeks? (Before taxes)
Answers
Answer:
so she works 4 days and 4 1/2 hours per day so 18 hours
18x12.75=229.5 she made 229.5 before tax
Step-by-step explanation:
she goes to work 2 days a week so in 2 weeks she goes to work 4 days, she works 4 1/2 hours so 4 days of work equal 18 hours and 18 multiplied by 12.75 is 229.5
Answer:If I am not mistaken it should be $229.5
Step-by-step explanation:I multiplied 12.75*18, I got 18 from the hours added up for 4 days in total.Then the answer came out to be $229.5. SORRY IF I'M WRONG.

Brainlist for positive attitude and correct answer :D
Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

An accountant charges a fee of $120 to complete a company's taxes. The accountant also charges an additional $40 per hour to complete the taxes. Which of the following equations can be used to describe this problem?
y = 40 + 120x
y = 40 − 120x
y = 120 + 40x
y = 120 − 40x
Answers
Answer:
y = 120+ 40x
Step-by-step explanation:
The $40 is the rate of change meaning that that would be the number that is next to the variable and the 120 is just staying there meaning it does not have a variable.
if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The fixed fee of $120 is represented by the constant term in the equation, and the additional fee of $40 per hour is represented by the coefficient of x.
As the number of hours worked by the accountant increases, the total fee also increases at a rate of $40 per hour, hence the linear equation.
The equation that can be used to describe the accountant's fee is:
y = 120 + 40x
In this equation, y represents the total fee, and x represents the number of hours worked by the accountant.
Hence, if accountant also charges an additional $40 per hour to complete the taxes then the equation y = 40 + 120x can be used to describe.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Show all steps for findin the diagonal of the box above using the formula instead of the Pythagorean Theorem twice.
Answers
Answer:
BD = √(18² +4²) = √340; AD = √(12² +(√340)²) = 22AD = √(12² +18² +4²) = 22Step-by-step explanation:
You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.
Pythagorean theorem twiceThe length of BD can be found from ...
BD² = BC² +CD²
BD² = 18² +4² = 340
BD = √340 ≈ 18.439
and
AD² = AB² +BD²
AD² = 12² + 340 = 484
AD = √484 = 22
The lengths of the face and space diagonals are ...
BD = √340 ≈ 18.439AD = 22FormulaNo formula is given as part of the problem statement. We can simplify the above calculations to get ...
AD² = AB² +BD²
AD² = AB² +BC² +CD²
AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula
AD = √(12² +18² +4²) = √(144 +324 +16) = √484
AD = 22
