Answer:

Step-by-step explanation:

cos^8a+sin^8a=1-sin^22a+1/8sin^4a​

Answers

cos⁸A+sin⁸A = (Cos⁴A)² + (Sin⁴A)²

=> (Cos⁴A + Sin⁴A)² - 2Cos⁴ASin⁴A

=> [(Cos²A)²+(Sin²A)²]² - 2(CosASinA)⁴

=> [(Cos²A+Sin²A)² - 2Cos²ASin²A]² - 2(CosASinA)⁴

=> [1 - 2Cos²ASin²A]² - 2(CosASinA)⁴

=> [1 - 2(CosASinA)²]² - 2(CosASinA)⁴

//Remember: Sin2A = 2SinA CosA => SinACosA = 1/2Sin2A

=> [1 - 2(1/2Sin2A)²]²- 2(1/2Sin2A)⁴

=> [1 - 1/2Sin²2A]² - 1/8Sin⁴2A

=> 1 + 1/4Sin⁴2A - Sin²2A - 1/8Sin⁴2A

=> 1 - Sin²2A + 1/8Sin⁴2A

Which of the following best describes the relationship shown in the equation below?


A.
It cannot be determined if this is or is not a functional relationship.
B.
This is a functional relationship.
C.
This is not a functional relationship.

Answers

Answer:

C. this is not a functional relationship.

Step-by-step explanation:

In other words, for each x-value, there is only one corresponding y-value.

For the equation x2 + y2 = 10, find the y-value for a given x-value.

Let x = 1.

Since (-3) · (-3) = 9 and 3 · 3 = 9, there are two y-values for x = 1.

Dr. Reyes is examining whether exercise is linked to mood. She recruits a sample of college students and asks them to answer whether they exercised at least three times last week (yes or no) and to rate their mood in the last week (1: Not happy at all to 5: Very happy). Her results show that students who exercised in the last week also reported happier moods. Can Dr. Reyes make a causal inference from her study

Answers

The answer to whether Dr. Reyes can make a causal inference from the study is;

No, she can't make a casual inference from the study because she met only one of the three criteria's for causality.

To answer this question, we need to know the conditions for causality in statistics research because causality gives the relationships such that a change in one variable would have to result in a change in another variable.

Now, the three conditions are;

1) Covariation; This condition means that the causal variable must have to vary with with the variable it is assumed to cause in a systematic manner.

2) Temporal precedence; Thus condition simply means that cause must precede effect. In summary it denotes that the variable that has the causal effect must come before the effect that it is meant to cause.

3) Control for extraneous variables; This condition means that results of an experiment or research must not be due to factors outside of the experiment/research

     Now, in our question, he fulfilled the covariation condition because the

result of the research is tied to the responses from the sample students.

However, she did not fulfill the temporal precedence because the cause of

their moods did not precede the effects in his research.

Also, she did not fulfill the condition of control of extraneous variables

because other factors outside of the research itself may have affected their

moods.

A group of 20 friends are going to travel to a school reunion together, 7 of them can drive. They have a 7 seat car (1 driver and 6 passengers), a 5 seat car (1 driver and 4 passengers) and the remaining 8 will take a bus. How many ways can the friends travel (ignoring passenger seat positions within each vehicle)? Give an exact answer, do not round. Do not include commas or dots in your answer.

Answers

Using the combination formula, it is found that there are 99768240 ways in which they can travel.

The passenger seat positions are not important, which means that the order is not important, which is why the combination formula is used.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem:

In the first car, 7 of the 20 friends are going to sit.In the second, 5 of the remaining 13 are going to sit.In the bus, the remaining 8.

The, the number of ways is given by:

[tex]N = C_{20,7}C_{13,5}C_{8,8}[/tex]

[tex]N = \frac{20!}{7!13!} \times \frac{13!}{5!8!} \times \frac{8!}{0!8!} = 99768240[/tex]

write the log equation as an exponential equation. you do not need to solve for x.

Answers

Answer:

[tex]5^{1/6} =2x[/tex]

Step-by-step explanation:

Log and exponential forms are inverses. Additionally, the information from one can be used to write in it another form. In a log equation, there are three parts. The formula is [tex]log_{b}(x)=y[/tex]. The formula for exponential equations is [tex]b^y=x[/tex]. This means to find this equation in exponential form write 5 as the base, 1/6 as the power, and 2x as the other side of the equation. This looks like, [tex]5^{1/6} =2x[/tex].

Help me please!!! It’s due at 11:59

Answers

Answer:

18

Step-by-step explanation:

Let the required number be x.

Step 1

write the expression for the difference of the number and 4.

=> x - 4

Step 2

the question equates 5 times the difference with some other terms, so find the equation for 5 times the difference.

=> 5( x - 4)

Step 3

The equation in Step 2 is said to be equal to "two less than four times the number".

Find the expression for four times the number

=> 4x

Step 4

Find the expression for two less than 4x.

=> 4x - 2

Step 5

Equate the terms that it says are equal:

=> 5(x - 4) = 4x - 2

distributing 5 within the parenthesis:

=> 5x - 20 = 4x - 2

taking like terms on one side:

=> 5x - 4x = 20 - 2

(the sign carried by the terms get inverted while changing their sides)

=> x = 18

and x was the required number, so the answer Is 18.

Step-by-step explanation:

She needs 160 for a free ticket and get 85 for signing up.

Every time she goes, she get 12.5 points

160=85+12.5v

The answer would be C

Reason:

We eliminate B and D as they do not have a total of 160 points.

We are now left with A and C

A shows that she would need to earn 85 points three times which is incorrect as she receives 85 points 1 time after signing up. Therefore we eliminate A.

We are now left with C

C shows that the total amount of points she would need to earn a free ticket are 160 points.

It also shows that she would receive 85 points 1 time after signing up.

It also shows that the remaining points she would get are from strictly visiting the movie theater.
