Which of the following numbers is irrational? A. 625.499999 B. 625.89 C. 90 D. 900

Step-by-step explanation:

Graphing them is the best way to tell (I put one from Desmos in th attachment scribbled on it a little to match our situation). Otherwise you'll just have to know which one is going to be where on the interval given; but that knowledge comes by graphing them a lot anyways.

Also remember to draw your strips/lines from the axis of revolution to the curves. The longer one will represent the outer radius of the volume and the shorter one the inner radius.

Answer: Choice D

(a-e)/f

=======================================

Explanation:

Points D and B are at locations (e,f) and (a,0) respectively.

Find the slope of line DB to get

m = (y2-y1)/(x2-x1)

m = (0-f)/(a-e)

m = -f/(a-e)

This is the slope of line DB. We want the perpendicular slope to this line. So we'll flip the fraction to get -(a-e)/f and then flip the sign from negative to positive. That leads to the final answer (a-e)/f.

Another example would be an original slope of -2/5 has a perpendicular slope of 5/2. Notice how the two slopes -2/5 and 5/2 multiply to -1. This is true of any pair of perpendicular lines where neither line is vertical.

Answer:

(4,3),y=(7)/(4)x+1

Step-by-step explanation:

To find an equation that is parallel to y = 7 4 x + 1 y=74x+1, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula. ( 4 , 3 ) (4,3) m = 7 4

Using the point-slope form y − y 1 = m ( x − x 1 ) y-y1=m(x-x1), plug in m = 7 4 m=74, x 1 = 4 x1=4, and y 1 = 3 y1=3. y − ( 3 ) = ( 7 4 ) ( x − ( 4 ) )

Solving for y:

Multiply − 1 -1 by 3 3. y − 3 = ( 7 4 ) ( x − ( 4 ) ) y-3=(74)(x-(4)) Simplify ( 7 4 ) ( x − ( 4 ) ) (74)(x-(4)).

y − 3 = 7 x 4 − 7

y = 7 x 4 − 4 y=7x4-4 Reorder terms. y = 7 4 x − 4

Answer:

4.6

Step-by-step explanation:

Answer:

4.6

Step-by-step explanation:

1. We assume, that the number 4 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 4 is 100%, so we can write it down as 4=100%.

4. We know, that x is 115% of the output value, so we can write it down as x=115%.

5. Now we have two simple equations:

1) 4=100%

2) x=115%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

4/x=100%/115%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 115% of 4

4/x=100/115

(4/x)*x=(100/115)*x       - we multiply both sides of the equation by x

4=0.8695652173913*x       - we divide both sides of the equation by (0.8695652173913) to get x

4/0.8695652173913=x

4.6=x

x=4.6

now we have:

115% of 4=4.6

Three reasons why the other method is not better is because to use drawing program would mean you would need some sort of technology and electricity to use it and some places, like third world countries, do not have access to that, so most probably you would have to resort to paper. Also, drawing programs are based off the skills needed to create geometric figures with a straightedge and compass. And lastly, what if we had no more technology anymore? Then how would we use a drawing program? Drawing programs are only reliable when electricity is located.

SO THE ANSWER IS A hope it help :)

I believe that there is a need for students to understand and be able to construct geometric figures using a compass and straightedge.

The compass and straightedge can be used anywhere. The compass and straight edge have been around for lots of years. They are a valuable tool for students in math and in real world applications. The compass and straightedge are portable and handy to use any given time. That is why there is a need for students to understand and be able to construct geometric figures using a compass and straight edge.

The compass and straight edge have been used to accurately create geometric figures for thousands of years. This shows that they are accurate and useful to us. Using technology is less reliable for many reasons. Technology can break, or glitch and shut down, making you lose all your work. You cannot draw on physical objects with an iPad like you could with a pencil or pen. Having a physical copy of things makes things easier to keep track of. Having a blueprint would be better than having a drawing on your phone. You can get another blueprint, but if your phone breaks and that drawing isn't saved, it's gone.

These are only a few reasons why I believe that there is a need for students to understand and be able to construct geometric figures using a compass and straightedge.

Answer:

0

Step-by-step explanation:

Answer: y = 0, 5/12

Step-by-step explanation:

(y)(12y-5) = 0

12y^2 - 5y = 0

After factoring:

y(12y - 5) = 0

Therefore,

y = 0 OR y = 5/12

Unit rate is a ratio between two different units with a denominator of one. When we divide a fraction's numerator by its denominator, the result is a value in decimal form. For example: 8/4 = 2 and 3/6 = 0.5. When we write numbers in decimal form, we can write them as a ratio with one as the denominator.

For example, we can write 2 as 2/1, and 0.5 as 0.5/1. However, since that approach can be a little clumsy, we usually drop the one. That said, it's important to remember the one is there, especially when working with unit rates.

For instance, 8 miles/4 hours = 2 miles/hour. Notice again that, while we did not include the 1, we did include the unit 'hour' Miles per hour is a familiar expression, as are unit rates such as:

interest/amount invested

revolutions/minute

salary/year

Conversationally, the word ''per'' indicates we are using a unit rate.

Answer:

25

Step-by-step explanation:

Given:

n = 33

e = 7

Basically n is the product of p and q

The value of n is given as 33

e is a value chosen such that e , 1<e<ϕ, and that gcd (e,ϕ)

Here the value of e is given as 7

The text/number to be encrypted is also given that is 16

So this means we have to compute the cipher text

We use the following formula from RSA algorithm to compute encrypt number 16. Lets say m = 16

[tex]c=m^{e} mod[/tex] [tex]n[/tex]

Here

e = 7

m = 16

n = 33

So putting in the values:

c = 16⁷ mod 33

  = 268435456 mod 33

  = 25     use modulo operator

c = 25

So the encrypted number is 25

The encrypted number is 25 and this can be determined by using the formula from RSA algorithm.

Given :

Alice has shared that her RSA public key is n = = 33, e = 7.

The formula from the RSA algorithm is used to encrypt the number 16. The formula is given by:

[tex]\rm c=m^e\;mod \;n[/tex]

where e = 7, n = 33 and m = 16.

Now, substitute the known values in the above equation.

[tex]\rm c=16^7\; mod \;33[/tex]

[tex]\rm c = 268435456\; mod \;33[/tex]

Now, by using the modulo function the above expression becomes:

c = 25

So, the encrypted number is 25.

Five out of 10 is 50%

Answer:

50%

Step-by-step explanation:

If there are 5 out of 10 marbles that are red, then there are [tex]10-5 =5[/tex] marbles that aren't red.

This makes the fraction [tex]\frac{5}{10}[/tex]. Converting a fraction to a percent is simple - divide the numerator by the denominator and multiply by 100.

[tex]5 \div 10 = 0.5\\\\0.5 \cdot 100 = 50[/tex]

So 50% of the marbles aren't red.

Only ____6%_______% of customers rated the Delta flight Fair or Poor.

b. The online survey questionnaire enabled respondents to explain any aspect of the flight that Failed to meet expectations. Would this be helpful information to a manager looking for ways to improve the overall customer satisfaction on Delta flights? Explain.

Allowing survey respondents to explain their 5-point scale responses would provide helpful information to managers looking for ways to improve customer satisfaction on Delta flights. The ____6______% respondents indicating that the flight failed to meet expectations would have the opportunity to provide detailed information about their expectations.

Step-by-step explanation:

a) Data and Calculations:

                  Rating Frequency     Percent Frequency

Excellent                18                       ____36%___

Very Good            25                       ____50%___
