Yes, I know him well.  I sold my soul to the devil several years ago and Mephistopheles was the executive who handled the details.  I sold my soul to Satan to learn math. A few years later, I found myself here, on this forum. I thought it was part of my continuing education but it was really a prelude to helI  and damnation, where I have to teach dumbasses math for all eternity. 

Melody, Cphill, and Alan, all sold their souls to the devil and they are here for the same reason. They are at the top of the list, and their next destination is heII. Don’t worry, though, it’s not any worse than here, –it might be better. 

The whole reason we all love Friday is only because its right before Saturday!

just took the quiz

yes that person is named that, but do you know who he s in real life, the real Mephisto Pheles??

Isn't he the guy who joined up yesterday?

I do very much agree. Those such questions seam an odd manner. :/

(6x^2-14x+12)/(x-1)^4 =0 can someone find me how much x is?

\(\frac{(6x^2-14x+12)}{(x-1)^4} =0\\ \text{First thing to note is that x cannot be 1}\\ 6x^2-14x+12=0\\ 3x^2-7x+6=0\\ \triangle=49-4*3*6=49-72=-23\\ \text{Since the discriminant is negative there are no real solutions}\)

Guest #1 has found the complex (imaginary) roots for you but if you don't know what that means then the answer is

"no real solution"

12 and 8.

[12 + 8] /2 =10 - the mean.

12 - 8 = 4 - The range.

Adam is 3 times as old as Cynthia and Fred is 16 years younger than Adam. One year ago, Adam's age was twice the sum of Cynthia's & Fred's age. Find their present age.

Let Cynthia's age = C

Adam's age =3C

Fred's age =3C - 16

3C - 1 =2[C  - 1 + 3C - 16 - 1], solve for C

C = 7 - Cynthia's age today.

7x3 = 21 - Adam's age today

21 - 16 = 5 - Fred's age today.

21 -1 =2[7-1 + 5 - 1]

20=2[6 + 4]=20 - Their ages 1 year ago.

A "debenture" is essentially a "bond" and is priced as such:

1 - Find the PV of the $12,000,000 par value using the market rate of 12.50%.

2 - Find the PV of the semi-annual coupons at the market rate of 12.50%

3 - Add the two together to get the amount of money raised.

PV of the par value of $100 at maturity =$33.580.

PV of the semi-annual coupons =$65.092

Price of the debenture     =$33.580 + $65.092 =$98.672 per $100.

$98.672/100 x $12,000,000 =$11,840,640 - amount of capital raised.

Solve for x:
(6 x^2 - 14 x + 12)/(x - 1)^4 = 0

Multiply both sides by (x - 1)^4:
6 x^2 - 14 x + 12 = 0

Divide both sides by 6:
x^2 - (7 x)/3 + 2 = 0

Subtract 2 from both sides:
x^2 - (7 x)/3 = -2

Add 49/36 to both sides:
x^2 - (7 x)/3 + 49/36 = -23/36

Write the left hand side as a square:
(x - 7/6)^2 = -23/36

Take the square root of both sides:
x - 7/6 = (i sqrt(23))/6 or x - 7/6 = -(i sqrt(23))/6

Add 7/6 to both sides:
x = 7/6 + (0 + i/6) sqrt(23) or x - 7/6 = -(i sqrt(23))/6

Add 7/6 to both sides:
Answer: |x = 7/6 + (0 + i/6) sqrt(23)      or      x = 7/6 + (0 - i/6) sqrt(23)

You do not need a high powered calculator.  Yo can do it yourself.  :)

let   y=256^(1024^3)

1024^3 = 1073741824

\(y=256^{1073741824}\\ log_{10}y=log_{10}256^{1073741824}\\ log_{10}y=1073741824\;log_{10}256\\ log_{10}y\approx 1073741824\;*\;2.408239965\\ log_{10}y\approx 2585827973\\ 10^{log_{10}y}\approx 10^{2585827973}\\ y\approx 10^{2585827973}\\\)

However, here is the answer using wolfram|alpha  :)

I'm sorry about it. I need to know better about the units. Thanks for the correction, Alan!

Greeting asinus :- )

You need a numerical (or graphical) approach here:

.

grd?   This suggests gradians to me!  Why not deg for degrees?

f(x) = x/4      g(x) = 3x+2   so  f(g(x)) = (3x + 2)/4

(3x + 2)/4 = 1  

3x + 2 = 4

3x = 2

x = 2/3

.

Like so:

.

This is approx. equal to 2.56⁹⁹*10⁹⁹

Generally we use scientific notation for numbers of this magnitute. 

No problem :)

the answer was not a decimal that is why i need help but thank you.

There's nothing more to it than just plugging it into your calculator and making sure that the mode is in degrees.

Literally just put in "  190cos(41)  "

You should get approximately 143.395.

1. Any expression multiplied by 1 remains the same

*1+1
