I would assume it is F. Try solving it as F. 

Idk how to solve it lol

$\dfrac 1 e = e^{-1}\\ \ln\left(e^{-1}\right) = -1\\ \ln\left(\dfrac 1 e\right) = -1$

Are you studying Number Theory? ALMOST all numbers can be written as a sum of 3 squares, with some exceptions. However, ALL numbers can be written as sum of 4 squares. There is a difficult proof of 3-square theorem by the French mathematician A.-M. Legendre in 1770. There are also special computer programs that will calculate this for you. I wrote one just to see if I could solve your particular problem. I was able to solve it using C++. Here is your answer:

15! =1,307,674,368,000 = 1,022,752² + 511,520² + 64²

A line parallel to the x axis has a slope = 0

So......we have the following equation using the slope = 0   and the point  ( 2 , -3)

y   = 0 ( x  - 2)   -  3

y  =  -3  

[ xy + xz ] / [ z + y ]  =

[x (y + z) ] / [y +  z ]  =

x

Hi, can you please explain why? I'm confused...

1st.group: 3 widgets per worker + 2 whoosits
2nd group: 2 widgets per worker + 2.5 whoosits.
3rd group: 1 widgets per worker + m whoosits.
A decrease in widgets from 3 to 2 per hour, or 1/3, leads to an increase 2.5/2 =25% in whoosits production. 
Therefore, a decrease from 3 to 1, or 2/3, leads to an increase 
of : (2/3) / (1/3) x 25% =50% increase in whoosits. Or:
1.5% x 2 =3 per hour per worker, for a total:
m = 3 x 3 hours x 50 workers = 450 whoosits.

We have this equation

 ( [ E / 5 ] *2 )  + [  ( [ E / 5 ] ) * 2 ]  / 4  =  40       where E is the amount you earn

  Simplify

(2/5)E  + (1/10)E = 40

(4/10)E + (1/10)E = 40

(5/10)E =  40

(1/2)E = 40       multiply by 2

E  = 80

Check

For $80  you will save   (80 / 5) * 2 = 16 * 2 =    $32

And your parents give you   32/4 =  $8   more

x = # $5 unit you earn

2x = amount you save per unit

2x/4  = amount from parents

2x + 2x/4 = 40

10x/4 = 40

10x=160

x = 16   $5 units    = $80     (oops....corrected   16 x5 = 80   not 75 as I originally posted)

I don't know how this works but I can give you a litte info!

15! also equals = 1, 307, 674, 368, 000

m = 450   

If you are looking for the "Greatest Odd Divisor", then you have:

2,278,125 = 3^6 * 5^5

y  =  -3

A room has one door, two windows, and a built-in bookshelf and it needs to be painted. Suppose that one gallon of paint can paint 120 square feet.   The length and width of the door is 9ft by 3.5ft.  The length and width of the windows are 4ft by 3ft.  The length and width of the book shelf is 9ft by 4 ft.  The length, width, and height of the room is 20ft by 25ft by 20ft.  Calculate and output the amount of paint needed to paint the walls of the room.

The area of the sides =  [2length + 2width]*  height  =  [ 2 * 20 + 2 * 25 ] * 20  = [ 40 + 50] * 20 = 90 * 20 =

1800ft^2   (1)

Area of door =  9 *3.5 = 31.5 ft^2  (2)

Area of windows  = 2 * 4 * 3  =  24 ft^2    (3)

Area of bookshelf  =  9 * 4 =  36 ft^2   (4)

So....(assunimg that the bookshelf isn't painted ).....the area to be painted is  

(1)  - (2) - (3) - (4)  =

1800 - 31.5 -  24 - 36   =  1708.5 ft^2

So....the number of cans of paint needed is     1708.5 / 120  = 14.2      [ round to 15 cans ]

Greatest Odd Factor would be 5^5 * 3^3. 3125 * 27 = 84375

This was wrong for me.

 4^4*5^5*6^6?  

37,324,800,000 = 2^14×3^6×5^5 (25 prime factors, 3 distinct)

Awesome.Thanks

The period is    pi / 2

The frequency   =   1 / period   =   1 / [ pi / 2]     =  2 / pi   

So....CORRECT!!!

i think it is 2/pi ?

Huh?

Thank you! Very appreciative of the kind welcome!

Welcome back, rarinstraw.....!!!
