You should do what I do, don't sleep! I can't remember the last time I didn't wake up at 2am and get on this web. :))

the answer is 21 you stupid for asking the question

Sorry Cphill-is    the RIGHT numbers were 9 and 18.....   So-o-o-o-o close!     No prize and NO PARTICIPATION AWARD either!

Pretty good.....

8  and  19

OK.......what do I win  ????

ohh, okay :)

dude its old just drop it

Probably due to "Post-Holiday Blues,"   Hayley......

Coldplay is correct......much livelier last night.....

Ill take the money! :)

This is a geometric sequence: sqrt(12), sqrt(3), sqrt(3/4), sqrt(3/16), sqrt(3/64), sqrt(3/256).....and so on. Keep multiplying the denominator by 4, so:256 X 4=3/1024, 3/4096.........etc.

I'm NOT sure as to you want: The sum of the 1st. 20 terms is:6.9281966............etc.

The 20th term is 3/68,719,476,736.

P.S. This is in Albanian language. 

A= [-3  5  -6

       9  -5  3]

B=[ -2  6  7

       2  -1  6] 

-3A  = [ 9    -15   18            6B =  [ -12   36    42

            -27   15   -9]                        12    -6    36 ]

-3A + 6B   =  [ 9 + -12     -15 + 36    18 + 42         =       [ -3      21      60

                      -27 + 12      15 + -6     -9 + 36]                   -15      9      27 ] 

I did, how bout you?

9189 x 1% = 9189 x .01 = 91.89 added to her account      9189 + 91.89 = 9280.89 at the end of the year

1. replace all letters with the alphabet table. You will get a number sequence.

2. Write down the numbers in a matrix. Since your got a 2 dimensional matrix choose your encoding matrix to be a square matrix.

3. multiply the matrices

1- The monthly payment @ 6%=$612.09

2- The monthly payment @ 5%=$555.36

Therefore the difference between the two interest rates is:

$612.09 - $555.36=$56.73

Write down an equation with the missing element to be the numerator like:

1 pound / $3.55 = x pounds / $12

then solve the equation

(1 pound / $3.55 ) * $12 = x pounds = 3.38 pounds

This always works for similar situations.

The sky.

Not much, I'm bored:)

It was busier last night.

1- The monthly payment @ 8.75%=$1,603.18

2- The monthly payment @ 5.25%=$1,168.53

Therefore the difference between the two interest rates is:

$1,603.18 - $1,168.53=$434.65

This is cool!

OK I get 8.93 feet in one second. What do you get XV

oh? Might want to watch what you say..

The ! sign is used to indicate the factorial function.  N! means N*(N-1)*(N-2)*...*3*2*1

So, for example, 5! = 5*4*3*2*1 = 120

.

Triangles have 3 sides!  An equilateral triangle has all sides equal, so their length is d/3 cm

.

Initial momentum of the system = 0.

Crate acceleration along ramp = g*3/5   (component of g along ramp)

Velocity of crate (along ramp) at B given by  v^2 = 2*(g*3/5)*L   (L = length of ramp).

Horizontal component of crate velocity v_crate = -v*4/5   (with horizontal velocity positive to the right).

Momentum of system when crate reaches B:    m_crate*v_crate + m_ramp*v_ramp = 0

See if you can take it from here.
