Sup Shane :cool:

hola shane! como estas?

Ciao! Mi scuso per questo, ma ho avuto modo di scendere e fare del lavoro a casa ora così sarò in un secondo momento! arrivederci!

lolwut?

era italiano, proprio come sto parlando ora!

shane - okay. have fun with that :D what kind of homework? :wacko:

:curtain:

eh, la matematica e la scienza :blank:

shane - aw i'm sorry :hug: i'm sure its nothing too difficult tho :nice:

ALYSSA :DDDDDDDDDDDDDDDDDDDDDDDD

Hey kids I could do your math homework... or at least I hope so. :p

LAURA!!!! :cheesy:

 

Oh, can you do mine? I suck at cross-multiplying...:sick:

ooh fractions? :wacko:

I could try.

I don't have to do maths any more :smug:

:lol:

I hope someone is typing some problems because I was serious about attempting to solve them. :P

If you solve this you get a hug :nice:

 

5x^-2y^10 over 2x^-1(-3x^-3y^-1)^-2

 

:awesome:

A 'snooker' table (measuring 8 metres by 4m) with 4 'pockets' (measuring 0.5m and placed at diagonal slants in all 4 corners) contains 10 balls (each with a diameter of 0.25m) placed at the following coords:

2m,1m...(white ball)

...and red balls...

1m,5m... 2m,5m... 3m,5m

1m,6m... 2m,6m... 3m,6m

1m,7m... 2m,7m... 3m,7m

 

The white ball is then shot at a particular angle from 0 to 360 degrees (0 being north, and going clockwise).

Just to make it clear, a ball is 'potted' if at least half of the ball is in area of the 'pocket'

 

Assuming the balls travel indefinitely (i.e. no loss of energy via friction, air resistance or collisions), answer the following:

 

a: What exact angle/s should you choose to ensure that all the balls are potted the quickest?

b: What is the minimum amount of contacts the balls can make with each other before they are all knocked in?

c: Same as b, except that each ball - just before it is knocked in - must not have hit the white ball on its previous contact (must be a red instead of course).

d: What proportion of angles will leave the white ball the last on the table to be potted?

 

@William:

 

What do you mean by 'over'?

 

:uhoh:

 

edit: okay Dave, I'll read your post now

 

edit2: maybe I can solve that if you give me a few months xD

:sneaky:

Do you know how to solve it? If yes, how?

 

edit: I'm off to bed now. Will check this thread the next time I log in.

I'll give you an some easier ones :lol:

 

1. A case weighs 4KG correct to the nearest Kilogram.

Calculate the upper bound of the total weight of 12 of these cases.

 

2. Rearrange the formula to make d the subject.

 

cd= 5(d-e)

:dance:

 

But how will you be sitting next to all of us without body doubles? :P
