Those are called disjoint sets.

im doing a world history 2 project based on the inventions made in the early times of the US, and I was chosen to do the bike.....


The problem is that there's a question that asks how does the bike solve problems?


well other than being a faster way of transportation, does anyone else have any ideas?

[RDS1]

Doesn't it have, like, the most efficient force input/output ratio of any form of transportation, or something?

I don't know; I'm working from the memory of something I heard one time about three and a half years ago (I think; I wasn't paying close attention).

You should probably try asking in the Homework Help topic, or whatever it's called.

[superflous]

Yeah, don't ask the lounge, nobody ever comes here.

Also, convenience, can go anywhere pretty much, eco-friendly, etc.

[RDS1]

Exercise?

[Ze Colonel]

Eco-friendly.
Cheap (in comparisons to other options).
Still in use today, when there are faster methods.
It exercises your body, while getting you somewhere faster than walking.
Perfect for going places a car cannot. A ride in the park, a bike up a mountain trail.
Can be used in sports and tricks for entertainment or as a profession.

And I'm sure others~

Moved. Too lazy to keep up the "hudur not mod" since it gets somewhat obvious. We still have one more anon anyways.

Easier to manage than a horse.
- no horseshit
- no feeding
- no tieing up a live animal to a post
- no saddle maintenance
- reduced cost of care for horse (no more food, additional housing, etc); aka economically its more viable
- user friendly

It's the fastest on short distances through a city.

I know this is /really/ easy I just for some reason can't think today and I can't get the right answer.

Simplify the expression. Write the answer using only positive exponents.

(((a^3)(b^6)(a^-1)(b^5))/(a^5)(b^3)))^-2



Edit: I'll see if this way of looking at it is less confusing:

( a^3 * b^6 * a^-1 * b^5
-------------------------- -2
a^5 * b^3)
</feeling dumb>

[superflous]

Er, so...

a3b6a-1b5
a5b3

All to the -2?

I'm not writing carrots >_>

Well, first off, I'd bring a^-1 down, because negative exponents= pretty much flip that part.
So, a^-1= 1/a

So, that would then be
a3b6b5
a5b3a

When you multiply the same variable, you add the exponents.
Which is why a*a= a^2 because a^1*a^1== a^1+1

So, simplify

a3b11
a6b3

Now, it is the reverse when you divide, meaning you subtract exponents, so...

a^3-6 b^11-3
Which is
b^8
a^3

And then, when you have something like this (a^2)^2 you multiply the exponents.

SO

b^-16
a^-6

Flip!

a^6
b^16

Therefore...

a^6/b^16

QED!!!!!!!!!!!!!!!

If anyone is good at chemistry, then I present you a challenge:

1. A gold sphere with a mass of 1,200. kg and a temperature of 100.0°C was plunged into
an insulated vat of water. The mass of the water was 2.000 kg and its initial temperature
was 25.00°C.
a. What will be the final temperature of the system when stabilized?
b. Determine the radius of the sphere (in inches).

I'd appreciate an explanation on how to reach the answer as well.

[Thunder_man6]

For the life of me I can't figure this out, I must be having an off night as this should be really easy.


Factor the polynomial by factoring out the opposite of the GCF.
-15(x^10)(y^3)+27(x^9)(y^2)-18(x^8)(y^2)

Find the point P on the graph of
y=1/(2 x)
such that the line through P and (1, 1/2) has slope -4/5.
IMPORTANT: Provide exact expressions, not decimal approximations.

Find all values of k such that the equation
x^2+kx+17=0
has one solution. If there is only one answer, enter it in both answer boxes. If there are two solutions, enter the SMALLER solution in the first answer box and the LARGER solution in the second answer box.
