Geometry problem

[Tahala]

I found this math problem in my math homework... see if you can get the answer!


C is the midpoint of seg. AB, D is the midpoint of seg. AC, E is the midpoint of seg. AD, F is the midpoint of seg. ED , G is the midpoint of seg. EF, and H is the midpoint of seg. DB
If DC = 16 find GH

(Seg. = segment)

And no I didn't put this up to get the answer from you guys... I thought some of you might have fun with it for like 5 mins...

[Xaozaddiction]

42 this is because i didnt have enough lettorz

[SilentRayne]

Good my apprentice..

[Tahala]

Xaoz.. your wrong! :P

[Cthulhu]

Not too hard actually. highlight for answer: 30

[1samurai1]

I take geometry to tahala =D

[Tahala]

Cthulhu... I got 27 not 30

[SilentRayne]

Noooo it's 42 the answer to everything is 42.. and Don't forget your towel!

[1samurai1]

The Answer:Chuck Norris

[Cthulhu]

Cthulhu... I got 27 not 30

Don't defy cthulhu!

[Lovelight]

I also got 30 though. xD

I can show my work too.

[Cthulhu]

Yeah, tah is crazy.

[huggyboo]

Cthulhu you know Math has never been your strong point. And you are using 9th dimensional parallelograms.

[MonsterMiner]

Cthulhu your math is different from us. Don't try to do our math.

[Lovelight]

=3=...
9-D parallelograms. That's new.

I'm like 95% sure that it's 30 though.
Huh...

[Pirate Foxes]

Cthulhu... I got 27 not 30
WRONG!

Other "givens" that I did not list:
C is the midpoint of the segment AB
D is the midpoint of the segment AC
E is the midpoint of the segment AD
F is the midpoint of the segment ED
G is the midpoint of the segment EF
H is the midpoint of the segment DB

It's called a proof. If you are in geometry, you will learn about these later in your schooling year. At first you will hate them...
Now I'm glad I know them.

YES... yes yes yes... I cut some corners on my proof here and I didn't use the proper "->" term... and I didn't put a bar above the line segments...
But I didn't have the ROOM!

HA! 30 is the answer and if you found differently, do your own proof.
Don't argue with a God...
:p



Cthulhu your math is different from us. Don't try to do our math.
Figure THIS one out then:

Y = X^2

(OH this one's EAAAAASY!)
:cool:

[zlyfire]

i take geometry, but its to early for me to answer(7:23 am my time)And pirate, the answer is X=the square root of Y

[Pirate Foxes]

No, that's reversing the problem dude... That doesn't solve anything.

That problem is algebra, not really geometry...
You always have the "Y" on the left side by its self so you map it out to a grid-

Nevermind...

[Cthulhu]

Don't mock my ninth dimensional parallelograms. They got the right answer didn't they?

[cirpons]

Don't mock my ninth dimensional parallelograms. They got the right answer didn't they?

yes all mighty master chultu we will do your biding.:rolleyes:

[Cthulhu]

yes all mighty master chultu we will do your biding.:rolleyes:

Yes, now add those two numbers over there! DO IT!, DO IT NOW!

[1samurai1]

We just did a kids homework and had a 3 page fight over it =D

[MonsterMiner]

Pirate fox all that your problem is Y=X squared
so then I just need to graph the problem out right?

X Y
0 0
1 1
2 4
3 9
4 16

and so on.....
its is parabola and looks like a U

[Cthulhu]

What's the derivative of f(x) = 40x^5 + 23x^3 + x + 8?

Not really supposed to be answered, since I'm sure most of you haven't taken calculus.

[1samurai1]

There was a 8th grader last year who took finished calculus when he finished 8th grade. He took classes after school and was very smart :0
P.S. What a derivative Q_Q

[Cthulhu]

From wikipedia: In calculus, a branch of mathematics, the derivative is a measure of how a function changes as its input changes.

The derivative of position is velocity, the derivative of velocity is acceleration, and the derivative of acceleration is jerk. Taking the derivative of a function gives you a function that shows the change in the first function. Simple. :D

[1samurai1]

Um ok(Can not compute)

[MonsterMiner]

ahhhh, too hard for me....

[Pirate Foxes]

Pirate fox all that your problem is Y=X squared
so then I just need to graph the problem out right?

X Y
0 0
1 1
2 4
3 9
4 16

and so on.....

DING DING DING!

That's exactly it, Monster!
I TOLD you it was easy. :cool:

These are called developmental disorders, and some people on the autism spectrum are actually a lot smarter than the average person, some even have photographic memories or excel in maths. Autism is not a good example of an academic learning disorder, as it is more of a social learning disorder than an academic learning disorder.

Family issues is also a not-so-good example, just because a child may be having problems at home, this doesn't always affect performance at school. Basically it comes down to individual differences, some kids are resilient to things like neglect and abuse, whereas others are affected by it dramatically, and develop disorders.

Bottom line is this: Intelligence is an ambiguous thing, and cannot be defined clearly, let alone rated. In schools children's intelligence is rated on academic performance.
There was a girl at my old highschool who was not as intelligent as the smartest people in the year group but she studied all of the time and got good marks. Compared to me who was more intelligent and considered one of the smarter people of the year group (I am in no way boasting about this, in fact I never saw myself as smart but everyone seemed to think I was. This is for example sake only), but I did not study all of the time and I still got good marks.
This example highlights not only how intelligence has no effect on how well you do if you work hard, but how intelligence makes you lazy as well. I got through school without studying, could I have done better if I had've studied? Probably, but I didn't because I knew that I would do well enough even if I didn't study.

What's the derivative of f(x) = 40x^5 + 23x^3 + x + 8?

Not really supposed to be answered, since I'm sure most of you haven't taken calculus.

Well you know what, I figure ill answer it anyway XD
f(x) = 40x^5 + 23x^3 + x + 8
then
f'(x) = 200x^4 + 69x^2 + 1

Atleast I hope I remembered the right...I never used the stuff after I got tested on it

[zlyfire]

DING DING DING!

That's exactly it, Monster!
I TOLD you it was easy. :cool:

well, it's been a year since i took algebra I and i just simply forgot. Solve this distance word problem: What is the distance between point (3,8,2) and point (9,1,7)?(ps, we haven't learned this in geometry yet, just the Z number, and i thought of this on my own)

[Ivernus]

@ zlyfire I think its 10.48808848
But...could be wrong, been way to long since I've done that stuff.

And while i'm here..ill think ill leave a logic/math problem

Assume you decided to buy a type of mouse that breeds once at the end of each month, birthing 12 babies. These baby mice mature and give birth two months after they're born

Now if you brought the mouse on the day it was born, how many mice shall have been born after 10 months?

[Cthulhu]

Well you know what, I figure ill answer it anyway XD
f(x) = 40x^5 + 23x^3 + x + 8
then
f'(x) = 200x^4 + 69x^2 + 1

Atleast I hope I remembered the right...I never used the stuff after I got tested on it

Very nice, that is indeed the right answer, except that you forgot a dx at the end, although that doesn't really matter that much.

[Mkishere]

Hehe, usually there are written directions telling you it's a function. Usually people don't recognize what kind of problem it is right away.

[Cthulhu]

Wait, isn't that a problem from one of the professor layton games? Anyway, the answer is 0

[Ivernus]

Mmm yeah it was, had just played it earlier that day so some of their questions were fresh in my mind. Silly of me to think no one else would notice :P

Screwball did you post in the wrong thread???
