Title: Homework Help/Tutoring
Post by: y00tz on August 24, 2007, 01:56:33 AM
I just thought I'd let you know that if you need help with your homework, regardless of grade or subject, this forum is cluttered with intelligent people that could help you, so don't be afraid to post here and ask for help.

I'm sure between the intelligence of the forum users, our Googling power, and the random references cluttering our bookcases, we could probably help you out.

Yeah well I hate that class because it's all online and I am too lazy to actually do it. I mean seriously I am paying a $500 a credit hour and the professor gets paid for giving me a password to do a test. >:(

I wouldn't' mind if she shopped at the most expensive store IN TOWN, but there isn't even a Bloomingdales in Missouri, meaning my Shabbat is often spent driving to Illinois.

 Ok, I need helps.

Greek philosopher is trapped in jail. There are 2 doors in the jail and 2 guards guarding the doors. 1 door leads to freedom, other to hell. The guard guarding the door to heaven never lies. The guard guarding the door to hell always lies. The philosophist can go out from either of those doors and he can ask 1 question from those guards. He asks "Are you guarding the door to heaven?". The guards answers either "yes" or "no". Now, how can the philospher be sure which guard is guarding which door and get out safely?
Title: Re: Homework Help/Tutoring
Post by: bitmate on September 26, 2007, 10:58:29 AM
Is he allowed to ask each guard, or can he only ask one of the guards?

Wait, so that's the only question he can ask?

xy – a = ax + y How do you solve that for x? Would it be x = (ax + y) + a) / y?
Title: Re: Homework Help/Tutoring
Post by: ViciouZ on October 08, 2007, 03:18:00 PM
xy -a = ax + y

x = (a + ax + y) / y is what I get. But I'm probably wrong.
Title: Re: Homework Help/Tutoring
Post by: SmackWaters on October 08, 2007, 03:28:27 PM
Well, it depends. Do you divide the y or add the a first? I can't remember.

Simplify:   

1-csc x
csc x



sin²u x cot²u + sin²u



sin(x-(pie/6))




tan7u + tan5u
1-tan7u x tan5x


Any type of showing steps shown would be wonderful.

Post by: DaRkNeSS on December 21, 2007, 01:02:21 AM
Given:


Cos x = (2/3) and 3pie/2<x<2pie, find cos(x/2)



Title: Re: Homework Help/Tutoring
Post by: sk89q on December 21, 2007, 02:28:52 AM
Only going to do the first one since I'm reading a book.

Just change csc(x) to 1/sin(x), and then you've got a fraction over a fraction. The rest should be algebra -- no more identities needed.
Title: Re: Homework Help/Tutoring
Post by: DaRkNeSS on December 21, 2007, 02:44:13 AM
Thanks.
Title: Re: Homework Help/Tutoring
Post by: sk89q on December 21, 2007, 03:06:21 AM
Okay, second one:

sin^2(u)(cot^2(u)+1)    -- distributive property

Then, change cot^2(u) to cos^2(u)/sin^2(u), use some algebra to un/re-distribute it, sin^2(u) should cancel on the first term (the fraction), and then use the identity cos^2(u)+sin^2(u) = 1

Third one, I guess you could use the sum/difference identities, but I don't know if that really counts as simplifying. (sin(u-v)=sin(u)cos(v)-cos(u)sin(v))

Fourth looks like a royal bastard and I don't see a way to do it easily off my head.

And fifth, it's been too long since I've done trig and it's too late for me to try too hard. :P

Hello old thread.

The function f(x) = ax^3 - 7x^2 - bx - 20 is divisible by x^2 - 3x - 10.  Find the values of a and b.

I've spent more than the past hour working on this question with a friend, and we just can't get anything out of it.  The only place I could find any other question like this was in my textbook, but it had no help and description of how to do it, just the answer to it only.

Title: Re: Homework Help/Tutoring
Post by: Gamabunta on February 02, 2010, 05:21:13 PM
Whoa, think I may be a little to late but still.
@Cam
x^2 - 3x - 10 = (x - 5)(x + 2), let's call it w(x). w(x) zeroes for x = 5 and x = -2, and so does f(x). Put 5 and -2 on place of x in f(x) and it equals zero, like:
Code: [Select]
{ a*5^3 - 7*5^2 - b*5 - 20 = 0
{ a*(-2)^3 - 7*(-2)^2 - b*(-2) - 20 = 0
This leads to an answer that a=3 and b=36, unless I made a mistake.
Hope that solves the problem, if it still exists.

Permutation and Combinations

1. How many 13 card hands are there having exactly nine cards from any suit? Answer: 235 237 860

2. How many ways are there of picking 2 cards, one after the other, from a deck of 52 cards if the
A) First card is replaced?      Answer: 2704
B) First card is not replaced?   Answer: 2652

3. In how many ways can a 5 question test be answered if each question is to be answered true or false? Answer:32

I need help on how to do it, please. I'm betting i could get these questions if i took my time, but i don't feel like doing it right now.
Title: Re: Homework Help/Tutoring
Post by: Cameron on February 05, 2010, 01:13:56 AM
Haha, probability.

1) Don't understand the question.  Is it how many 13 card hands can be made up of 9 cards of the same suit?

2a) nCr(52,1) x nCr(52,1) = 2704.  Basically thats 52 ways of getting the first card AND (in probability X is always and, + is always or) 52 ways of getting the next card.
b) nCr(52,1) x nCr(51,1) = 2652, quicker still is nPr(52,2), use that when its not being replaced :P.

3) 2^5 = 32.  Which is essentially nCr(5,0) + nCr(5,1) + nCr(5,2) + nCr(5,3) + nCr(5,4) + nCr(5,5).  Meaning there is 1 way of giving no answers, 5 ways of giving only one answer, 10 ways of giving 2 answers, etc.  Add em together because its not giving 1 answer AND 2 answers, its 1 answer OR 2 answers.
