1. 1/x-1 + 2/x-2 + 1/x-3 (three fractions in the expression)
2. 1/x+y - 1/x-y + 2x/x^2-y^2 (again, three fractions)
3. 3/x^2+x-2 - 5/x^2-x-6 (three fractions)

Thanks!

Ok. I know that to be a mineral it must be inorganic (not coming from a living thing).

BUT heres where I'm confused - don't diamonds come from coal which is not a mineral because it came from the remains of plants long ago. SO - how can diamonds be a mineral if they come from something organic??

Can someone explain please?

The directions say to: use the fours tep process to find the slope of the tangent line to the graph of the given function at any point.

then it gives problems like these:

f(x)=13

f(x)=2x+7

f(x)=3x^2 ----- (3x squared)

f(x)=-x^2+3x

How do I work one of these? I looked at my notes but I cant seem to figure it out.

I am trying to do a Project for my science teacher about Acids in Foods. One of the questions is How are acids used to make the food you selected? I have been looking for a web site that will tell me how acids get in the food I selected, which is Apples, but I can't find one! If anyone knows of a web site that deals with this, it would help a lot, because whenever I search for something on the internet, it comes up all heartburn remidies and apple recipies! I need help!

Why does It happen always when I feel that a girl is attracted or recognize me, or when I'm attracted to her, & I feel that everything is going fine, I feel that strange feeling that I can't control what I'm saying and my body language, and everything then gets ruined and screwed up. Can someone help?!!

Suppose, 2 yr from the date of Manufacturing is expiry date. Now, if one consumes it after 2yrs + 8 months, then will it be harmful ?

--Well, I know it depends upon the type of medicine, but, in general, I think most medicines should not harm even if they're consumed after expiry date.

What is your opinion ?

You have several single socks in your drawer. They are all the same style but 9 of them are green and 8 of them are purple. Assuming you cannot see the colors, what is the smallest number of socks you have to remove from the drawer so you are guaranteed to have a pair that is the same color?

I came across this question from the 2000 AP exam, and it seemed easy and so I answered it by now I don't know if it's right!!

H2S(g) 2 H2(g) + S2(g)
(a reverse reaction!)

When heated, hydrogen sulfide gas decomposes according to the equation above. A 3.40 g sample of H2S(g) is introduced into an
evacuated rigid 1.25 L container. The sealed container is heated to 483 K, and 3.72 ×10-2 mol of S2(g) is present at equilibrium.

(a) Calculate the equilibrium concentration, in mol L-1, of the following gases in the container at 483 K.
(i) H2(g)
(ii) H2S(g)

(b) Calculate the partial pressure of S2(g) in the container at equilibrium at 483 K.


Thank you!
