Hi, again I am stuck on something simple and its one of them annoying prrove questions that you cant check your answer in the back of the book.

It says:

Given that k is a real constant such that 0
a) always real
b) always negative

well firstly I dont get how if the roots are real (and positive) how they can possibly be negative, but for part a at least I have done the following

Its a question about the discriminan b^2 -4ac and since b=2 a=k and c = 1-k I have done the following showing that the answer has to be greater than 0

so 2^2 - 4k(1-K) >0
so 4 - 4k + 4k^2 >0
divide the whole lot by 2
so 2 - 2k +2k^2 >0
so 2k^2 -2k > -2
so 2k(k-1) > -2
so k(k-1) > -1

but im stuck there and have no idea where to go next or how to show they are always negative

and 13 times 28 equals 364 which is pretty close to 365.. why do we have 12 months and not 13?

Find the largest integer which is both an n-digit number and an nth power.

If you find the answer, let me know how you got it as well as what it is! 10 points for the correct answer with the clearest explanation.

Thank you.

Hi! I'm doing some chemistry, and I've reached a part about moles, which, in my opinion, is simple but they try to make it more difficult than it has to be (who knows, maybe I'm over-simplifying it and it'll bite me in the butt later). That's what I'm trying to find out. Please tell me if this is correct (I've read through like 10 pages of explaining and this is basically what I've summized).

For the question, "The molecular formula of hydrogen peroxide is H[sbscrpt2]O[sbscrpt2]. What is the gram molecular mass?"

So basically, take the atomic mass of 1 atom of each element. That equals 1 mol. Multiply it by however many moles there are (a.k.a. how many atoms of that element there are), and that is the gram molecular mass.

Is that right? By my figuring that would work out to:

(# of atoms, written as mol) X (atomic mass) = answer in g

2 mol H X 1.0g / 1 mol H = 2.0g H
2 mol O X 16.0g / 1 mol O = 32.0g O
Total gmm = 34.0g

Thank you, I really appreciate this!
