i would like to know how to find the max. in a function

like the maximum of the function:

A(w)=w(40-2w/2.57)

how do u go about finding the max that "A(w)" can be.

thank you

I want to fit 55mw laser to my celestron skycout instead of a 5mw.
Now orion offers a bracket that u could stick a 5mw laser that orion offers to be connected to the celestron skyscout. The bracket might not hold a 55mw laser thats why im asking for the circumference

I saw the movie Boondock Saints not too long ago (I'd recommend it for any who haven't seen it). Toward the end of the movie, the two protagonists (who are extremely lucky crime-fighting vigilantes) use a spray-bottle of ammonia to cover up their spilled blood. Somehow, this made it impossible for forensics to acquire a DNA sample from those blood-spots, when they appeared in a later scene.

If I had to guess, I'd say that ammonia [is supposed to, in the movie] neutralize DNA, because ammonia is a base and DNA is an acid ("DNA" stands for "deoxyribonucleic acid")

So my question is: can ammonia neutralize DNA or otherwise make it impossible to take a sample? Or is it really just diluting it to a point where taking a sample is nearly impossible?

In asking this I also remember that urine has a high ammonia content, yet, to my knowledge, I don't think this prevents anyone from acquiring DNA samples from urine.

Happy 2007 to everyone...

I have 3 chemistry that are all very similar but I do not understand the meaning behind it or how to solve it even with the solution manual's answer. I was wondering if someone could explain it to me. Thank You.

Q: All the molecular equations below have the same net ionic equation in aqueous solution except:

1. HI + KOH --> H2O + KI
2. HNO3 + NaOH --> H2O + NaNO3
3. HF + NaOH --> H2O + NaF

A: 3

Q: All the following acid-base reactions have the same net ionic equation except:

1. HF + RbOH
2. HClO4 + KOH
3. HNO3 + NaOH

A: 1

Q: All the reaction below have the same net ionic equation except:

1. NaOH + HBr
2. RbOH + HF
3. BA(OH)2 + HI

A: 2

Need a macro to get the sum of some data, the amount of which changes. Example: I have 10 sales data this month in cells A2:A11 and next time I will have 20 data in A10:A30 (some other data in A1:A8. A9 is blank). How to write a macro that gives me the total sales every month, knowing how many cells be used for the calculation? The total amount should be in the cell 2 rows below the last data cell. (A13 for this month and A27 for next month in the example above).
I will appreciate it if you could show me the codes. I was told to use either a Range or a For Next Loop. I think that is right but do not know how to do it (I am new with VBA). I tried with the range but could not finish it.

(Start from the cell 2 rows below the last data)

Active cell. Offset(-2,0). Select
Range (active cell, Active cell.End(xlup)).Select
How to write the code to calculate the sum of the selected range?

I would also like to learn to write the For Next codes for this problem.

Thanks a lot!!

Imagine a drop of water as in the link is a black hole.
http://focus.aps.org/story/v4/st9

As the black hole seperates from the universe the drop instantly blows up or 'splashes' into the 4th dimension in the same way a drop hits a surface on earth. But instead of the outside of the drop hitting the surface the hit originates in the very center of the drop which blows it up.

Look at that splash. The mirrored image helps but in the big bang imagine that splash isn't just the top and bottom but rather all the way around it. The splash originates in the very center rather than the outside.

it makes sense in terms of physics and geometry.

Prove me wrong!

That if we prove beyond a shadow of a doubt that black holes exist, that we also prove general relativity? This is rationalized by the fact that according to general relativity, black holes are predicted, meaning if we find black holes, general relativity is correct.
