I'm 19 turning 20 in a few months.I've suffered from Iron deficiency since I was about 13 and have gotten quite a few blood tests done since then.Lately I've noticed that I seem to bruise quite easily even to the extend that my last blood test left me with a bruise from the needle which has never happened to be before and I didn't lift anything heavy all day like the told me too.I've been having sinus infections and colds pretty much all this year and my immune system just seems really week.The last time I cut my thumb it bled for ages and I seem to get bone pain a lot.My last blood test was to look at my hormone levels mainly as well as my iron levels in the blood and came back fine for everything.If I did have leukaemia would it show in the test?If this isn't leukaemia,what could it be?

Given integral sqrt (1-4x^2 )dx, how would you answer the question?

substitute 2x = sin theta
x = 1/2 sin theta
dx = 1/2 cos theta
By formula, I get integral sqrt. (1-sin^2 theta) dx

then which is integral cos theta dx ? Do I sub in dx = 1/2 cos theta ?

If so, 1/2 integral cos^2 theta is what I get...yet I'm pretty certain that I'm not going about this in the right way.

Thank you for answering.

I'm thinking that the gas NH3 is one of the products, but I don't know how to get there. Also, when heated, all of the reactants seem to evaporate, so I'm not sure what the products are.

Possibly NH3 and CO2?

Can somebody please help me with the balancing?

Basically this is a problem I've spent a while working on, and I can't seem to get the right answer.

f(x)=1/(x+3)

^^^Is the function, and I'm supposed to find the difference quotient. We have not really gone over secant/tangent lines yet, so just simplify it in:
[f(x+h)-f(x)]/h

If you could show all your steps, that would be most helpful
Any help would be greatly appreciated.

If they can make a stem cell into a glia cell, they could use them in people who need glia cells. They might be able to do this in the future, but they can't turn stem cells into glia cells yet.

Are my above two statements correct?
I know this isn't perfect, but I don't understand stem cell research very well, and I need the information for a university science project on schizophrenia. I came across an article that said the brains of schizophrenics have fewer glia cells.

-1/2. The answer to the question is (- infinity, -5] u (1,2} u (4, infinity). I don't understand how to do it, a math lab person told me the 2 critical values are 1 and 4, but I don't think thats all there is. thank you so much for your help!

using 1, 2, 3, 4
and....
using parentheses ( ), decimal point '.' , and a minus sign '-'

create the largest number you can.

* you may only use the numbers once, but may use the symbols as many times as you want.

Please help me out, this is really baffling.
thank you so much.
