If you would, please explain it, but don't make it really confusing, b/c I'm a freshman in high school, and have other homework to do! Thanks!

ok. now in a math question, sometimes you will read this... "where a,b,and c € R" . (the R is really bold) or you will see a sequence and it will say at the end " where x € Z (the Z is really bold " ok, well what does all that mean? the whole "€ R/ Z/ N " is it important? what should i look for in a math problem when i am given that info.

ex. P(z)= Z^3 + aZ^2 + bZ + c, where a, b, and c € R. two of the roots of P(z) = 0 are -2 and ( -3 + 2i ). Find the value of a, of b, and of c.

see, like that prob. so what would i look for? hmm...

oh, and if anyone knows the answer to the ex. math prob. i gave, lol, can you help me with it? i dont know the answer . thanx.

I'm writing a short film screenplay and I need to know how long it would take the average adult to die after consuming a fair amount of the Belladonna leaf. Does anyone know this?

Oh and the movie's called "Nightshade" which I think sounds cool.

To me, speaking of two different brances on the tree of evolution as having evolved from each other is just confusing to most people. As in the lion and the household cat evolving from each other. It is easier to swallow that perhaps they had a common ancestor way way back in time. Evolutionary soundbites never speak of the incomprehensible amount of time that is required for any of these things to happen. No wonder people just don't get it. Maybe it is incomprehensible.
I will accept the wisdom of the internet on this one.

I am in my 3rd year of my Architecture class, and we are beginning to design commercial building designs. We were told to make it "green", meaning that they want me to design the building more environmentally friendly. How are some ways I can incorporate the "green" into my designs? (right now, we are designing a dentist office)

The question is to draw a line-bond structure for propene, CH3CH=CH2, and indicate the hybridization of each carbon and predict the value of each bond angle. I figured out how to draw the lines and how it is arranged, but I don't know why there is a bend in the structure. Why does it bend? Does it have something to do with the hybridization? How do you predict this?

Hi- I am looking to step up my business into a new 23,000 square foot warehouse in Florida. I am trying to estimate my electric bill with the air conditioning. The entire space will have A/C and the ceilings are 25 feet tall and the building will be insulated. I will keep the temp. around 80. I know it will be a lot but does anyone have any idea of how much, or a ball park idea for the summer months, $1,000, $2,000, $5,000 per month?
