In about 5 billion years from now, our sun will become a red giant and will engulf all the inner planets. Most likely, life on Earth will die long before this happens. But if humans could somehow manage to evacuate into space, do you believe we could live on Titan?

Well, you're actually a Doctor, Pangolin, I just wanted to know if any of the surgeons where you work would be willing to talk to me about the career? I'm a 15-year-old Sophomore in High School, and I want to go into Surgery, and I just thought talking to a Surgeon would be especially enlightening, or actually talking to YOU, like over AIM or MSN or something?

I want to purchase a pond vacuum which requires about 40 PSI. I don't need an EXACT measurement, just something to go by. The garden hose is a standard type, half an inch diameter, about 50 feet long on a slight incline and I've measured the water flow to be about 10 to 12 gallons per minute.

take the ration of 2/1^3 or to be read 2/1 cubed.
(1= 220hz/ 2=440hz) to the third power or cubed.
This is in relation to the squaring and cubing of harmonic ratios. in this case an octave or a ratio of 2/1 is being squared and cubed.

The diagonals of rectangle ABCD intersect at point E. If measure of angle BDC is 30 degrees and
AE =8 sqrt 3 units, find the area of the rectangle.

The area of a rhombus is 7.5 sq. in. Find the length of the two diagonals if one of them is one more than twice the other.

Thank so much!

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide. in sulfur dioxide, there are 32.06 g. of sulfur and 32.00 g. of oxygen. in sulfur trioxide, 32.06 g. of sulfur are combined with 48.00 g. of oxygen.

a. what is the ratio of the weights of oxygen that combine with 32.06 g. of sulfur?

b.How do these data illustrate the law of multiple proportions?

In QI, he said what animals can give birth to either a 'Lili' or a 'Titi', and claims it's a liger.

Ligers (lion and tiger mix) can't actually breed, much like a mule (horse and donkey mix). This is because they are different species and, infact, one way to distinguish between species is the ability to produce fertile offspring.

Just a bit of info!

Night all :)

I finished most of my hw except these problems. Please show work.
1) Find the limit:
lim x->infinity (x^4 +x^3)/(12x^3+128)

2) Find the limit:
lim x -> negative infinity e^(3t)inversesine(1/t)

3) If lim x->c (f(x)+g(x)) = 3 and lim x->c (f(x)-g(x)) = -1, find lim x->c f(x)g(x).

3) Find the limit and state if the function is continuous at the point being approached.

lim x->0+ sin((pi/2)e^(square root x)

4) Find a simple basic function as a left end behavior model and a simple basic function as a right end behavior model.

y = (2x^4 - x^3 + 2^x - 1) / (2 - x)

thank you very much!
