The "Moon-sized Mars" business caused coronaries in this section, and that's only a few weeks each year. It's still 5 years plus 2 days until 2012 and they're already coming thick and fast (especially thick). It will be an effort of supreme willpower for some of us, but why don't we give up and let the weird answerers give weird answers? It's not like the whole world comes here for knowledge.

I need to make sure I have the right answers for the values of these trig functions. Help?

I'm supposed to find the values of the trig functions for the negative angles, and rationalize the denominators.

Can you help please?

Thanks!


1. cos ( - 150 degrees)

2. cot ( - 330 degrees)

3. sin ( - 135 degrees)

Make sure to remember that they're negative. Thanks so much!

You are explaining to friends why astronauts feel weightless orbiting in the space shuttle, and they respond that they thought gravity was just a lot weaker up there. Convince them and yourself that it isn't so by calculating how much weaker gravity is at h = 490 km above the Earth's surface.

What would be the end result if that happened? Would our earth go back into time? What do you think?

So for my Grade 11 Biology Culminating Activity, I had to grow 15 bean plants over a period of 1 month. I had to use one variable per 5 plants. I chose to use the amount of water and I used 5 mL for 5 plants, 10 mL for 5 plants, and 15mL for the other 5 plants. My project failed miserably as NONE of my plants grew. Could somebody please do me a GIANT favor and tell me what you think the daily growth per variable would be? (i.e. How much would the 5mL plants grow per day, 10mL, and 15mL as well.)

I would appreciate this ASTRONOMICALLY! Thank-you in advance.

How come some countries are hotter than others? Is it that the sun is actually closer to that part of the earth or what exactly?

I have to divide x + 2 into f(x) = x^3 + 9x^2 + 7x + 3 and then write my answer in the form given by the Division Algorithm; x^3 + 9x^2 + 7x + 3 = q(x)(x+2) + r(x) for some polynomials q(x) and r(x).
How do I do this?
Thanks very much!

I had to do write these triangle inequalities and now i have to add them up, but I'm not sure how.

PY+PY>XY
PY+PZ>ZY
PX+PZ>XZ

What does that add up to be?

Thank you for your time.
