I mean the hole starting just anywhere on the surface and ending exactly on the opposite side of the Earth planet. See what I mean? I know it's impossible but at least in theory how will he fall? What if the hole wouldn't cross the center of the earth but only will be made somewhere on the edge?

A travel agent offers two package vacation plans. The first plan costs $360 and includes 3 days at a hotel and a rental car for 2 days. The second plan costs $500 and includes 4 days at a hotel and a rental car for 3 days. The daily charge for the room is the same under each plan, as is the daily charge for the car. Find the cost per day for the room and for the car. (Please show your system of equations and answer the question in a complete sentence.)

- so the answer is $80 dollars for the hotel, but i do not understand how they got that answer...

Okay, my friend and I were trying to figure this out. She says that "-x squared" is negative x and taking the square of it (looks like this (-x) squared.) However, I do not agree...I think it is x squared and then you take the negative of it. (Looks like this: -(x)squared) I think it is based on order of operations. (you know PEMDAS) She thinks I am very wrong. We are working with parabolas so please help me out. Thanks a bunch!

For some time now I have alwasys been pondering on things that may never be answered. What is life? What do we "see"? What happens when we die? We "see" through our eyes yet not "see" through other peoples eyes. Its all to weird for me to explain it all. What if the world is gone, what will happen if there is no such thing as orginisms left in the "universe". And one more thing, What is the "universe"?
