If you get snow where you live and you have property that needs to be shoveled, who does the shoveling and why them? also how bad does the snow get where you live? I am a New Yorker and now own a corner property (house) and am not anticipating the snow fall this winter. Looks like it might be time for a snow blower!

water they contain. Surely knowing the visibility in fog would help determine its density and therefore water content, right?

I have a great deal of respect for skeptics of psychic phenomena. If it wasn’t for one rare experience I would be a skeptic too. What I would like to ask is a favor. Would you do a thought experiment? Assuming for a moment that PSI could occur, what do you think could cause it? Do you think it could be a Quantum phenomenon? Does something happen when brain cells split? Could space time irregularities account for it? I really would value your thoughts!

Plz guide me in the following questions, step by step & plz write all important formulas, since my Linear Algebra is not good:

5b-Determine whether the planes are parallel
x-4y-3z-2=0 and 3x-12y-9z-7=0

7b-Determine whether the planes are perpendicular
x-2y+3z=4, -2x+5y+4x=-1

10a-Find parametric equation for the line passing through the given points
(5,-2.4), (7, 2,-4). Answer: x=5+t, y=-2+2t, z=4-4t

11a-Find Parametric equations for the line of intersection of the given points
7x-2y+3z=-2 and -3x+y+2z+5=0 Ans.: x=-12-7t, y=-41-23t, z=t

14a-Determine whether the planes are perpendicular
(-2,1,4).(x-1,y,z+3)=0;(1,-2,1).(x+3,y-5,z)=0

16-Line
x=0, y=t, z=t (-Infinity < t < +Infinity)

a-lies in the plane 6x+4y-4z=0
b-is parallel to and below the plane 5x-3y+3z=1
c-is parallel to and above the plane 6x+2y-2y=3

17-Find equation for the plane through (-2,1,7) that is perpendicular to the line x-4=2t, y+2=t, z=-5t. Ans.: 2x+3y-5z+36=0

Why do we talk about the surface of jupiter as though it had a hard core? Where does Saturn's shadow come from if it's just a gas? I need to understand.

a) prove that an integer n is a multiple of 9 if and only if the sum of its decimal digits is a multiple of 9. [Hint: Consider n − s, where s is the sum of the digits.]

b) Let n =
(765432101234567011223344556677007766554433221101234567)8.
(Thus n is expressed in octal notation.)
Is n a multiple of 7? [Hint: Use (i) generalized.]

please give some hint on how to do "both" of them.. thanks a lot for whoever that can help..
