250 base 10 to 250 base 8

8 250
8 31r2
8 3r 7

Therefore: 7 2 base 8

Here are the 2 initial equations:

x^2 + y^2 = 1 x + z = 2

This is where my initial thoughts are going.

First i need to be able to express (x+z=2) in x. so we have this.

x = 2-z

next well want to sub x into (x^2+y^2=1) now we have.

(2-z)^2 + y^2 = 1
4-4z+z^2+y^2 = 1

y^2 + z^2 - 4z = -3

The above equation does not make sence to me.... Please help if you can. Is there differentation to be done somewhere along the line? I am in a coorespondace course and would really appreciate the help. Im finding it hard to understand the textbook

One night on a dark highway, one of my friends was taking me to another town after work. No other cars around.....up in the distance we could see bright lights. We got up to it, and it was hanging over the highway about the heidth of a tree. The thing was massive in size, as it spread the width of the highway and a little more. It was sort of triangular in shape, but with rounded edges where the corners would be. Along the inside close to the edges, were different colored bright lit lights. I wasn't scared at the time. My friend said on the way back home, the object was gone. We still to this day do not know what it was. I have no explanation, other than that it was an unidentified flying or hovering object. Any answers or similar sightings would be welcome. Thanks!

I already gave a few basic theories proving .999 and 1 are the same number, but he won't listen to any of them. Does anyone have a good solid one?

If 1 = 1, then .999... =/= 1 for if .999... = 1, then 1 =/= 1. If 1=/=1, .999... = 1 however 1=/=1 , so .999...=.999... and not 1.
Damn the paradox!

Edit, my paradox is confusing me, therefore I will right it out in words:

If one is equal to one, then .999 ad infinitum is not equal to one (reason: paradoxical individuality) for if .999 infinite were equal to one, then 1 would not equal one. In this case, .999~ can equal one since one itself may not, however since one is not equivalent to itself, .999~ is equal to itself and not one and vice-versa.

Paradoxical Individuality: A =/= B, for if A=B...B is actually A *or a division of the whole and B is only a misrepresentation of A.





a = 0.999...
10a = 9.999...
10a - a = 9
9a = 9
a = 1
--------------------------------------
a=.999...
a= (in other words ) infinite (~)
10~=~
10~ - ~ = undefined
(the proof should be denounced at this step, shouldn't it?)


I'm not against .999... = 1

I just need to know.
