I had some problems that I couldn't figure out by myself. I got the formula (100/(1023)

This gives a slighty curved line with Y axis 100 and X axis 1023.

When I want to inverse this formula I get: Sqrt of 0.67 (x/(100/(1023)

But what happens is that the inverse of this formula got an Y of 1023 and X of 100.

My qeustion is there a way that this formula can be written so both plots...

So many teachers, tutors, helpers do this and I just do not understand why.

Almost all (if not all) helpers on this forum and most students who come here for help have studied/memorized/practiced times tables. So why when they have a problem like 9x=90 are they told to divide by 9?? Students should know, and most probably do know, that 9*

Dividing instead of Multiplying--why??]]>

My first step was to prove for n=1 which is true.

Then i use the inductive hypothesis where n=k for k=>1.

After i try to do the inductive step where i end up (k+1+1)!/(k+1+1-2)!*2! = (K+1+2)!/ (K+1+2-3)!*3! which is not equal at all.

Please help and show me where im wrong.]]>

a^2 / (a + b) = d^2 / (c + d), where a & d are unknown, and b & c are constants.

I would like to solve for a in terms of b, c, and d (isolate a in this equality).

This is part of a larger problem I'm working on, but I'm completely stuck right here and drawing a blank on how to handle this.

Any help would be appreciated. Thanks!]]>

I was playing a game of Three card poker at the casino the other night (fyi it is a game where the player is dealt 3 cards and the dealer is dealt 3 Cards from a 52 deck shoe.) one hand was dealt where we ended up with the same hand.

My hand was Q , 7 , 3

And the dealer hand was also Q , 7, 3

so I didn't win or lose it was 'stand off'

it got me think what the odds are of this happening and I thought I had it...

my first calculation was to assume the dealer had 3 separate...

I’m wondering if it’s possible to calculate coordinates to a point in a 2D plane given the following:

I have three signal sensors lets call them a, b and c.

b is placed on the y axis 10 centimeter from the origin (x,y = 0,10), c on the x axis 10 centimeter from origin (x,y = 10,0) and a on the origin (x,y = 0,0).

The point I want to calculate gives out a signal and I only know the ratio of the signal strength between any of the three sensors ab, ac or bc from the point to the...

This may seem like a really simple question to some people in here but I've never had to deal with such problems and therefore don't even know how to start. I'd be thankful for any hints or maybe somebody could tell me what I have to read on to be able to solve this.]]>
