Alright, this might be simple, but I don't get it.

How does .... (8⅓)² become (2)² ????

I was thinking that (8⅓) = 8/3...... Because isn't (8⅓) = (8 x ⅓)??

So how does (8⅓) end up being (2)² ???

if: x=.999....
then
10x(9.999...)-x(.999...) equals 9x
so
x=1
so then 1=.999... what's the deal?

-12+1/4=?

Element / Melting point (C) / Boiling point (C)
Radon / -71 /-61.8
Neon /-248.7 / -246
Bromine /-7.2 /58.8

a. for each of these elements, find the differnce between its boiling point and melting points.

b. which of the elements is liquid in the widest range of temperatures?

c. which of the elements is lquid at 0 C



Explain whether it is always true that the differnce between two numbers is smaller than either of the numbers? Give an example to justify your answer.

Please help, they are part of my math homework and I do not understand what it is talking about and I was hoping that one of you guys would know. Please I need some answers ASAP.

I am adapting a blind adaptive channel equalizer using CMA. Both the channel and the equalizer are modeled as LTI FIR filters. But how can the equalizer be (approximate) the inverse of the channel if it also FIR?

Over the weekend I went on a saltwater fishing trip,and had a thought or two,but couldn't figure it all out.
Here's the thought: If I could get the fishing line with the heavy sinker to stop just before it hit bottom,I wouldn't have to wait for all the silt that washed up from it hitting bottom to clear up.How long would it take for a 10oz sinker to free-fall through 250feet of water(assuming no drag).
The physics formula for calculating air drop would be ...
D = ((1/2 AT^)V1T))
where D is distance
A is acceleration
T is time
V is Velocity
I remember A being 10meters/sec.,but that is for air test as it is acceleration to the ground.
250ft is just under 77 meters
