Pukka36:
Jetibrain!!!.....What is the answer to the second one@Medwhite0?

its simply because sound needs a material
medium for it propagation... so your ear will serve as a medium for propagation.

Good afternoon madam.

RobinHez:

Looooool...like I said, there are various ways of solving a mathematical equation. Nd thank God I mentioned the geometric progression method in my 2nd post.

Cheers!

OK bro.

RobinHez:

Chillax bro...I've not gone against any rules in maths.
Yeah I know there are other ways of solving it like the Geometric progression way,

Check this one out also
1/9=0.111
9 × 0.111... =0.999...
and 9 × 1⁄9 =1,
so 0.999... = 1:

U can see that we used fractions to also show it.
There are many ways of solving maths bro.
So how did u prove it?

0.9999=1

0.9999 is an infinite series.
and 0.9+0.09+0.009+0.0009= 0.9999

first term=0.9
and common r= second term/first term.
=0.09/0.9
=0.01

sum of infinite series= a/1-r

=0.9/1-0.01
=0.9/0.9
=1
thus 0.9999=1

RobinHez:

Well if u insist...
Let's say 0.999...=an unknown value (x)
(...Means it continues to infinity)
Then 0.999...=x
We've gotta manipulate here (cuz its maths)
Multiply through by 10
10x=9.999...
10x=9+0.999...(Which=9.999...)
Recall 0.999...=x
Therefore, 10x=9+x
10x-x=9
9x=9
X=9/9
X=1
That means 0.999...=1

No bro.

RobinHez:

Round up to a whole number

no...
I said prove that 0.9999 = 1.

anybody??

medwhite0:
prove that 0.9999=1

RobinHez:

Its D

seconded.

prove that 0.9999=1

RobinHez:

That's not fair na...there are a lot of guests relying on these threads 4 info

yeah ....true.
