I think the problem is in your password.

You need to include a special character like '!', '@', '&' in your password.

I was stuck in this step too so when I add @ into my favourite password it works and I have become a member since then.

Thanks all for answering :)

Stuck at this question on an online exercise.

Not all the 3 lengths of sides are given.

Therefore 12 may be the hypotenuse.

I will assume that 12 is the length of the hypotenuse.

Another side = sqrt(12^2 - 5^2) = \(\sqrt{119}\)

Area = 5 x sqrt(119)/2 = 5/2 sqrt(119)

\(\log_x\dfrac{1}{3}\geq2\\ x^2\leq\dfrac{1}{3}\\ x\leq \dfrac{\sqrt3}{3} \;or\;x\leq-\dfrac{\sqrt3}{3}\\ \therefore x\leq \dfrac{\sqrt3}{3}\\(\text{because the range }x\leq-\dfrac{\sqrt3}{3}\text{ coincides with the range }x\leq \dfrac{\sqrt3}{3})\)

5/6 ÷ 7/12

= 5/6 x 12/7

= 10/7 :)

\(\displaystyle\sum^{\infty}_{n=1}\dfrac{5^{n+1}}{3^{n-1}}=\displaystyle\sum^{\infty}_{n=1}\left(\dfrac{5^n}{3^n}\right)\left(\dfrac{5^1}{3^{-1}}\right)=\displaystyle\sum^{\infty}_{n=1}5\cdot3\left(\dfrac{5}{3}\right)^n=\displaystyle\sum^{\infty}_{n=1}15\left(\dfrac{5}{3}\right)^n\)

:) Hope this helps 

Ummmm

And any isotopes of iron.

*showing off my chemistry skills although I just started chemistry lessons this year*

26 protons means its atomic number is 26. That means it is iron :).

*Pikachu isn't using iron tail.*

Hope this helps :):)

I will give my own definition with my understandings.......

Life, is that when you can't be omniscience, when you can't be omnicompetent, when you can't be perfect. Life is when you are physically and mentally existing, when you try to have your physical body and your mind linked, when you try to get a new life.

A simpler version:(I think that's a bit different )

Life:

1. You CANNOT be perfect in life.

2. You try your best in your life.

3. You are forced to cherish your life.

It takes me some time to write these sentences. I checked 'omnicompetent' up because I have this word in mind but I don't remember what is its meaning. I hope this will help you.
