Hmm, the thing is that I too forgot the soln. I once solved it very easily but I don't know why I am not being able to do that now. Ok don't worry I will post you the solution after I am able to do it once again.

Anyways, today I was doing some problems on logarithms and my gosh........!!!! SOOOOOOOOO...DIFFICULT problems. I finally started crying..but i still managed to score 10 out of 20.

But I thought it was a picture of yours in the forest; lighting a campfire.

We used to see him on the trail almost every time.

Who is referred as him in the above line?

#229 Re: This is Cool » bobbym, Are you our maths teacher at school? » 2017-04-02 21:21:51

I thought this was a pic of yours taken by some1 else...

Why am I an administrator? Beats me...only MIF can answer that question. But it has been a privilege to serve here and to know the people that are here. A privilege I do not deserve but has been given to me anyway.

Maybe you're a lucky...Anyways this was a post I had posted long back when I just joined here and then I knew nothing about you. I now know all the questions' answers

Who are you bobbym

You are a bumpkin, who loves computer and maths, was poor, did a variety of things, remained a bachelor all life but flirted with the girls.....

how did you become administrator

You became administrator because the reason bob told me in the other thread.

A while back there were lots of spammers and trolls who joined the forum and that's when I was made a moderator to help with removing them.  After bobbym was made an administrator this problem began to go away because he had some clever computer tricks to prevent it.  Nowadays the problem seems to be a lot less so it's unlikely MIF will want to make any new moderators.  I hope I'm not tempting fate sad

He also told me that a while back after making a certain number of posts you will automatically promoted to the next category but has been dropped in the new forum.

where do you live

You live in Florida, USA.

which class do you study

You have passed you school and college and have done a variety of jobs and have now retired and you are 96 now.( Though I hardly believe it.)

Yes, it has: when you factorize it you get :

and when you get the polynomial =0 then you get the 2 roots

Ok, dont worry it happens. Anyways I'm taking the decimal approximation of each of the expressions:

And together they add upto 10 Hrs.

#239 Re: Help Me ! » [ASK] Is This Debit Question Solvable? » 2017-03-31 23:28:07

You mean to say that we can check it by doing the actual practical. Hmm, well I'll see when I get time and will do it. I love doing science experiments at home, and I will try this out.

P.S. You should have Rationalized the denominator in each case; then the fractions would be much more simpler.

#241 Re: Help Me ! » [ASK] Is This Debit Question Solvable? » 2017-03-31 23:10:38

The question says that the total time for draining the whole water is 10 hrs. Just add all the 3 times and then check whether it is coming 10 hrs or not.

#242 Re: Help Me ! » [ASK] Is This Debit Question Solvable? » 2017-03-31 23:04:50

Hi bob,

Yes the pressure will be constantly changing(more correctly decreasing) since the water in the tank constantly decreases and hence the force will be decreasing too.

So you'd have to integrate wrt the height with upper and lower limits for each hole.

Well, if it can be solved, then its good but as you know I don't know calculus I hope you can solve it.

I shall ponder this further.  Maybe I can find a way to do this.

Yes, you can. Try a bit and you will find it (I hope).

Commutative law hold In???

Commutative law holds in multiplication and addition, but not in subtraction and division since

#245 Re: Help Me ! » mcq help for final exams » 2017-03-31 01:49:19

Yeah ,see the denominator part carefully when x=3.

#246 Re: Help Me ! » mcq help for final exams » 2017-03-31 01:44:54

Yes, the slope of a line depends on the function of x.
