I think I understand the process a bit better now, thanks InteGrand. Before I was just using a formula that I knew applied to the question but I didn't exactly know what was going on.

Thank you for your help! I cursed myself when I realized that I should have divided by three before taking the log of everything. once again- thank you so much.

Anyone got any ideas?

hi, would you please be able to help me with this maths problem- I'm desperate http://community.boredofstudies.org/586/general-university-discussion/335675/first-year-maths-question.html

thanks, I'll try sending Drognoski a message

yeah- I'm still stuck on this question. I also tried this method y= A x 10^kx find A when x= 0 ( y= 3 at x=0) A=3 y= 3x 10^kx i tried to substitute in the point (1, 30) to find K but i kept getting 3.0959 which doesn't make sense. anyone's thoughts on this would be greatly appreciated.

here's how I tried to approach the question since the log scale is one the y axis logy= mx+ b y= 10^ (mx + b) y= 10^(mx) x10^b I think this should be the formula, but then again i have no clue what I'm doing. I tried to say that b= 3 but i just don't know where i am going with this...

I'm not sure if this is the right place to post this thread, but could someone please help me with this question, I don't even know where to start.
