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.
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
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...
