Solve for t: y0ekt = y0 / 2 y0 > 0, k >0
I have no idea how to approach this problem. I don't even know what category this falls under so I'm having trouble googling info this type of problem.[/b]

in my experience y sub 0 usually indicates the value of y at time = 0 and is usually some constant.
I think your problem is related to decay processes and the t value here represents the half life of your sample.
Mod note: This looks like homework. Let me urge all members to restrict their responses to HINTS ONLY. Thank you.
Its not homework its a question from a sample exam paper. Its supposed to be y0^ekt. I couldn't [SUP] tags to work on this forum.
Same thing. [sup] tags have been disabled because we have a LaTex facility.
Your question, then is, if
, then solve for .
This is an elementary halflife problem whose solution is simple algebra. Where are you stuck?
I did a bit of algebra and got
but I'm assuming they gave me the info
y0 > 0, k > 0
so I can solve for k and fully solve for t.
EDIT: Can't get the latex to work.
the tags will work after a few posts of yours. It's afaik a precaution to prevent spammers from posting offensive pictures
