i read 4 questions per minute,i use 2 papers per question, how many papers are used in 1 hour.
4 question per minute, and 2 papers per question, so how many paper do you use in one minute (for 4 questions) ?
\[\frac{ 4 ? }{ \min }\frac{ 2p }{ ? }=\frac{ 8p }{ \min }\]
4 per 1 2*4per 1min 8*60 per 60min
4 questions/min * total number of min will give you total number od questions you can solve in that time(in this case it is 60min) . multiply this number 2 (number of papers you use per question) will finally give you number of papers you use in that time.
i think 480 papers in 1 hour
is the function of the papers P,and questions q, \[P(q)=q^2-\frac{ 2 }{ q }\] sorry this is correct
and i read 4 questions per minute
Find the rate at wich paper is used
previous ? settled
does that make sense
\[\frac{ dP }{ dq }\frac{ dq }{ t }=\frac{ dP }{ dt }\]
\[(2p+2q^{-2})(\frac{ dq }{ dt })=4\]
\[\frac{ dq }{ dt }=\frac{ q^2 }{ 2q^3+2 }\] sorry only q
yes now its a new question with a function
so @theloser if it was cont the problem will be solved
\[p'(t)=8q+8q^{-2}\]
thanks guys i just made up the question s its not standard
hey ok.. you can solve it now, dp/dt = (dp/dq)*(dq/dt)
