logs

f(t)=85 log -16 log (t+1) 0 less than equal to t less than equal to 12
10
t=time in months

round to nearest whole #

I came up with 69 but that was wrong, I think that i am getting messed up on the t+1, can't seem to figure it out, any help greatly appreciated.

Hello, pgotm!

Sorry, your problem makes no sense . . . please resubmit.

\(\displaystyle f(t)\;=\;\underbrace{85\cdot\log}\,-\,16\cdot\log_{10}(t\,+\,1),\;\;0\,\leq\,t\,\leq\,12\)
. . . . . . . . . ??

Round to nearest whole #. \(\displaystyle \;\;\) . . . Round what to the nearest whole number?

Students in an algebra class were given an exam and then tested monthly with an equivalent exam. The average score for the class was given by the human memory model
What is the average score for the first exam? (nearest whole number)
sorry i forgot the problem
f(t)= 85 - 16 log (t+1)
10

Thanks for the help

For first exam, t=1. So we need log(2)=0.301.
Now you do the arithmetic.

thanks pka, sometimes i just need a push.
