Just need someone to double check this problem. I just don't feel comfortable with my answer.
An enviromental study of a certain communtiy suggests that t years from now, the average level of carbon monoxide in the air will be Q(t)=0.05t^2+0.01t+3.4 parts per million. (Read as .05t raised to the second power). By approximately how much will the carbon momoxide level change during the next 6 months?
Q'(t) = 0.1t +0.1
change in t=.5
Am I right? If not, where did I go wrong?
I would not do the deraviative.
change in six months = Q(.5) - Q(0)
