Hey everyone, hope someone can help me with this problem. I just got back from Spring Break and for some reason have forgotten how to do this... Thanks in advance for any help you can give me!

Suppose that in a memory experiment the rate of memorizing is given by:

M'(t)=-0.009t^2+0.2t

where M'(t) is the memory rate in words per minute. How many words are memorized in the first 10 minutes (from t=0 to t=10) ?
