A college language class was chosen for a learning experiment. Using a list of 50 words, the experiment measured the rate of vocabulary memorization at different times during a continuous 6-hour study session. The average rate of learning for the entire class was inversely proportional to the time spent studying, and was given approximately by V't)= for 15156. Find the area between the graph of V' and the t-axis over the interval (3,5), and interpret the results. The area between...

In a particular business college, it was found that an average student enrolled in an advanced typing class -0.25t progressed at a rate of N'(t)=(t+6) e words per minute per week t weeks after enrolling in a 16-week course. A particular student who can type 30 words per minute enrolls in the course. Use the given information to answer the following three questions. How many words per minute N(t) would the student be expected to type t weeks into the...
