Suppose that a student has 500 vocabulary words to learn. If the student learns 15 words after 5 minutes, the function L1t2 = 500(1 - e-0.0061t ) approximates the number of words L that the student will learn after t minutes. (a) How many words will the student learn after 30 minutes? (b) How many words will the student learn after 60 minutes?
