Suppose that a student has 195 vocabulary words to learn. If a student learns 19 words in 30 minutes, the function L(t) = 195 (1 - e -0.00351 ) models the number of words L that the student will learn after t minutes. (a) How many words will the student learn after 48 minutes? The student will learn approximately |words. (Round to the nearest integer as needed.) (b) How many words will the student learn after 69 minutes? The student will learn approximately words (Round to the nearest integer as needed.)
