After a foreign substance is introduced into the blood, the rate at which antibodies are made is modeled by
f(t) = 17 t
7 t2 + 7
where f(t) is in thousands of antibodies per minute, and t is measured in minutes with 0 ? t ? 120. Assuming that there are no antibodies present at time t = 0, find the total number of antibodies in the blood at the end of 120 minutes. Round your answer to two decimal places.
Number of Antibodies (in thousands)
