16. Use (a) the Trapezoidal Rule and (b) Simpson’s Rule to approximate the integral to four decimal
places. Compare your results with the exact value.
17. Eight milligrams of a dye are injected into a vein leading the an individual’s heart. The
concentration of dye in the aorta (in milligrams per liter) measured at 2-sec intervals is shown in
the accompanying table. Use Simpson’s Rule with and the formula
to estimate the person’s cardiac output, where D is the quantity of dye injected in milligrams,
is the concentration of the dye in the aorta, and R is measured in liters per minute. Round to one
decimal place.

18. Find a bound on the error in approximating the integral using (a) the Trapezoidal Rule and
(b) Simpson’s Rule with subintervals.
19. A body moves along a coordinate line in such a way that its velocity at any time t, where ,
is given by
.
Find its position function if it is initially located at the origin.
20. Determine whether the improper integral converges or diverges, and if it converges, find its value.
