What is the definite integral that is associated with the following Riemann Sum? n- N . In n n i=0 A) Jordx C) S2 xdx E) None of the above. B) Sixdx D) S3 xdx\f8. Suppose that for each i such that 1 S i S N one has )4 f(t)dt = 2' What is fol\" f(t)dt? A) 25 C) 45 E) None of the above. B) 35 D) 55 14. 15. Consider the function y = 932 9. on the interval [-b, b]. What value does b have to be in order for the area between 3; and the xaxis and [b, b), to equal -36? A) 0 C) -9 E) None of the above. B) 9 D) 3 Consider two functions y1 = f (:17) and y2 = g(cc), and that yl 7E yg except Where they intersect. If these two functions intersect at 14 places, how many different integrals do you need to nd the total area enclosed by the two curves? A) 13 C) 15 E) None of the above. B) 14 D) 16 21.
