Use geometry (not Riemann sums) to evaluate the definite integral. Sketch the graph of the integrand, show the region in question, and interpret your result. 10 100-x dx 0 G Q G 10 The value of the definite integral S 100-x dx as determined by the area under the graph of the integrand is 0 Q Use only the fact that 6x(2-x)dx = 8 and the properties of integrals to evaluate the integrals in parts a through d, if possible. 2 a. Choose the correct answer below and, if necessary, fill in the answer box to complete your choice. O A. 0 0 S6x(2-x 2 (Simplify your answer. Type an exact answer, using radicals as needed.) OB. The integral cannot be calculated using the given information. -x)dx:
