The functions f and g are integrable and f(x)dx = 9, g(x)dx = 5, and f(x)dx = 4. Evaluate the integral below or state that there is not enough information. 2 N - [ 21( x ) dx 7 . . . Select the correct choice below and, if necessary, fill in the answer box to complete your choice. N O A. - |2f(x)dx = - 10 (Simplify your answer.) N O B. There is not enough information to evaluate - 2f(x)dx. 7Use geometry to nd the displacement of an object moving along a line for the time intervals (i) 0 st: 2 and (ii) 2 sts'l, where the graph of its velocity v = g(t) is given in the gure. 40 30 20 10 (i) The displacement of the object for the time interval 0 5 t s 2 is (Simplify your answer.) (ii) The displacement of the object for the time interval 2 s t s 7 is (Simplify your answer.)
