5. Consider the function f (3:) = 2 :52 over the interval [1, 3]. Use summation notation to express the right Riemann sum with 50 subintervals. 6. Suppose the right Riemann sum R100 has been found to be given by the expression 100 k 1 R = ' 5 . 100 ESIH( + 20) 20 Determine the function f (3:), the interval [(1, b], and the number of rectangles n used in the calculation of this Riemann sum. 7. Express the limit . V 2 * \"lingo 21 sm (27ml) Am as an integral over the interval [0, 1]. 8. Evaluate the integral of the piecewise dened function graphed below on the interval [0,12]. Use geometry formulas for the areas of triangles and circles} and remember to subtract the areas below the Liaaxis
