r l ' Compute / 3 dx, expressing the result in terms of r. 0 (25 x2) (Express numbers in exact form. Use symbolic notation and fractions where needed.) r 1 d : f0 (25 _ x2)3/2 x Calculate the sided limit to determine what happens to the denite integral as r approaches 5 from the left. (Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if the limit does not exist.)
