These are about calculus. I would like them all solved correctly.

Question 9 Not yet answered Marked out of 1.00 V Remove flag Find the signed area between the graph of y = x2 8 and the xaxis, over the interval [2, 4]. Question 6 . . . . . . N Use calculus methods to find the pomt on the IIney = 2x + 15 that Is closest to the origin. at yet answered (x, y) = ([:],[:]) Marked out of 1.00 V Remove flag Recall that the distance between points (x, y) and (xo,yo) is given by the formula: s = y/(x x0)2 + (y yo)2 . Hint: Since distance is always positive, you may find it easier to minimise the function 32
