Find the area enclosed by the x-axis and the curve y=1tet v=t-t2. (Show all work separately and submit on HuskyCT immediately after submitting your answers) A= [A]

2. The curve determined by the equation y2 = x²(x + 3) intersects itself, forming a loop. Find the area enclosed by this loop.

Find two z values so that 58% of the middle area is bounded by them. Use a TI-83 Plus/TI-84 Plus calculator and round the answer to four decimal places, separated by a comma if needed. z =
