A figure is located at (0, 0), (−3, −4), and (−3, 0) on a coordinate plane. What kind of 3-D shape would be created if the figure was rotated around the x-axis? Provide an explanation and proof of your answer to receive full credit. Include the dimensions of the 3-D shape in your explanation.

Find a Saccheri quadrilateral in the half plane that has its base Gn the line y = 25 -(x-4)2. State the vertices of the quadrilateral and the equations that its sides lie on.

The parabola y = Px² + Qx + R passes through the coordinate (1,1) and has roots at x = a and x = b. Determine the values of P, Q and R.
