Pls. Just Part C. [b]Edit: This is the whole question:[/b] [i]"The main section of the suspension bridge in Parc de La Gorge de Coaticook, Quebec, has cables in the shape of a parabola. Suppose that the points on the tops of the towers where the cables are attached are 168 m apart and 24 m vertically above the minimum height of the cables. Use each quadratic function to determine the vertical height of the cables above the minimum at a point that is 35 m horizontally from one of the towers."[/i] [b]Edit 2:[/b] The answer is [b]8.17 m[/b], but I need to show the process.
