, a curve that is roughly the shap… Show more The Saint Louis Gateway Arch has the shape of an inverted catenary, a curve that is roughly the shape of a parabola. From ground level to the vertex, the Gateway Arch is 630 feet tall. At ground level the legs are 630 feet apart. The legs extend 60 feet below ground level to anchor into bedrock. Given this information, what is the equation of a parabola that approximates the shape of the Gateway Arch? Assume that the origin of the coordinate system is at ground level midway between the legs of the arch. Give the equation in standard form y = ax 2 + bx + c. • Show less
