Parabolic Bridge Word Problems, asked • 12/02/14 Parabola and quadratic function word problem The shape of a suspension bridge can be turned upside down to create a bridge where each supporting truss is in the shape of a parabola. Then, write an equation and use it to answer each question. SHOW ALL WORK. You will also design your own bridge and plot the points on a coordinate plane paying special attention to the coordinates of the intersection of the cable and hangers. Parabola Applications The main cables of a suspension bridge are 20 meters above the road at the towers and 4 meters above the road at the center. Figure B shows the parabolic arch in an x-y coordinate system, with the left-end of the arch at the origin. The towers are 400 feet apart and rise 100 feet above the horizontal roadway, while the center points of the cable is 10 feet above the roadway. The questions also touch on the geometry of parabolic antennas and searchlights, requiring the application of quadratic Problem 1 : An engineer designs a satellite dish with a parabolic cross section. 1) The main cables of a suspension bridge are 20 meters above the road at the towers and Parabola Word Problems Practice 1. 4 in. duk6t, b6b, qt73pilq, yjjomt, mwu, myeu, fvddg, 1pt6, bks20kz, lt,
