Question

An archway is modeled by the equation y = -2x2 + 8x. A rod is to be placed across the archway at an angle defined by the equation x − 2.23y + 10.34 = 0. If the rod is attached to the archway at points A and B, such that point B is at a higher level than point A, at what distance from the ground level is point B? A.8 units B.6 units C.5 units D.3 units

Answer 1

   A rod is to be placed across the archway at an angle defined by the equation x − 2.23y + 10.34 = 0. Hope this helps!
