A hotel entrance makes a parabolic arch that can be represented by a quadratic function, f (x) = - x^2 - 4x + 12, where y is the height of the arch and x is the distance from wall to wall in feet. What is the distance between the two walls of
the arch?

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
