You can model that arch of a building entrance by using the equation y=-13 (x-5) (x-6), where x and y are measured in feet. The x-axis represents the ground. Find the width of the arch at the ground.

    Step-by-step explanation:

    The arch has the shape of an inverted parabola.

    It intersects the x-axis (the ground) at the roots of the equation

    -13 (x - 5) (x - 6) = 0

    Since the equation is already factored, we solve the equation by setting x - 5 equal to zero and x - 6 equal to zero and solving the equations.

    x - 5 = 0 or x 6 = 0

    x = 5 or x = 6

    The roots of the equation are x = 5 and x = 6.

    The width is the distance between x = 5 and x = 6.

    6 - 5 = 1

    The width of the arch at the ground is 1 unit.
