An arch is in the form of a parabola given by the function h = -0.06d^2 + 120, where the origin is at ground level, d meters is the horizontal distance and h is the height of the arch in meters. Graph this function on your graphing calculator then complete the following statements.
The height of the arch is: m
The width to the nearest meter, at the base of the arch is m

See attachment for graph

The height of the arch is: 120 m

The width to the nearest meter, at the base of the arch is 22 m

Step-by-step explanation:

Given

Solving (a): The graph

See attachment for graph

Variable h is plotted on the vertical axis while variable d is plotted on the horizontal axis.

Solving (b): The height

The curve of opens downward. So, the maximum point on the vertical axis represents the height of the arch,

Hence:

Solving (c): The width

The curve touches the horizontal axis at two different points.

The absolute difference of both points represents the width.

So:

Hence:
