Question 878847: A natural bridge is a stone arch formed over a river or stream. The longest natural
bridge in the world is the Rainbow Bridge in Utah. If the origin is placed at one end
of the arch, the curve of the arch can be modelled by the equation
h=-0.0425d^2+3.57d
, where h represents the height and d represents the horizontal
distance both measured in meters.
a. What is the width of the arch at its base?
b. What is the maximum height of the arch?
