Question 878962: The curve of the arch on a bridge 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?
Please show your work.

h=-0.0425d^2+3.57d
a)d(-.0425d + 3.57) = 0, d = 3.57/.0425 = 84m is the width at the base
b)max height is at d = 42m
h(42) = = 74.97m
