The Gateway Arch in St. Louis was designed by Eero Saarinen and was constructed using the equation below for the central curve of the arch, where x and y are in meters and |x| 91.20.
y = 211.49 - 20.96cosh ( 0.03291765x )
(a) What is the height of the arch at its center? (Round the answers to two decimal places.)
(b) At what points is the height 110 m?
x =___________________ m (smaller value)
x =___________________ m (larger value)
(c) What is the slope of the arch at the points in part (b)?
y' =_____________ (smaller x value)
y' =_____________ (larger x value)
