2. The Gateway Arch in St. Louis was constructed using the equation for the central curve of the arch, where x and y are measured in meters and |x| < 91.20. Set up an integral for the length of the arch and use your calculator to estimate the length correct to the nearest meter.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

it is x equals 3   plese mark me really need it
