Question

The cable of a suspension bridge hangs in the form of a parabola. The supporting towels are 500ft. Apart and 50ft high and the cable at its lowest point is 10ft above the road way using the axes of the parabola as x axes. Find the equation of the parabola . Hence the length of the vertical cable 60ft from the centre of the bridge collect the nearest 10th of a foot

Answer 1

y = ax^2 + 10
a*250^2 = 50
Now, knowing a, find y at x=60

Answer 2

Thank you Sir, for your response
