A cable hangs between two poles of equal height and 37 feet apart.(adsbygoogle = window.adsbygoogle || []).push({});

At a point on the ground directly under the cable and

x feet from the point on the ground halfway between the poles

the height of the cable in feet is

h(x)=10 +(0.4)( x^{1.5})

The cable weighs 15.1 pounds per linear foot.

Find the weight of the cable.

so i find h'(x) i square it and add one to find the length of the curve

i.e

(1+ h'(x)^2 ) ^(1/2)

my question is is that right? and what are the limits of integration??
