# What is the work done in using a cable that weighs 2 pound per foot to lift a weight of 800 pounds a distance of 500 feet?

Load = 800lb

So total load = 1000 + 800 = 1800lb.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- If #y=ln(2x^2-6x)#, then what is #dy/dx#?
- What is a general solution to the differential equation #dy/dx=10-2y#?
- How do you find the exact area of the surface obtained rotating the curve about the #x#-axis of #y=sqrt(8-x)#, #2<=x<=8#?
- How do you find the length of the curve #y=sqrtx-1/3xsqrtx# from x=0 to x=1?
- How do you find the volume of the solid obtained by rotating the region bounded by the curves #y=x#, #x=0#, and #y=(x^2)-6# rotated around the #y=3#?
