Question

3) A rescue cable attached to a helicopter weighs 2 lb/ft. A 200-lb man grabs the end of the rope and is pulled from the ocean into the helicopter. How much work is done in lifting the man if the helicopter is 30 ft above the water? Give answer to nearest whole number. 4) A dome is in the form of a partial sphere, with a hemisphere of radius 40 feet on top and the remaining part of the sphere extending 20 feet to the ground from the center of the sphere. Find the surface area of the dome to the nearest square foot. Use substitution, integration by parts, trigonometric substitution, partial fractions and table of anti-derivatives to evaluate definite integrals and indefinite integrals. Use substitution to evaluate the integral. 5) ??¹ (6r dr) / ?(16 + 3r²) (Give your answer in exact form.)
