5. Use Newton's method to approximate the solution to In x = 1 + . Use x1 = 2 as your initial guess and use x4 as your approximation. Round to six decimal places. You must show your steps for credit. 6. Find the most general antiderivative of f (t) = cost + 1- 7. A farmer wants to build a rectangular fence that will enclose 120 ft. The two longer sides are to be made of plywood at a cost of $5 per foot, and the two shorter sides are to be made from wire, which costs $6 per foot. What are the dimensions of the fence that will minimize the cost? 8. Find the point on the line y = 3x - 4 that is closest to the origin
