**A student wishes to approximate**

A student wishes to approximate by using Newton’s Method to approximate a zero of f(x) = x2 – 12. If she chooses c1 = 4, then c3 will be ? Give your answer in fraction form.

3
On the same side of a straight river are two towns and the townspeople want to build a pumping station, S, that supplies water to them. The pumping station is to be at the rivers edge with pipes extending straight to the two towns. The distances are shown in the figure. Where should the pumping station be placed to minimize the total length of pipe? x = 4/5 miles

**Sand is pouring from a pipe at the rate of 16 cubic feet per second**

Sand is pouring from a pipe at the rate of 16 cubic feet per second. If the falling sand forms a conical pile on the ground whose altitude is always ¼ the diameter of the base, how fast is the altitude increasing when the pile is 4 feet high?

5
**Find Consider the curve given by xy2 – x3y = 6.**

Find all points on the curve whose x-coordinate is 1, and write an equation for the tangent line at each of these points. Find the x-coordinate of each point on the curve where the tangent line is vertical.

**A spherical balloon is inflating at a rate of 27π in3/sec**

A spherical balloon is inflating at a rate of 27π in3/sec. How fast is the radius of the balloon increasing when the radius is 3in.? How fast is the surface area of the balloon increasing when the radius is 3in.?

7
If an open can with volume 16 cubic inches is to be made in the form of a right circular cylinder, find the height and the radius if the least amount of material is to be used in its manufacture.
