12. A hot air balloon is rising vertically from a level field from a point that is 500 feet from an observer. At the instant, when the angle of elevation is , the angle of elevation is increasing at a rate of 0.08 radians per minute. How fast is the balloon rising at that moment? 

13. Use the Newton’s method to find the solution of the equation with 3 as the starting guess, show at least five values of the iterations. 

14. A power company needs to lay a cable from point A on one bank of an 800-foot wide straight river to point B on the opposite bank 1600 feet downstream. The power company will choose a point C on the same side of the river as B, and will lay a cable underwater from A to C and on land from C to B. It costs $3 a foot to lay the cable on land and $5 a foot to lay it underwater.

Where the point C should to be chosen to minimize the total cost and what is the minimum cost?
