This examination has 11 problems and 10 printed pages. (There are '2 additional pages for scrap work.) Make sure your examination copy is complete before you begin work. There are 200 points available on this examination. The point values are indicated for each of the 11 problems. All work for which you seek credit must be written on the printed pages in the appropriate places. The last two scrap pages of this booklet will not be graded! All answers must be justiﬁed. Calculators may be used to check your answers but not to justify them. Do not write below this line 1 7. 2 8. 3 9 4 10. 5 11. 6. Total 2 1. (8 points each) Evaluate the following limits.

Water is leaking from the bottom (the vertex) at the rate of 50 cubic feet per minute. How fast is the water level falling when the water is 5 feet deep? The volume V of a cone is given by V 2 énrzh where r is the radius of the cone and h is its height. 6 6. (15 points) A right triangle has one vertex at the origin, its right angle on the positive :L'-axis, and its third vertex P on the graph of y = ( + a: P which causes the triangle to have maximum area.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

Dana University of Pennsylvania ‘17, Course Hero Intern

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
