Pre-Calculus Summer Assigment To All Future Pre-Calculus Students- You have successfully completed Algebra 2. It is now time to prepare for Pre-Calculus. This assignment will be the first homework grade for the class. Complete the packet prior to the first day of school. The packet includes topics covered in Algebra 1 and Algebra 2. There are no new concepts included in this packet. If you are unable to answer a question, do not skip it! Research the topic on the internet and make a solid effort at attempting the problem. The packet will be graded on effort and not accuracy of your answers. Therefore, answer all questions. Work must be included to receive full credit. When we return to school in September, we will spend class time going over the packet in detail and provide additional problems, if necessary on any specific topic. Students will be assessed on the material contained in this packet. Enjoy your summer and we look forward to meeting you in the Fall. The Pre-Calculus Teachers
Name Pre-Calculus Date Summer Assignment Directions: Please do all work on a separate sheet of paper. Number all problems on the separate sheet so it is easy to follow. Place the solution on the line provided. It is strongly recommended that the problems be completed without the aid of a calculor, unless directed to use one. You may use the calculator to check your work. Good Luck!

Mr. Goodman, who knows a lot about physics, is going to fire a rocket to start off this year s Battle of the Classes. He has done testing on the rocket to ensure it will not hit any students. If the rocket is launched upwards with an initial velocity of 200 feet per second, its height h(t) (in feet) can be found by the function h(t) = -16t 2 + 120t, where t is the number of seconds since it was launched. 56) How long will it take for the rocket to reach its highest point? 57) What is the maximum height that the rocket will reach?

For a woman, the normal systolic blood pressure (in millimeters of mercury) is given by the function P =.01x 2 +.05x + 107, where x is the woman s age. Use this function to find the age of a woman whose systolic blood pressure is measured to be 121 millimeters of mercury. (Hint: Use the Quadratic Formula)
