Practice Test #5 MAC2312 Directions: Use this practice test as a guide for your study for Test #5. This exam is not comprehensive, so study your quiz, class notes and homework problems in addition to completing this exam. Solutions are posted on the course website under “Solutions”. 1) For the parabola ) 1 ( 12 ) 3 ( 2 x y , find the vertex and focus as ordered pairs, find the equation of the directrix, and sketch. Label all information on your sketch. 2) Find the standard equation of the hyperbola given by 0 100 40 36 4 9 2 2 y x y x . 3) Sketch the plane curve given by the parametric equations 7 5 t x , 4 3 t y for 2 3 t . Use a table of values for x, y and t, and show appropriate directional arrows to indicate increasing t values. 4) For the equations given in problem #4, eliminate the parameter to find a rectangular equation where y is a function of x. Simplify completely, finding a common denominator. 5) Find a set of parametric equations that represent the graph of

### 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.

• 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.
