Unformatted text preview: p(x) = x3 − 2 and then showing p has no rational zeros. (You’ll need the Rational Zeros Theorem, Theorem 3.9, in order to show this last part.) 5.3 Other Algebraic Functions 323 11. With the help of your classmates, generalize the previous exercise to show that irrational number provided that cn is not a rational number. √ n c is an 12. Suppose Fritzy the Fox, positioned at a point (x, y ) in the first quadrant, spots Chewbacca the Bunny at (0, 0). Chewbacca begins to run along a fence (the positive y -axis) towards his warren. Fritzy, of course, takes chase and constantly adjusts his direction so that he is always running directly at Chewbacca. If Chewbacca’s speed is v1 and Frity’s speed is v2 , the path Fritzy will take to intercept Chewbacca, provided v2 is directly proportional to, but not equal to, v1 is modeled by y= 1 2 x1+v1 /v2 x1−v1 /v2 − 1 + v1 /v2 1 − v1 /v2 + v1 v2 2 − v1 2 v2 (a) Determine the path Fritzy will take if he runs exactly twice as fast as Chewbacca; that is, v2 = 2v1 . Use your calculator to graph this p...

    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.
