DON’T GUESS , 2 points for each right answer, minus 2 points for each wrong answer. (a) True or False : Suppose that two cars are racing. After t seconds the first car is traveling at velocity v 1 ( t ) feet per second and the second car at v 2 ( t ) feet per second. If the average value of v 1 ( t ) on [0 , 60] is equal the average value of v 2 ( t ) on [0 , 60], then the cars have travelled the same distance after 60 seconds. (b) True or False : integraldisplay xe x dx = e x ( x - 1) + C. (c) True or False : y = 1 + e 2 x satisfies the differential equation y = 2 y.

### 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.
