On Planet X, the height, h metres, of an object fired upward from the ground at 30m/s is described by the equation h = 30t – 6t 2 , where t seconds is the time since the object was fired upward. Determine (a) the maximum height of the object (b) the times at which the object is 36m above the ground (c) the time at which the object hits the ground (d) the equation in vertex form 2. The “Quadratics Cup” is a new coffee shop that sells various coffee- related items, but with a quadratics twist (like an equation written on your cup, or your caramel drizzle in the shape of parabolas, etc) The profit of this new coffee shop can be described by the equation P = –4n 2 + 64n – 112 where P represents profit in thousands of dollars and n represents the number of customers, in ten thousands.

### 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.
