Hello
x² + y² - x - 2y - 11/4 = 0
(x²-x) +(y²-2y)-11/4 = 0
(x-0.5x)²-(1/2)² + (y-1)² -1² -11/4=0
(x-0.5)² +(y-1)² = (1/4)+1+(11/4)
= (1/4)+(4/4)+(11/4)
(x-0.5)² +(y-1)² =4²

The answer is D. All you have to do is graph the equation, and you will have the vertex and the roots. By the way, you can rule out B and C because those two do not follow the rules of a quadratic. Also, A and B have the wrong axis of symmetry, because the rocket lands after 10 seconds.
