I need you to post a diagram.
However, you are describing a 30 60 90 triangle and here is a good page to learn about those: http://www.1728.org/trig2.htm
Answer:
v= 141.37
Step-by-step explanation:
π · 3^2 · 15/ 3
=141.37167
Your answer is -2 as the axis of symmetry is at -b/2a. So if you were to expand the equation, you would get y= x^2/4 +x -6 where b is 1 and 2a is ½ . Therefore -1 / ½ gives you -2
It would be around 138 minutes which is 2 hrs and 18 min so it would be C).
