Step-by-step explanation: the submarine starts at sea level, goes down 250 feet (-250). rises 80 feet (-170). descends 18 feet (-188). i don't know if this is correct or not. i haven't learned descending yet so idk- i think it's right i'm not sure. i don't know if this is right i'm so sorry.

the equation
describe a vertical parabola with vertex at point 
if 
-------> the parabola open Up and the vertex is a minimum
if 
-------> the parabola open Down and the vertex is a maximum
in this problem we have
---> because is positive (given problem)
so
The vertex is a minimum
therefore
<u>the answer is the option C</u>

There are many possible numbers. First, lets begin with the data there giving us. They are saying she wants to play a practice game so there at least needs to be 2 teams. It also says, that she wants 6 players on each team, nothing more and nothing less. So, for this we are going to use the 6 timetables.
6 x 2 = 12
6 x 3 = 18
6 x 4 = 24
6 x 5 = 30
6 x 6 = 36
There are also more numbers, but I am not doing those. But, for your first five, there can be 12, 18, 24, 30, and 36 students to be on the teams for the practice game.
