Answer:
its 36 gallons
Step-by-step explanation:
Focus of the parabola is (-5,5) and directrix is y = -1.
Let's assume a point (x,y) on parabola.
According to definition of parabola, the distance between point (x,y) and focus (-5,5) would be same as the distance between the point (x,y) and directrix y = -1.

Hence, option D is correct, i.e. f(x) = one twelfth (x + 5)2 + 2.
If that is the position function, velocity is the derivative of it.
v(t)=-14
Since velocity is a constant -14, the value of t has no bearing on the result. The instantaneous velocity is always -14.
The scientific notation is 37.5×10^-6
