The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
Convert the given function to vertex form
Factor the leading coefficient
Complete the square
Rewrite as perfect squares
------> equation in vertex form
The vertex is the point (2,6)

We can do this in a few steps.
First: If it is 300 ounces per second then how many pounds per second?
1 ounce is 1/16 of a pound.
So we multiply 300 by 1/16.
300 x 1/16 = 300 ÷ 16 = 18.75
Now we know: 300 oz/sec equals 18.75 lbs/sec
But, we want to know how many lbs per minute (lbs/sec)
We need to calculate how many seconds are in a minute.
1 minute = 60 seconds.
We know how many lbs per second.
If we want to know how many lbs per minute, we multiply # of pounds per seconds by 60.
# pounds per second x 60 = # pounds per minute
# pounds per second: 18.75
18.75 x 60 = # lbs/min
18.75 x 60 = 1125
This means that 300 oz/sec => 1125 lbs/min
Comment: Wow, you have at least 390 math problems. That is insane! I've never had to do "the 390th math problem"!
