If a tank holds 4500 gallons of water, which drains from the bottom of the tank in 50 minutes, then Toricelli's Law gives the volume V of water remaining in the tank after t minutes as V = 4500(1-2/50t+1/2500t2)0 (a) 5 min 855 x gal/min
(b) 10 min 160 x gal/min
(c) 20 min 120 x gal/min
(d) 50 min gal/min
At what time is the water flowing out the fastest? t- 0 min At what time is the water flowing out the slowest? t50 min

b

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.

the ordered pairs for the given function are of the form
