Question 578272
A water tank is h feet high.
 Water is flowing from the water tank with a velocity V feet per second.
 The model representing the relationship between the velocity and height is given by:
 V = {{{6sqrt(h)}}}
:
A). find the height of a water tank that provides a water flow of 60 feet per second.
V = 60 ft/sec, therefore
{{{6sqrt(h)}}} = 60
divide both sides by 6
{{{sqrt(h)}}} = {{{60/6}}}
{{{sqrt(h)}}} = 10
square both sides
h = 10^2
h = 100 ft is the height for a velocity of 60 ft/sec
:
B). find the velocity of the water flow when the height is 130 feet.
 Round your answer to two decimals.
h = 130, therefore:
V = {{{6sqrt(130)}}}
V = 6 * 11.40
V = 68.41 ft/sec
