An employee at a garden center fills a water tank once a day around noon to a height of 20 inches. The function M models the height of the water in the tank, \small M\left(x\right), in inches, \small x seconds after 12:00 p. m. on Monday as it fills. The function T gives the height of the water in the tank, \small T\left(x\right), in inches, \small x seconds after 12:00 p. m. on Tuesday as it fills. Here are the equations and graphs of M and T. On Wednesday, the employee gets a second hose and is able to fill the tank twice as fast as Monday. They start filling the tank at exactly 12:00 p. m. The function W models the height of the water in the tank, \small W\left(x\right), in inches, \small x seconds after 12:00 p. m as it fills. Write an algebraic equation for W. \small M\left(x\right)=5\sqrt[3]{x} \small T\left(x\right)=5\sqrt[3]{x-10}
