If a completely full 5-gallon water jug is drained through aspigot, the depth is given by the formula below where t is thetime, in minutes, that the spigot is open and D is the depth, ininches, above the spigot. D = 0.265t2 ? 4.055t + 15.5 (a) Make agraph of D versus t. Include values of t up to 7.5 minutes. MapleGenerated Plot Maple Generated Plot Maple Generated Plot MapleGenerated Plot

(b) Calculate D(2). (Round your answer to two decimal places.)D(2) = Explain in practical terms what your answer means. The depthof the water is inches the spigot after the spigot has been open 2minutes.

(c) When will the water jug be completely drained? (Round youranswer to two decimal places.) min

(d) Does the water drain faster near the beginning or when thewater is mostly drained? The water drains faster near thebeginning. The water drains faster when it is mostly drained.
