Problems 1. The following equation describes the process of warming a hot tub by adding hot water: IN-ISTART) where is the temperature of the water in the hot tub is the temperature of the water flowing into the hot tub, (130°F) is the initial temperature of the water in the hot tub (65°F) is the hot-water flow rate (5 gpm) is the volume of the hot tub (500 gallons), and is the elapsed time since the hot water started flowing...

Water is drained from a hot tub that holds 1600 L of water. It takes 2 h for the water to drain completely. The volume of water in the tub is modelled by ?(?) = 1 9 (120 − ?) 2 , where ? is the volume in litres at ? minutes and 0 ≤ ? ≤ 120. (a) Find the average rate of change during the first 30 minutes. [3 pts] (b) Determine the instantaneous rate of change after...
