When an earthquake hits and creates a tsunami, the water first goes down from its normal level, and then rises an equal distance above its normal level, then returns to its normal level. a tsunami is approaching trig island and is modeled by: d = 10 sin [2π/15(t-7.5)]+11 where d= the water’s depth in meters and t= time in minutes since the earthquake. This model only works for one cycle! Using the equation, what is the maximum height of the tsunami wave?
