The temperature, T, in degrees Celsius, of the surface water in aswimming pool varies according to the following graph, where t is thenumber of hours since sunrise at 6 a.m.a) Find a possible equation for the temperature of the surface wateras a function of time.

Your swimming pool is square and 6.0 m on a side. It is 3.7 m deep in the morning. If the temperature changes by 37°C during the afternoon, how much does the depth of the water increase?

The swimming pool is open when the high temperature is higher than  . Lainey tried to swim on Monday and Thursday (which was   days later). The pool was open on Monday, but it was closed on Thursday. The high temperature was   on Monday, but decreased at a constant rate in the next   days.Write an inequality to determine the rate of temperature decrease in degrees Celsius per day,  , from Monday to Thursday.

A filled paddling pool was outside for an hour on a warm sunny day.During this time 2.81 MJ of energy was transferred to the 167 kg of water that started at 15.3 °C.Calculate the temperature of the water at the end of the hour.The specific heat capacity of water is 4200 J/kg°C._____ °CYou do not need to include units in your answer.Give your answer to 3 significant figures.I DON'T KNOWSUBMIT ANSWER

Two pools are being filled with water. To start, the first pool had 992 liters of water and the second pool was empty. Water is being added to the first pool at a rate of 16 liters per minute. Water is being added to the second pool at a rate of 48 liters per minute.Let x be the number of minutes water has been added.(a)For each pool, write an expression for the amount of water in the pool after x minutes.Amountofwaterinthefirstpool(in=liters)Amountofwaterinthesecondpool(in=liters)(b)Write an equation to show when the two pools would have the same amount of water.

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 70 degrees at midnight and the high and low temperature during the day are 76 and 64 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
