Write the definition of a class, swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool. Add appropriate constructors to initialize the instance variables. Also add member functions, to do the following: Determine the amount of water needed to fill an empty pool; the time needed to completely...
help me with these im getting lost 6) If a swimming pool is being filled, the volume in the pool is described by the equation V = (1 gal/s/s)t2 + (2 gal/s)t + 3 gal A) What is the volume flow rate (dv/dt) after 30 seconds? 6)A) B) What is the volume of the pool after 30 seconds? 6)B) 7) When a fire hose is first turned on the flow rate changes by the following equation one = (2 gal/s)t2...
A swimming pool is 40 feet long, 20 feet wide, 8 feet deep at the deep end, and 3 feet deep at the shallow end; the bottom is rectangular. If the pool is filled by pumping water into it at the rate of 40 cubic feet per minute, how fast is the water level rising when it is 3 feet deep at the deep end?

3. A sports writer wished to see if a football filled with helium travels farther, on average, than a football filled with air. To test this, the writer used 18 adult male volunteers. These volunteers were randomly divided into two groups of nine men each. Group 1 kicked a football filled with helium to the recommended pressure. Group 2 kicked a football filled with air to the recommended pressure. The mean vardage for Group 1 was "=300 yards with a...

(4). (8 pts). A soil profile is shown in below Figure. A uniformly distributed load Ao is applied at the surface of soil. Given the preconsolidation pressure is between swell index and compression index is: C C/6. The unit weight of water is: -9.38 kN/m. If U-98% we regard it as a completion of primary consolidation. We have taken the clay sample and done the Atterberg Limit test. For the liquid limit test, the result is as below. Please ơ'-926...
We are interested in the relationship between the compensation of Chief Executive Officers (CEO) of firms and the return on equity of their respective firm, using the dataset below. The variable salary shows the annual salary of a CEO in thousands of dollars, so that y = 150 indicates a salary of $150,000. Similarly, the variable ROE represents the average return on equity (ROE)for the CEO’s firm for the previous three years. A ROE of 20 indicates an average return...
