Question

A tank holds 200 gallons of water, which drains from a leak at the bottom, causing the tank to empty in 40 minutes. Toricelli's Law gives the volume of water remaining in the tank after t minutes as V (t) = 200 (l - t/40)2 Find V-1. What does V-1 represent? V-1 represents rate at which the tank leaks. V-1 represents the volume of water that has leaked. V-1 represents time that remains for the tank to be emptied. V-1 represents time that has elapsed since the tank started to leak. Find V -1(14). Round your answer to the tenths place. What does your answer represent? In 10.6 minutes the tank has drained 14 gallons of water. In 29.4 minutes the tank has drained 14 gallons of water. In 10.6 minutes the tank has drained to just 14 gallons of water. In 29.4 minutes the tank has drained to just 14 gallons of water. The relationship between the Fahrenheit (F) and Celsius (C) scales is given by F(C) = 9/5 C + 32. Find F -1. F-1(C) = What does F -1 represent? F -1 represents the Fahrenheit temperature that corresponds to a Celsius temperature. F -1 represents the Celsius temperature at time t. F -1 represents the Celsius temperature that corresponds to a Fahrenheit temperature. F -1 represents the difference in degrees between Celsius and Fahrenheit. Find F -1 (50). F -1 (50) = degree What does your answer represent? The Fahrenheit temperature that corresponds to 50 degree Celsius. The difference in temperature between 50 degree Fahrenheit and its Celsius equivalent. The Celsius temperature that corresponds to 50 degree Fahrenheit. The Celsius temperature after 50 minutes. A spherical balloon is being inflated. The radius of the balloon is increasing at the rate of 6 cm/s. Find a function f that models the radius as a function of time t. f(t) = Find a function g that models the volume as a function of the radius r. g(r) = Find g o f. g o f =
