Use the procedure for solving variation problems to solve the exercise.y varies jointly as a and b and inversely as the square root of c. y = 14 when a = 2, b = 5, and c= 25. Find y when a = 5, b = 4, and c= 16.Find y when a = 5, b = 4, and c= 16.y =(Type an integer or a decimal. Do not round until the final answer. Then round to the nearest tenth as needed.)
