In certain deep parts of oceans, the pressure of sea water, P, in pounds per square foot, at 7d a depth of d feet below the surface, is given by the equation P=12+ 8 If a scientific team uses special equipment to measures the pressure under water and finds it to be 614 pounds per square foot, at what depth is the team making their measurements? If the pressure is 614 pounds per square feet, the team is measuring at the surface. feet below In certain deep parts of oceans, the pressure of sea water, P, in pounds per square foot, at 7d a depth of d feet below the surface, is given by the equation P=12+ 8 If a scientific team uses special equipment to measures the pressure under water and finds it to be 614 pounds per square foot, at what depth is the team making their measurements?
