Math, a scuba driver.

Question

As a scuba diver descends deeper into the ocean, the water pressure increases. If  represents the depth (in feet) of the diver, then the relationship  gives the water pressure  in psi (pounds per square inch). Use this formula to answer the question.If the diver is  feet below the surface of water, what is the water pressure? Round to 2 decimal places, if necessary.The water pressure is  pounds per square inch.

Answer 1

P = 15 + .434x

P(50) = 15 + .434(50)

= 15 + 5(4.34)

= 15 + 21.70

= 36.70 psi, pounds per square inch
