At sea level, the weight of the atmosphere exerts a pressure of 14.7 pounds per square inch, commonly referred to as 1 atmosphere of pressure. As an object descends in water, pressure P and depth d are linearly related. In salt water, the pressure at a depth of 33 ft is 2 atms, or 29.4 pounds per square inch. (A) Find a linear model that relates pressure P (in pounds per square inch) to depth d (in feet). (B) Interpret the slope of the model. (C) Find the pressure at a depth of 50 ft. (D) Find the depth at which the pressure is 6 atms. (A) Choose the correct linear model below. OA. P=0.445d +29.4 OB. P=0.445d + 14.7 OC. P=0.03d+1 OD. P 2.245d-33

Transcribed Image Text:At sea level, the weight of the atmosphere exerts a pressure of 14.7 pounds per square inch, commonly referred to as 1 atmosphere of
pressure. As an object descends in water, pressure P and depth d are linearly related. In salt water, the pressure at a depth of 33 ft is 2
atms, or 29.4 pounds per square inch.
(A) Find a linear model that relates pressure P (in pounds per square inch) to depth d (in feet).
(B) Interpret the slope of the model.
(C) Find the pressure at a depth of 50 ft.
(D) Find the depth at which the pressure is 6 atms.
(A) Choose the correct linear model below.
O A. P=0.445d +29.4
O B. P=0.445d + 14.7
O C. P=0.03d + 1
O D. P=2.245d-33
