Question

when you dive below the surface of the water, the pressure increases. you can feel this in your ears when you dive to the bottom of a deep swimming pool or spring. the function that describes this relationship is $p(d)=14.5 + \frac{29}{66}d$, where $d$ is the depth in feet below the surface of the water and $p$ is the pressure in pounds per square inch (psi). what is the pressure at the surface of the water? select the correct units from the second box. at what depth is the pressure exactly double the pressure at the surface of the water? select the correct units from the second box. what is the pressure at a depth of 231 feet? $p(231)=$ what is the pressure at a depth of 297 feet? $p(297)=$ which of the following is the graph of the function $p(d)$.

Explanation:

Answer:

(a) 14.5 PSI
(b) 33 feet
(c) 118 PSI
(d) 149.5 PSI
(e) A graph with the x - axis labeled "Depth \(d\) (feet)" and y - axis labeled "Pressure \(P(d)\) (PSI), y - intercept at 14.5, and a positive - slope line since the function \(P(d)=14.5+\frac{29}{66}d\) is a linear function with a positive slope \(\frac{29}{66}\)
