In certain deep parts of oceans, the pressure of sea water,
P
,
in pounds per square foot, at a depth of
d
feet below the surface, is given by the following equation:
P
=
14
+
4
d
13
If a scientific team uses special equipment to measures the pressure under water and finds it to be 338 pounds per square foot, at what depth is the team making their measurements?
Answer: The team is measuring at
feet below the surface.
how about typing that so we can actually read it?
In any case, just plug in your numbers and solve for d.
