the function, p(d) =1 d
+ ____
33 gives the pressure, in atmospheres (atm), at an depth d in the sea (d is in feet). Note that p(0)=1 atm, p(33) =2 and so on. find the pressure at 120 feet.
The pressure at 120 fee is ____ atm.
To find the pressure at 120 feet, we need to evaluate the function p(d) at the given value of d. In this case, the function is defined as:
p(d) = 1 + d/33
To find p(120), we substitute d = 120 into the equation:
p(120) = 1 + 120/33
Now we can calculate the pressure at 120 feet:
p(120) = 1 + (120/33) ≈ 1 + 3.64 ≈ 4.64 atm
Therefore, the pressure at 120 feet is approximately 4.64 atm.
