The function,p(d)=1+d/33, gives the pressure in atmospheres(atm), at a 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.

Solve

p = 1 + d/33 when d = 120 ft

The answer will be in atm

To find the pressure at 120 feet, we need to evaluate the function p(d) = 1 + d/33 at d = 120.

Substituting d = 120 into the function, we have:

p(120) = 1 + 120/33

We can simplify this expression by finding the value of the fraction 120/33:

120 divided by 33 equals 3.636363... (repeating decimal).

Now, add 1 to this result:

1 + 3.636363... = 4.636363...

Therefore, the pressure at 120 feet is approximately 4.636363... atmospheres (atm).
