Gelneren [198K]

Answer:

The pressure at 50 feet is 2.51515 atm

Step-by-step explanation:

we are given equation as

p(d)=1+\frac{d}{33}

where

p(d) gives the​ pressure, in atmospheres​ (atm)

a depth d in the sea​ (d is in​ feet)

We are given

d=50 feet

So, we can plug d=50 and find p

p(50)=1+\frac{50}{33}

p(50)=2.51515atm

So,

The pressure at 50 feet is 2.51515 atm
