1. ## Function P(d)

Function P(d) 1 + d/33
P (0) = 1 atm, P (33) = 2 atm.

Find pressure at 160 feet

160 feet is ( ) atm.

2. $P(d) = 1 + \frac{d}{33}$
P(0) is given by: $P(0) = 1 + \frac{0}{33} = 1 + 0 = 1$
P(33) is given by: $P(33) = 1 + \frac{33}{33} = 1 + 1 = 2$
So, P(160) is given by: $P(160) = 1 + \frac{160}{33} = 1 + 4.85 = 5.85$
