Solve the problem.
-The function $\mathrm { P } ( \mathrm { d } ) = 1 + \frac { \mathrm { d } } { 33 }$ gives the pressure, in atmospheres (atm), at a depth $\mathrm { d }$ feet in the sea. Find the pressure at 30 feet.
A) $\frac { 21 } { 11 } \mathrm {~atm}$
B) $\frac { 1 } { 11 } a t m$
C) $\frac { 10 } { 11 }$ atm
D) $\frac { 31 } { 33 } \mathrm {~atm}$

Quizplus · Accepted Answer

To find the pressure at 30 feet, substitute $d = 30$ into the given function: $P(30) = 1 + \frac{30}{33} = 1 + \frac{10}{11} = \frac{21}{11}$ atm.

Solve the Problem P(d)=1+d33\mathrm { P } ( \mathrm { d } ) = 1 + \frac { \mathrm { d } } { 33 }P(d)=1+33d​

Solve the Problem $\mathrm { P } ( \mathrm { d } ) = 1 + \frac { \mathrm { d } } { 33 }$
