Solve the Problem $S$ Of Ocean Water at a Given Depth $d$

question 326

Multiple Choice

Solve the problem.
-Suppose that the salinity $S$ of ocean water at a given depth $d$ is modeled by the equation $\mathrm { S } ( \mathrm { d } ) = 28.4 + 1.3 \log ( \mathrm { d } + 1 )$ , where $\mathrm { S }$ is measured in grams salt per kilogram water and $\mathrm { d }$ is measured in meters. What is the salinity when the depth is $17 \mathrm {~m}$ ? Round your answer to the nearest hundredth.

• A) \(34.35 \mathrm {~g}\) salt \(/ \mathrm { kg }\) water
• B) \(30.03 \mathrm {~g}\) salt/ \(/ \mathrm { kg }\) water
• C) \(- 26.77 \mathrm {~g}\) salt/ \(/ \mathrm { kg }\) water
• D) \(36.95 \mathrm {~g} \mathrm { salt } / \mathrm { kg }\) water
