question 433

Multiple Choice

Solve the problem.
-Suppose $f ( x ) = 28.4 + 1.3 \log ( x + 1 )$ models salinity of ocean water to depths of 1000 meters at a certain latitude. $x$ is the depth in meters and $f ( x )$ is in grams of salt per kilogram of seawater. Approximate the salinity (to the nearest hundredth) when the depth is 383 meters.

• A) \(74.70 \mathrm {~g} / \mathrm { kg }\)
• B) \(31.76 \mathrm {~g} / \mathrm { kg }\)
• C) \(72.10 \mathrm {~g} / \mathrm { kg }\)
• D) \(- 25.04 \mathrm {~g} / \mathrm { kg }\)
