Question

suppose f(x)=33.3+1.4 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 785 meters

Answer 1

100.47 because: 33.3+1.4 =34.7
785+1=786
34.7log(786)=100.47
