suppose that the salinity S of ocean water at a given depth d is modeled by the equation S(d)=31.7+1.5log(d+1), where
S is measured in grams salt per kilogram water and
d is measured in meters.
what is the salinity when the depth is 931 m? Round your answer to the nearest hundredth.
:
S(d)=31.7+1.5log(d+1)
d = 931
S(d) = 31.7+1.5log(931+1)
S(d)=31.7+1.5log(932)
find the log of 932
S(d)=31.7+1.5(2.969
S(d)=31.7+4.54
S(d) = 36.15 gr of salt in one kilogram of water
