The income I, in dollars per month, for a fish farm depends on the fish population 
, measured in hundreds of fish. The relationship is
.
A: Make a graph of I versus n for fish populations up to 15 hundred fish.B: The expense E, in dollars per month, also depends on the population (again measured in hundreds). The relationship is
.
Add the graph of E versus n to the graph you made in part A.C: The fish farm is profitable if income exceeds expenses. What range of fish population results in a profitable fish farm?

Solve the problem.Tides go up and down in a 12.4-hour period. The average depth of a certain river is 10 m and ranges from 5 to 15 m. The variation can be approximated by a sine curve. Write an equation that gives the approximate variation y, if x is the number of hours after midnight and high tide occurs at 5:00 am.
A. y = 5 sin 
+ 10
B. y = 10 sin 
+ 5
C. y = 10 sin 
+ 5
D. y = 5 sin 
+ 10
