Answer: The "independent variable" is the "time" (in hours) that is plotted on the "x-axis". Note the "time" (in hours) can be "manipulated" in the sense that is it "chosen" by the humans who are measuring the data (e.g. when to start, how many hours, and at what intervals.
The "dependent variable" is the measurement (in feet) above or below the sea level, and this is plotted on the "y-axis". These values cannot be "manipulated" in the sense that one cannot "choose" what value or measurement the tide level would be at any particular time.
Hope these answers—and explanations—are of help to you.

Answer:
b.
Step-by-step explanation:
B because the slope of f(x) is 1 yet the slope of g(x) is 1/3
The sine increases from 0 to 90 degrees and from 270 to 360 degrees
The sine decreases from 90 to 270 degrees
The cosine increases from 180 to 360 degrees
The cosine decreases from 0 to 180 degrees
Sine = 0 at 0 and 180 degrees
Cosine = 0 at 90 and 270 degrees
The equation for what the 2nd number of three consecutive numbers that equal to 414 is : x+(x+1)+(x+2)=414
Multiply and Simplify:
x+x+1+x+2=414
3x+3=414
Subtract 3 from both sides:
3x+3-3=414-3
3x=411
Divide three by both sides to get answer:
3x/3=411/3
x=137.
If you want to check if its correct add the three numbers that come next:
137+138+139=414.
