Answer:
9.17 ft
Step-by-step explanation:
Put x=12 in the equation and evaluate. (The sine argument is in degrees.)
y = 1.5·sin(25.72(12 +1.5)) +9.5 = 1.5·sin(347.22) +9.5
y = -0.33 +9.5 = 9.17
The water will be 9.17 feet deep at noon.
Step-by-step explanation:
First we need to isolate the y, by dividing -4 on both sides. This will give you y = 1/4x - 5.
Now you can properly graph the equation:
Since -5 is the y-intercept (the point in which the line intercepts the y-axis), we will place our first point at (0,-5) on the graph.
In order to find the next point, we will use the slope of the line and do rise/run. So we will go upwards 1 unit and to the right 4 units.

Hope this helps you :)
