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.

Let
we know that
The perpendicular bisector pass through the midpoint of AB
step 1
Find the midpoint AB
step 2
Find the slope of the given line AB
The formula to calculate the slope between two points is equal to
substitute
step 3
Find the slope of the perpendicular bisector
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
we have
----> slope of the given line
substitute in the formula
step 4
Find the equation of the perpendicular bisector
we know that
The equation of the line into point slope form is equal to
we have
substitute
