Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is 
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become

we can arrange this properly to form a quadratic equation by grouping like terms.

solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
Answer:
me and my teacher say yes
Solution is x= -9.297 or -9.30 rounded and y= 5.6
Answer:
x=2.17
Step-by-step explanation:
14.88+x=17.05
We move all terms to the left:
14.88+x-(17.05)=0
We add all the numbers together, and all the variables
x-2.17=0
We move all terms containing x to the left, all other terms to the right
x=2.17
Pythagorean theorem(√82)^2 = 9^2 + x^2
x = 1 cm
15^2 = 9^2 + y^2
y = 12 cm.
12-1 = 11
Area = 9*11 = 99 cm^2
