I need help with algebra 1? - sail boat diagram
Boat speed: The mathematical formulas help to developers in selecting the dimensions of the length of the pipe carried the water of a ship, sail area and displacement of so quickly.
Model:) The maximum speed n (in knots or nautical miles per hour, can be modeled several types of boat ride through the quadratic equation:
s ² = 16/9x
x = length of the water of the boat (feet).
Note: The waterline of the boat is the line in the main part of the boat that reaches the surface.
Problem: Draw a diagram of a boat and the water line, then use the equation for the speed of a boat length 32foot water line put in the form of radicals (in the form most easily). Then you find the speed to the tenth.
Ok, so I need help with this problem.

Since x is the length of the water of the boat (m), and I want to know sailboad the speed) with a length of 32 meters from the waterline in the form of radicals (in its simplest form, it suffices to replace x by 32 in the formula:
s ² = 16 / 9 (32)
s ² = 16 / 288
s ² = 1 / 18
However, to the square root of both sides
s = ± √ 1 / 18
In its simplest form
s = ± 1 / 3 √ 1 / 2
Then they want to know how fast the tenth, and of course, not used, the negative value, as is the speed to be a negative number.
Therefore, we use the positive or
x = 1 / 3 √ 1 / 2
x = 235
Tenth said
x = 2 knots
Have a good day!
