Math Problem Statement
According to a certain organization's rules, the maximum sail area S for a boat with length L (in meters) and displacement D (in cubic meters) is determined by the equation given below. Upper L plus 1.25 Upper S Superscript one half Baseline minus 9.8 Upper D Superscript one third Baseline equals 16.296 Find S for a boat with length 20.52 m and displacement 17.72 mcubed.
Solution
The equation given is:
You need to find when the length and the displacement .
Let's substitute the known values of and into the equation and solve for .
First, calculate , and then solve for . I'll handle the calculations step by step.The sail area for the boat with a length of 20.52 meters and a displacement of 17.72 cubic meters is approximately .
Would you like more details on the steps, or do you have any questions?
Here are some related questions to expand your understanding:
- How does the displacement affect the sail area in the equation?
- What happens to the sail area if the length of the boat is increased?
- Can you solve for if the sail area and displacement are known?
- How would the formula change if a different coefficient is used for ?
- What is the physical meaning of the cube root of displacement ?
Tip: When solving for variables under a square root, it's important to isolate the square root term before squaring both sides to avoid errors.
