You wrote the expression on the left side of the America’s Cup rule in radical form L+1. 25 √5 -9. 8 3√0/0. 686 , now use this form of the expression to write a function () that gives the value of the expression for the new yacht in terms of the displacement. a) To write the function, what variables will you replace with specific values? What are those values?

b) Write and simplify the function.

c) Describe how you could use the function to write and solve an equation to find the displacement that makes the value of the left side of the America’s Cup rule exactly 24

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem.
