The hull speed of a boat when given by the function v = 1.34√l, makes the expression represent the speed of Santa Monica, v = a√b, with <u>a = 1.34</u>, and <u>b = ln - 10</u>, where lₙ is the length of the Nina Pinta. The restriction on lₙ is that <u>lₙ > 10</u>.
In the question, we are asked to express the speed of the boat of Santa Monica in terms of the length, lₙ of the Nina Pinta.
We are informed that the function is represented as v = a√b, for the speed of Santa Monica.
We are given that the hull speed of a boat of length l is given as v = 1.34√l.
Comparing, the speed of Santa Monica v = a√b, to the general formula v = 1.34√l, we get:
a = 1.34, and
b = the length of the boat of Santa Monica.
The length of the boat of Santa Monica is 10 ft. shorter than of Nina Pinta.
Thus, b = lₙ - 10, where lₙ is the length of the boat of Nina Pinta.
Since b has to be positive, as the function involves square root over b, lₙ - 10 > 0, or, lₙ > 10, is the restriction on the length of the boat of Nina Pinta.
Thus, the hull speed of a boat when given by the function v = 1.34√l, makes the expression represent the speed of Santa Monica, v = a√b, with <u>a = 1.34</u>, and <u>b = ln - 10</u>, where lₙ is the length of the Nina Pinta. The restriction on lₙ is that <u>lₙ > 10</u>.
