Scientists use the Beaufort wind scale to approximate wind speed. The formula is B= 1.69 sqrt(s+4.45) -3.49 where B is the Beaufort number and s is the speed in miles per hour. To the nearest mile per hour, what is the approximate wind speed if the Beaufort number is 6?

You have to be kidding.

Put this into the google search window:

(1.69*sqrt(6+4.45)) -3.49=

B = 1.68*sqrt(s+4.45)-3.49 = 6.

1.69*sqrt(s+4.45) = 6+3.49 = 9.49,

Divide both sides by 1.69:

sqrt(s+4.45) = 5.62,

Square both sides:

s+4.45 = 31.53,

S = 27.1 mi/hr.
