The formula for całculating the number of calories burned while swimming at a moderate rate is c 2.9wt, where c represents the number of calories burned, w represents your weight in pounds, and t represents the time you swim in hours. how could you use this formula to you determine how long you should swim in order to burn a specific number of calories?

You would input your weight first then multiply 2.9 by your weight and put that as the denominator. For the numerator you would put how many colonies you want burnt. The answer to that is what you would put for t.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
