Question 9 of 16
Maria is training for a sprint-distance triathlon. She plans on cycling from her house to the library, on the grid with a scale of miles. If the cycling portion of the triathlon is 12 miles, will Maria have cycled at least 2/3 of that distance during her bike ride? Justify your argument. The library is at (4,9) Maria’s house is at (9,2)

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.

The answer is idk yo

Area of circle = pi * radius^2radius is given to be 1/2 inchespi * (1/2)^2 = pi/4 inches^2 = 0.785 inches^2
