A ball on a pendulum moves 30 cm on its first swing. Each succeeding swing it
moves 0.5 the distance of the previous swing. What is the total distance that the
ball moves before coming to rest? Write your answer in the box.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

a.)the line for function b is steeper
