  1. Does the height of the water increase by the same amount each minute? Explain how you know.
  2. Does the height of the water increase by the same factor each minute? Explain how you know.

  1. The height of the water increases by the same amount each minute. This is because all the values in the table have a common difference of 0.6 cm.
  2. The height of the water does not increase by the same factor because there is no common ratio between the values. There is a slight difference

          \frac{49.6}{49} = 1.0122

          \frac{50.2}{49.6} = 1.0120

          \frac{50.8}{50.2}= 1.0119
