Light Bulb Data Block2, Block3

Use the TI "LIGHT" program from the Real World Math series to collect data for the intensity of a light as the distance varies from 1.0 to 2.0 meters.

D(m)   Intensity 1   0.127 1.1   0.105 1.2   0.09 1.3   0.076 1.4   0.071 1.5   0.063 1.6   0.049 1.7   0.042 1.8   0.038 1.9   0.036 2   0.034		Right click here to download the data as a TI-83 program.

The data demonstrates the inverse square law for intensity of a light vs distance. The intensity is inversely related to the square of the distance.
What does the model predict the intensity would be at 0.5m?
What distance would be required for an intensity of .2?
