Tabit ibn qorra (826 - 901) invented the following rule for finding amicable numbers if p = 3 2^n - 1 q = 3.2^n - 1 - 1 r = 9.2^2n - 1 - 1 are three prime numbers, then 2^n pq and 2^n r are pair of amicable number can you give two pairs of amicable numbers bigger than 100 using qorra's rule.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
