Kenniya wrote 0.2( 4 + 1.4m - 2.1). Below was what she did. 1.) 0.2( 4 + 1.4m - 2.1).
2) 4.2 + 1.6m- 1.9
3) 4.2 - 1.9 + 1.6m
4) 2.3 + 1.6m
Which explains the first mistake Kenniya did?
O Her first mistake was in (2). She added 0.2 to each term instead of multiplying by 0.2
Her first mistake was in (2). She should have only added 0.2 to 4 instead of adding 0.2 to all 3 terms.
O Her first mistake was in (3), the 1.6m should be negative and 1.9 should be positive.
O Her first mistake was in (3), 1.9 should be the coefficient of m instead of 1.6.

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.
