Find the length of the following tangent segments to the circles centred at O and O' whose radii are 5 and 3 respectively and the distance between O and O' is 12. 1) Find the tangent segment AB 2) Find the tangent segment CD Note: In #2, the line drawn from O to D was from my pencil, it's not part of the official problem.

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.
