The graph below relates y, the distance Kelly walked, to x, the amount of time that Kelly walked. 1,200
800
400
O
Time (minutes)
Part A: What is the value of y when x = 1?
Part B: Explain how you can use your answer to Part A in # 16 above to predict, within the context of the situation, where Kelly is at time t minute

The probability that a tutor will see 0, 1, 2, 3, or 4 students is given below determine the probability distribution's missing value.

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.

Write as a product of two polynomials. 2(3–b)+5(b–3)^2
