Kayley needs to find the area of a circle. Which process should she use? She should multiply the diameter by 2 and then multiply the result by 3.14. She should multiply the radius by 2 and then multiply the result by 3.14. She should square the diameter and then multiply the result by 3.14. She should square the radius and then multiply the result by 3.14.

Me, prove a quadrilateral with vertices g(1,-1), h(5,1), i(4,3) and j(0,1) is a rectangle using the parallelogram method and a rectangle method.

In which form is the following function written? y = - 2(x – 3)(x + 5)

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.
