1. The sides of a square 1 cm, have lines drawn between them connecting adjoining sides with their midpoints. This creates another square within the original and this process is continued indefinitely. (Given, Pythagoras theorem: Hypotenuse 2 = Perpendicular 2 + Base 2) a. Show the sequence of the sides for first 4 terms. [1] b. Show the sequence for the areas of the squares for first 4 terms. [1] c. Calculate the sum of the areas of the infinite squares.

The dash figure is a dilation if the original figure. find the scale factor. classify the dilation as an enlargement or a reduction

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.
