2 Triangle RST with vertices R(-8, 2), S(-8, -6) and T (4, -6) is dilated by a
2
scale factor of 3. Which statement
is true?
A Triangle RST is smaller than
triangle R'S'T.
B The algebraic representation for
the dilation is (x, y) - (1.5x,
1.5y).
C Triangle RST is bigger than triangle
R'S'T'.
D Trianlge RST and R'S'T' are
congruent.

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.
