8. State the order and type of each transformation of the graph of the function ƒ(x) = 4(x + 9)2 as compared to the graph of the base function. a. right 9 units, vertical stretch by a factor of 4
b. left 9 units, vertical stretch by a factor of 4
c. vertical stretch by a factor of 4, left 9 units

What properties allow transformation to be used as a problem solving tool

Consider a cube that has sides of length l. now consider putting the largest sphere you can inside this cube without any point on the sphere lying outside of the cube. the volume ratio -volume of the sphere/ volume of the cube is 1. 5.2 × 10−1 2. 3.8 × 10−1 3. 1.9 4. 2.5 × 10−1 5. 3.8

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
