Figure 11-7b shows the rectangular pre-image It also shows the images of [A][M] and [B][M], where [A] is the transformation given in Review R4, part a, and [B] rotate and dilates the same as [A] but translates in the opposite direction. a. Write a matrix for transformation [B]. b. The two rectangles in Figure 11-7b form the first iteration for a more complicated geometric figure. In the second iteration, [A] and [B] are applied to both images in the first iteration. Perform these transformations and plot the resulting four images on graph paper. c. The figure that results from applying [A] and [B] iteratively infinitely many times can be plotted approximately using Barnsleys method. The result is shown in Figure 11-7c. Confirm on your grapher that the attractor in Figure 11-7c is correct. Write a paragraph describing the procedure used in Barnsleys method. Figure 11-7c d. On a copy of Figure 11-7c, circle two parts of the figure of different sizes, each of which is similar to the entire figure. e. On the copy of Figure 11-7c, plot the fixed point you found for transformation [A] in Review R4, part d. How does this fixed point seem to correspond to the fractal image? f. For the pre-image and the first three iterations, make a table showing the iteration number, the number of rectangles, the perimeter of each rectangle, and the total perimeter of the figure. From the pattern in the table, find the total perimeter of the 50th iteration. If the iterations were done infinitely many times, the result would be the strange attractor in Figure 11-7c. What is the total perimeter of the strange attractor? R
