As you complete the Four Situations worksheet tonight, please take a moment to write about WHY the four equations fit each situation. Pay close attention to the STRUCTURE of the equations.
Tonight, please complete problems 1 – 5 on the worksheet Ten Situations.
Be sure to label your axes with specific variable names.
Be sure to come to class tomorrow with (at least) 10 quantitative variables for 3 of the situations on the Making Decisions I worksheet.
We will use these variables to build functions in class tomorrow!
Today in class we began to dilate shapes without using the coordinate plane.
Please continue to extend your study with questions 6 – 87 through 90.
Tonight please answer the following questions about translations and dilations for homework:
6 – 66, 6 – 67, 6 – 78, 6 – 80
When you multiply both the x and y coordinate by the same number, that number is called a scale factor. The new image is called a dilation.
When you only multiply the x OR y coordinate by a number, then you are performing a vertical/horizontal stretch/shrink. The new shape is not a dilation, as it is not similar to the original shape.
Your homework tonight was problems 6-58 and 6-59.
Today we wrapped up our work on rigid motion.
Please complete problems 6 – 26 through 6 – 28 over the weekend for homework. On Monday we will begin reviewing translations.
Tonight, please complete problems 6 – 18 through 6 – 20 for homework.
Focus on clear (precise) language to describe your transformations.
