Jennifer starts with a population of 100 amoebas that doubles in size every minute for a number of minutes, m. she writes the expression 100(2m) to find the number of amoeba after m minutes. nathan starts with a population of 10 amoebas that increases 40% in size every minute for a number of minutes, m. he writes the expression (1+0.4)m to find the number of amoeba after m minutes. use the drop-down menus to explain what each part of jennifer's and nathan's expressions mean.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
