Bella and Marco described the sequence of transformations in different ways. Bella's Sequence
Marco's Sequence
1. a dilation of trapezoid K by a scale factor of ģ with the
origin as the center of dilation
2. a rotation of 18 about the origin
3. a translation of 1 unit down
1. a reflection of trapezoid K across the x-axis
2. a dilation by a scale factor of with the origin as the
center of dilation
3. a translation of 1 unit down
Which sequence or sequences are correct and why?
Only Bella is correct
Only Marco is correct.
O Both Bella and Marco are corect because both chose the correct scale factor for the ditation and both describe other
transformations that could be used
Neither Bella nor Marcos conectbec
clor they chose for the stations incorrect

The scale for a map is 20 miles = 1/2 inch. the distance between two towns on the map is 3 3/4 inches. what is the actual distance between these towns? 150 miles 38 miles 75 miles 135 miles

Part one: measurements 1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project. name relationship to student x height in inches y arm span in inches archie dad 72 72 ginelle mom 65 66 sarah sister 64 65 meleah sister 66 3/4 67 rachel sister 53 1/2 53 emily auntie 66 1/2 66 hannah myself 66 1/2 69 part two: representation of data with plots 1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph. part three: the line of best fit include your scatter plot and the answers to the following questions in your word processing document 1. 1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way. 2. write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. show all your work, including the points used to determine the slope and how the equation was determined. 3. what does the slope of the line represent within the context of your graph? what does the y-intercept represent? 5. use the line of best fit to you to describe the data correlation.

You can find the constant of proportionality by finding the ratio of
