Question

scale factor
scaled copies always have a scale factor.
look at imanis and anhs work.
show or describe where in their work you can see that the scale factor is 2.
imani:
anh:
original robot new robot
height (cm) 5 10
width (cm) 3 6
eye distance (cm) 2 4
antenna (cm) 1.5 3

Explanation:

Step1: Check height values

The height of the original robot is 5 cm and of the new robot is 10 cm. $\frac{10}{5}=2$.

Step2: Check width values

The width of the original robot is 3 cm and of the new robot is 6 cm. $\frac{6}{3}=2$.

Step3: Check eye - distance values

The eye - distance of the original robot is 2 cm and of the new robot is 4 cm. $\frac{4}{2}=2$.

Step4: Check antenna values

The antenna length of the original robot is 1.5 cm and of the new robot is 3 cm. $\frac{3}{1.5}=2$.

Answer:

In Imani's work, for each dimension (height, width, eye - distance, antenna), the value of the new robot is 2 times the value of the original robot. For example, height: original is 5 cm and new is 10 cm ($5\times2 = 10$), width: original is 3 cm and new is 6 cm ($3\times2=6$), eye - distance: original is 2 cm and new is 4 cm ($2\times2 = 4$), antenna: original is 1.5 cm and new is 3 cm ($1.5\times2=3$). So we can see the scale factor is 2 from the multiplication by 2 shown for height and antenna and the ratio calculations for all dimensions.
