The dimensions of the image are twice the dimensions of the preimage,
which indicates that the transformation is a dilation.
- The transformation <em>T</em> is; <u>a dilation transformation with a scale factor of 2, D₂</u>
Reasons:
The transformation applied to ΔABC = T
The image of ΔABC following the transformation, T = ΔA'B'C'
The perimeter of ΔA'B'C' = Twice the perimeter of ΔABC
Therefore, we have;
A'B' + B'C' + A'C' = 2 × (AB + BC + AC)
Which gives
A'B' + B'C' + A'C' = 2·AB + 2·BC + 2·AC
By similar triangles, we have the ratio of corresponding sides as follows;
Which gives;
A'B' = 2·AB
Therefore;
- Triangle ΔA'B'C' is twice the dimension of triangle ΔABC, and <em>T</em> is <u>a dilation transformation with a scale factor of 2, D₂</u>

Answer:
Step-by-step explanation:
Let "x" represents the 16% of 43 minutes.
Once you analize the information given in the exercise, you can identify that 43 minutes is the 100%.
Then, with this data, you can set up the following proportion:
Now you must solve for "x". The steps are:
- Multiply both sides of the equation by "x"
- Multiply both sides by 43:
- Divide both sides by 100:
- Rounding to the tenths place:
