The transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.
The table is given as:
<u>Original point ---- Image</u>
A (-4,-1) (1,-4)
B (-7,-6) (6,-7)
C (-14, -6) (6,-14)
D (-11, -1) (1,-11)
From the table, we can see that;
The coordinates are swapped, and the new x-coordinate is negated.
This represents 90 degrees counterclockwise rotation across the origin.
The rule of this transformation is:
i.e.
Hence, the transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.

Asked:
- The bigger pizza between the two given pizza.
- The area of the two pizza.
Given:
- First Pizza - radius of 12 inches
- Second Pizza - diameter of 20 inches
<u>Operation(s):</u>
- Multiplication
<u>Number Sentence/Formula:</u>
- A¹ = (3.14) (12 in)²
- A² = 1/4 (3.14)(20 in)²
Solution:
- A¹ = πr²
- A¹ = (3.14) (12 in)²
- A¹ = (3.14) (144 in²)
- A¹ = 452.16 in²
- A² = ¼ πd²
- A² ¼ (3.14)(20 in)²
- A² = 3.14/4 (400 in²)
- A² = 3.14 x 100 in²
- A² = 314 in²
Answer
- The first pizza is larger than the second pizza.
- The areas of the two pizza are 452.16 square
- inches and 314 square inches, respectively.
