Answer:
6. [tex]\pi = \frac{C}{2r}[/tex]
7. Translation
Step-by-step explanation:
6: To solve for π means to isolate it on one side.
Step 1: Divide both sides by 2r.
- [tex]\frac{C}{2r} = \frac{2\pi r}{2r}[/tex]
- [tex]\pi = \frac{C}{2r}[/tex]
Therefore, π = circumference over twice the radius, or circumference over diameter.
7: #7 is a translation because each point is moving vertically 3 units and horizontally 1 unit (3 units up and 1 unit to the right). If it were a reflection, we'd be able to spot a line of reflection, but there isn't any here. Also, if it were a rotation, the triangle would change the way its angled, and it'd be in a different quadrant
Therefore, this is a translation.
