The relation is not a function. In order for a relation to be a function, the x-inputs of all ordered pairs must not repeat, and if they do, they must have only one output. In this problem, however, (9,4) and (9,1) both have different outputs (y-values). Therefore, there is no function present.

\text{Find the perimeter of the track field}\\\\\text{We already have one of our outside value, 50. We can multiply}\\\text{this by 2}\\\\50\cdot2=100\\\\\text{Now we need to find the perimeter, better known as the circumference}\\\text{of the half circle}\\\\\text{Since there is two half circles, we can make one}\\\text{whole circle}\\\text{Use the equation:}\\\\C=\pi \cdot d\\\\\text{Plug in and solve:}\\\\C=\pi \cdot 30\\\\C=94.24778\\\\

\text{Add 100 and 94.24778}\\\\100+94.24778= 194.24778\\\\\text{Round to the nearest hundredths place:}\\\\\boxed{\text{194.25 m}}

Rotating a polygon in Quadrant II 270° clockwise is the same as what?
lora16 [44]
The answer to this question would be: <span>rotating it 90° counterclockwise. 

When you rotate up an object 360</span>°, it will revert into its original places. That mean, if you rotate it more than 180°, then rotating it to the opposite direction will be easier/closer than you do. In this case, you rotate the polygon 270° so it will equal to 360° - 270°= 90° of opposite direction, which means counterclockwise. The quadrant shouldn't have any meaning in this question.
