Answer: set 2 : O{(-6, -7), (-3, -3), (-2,-8), (-6,4)}
Step-by-step explanation: In order for a set of ordered pairs to be a function, then each input can correspond to only 1 output. In the context of your question, this means there cannot be two ordered pairs which have the same x value. The second set of ordered pairs does not represent a function because the input x = -6 corresponds to two different outputs, y = -7 and y = 4.
Answer:
32.5
................................
The area of a polygon is <span>A=perimeter×apothem÷2
</span>you know <span>A=500</span><span> and apothem = 10\
</span>
<span>500=<span><span>P×10/</span>2
</span></span>you should get that the perimeter is 100<span> from the algebra
</span>
<span>part 1 is 100, the perimeter is 100
</span>
The 100 * 7.95
