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
Add 15 to both sides
Y = -27 + 15
Y = -12
-8x-8 and if you're supposed to choose multiple answers then let me know
Answer:
D'(4,-4), E'(5,-1), F'(8,0)
Step-by-step explanation:
After plotting DEF on a graph, individually move each plot point to the slope -2/1.
If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)
Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .
[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []
27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m
<u><em>Length of Fence = L = 780m + 2.7m = 782.7m</em></u>
