Point B would have to lie on a circle of radius 8 centered at (5,-7). The answer is all ordered pairs (x,y) such that
(x - 5)2 + (y + 7)2 = 82 = 64

Question:
Fast travel to the three coordinate locations below in the geovisualization. What is the slope orientation (north facing, south facing) and mean height of the transition zone between desert (brown, no trees) and pinyon-juniper woodland (green, leafy trees) for these locations?
Location 1: 36.0180, -112.0132
Location 2: 36.0828, -112.1237
Location 3: 36.112, -112.2955
ANSWER CHOICES
A. South facing slopes with a treeline of roughly 1350 m
B. South facing slopes with a treeline of roughly 1200m
C. North facing slopes with a treeline of roughly 1350m
D. North facing slopes with a treeline of roughly 1200m
Explanation:
D. North facing slopes with a treeline of roughly 1200m Details. At the three locations, all the slopes are facing

Answer:
3.6 ft
Explanation:
Apparently, you're supposed to use the formula ...
A = (1/2)Pa
where A is the area, P is the perimeter, and 'a' is the apothem.
a = 2A/P = 2(43.26)/24 ≈ 3.605
The apothem is about 3.6 feet.
_____
<em>Comment on the problem</em>
For whatever reason, problems involving the use of the apothem are often inconsistently written. This one is no exception. The formula for the area in terms of side length is ...
A = 2(1 +√2)s²
The apothem is ...
a = s/(2·tan(22.5°))
For the given perimeter, A ≈ 43.46 square feet, and 'a' ≈ 3.621 ft.
