Answer:


Step-by-step explanation:
Standard form of a sideways parabola: 
Given equation:

Add x to both sides:


--------------------------------------------------------------------------------------------
<u>Standard form of circle equation</u>

(where (a,b) is the center and r is the radius)
Given equation:

Group like terms:

Divide by 2:

Factor by completing the square for each variable:

Rearrange into standard form:

Therefore, the circle has a center at (4.5, 2.5) and a radius of √23
Let E=elevation range
Low elevation=1700≤E≤2500<span>
Mid elevation= 2500</span>≤E≤4000<span>
Sulbarine=4000</span>≤E≤6500<span>
Alpine=6500</span>≤E<span>≤14,410</span>
If 2 triangles are similar, the ratio of one side of the triangle to the corresponding side of the other is always same for all 3 sides.
We can make use of this rule to calculate the length of sides.
From the image,
3 / 15 = 6 / x
Simplify,
1 / 5 = 6 / x
Use cross method to solve this.
5 x 6 = 1 x x
X = 30
Therefore the length of x is 30ft., A.
