Answer:
A
Step-by-step explanation:
Since the shape and vertex x coordinate of both graphs are the same, the only difference is the vertical displacement. Since the blue graph is 4 above the origin and the red graph is 1 above the origin, its graph is:
Hence, the correct answer is choice A. Hope this helps!
Answer:
124.7 in²
Step-by-step explanation:
A hexagon consists of six equilateral triangles, each of side a, and we can divide each of them into two right triangles.
So, we can calculate the area of one right triangle and multiply by 12.
The formula for the area of one triangle is
A = ½bh
Step 1. Calculate the length of the side a
Per the Pythagorean Theorem,
2.Calculate the area of a small triangle
The base of a small triangle is
b = ½a = ½ × 4√3 = 2√3
The area of one small triangle is
A = ½ bh = ½× 2√3 × 6 = 6√3 in²
3. Calculate the area of the hexagon
A = 12 × 6√3 = 72√3 = 124.7 in²
