Step-by-step explanation:100% correct
Octagons have 8 sides. If each side is 5 feet then the perimeter is 40 feet. You add up the sides.
B

5,000
because the library has more than or = to 5000 books.
The path is in the shape of a parabola, the horizontal length is 24, so the middle point is at x=12, the symmetry line is x=12, the highest point (the vertex) is at (12,6)
the equation in vertex form is y=a(x-12)²+6
next, find a by using either one of the two points, the starting point (0,0) or the end point (0,24). obviously (0,0) is easier to calculate:
0=a(0-12)² +6
a=-1/24
so the quadratic equation is y=-
