f(x)= -0.5(x-5)^2+8
The 2 exponent following the parentheses indicates it is a quadratic equation, which means it will have a parabola shape. The negative sign in front of the -0.5 indicates the parabola will open down. The + 8 indicates a translation of 8 spaces upward.

Answer: 15 inches
Step-by-step explanation:
Since the box must be square, we find the Lowest common multiple of 3 and 5, which is 15
Answer:
32 inches
Step-by-step explanation:
With two side lengths of 40 inches, the perimeter is made up of a remaining 64 inches. Therefore each of the two width sides are 32 inches. 32+32+40+40=144 inches.
The formula in solving the volume of a cylinder is Volume = pi*r²*h.
In the problem, the diameter is 24 inches. Since the radius is half of the diameter, therefore r = 24/2, r =12 inches.
As stated in the problem, the height is half of the radius. Therefore, the h=12/2, h=6 inches.
Volume = pi*r²*h
Volume = 3.14 * 12²*6
Volume = 864pi inches² or 2,712.96 inches²
The answer is the letter "B".
