You multiply 4x4=16 and 8x16=128. The volume is 128.

Answer:
Step-by-step explanation:
I find it convenient to use a graphing calculator to graph the function.
The "start" is x=0, where the distance from the sprinkler head is 0 feet. The value of h(0) is 9.5, the height of the sprinkler head.
- The irrigation system is positioned <u> 9.5 </u> feet above the ground.
The graph shows the vertex of the curve is (5, 34.5), meaning that a height of 34.5 feet is reached 5 feet horizontally from the sprinkler.
- The spray reaches a <u> maximum </u> height of <u> 34.5 </u> feet at a horizontal distance of <u> 5 </u> feet away from the sprinkler head.
- The spray reaches all the way to the ground at about <u> 10.9 </u> feet away.
The graph shows the x-intercept at about 10.9. That is where the height of the spray is 0 feet above the ground.
Hello from MrBillDoesMath!
Answer: Choice C
Discussion:
The y-intercepts are the x values where y = 0. Substituting y = 0 in the equation gives
(x+2)^2 + (0-4)^2 = 13 =>
(x+2)^2 + 16 = 13 =>
Subtract 16 from both sides
(x+2)^2 = 13 - 16 = -3 (*)
The square of a real number is greater than or equal to 0. (Not true for complex numbers). The left side of (*) is therefore >= 0 but as also equals -3. This is not possible so there is no solution to the equation. Choice C.
Thank you,
