Answer:
y = -0.005x² + 50
Step-by-step explanation:
The diameter is 200 feet, so the parabola has roots at (-100, 0) and (100, 0). The maximum height is 50, so the vertex of the parabola is at (0, 50).
Using vertex form of a parabola:
y = a (x − h)² + k
y = a (x − 0)² + 50
y = ax² + 50
Plugging in either root:
0 = a (100)² + 50
a = -0.005
y = -0.005x² + 50

Answer:
It would be 7.
Step-by-step explanation:
You have to count the cubes that you can see and then the cubes you assume would be hidden behind the others. You can see 6 cubes, and we assume there's one hidden behind them.
Hope this helps!
Answer:
Step-by-step explanation:
The formula for calculate the volume of a sphere is shown below:
Where V is the volume of the sphere and r is the radius of the sphere.
The problem says that the radius of the sphere is 8. Then, you only need to substitute this value into the formula shown above.
Therefore, you can calculate it as following:
