I don’t get this one but the question was something about finding the equation.
Alina [70]

9514 1404 393

Answer:

  y = -(x -3)^2 +2

Step-by-step explanation:

The vertex form of the equation for a parabola is ...

  y = a(x -h)^2 +k

where the vertex is (h, k) and the value 'a' is a vertical scale factor.

The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.

Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...

  y = -(x -3)^2 +2

Answer:

V= 42.41

Step-by-step explanation:

V = \pi r^{2}\frac{h}{3}

where r is the radius = 3 and h is the height = 4.5

V= \pi × 3^{2} × \frac{4.5}{3}

V = 42.41
