Answer:

x=2

Step-by-step explanation:

To find the axis of symmetry for a quadratic, you use the formula:

x=-2ba

Looking at the chart, we can see that b=-1 (the vertical shift) and a=1 (the slope. Plugging these values into the formula, we get:

x=-2(-1)(1)=2

Therefore, x=2 is the axis of symmetry.

The much simpler way of determining this, however, is simply looking at the graph and finding where the vertex is. It is given here that the vertex point is (2, -1) and the graph is mirrored horizontally so you can simply take the x-coordinate and that will be the axis of symmetry. If the parabola was mirrored vertically, the axis of symmetry would then be the y-coordinate of the vertex.

Answer:

x = 2

Step-by-step explanation:

The axis of symmetry is a vertical line passing through the vertex, with equation

x = c ( c is the x- coordinate of the vertex ) , then

x = 2 ← equation of axis of symmetry

a student found the volume of a rectangular pyramid with a base area of 92 square meters and a height of 54 Meters to be 4968 cu
Naya [18.7K]
It is not correct. 

The student found the volume by multiplying the base area with the height. He forgot to divide it by 3.

Formula to find the volume of the pyramid = 1/3 base area x height

volume = 1/3 x 92 x 54 = 1656 square meters
