How do I draw this out I am confused?

The bridge forms parabolic arch. The span of the arch is 60 m and its center is 10 m above either end.
(1) draw sketch of arch, include x and y acts where the vertex is at the origin.

Is 10 m the axis of symmetry? What does it mean by span of arch?

*draw x and y axes

just answer

To draw the given arch, you can follow these steps:

1. Start by drawing a horizontal line to represent the ground.
2. On this line, draw two vertical lines upward, each 10 meters long. These represent the starting points of the arch.
3. Now, draw a curved line connecting the tops of the two vertical lines. The shape should resemble a parabolic arch. Make sure the center of the arch is 10 meters above the ground.
4. Label the point where the two vertical lines meet as the origin (0,0), which is the vertex of the arch.
5. Draw the x-axis, which is a horizontal line passing through the origin (0,0) and extending on either side.
6. Draw the y-axis, which is a vertical line passing through the origin (0,0) and extending above and below the arch.

Now, let's address your questions:

1. Is 10 m the axis of symmetry?
No, the axis of symmetry is a vertical line that runs through the vertex of the arch. In this case, since the vertex is located at the origin (0,0), the axis of symmetry is the y-axis.

2. What does it mean by the span of the arch?
The span of the arch refers to the length of the horizontal distance between the two endpoints or supports of the arch. In this case, the span of the arch is 60 meters, which means that the distance between the two vertical lines representing the supports of the arch is 60 meters.
