Answer:
- <u>It is the first </u><em><u>graph</u></em><u>, whose description is: </u><em><u>The speed begins at 0, goes up at first, is steady for a while, and then goes down over time. </u></em>
Explanation:
Since the speed is on the vertical axis:
- the first stage shows that the car begins with speed 0 and increases its speed,
- then, the second stage shows that it travels a constant speed (constant speed is a steady line, i.e. paralell to the horizontal axis), and
- the third stage shows the reduction (decrease) of the speed.
In general, lines with positive slope are increasing functions, lines with negative slope are decreasing functions, and horizontal lines (slope = 0) are constant functions.

Answer:
The central angle is about 8.7°.
Step-by-step explanation:
The relation between angle and arc length is ...
s = rθ
where r is the radius, and θ is the central angle in radians.
600 = 3950·θ
θ = 600/3950 radians = (12/79)(180°/π)
θ ≈ 8.7°
