It's the relation between the arc length of a circle, and the measure of angle. Before radians, we could only measure in degrees, and use pi to convert from arc length and circumference and angle measure. But, with the introduction of radians, it's much easier to map the relation. Hope it helps!
The statements which are correct are-
- The number of miles increases as time increases.
- The number of hours causes a change in the number of miles ridden.
- The variable h is the independent variable.
Step-by-step explanation
The above table displays the relationship between the time taken in hours ("h") by Mayon to cover the distance (miles "m").
It means that the distance is dependent on time in hours. Hence, the variable "m" is a dependent variable since it depends on time "h" for which bicycle is being ridden.
Similarly, the variable "h" is an independent variable.
As seen from the table, the value of "m" continuously increases for the value of "h" and thus the number of hours causes a change in the distance ridden.
