What details can you determine about the dive from the coordinates of the point (5, −8)?

(See explanation below for further details)

Step-by-step explanation:

A. What details can you determine about the dive from the coordinates of the point (5, -8)?

First component corresponds to time and second component to depth with respect to sea level. The diver is 8 feet below sea level at 5 seconds.

B. What is the average speed of the diver in the water? How can you tell from the graph?

The average speed of the diver (), measured in feet per second, can be calculated by the following expression:

Where:

, - Initial and final depth of diver, measured in feet.

, - Initial and final instant, measured in seconds.

There are three different average speeds: (i) Descent ( to ), (ii) Ascent ( to ), (iii) Descent + Ascent ( to )

(i) Descent ( to )

and

(ii) Ascent ( to )

and

(iii) Descent + Ascent ( to )

and

C. Which point on the graph shows the starting location of the diver?

The initial location is when , which corresponds to the intercept of the line on y-axis.
