Question

PLEASEEE ANSWER FAST THIS IS TIMED Bernadette throws the javelin for her school’s track and field team. The graph below shows the height and horizontal distance traveled by the javelin for three of Bernadette’s practice throws.

Use the graph to determine the average rate of change over the interval (0,20) for Throw #3. To earn full credit, show your work using a method explained in the Orientation.

Answer 1

Explanation:

Average ROC is
`Change=(f(b)-f(a))/(b-a) \\` so we need to look at the points (0,20) at 0 our y is 6 and at 20 its 12 so we have (0,6) and (20,12) we now use our formula so we have Change=
`(12-6)/(20-0) =(6)/(20) =(3)/(10)` so our answer is 3/10
