For which of the following situations would a linear function be a reasonable choice for a mathematical model?
-the success rate of field-goal kicking as a function of distance from the goal post
-the number of people who have heard something as a function of time after the first person is told
-stopping distance (in a car) as a function of speed

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
