PLS HELP A newspaper delivery person in a car is tossing folded newspapers from
the car window to driveways. The speed of the car is 30 feet per second,
and the driver does not slow down. The newspapers are tossed horizontally
from a height of 4 feet above the ground. The height of the papers as they
are thrown can be modeled by y = –16t2 +4, and the distance they travel to
the driveway is d = 30t.

The delivery person starts to throw the newspapers at an angle and the height
of the papers as they travel can now be modeled by y=-16t+ 12t+4.
How long does it take the papers to reach the ground now?

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.
