An acom fails from the branch of a tree to the ground 64 feet below. The distance, S, in feet, the corn is from the ground as it falls is represented by the function S(t) + -16t(squared) + 64 where
represents the number of seconds since the acorn began falling. How long does it take for the
acorn to reach the ground? 2 4 8 16

i think it is 70

step-by-step explanation:

3030 ur welcome

step-by-step explanation:

only 10/60 isn't equivalent

hope this : )

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.
