18. The distance that a freely falling object falls varies directly as the square of the time it falls. If the object
falls 400 feet in 5 seconds, how far does it fall in 3
seconds?

240 feet

Step-by-step explanation:

Given that,

The object falls 400 feet in 5 seconds.

We need to find how far it fall in 3 seconds.

5 seconds = 400 feet

1 second = 80 feet

So,

In 3 seconds,

d = (80×3) feet

= 240 feet

So, it will fall 240 feet in 3 seconds.

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.
