An object falls 16t2 feet in t seconds. you drop a rock from a bridge that is 75 feet above the water. in 2 seconds, how many feet will the rock fall?

Distance fell by rock in 2 seconds = 64 feet

Step-by-step explanation:

An object falls 16t² feet in t seconds.

Now we are dropping an object from 75 feet above the water.

We need to find how much distance it falls in 2 seconds.

We have

              Distance = 16t²

              Distance = 16 x 2² = 64 m

So the rock will fall 64 feet in 2 seconds.

 Distance fell by rock in 2 seconds = 64 feet            

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
