Arock is thrown from the top of a building which measures 48 foot high. the graph shows the height, y, of the rock from the ground after x seconds. on which interval is the rock's height always decreasing

Step-by-step explanation:

The rock's height is increasing in the interval from 0 seconds to 3 seconds.

At time 0 the rock starts moving upward from 52 foot until it reaches 180 foot height (time 3 seconds). Then the rock starts to descend, which means that the height starts to decrease.

2.5 < x < 5.5

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.
