Robin fills a bathtub and then drains it. Use the following information to draw a detailed graph of the water level in the bathtub over time.
The water level starts at 0 cm.
After Robin turns on the taps, the water level rises at a rate of 0.5 cm/s for 10 s.
Robin turns off the tap at the 20 s mark.
The water level is constant for another 10 s. Then Robin pulls the plug, and the water level drops at a rate of 0.25 cm/s until the tub is empty.

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.
