A. Write rules that predict the annual average temperature x decades from now for three different rate-of-increase estimates: 0.05°F, 0.10°F, and 0.15°F
per decade. Draw sketches of the various models on the same coordinate
system indicating clearly the rules corresponding to each graph.

step-by-step explanation:

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.

1

step-by-step explanation:

it's the only multiple of both and the least
