A tree casts a shadow of 48ft. A man who is 6ft. tall casts a shadow of 4 ft. How tall is the tree?

72ft

Step-by-step explanation:

so you would divide 6 and 4 and that is 1.5

then you would do 48ft x 1.5 which is 72ft

so the tree is 72ft tall

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.
