1anne is riding a horse which is tied to a pole with a 3.5 m piece of rope and her friend laura is riding a donkey which is 2 m from the same center point. calculate the distance travelled by each when they have rotated 50 times around the centre.

c=2pie r  anne c=3.5m x 3.14 x 2 = 26 m x50= 1300m

laura c=2 x 3.14 x 2 =12.56m x 50 = 628m

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.
