The width of a virus is 2.0 x 10 to the(-7)th meter. Write this number in standard decimal notation

2×10^(-7)=0.0000002m

You have 6 zeros in front of 2.

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.

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
