Plz, answer this it is really easy.

v = 17.4 meters

Step-by-step explanation:

This is a triangle with height (red dotted line) given.

The area of a triangle is given by the formula:

Where

A is the area

b is the base length

h is the height

Given height = 12, and

area = 104.4

THe base is labeled as "v", so we find v by replacing into formula:

The base, v, is 17.4 meters

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.

5x+10 is the correct one

hope this
