The value of x is 8.56 units

Step-by-step explanation:

First, you have to find the distance from 0-1 using trigonometric function, tanθ = opposite/adjacent :

θ = 38°

opposite = 0-1

adjacent = 18

tan 38 = oppo./18

oppo. = 18 tan 38

= 14.063 units (3d.p)

Next, we have to find the distance from 0-2 using same formula :

tan 17 = oppo./18

oppo. = 18 tan 17

= 5.503 units (3d.p)

Lastly, we have to substract in order to find the value of x :

x = 14.063 - 5.503

= 8.56 units (2d.p)

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.
