If length of an is 2.20 units the length of lm is units. write your answer as a decimal number to two decimal places

1.10 units.

Step-by-step explanation:

One side of the polygon measures 2.2 units. It is reflected along the x-axis. Since reflection preserves the size and the shape of the polygon, this means that the size of the first image of the polygon will remain unchanged. Second transformation is the dilation done by the factor k = 0.5. Dilation changes the size of the shape according to the dilation factor. If the original length of AB is 2.2, then the length of LM will be calculated by multiplying the original length with the dilation factor. Therefore, LM = 2.2 * 0.5 = 1.10 (correct to 2 decimal places).

Therefore, the length of LM is 1.10 units!!!

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.
