What is the sum and classification of 2/5+square root of 88? a. 9. irrational b. 9. rational c. 13. irrational d. 13. rational

A. 9.78083151..., irrational.

Step-by-step explanation:

We are asked to find the sum and classification of .

Since 88 is not a perfect square, so we will find the value of square root of 88 using a calculator.

Upon adding both numbers we will get,

Since 2/5 is a rational number and is an irrational number as its decimal values are not terminating, therefore, the sum of both numbers will result in an irrational number.

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.
