Which expression has the greatest value |-21|, |14|, |30|, |-45|
tresset_1 [31]

Answer:

|-45|

Step-by-step explanation:

In mathematics, the absolute value of a real number is the numeric value of the  number, regardless the sign, either this is positive or negative.

The absolute value function can be definied as:

  • |a|=a si a ≥0
  • |a|=-a si a <0

Using this definition, we have:

|-21| = -(-21) = 21

|14| = 14

|30| = 30

|-45| = -(-45) = 45

Therefore, the expression |-45| has the greatest value.

Scorpion4ik [409]

Answer:

4,7,12,19,...

Step-by-step explanation:

<u><em>The question in English is:</em></u>

From the general term, calculate the first 4 terms.  

(Consider that you must assign values to the variable n)

we have

b_n=n^2+3

step 1

Calculate the first term

For n=1

b_1=(1)^2+3=4

step 2

Calculate the second term

For n=2

b_2=(2)^2+3=7

step 3

Calculate the third term

For n=3

b_3=(3)^2+3=12

step 4

Calculate the fourth term

For n=4

b_4=(4)^2+3=19

therefore

the first 4 terms are

4,7,12,19,...

Answer: No. The intervals defined by the margin or error overlap

Step-by-step explanation:
