R=-1/800(x^2-2400x)
use R'=0
R'=1/400x-300, 1/400x=300 => x=1200 critical point
take R(1200), we know its max bcuz of the orientation of R
The order of the numbers from the greatest to the least is
|-20| > |12.3| > |8| > |-6| > |-4| > |2 3/10|
<h3>Magnitude of numbers</h3>
From the question, we are to order the given numbers from the greatest to the least in magnitude
The given numbers are
|-20|, |-4|, |-6|, |8|, |2 3/10|, |12.3|
Since the modulo sign is included, the <u>negative signs</u> do not take effect.
Hence, the order of the numbers from the greatest to the least is
|-20| > |12.3| > |8| > |-6| > |-4| > |2 3/10|
