Assignment:Find the solution set of inequality -46496.605-4172.325×n+n^2/3×(273.82+15.044×n)×(821.46+30.088×n)/(547.64+30.088×n)-0.4×n^2×(186.14+5.8×n)×(558.42+11.6×n)/(372.28+11.60×n) ≥0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
-46496.605 - 4172.325 × n + n ^ 2 / 3 × ( 273.82 + 15.044 × n ) × ( 821.46 + 30.088 × n ) / ( 547.64 + 30.088 × n ) - 0.4 × n ^ 2 × ( 186.14 + 5.8 × n ) × ( 558.42 + 11.6 × n ) / ( 372.28 + 11.60 × n ) ≥0 (1)
From the definition field of divisor
547.64 + 30.088 × x ≠ 0 (2 )
From the definition field of divisor
372.28 + 11.60 × x ≠ 0 (3 )
From inequality(1):
-38.109771 ≤ n ≤ -11.304407 或 n ≥ 40.052724
From inequality(2):
n < -18.201276 或 n > -18.201276
From inequality(3):
n < -32.093103 或 n > -32.093103
From inequalities (1) and (2)
-38.109771 ≤ n < -18.201276 或 -18.201276 < n ≤ -11.304407 或 n ≥ 40.052724 (4)
From inequalities (3) and (4)
-38.109771 ≤ n < -32.093103 或 -32.093103 < n < -18.201276 或 -18.201276 < n ≤ -11.304407 或 n ≥ 40.052724 (5)
The final solution set is :
-38.109771 ≤ n < -32.093103 或 -32.093103 < n < -18.201276 或 -18.201276 < n ≤ -11.304407 或 n ≥ 40.052724Your problem has not been solved here? Please take a look at the hot problems !
