Assignment:Find the solution set of inequality 0 <0.3-0.602÷600×12-12×10^(-4)×(x^3-18.75x^2+75x) <0.2 .
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities:
0 <0.3 - 0.602 ÷ 600 × 12 - 12 × 10 ^ ( -4 ) × ( x ^ 3 - 18.75 * x ^ 2 + 75 * x ) (1)
0.3 - 0.602 ÷ 600 × 12 - 12 × 10 ^ ( -4 ) × ( x ^ 3 - 18.75 * x ^ 2 + 75 * x ) <0.2 (2)
From inequality(1):
x < 14.772648
From inequality(2):
1.484931 < x < 3.616751 或 x > 13.648318
From inequalities (1) and (2)
1.484931 < x < 3.616751 或 13.648318 < x < 14.772648 (3)
The final solution set is :
1.484931 < x < 3.616751 或 13.648318 < x < 14.772648 Your problem has not been solved here? Please take a look at the hot problems !
