Assignment:Find the solution set of inequality (3000-6*(100+a))/sqrt((100+a)*16) >2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 3000 - 6 * ( 100 + a ) ) / sqrt ( ( 100 + a ) * 16 ) >2 (1)
From the definition field of √
( 100 + x ) * 16 ≥ 0 (2 )
From inequality(1):
a > -100
From inequality(2):
a ≥ -100
From inequalities (1) and (2)
a > -100 (3)
The final solution set is :
a > -100Your problem has not been solved here? Please take a look at the hot problems !
