Answer:
The First choice
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the interval ------> [-1,∞)
-------> inequality B
The solution of the inequality B is the interval ------> (-∞,7]
The solution of the compound inequality is
[-1,∞) ∩ (-∞,7]=[-1,7]
therefore
the answer in the attached figure
Answer: -8

Answer:
253.89 pounds
Step-by-step explanation:
$1 = 0.74 pounds

Answer:
see explanation
Step-by-step explanation:
Given
2cosΘ - 
= 0 ( add to both sides )
2cosΘ = ( divide both sides by 2 )
cosΘ = 
Since cosΘ > 0 then Θ is in first and fourth quadrants, hence
Θ = 
( ) = 
OR
Θ = 2π - = 
solutions are Θ = ,
