Answer: - 49
Step-by-step explanation:
f(x) = -2x - 1
g(x) =  - 1
 - 1
fg(x) = f ( - 1) , we just put in the value of g(x) , the next thing is to substitute
 - 1) , we just put in the value of g(x) , the next thing is to substitute  - 1 for the value of x in f(x) , that is
 - 1 for the value of x in f(x) , that is
fg(x) = -2( - 1) - 1
 - 1) - 1
fg(x) = -2 + 2 - 1
 + 2 - 1
fg(x) = -2 + 1
 + 1
Therefore : fg(-5) means we will substitute -5 for x in fg(x) , that is
fg(-5) = -2 ( + 1
 + 1
fg(-5) =  -2(25) + 1
fg(-5) = -50 + 1
fg(-5) = -49
 
        
             
        
        
        
Answer:
Denote AH as height of triangle ABC, with H lies on BC.
Applying sine theorem:
AH/AC = sin 60 
=> AH = AC x sin 60 = 47 x sqrt(3)/2 = 40.7
=> Area of triangle ABC is calculated by:
A = AH x BC x (1/2) = 40.7 x 30 x (1/2) = 610.5 = ~611
=> Option C is correct.
Hope this helps!
