Answer:
C
Step-by-step explanation:
The graph can take any value of X
-3[ x^2 - 2x + 1] + 4
-3x^2 +6x -3 + 4
-3x^2 + 6x + 1 
x can take any value of real numbers and there would be a solution
Hence all real numbers is the domain.
 
        
             
        
        
        
Answer:
21. 123    22. 6.86 or 6/ 6/7  23. 90
Step-by-step explanation:
21. (6+4)² + (22+10÷2) 
      (10)² + (22 + 5) 
         100 + 27
            127
22. (11+42-5) ÷ (11-4)
          48 ÷ 7
         6.85 or 6 6/7
23. (17-3) × (14 - 6) -22
          14 × 8 - 22
          112 - 22
            90
 
        
             
        
        
        
Answer:
perimeter=25.12 ft
Area=50.24 ft^2
Step-by-step explanation:
Radius=4 feet
π=3.14
Perimeter=2 x π x Radius 
Perimeter=2 x 3.14 x 4
Perimeter=25.12 feet
Area=π x radius x radius 
Area=3.14 x 4 x 4
Area=50.24 ft^2
 
        
             
        
        
        
Angle ADC is an inscribed angle of arc AC. So the measure of arc AC would be 46. Angle CBA is a central angle, which means it is equal to the measure of arc AC. So the answer is 46. Hope this helps!
