Y = 1
Using y = mx + c.
Compare to y = 1,    y = 0x + 1 ,
We can see that the slope m = 0 and the vertical intercept, c = 1.
For the line perpendicular to  y = 1
Condition for perpendicularity  m₁m₂ = -1
m₁ = 0,  m₂ = ?
0*m₂ = -1
m₂ = -1/0 = Negative Infinite or Infinite 
Slope of line perpendicular to y = 1, is  = Infinite. 
        
             
        
        
        
The product of p and 9 mean 9*p so 9p so the 3rd choice is right sure 
        
             
        
        
        
Answer:
A: (3^2)*2
B: (2^3)*3
C: 2*19
D: (3^2)*9
Step-by-step explanation:
We have:
A) 18= 3*3*2= (3^2)*2
B) 24=2*2*2*3=(2^3)*3
C) 38 = 2*19
D) 81 =3*3*9=(3^2)*9
 
        
             
        
        
        
Because AB=RS=8m, ArcRS=Arc AB=ArcAR+ArcRB=55+66=121
        
             
        
        
        
Answer:
I think It would be A but I'm not exactly sure
