Answer:
That is has root -12 meaning if you replace x with -12 you get 0.
 
        
                    
             
        
        
        
R = 60
60^2 * pi = 3600 * pi
angle = 30°
3600pi / 30 = 120pi
the answer is 120 * pi
        
             
        
        
        
Answer:
   StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction
Step-by-step explanation:
Apparently you want to simplify ...
   
The applicable rules of exponents are ...
   (a^b)(a^c) = a^(b+c)
   1/a^b = a^-b
   (a^b)^c = a^(bc)
__
So the expression simplifies as ...
   
 
        
             
        
        
        
Answer:
Sqrt 80 = 8.94
Step-by-step explanation:
d = sqrt[(x-x)^2 + (y-y)^2]
d = sqrt [(6-2)^2 + (-9 - - 1)^2]
d = sqrt [(4)^2 + (-8)^2]
d = sqrt (16 + 64)
d = sqrt 80
d = 4 sqrt 5 = 8.94
