Inverse relationships are of the form xy=k or if you prefer  y=k/x so to find the constant we can say:
18(0.25)=k=4.5
So you could say: IR=4.5 or I=4.5/R
        
             
        
        
        
Answer:
(a) discriminant is positive, 76
(b) the above tells you there are two real roots
Step-by-step explanation:
the discriminant is 'b² - 4ac'
3x² - 2x - 6 = 0  ∴ a = 3, b = -2, c = -6
(-2)² - 4(3)(-6) = 4 + 72
 
        
             
        
        
        
Answer:
I think it is 6/1
Step-by-step explanation:
You are wrong because 0.167 into a fraction is 167/1000 and that isn't one of the options but when I did it 1 1/2=3/2=1.5 and 1/4=0.25 so I did 1.5 divide by 0.25 and it gave me 6 so that why I think that my answer is correct and yours is not.
 
        
             
        
        
        
Answer:
Circumference, C = 81.68 units
Step-by-step explanation:
Given that,
The radius of the circle, r = 13 units
We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :


C = 81.68 units
So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
