C=1n is the answer because the cost of hotdogs equals the price times the number of hotdogs
        
                    
             
        
        
        
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting : 
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side 
        
                    
             
        
        
        
3/6 = 24/48
3/4 = 36/48
3/8 = 18/48
3/8, 3/6, 3/4
        
             
        
        
        
Answer:
The figure below shows 4 congruent circles, each tangent to 2 other circles and to 2 ... a side of the square is 24 inches, then what is the area, in square inches, of 1 circle? A. 9 B. 9π C. 36 D. 36π E. 144. ... D The length of one side of the square is equivalent to the diameter of two circles: 24 = 2d. d = 12. Next, find the radius:.
