I think you can use cosine rule if only the lines that form the <52 are equal.
 
        
             
        
        
        
Answer:
3,158
Step-by-step explanation:
The formula is :
h(x)=-49(x)-125
h(-67)=(-49)*(-67)-125
h(-67)=3283-125
h(-67)=3158

Determine the volume
The volume of a cylinder is calculated as thus:

Substitute values for r and h


<em>Hence, the volume of the cylinder is 18312.48mm³</em>
 
        
             
        
        
        
(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
 4x + 1 = 2x + 5
 4(3) + 1 = 2(3) + 5
 12 + 1 = 15 + 5
 13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
 4x - 2x = 5 - 1
 2x = 4
 x = 4/2
 x = 2
This shows that x = 2 makes the equation true.
