Answer:
The answer is -256.
Step-by-step explanation:
You have to substitute the value of b and c into the expression :

Let b = 8,
Let c = -4,



 
        
             
        
        
        
8 shoes. each pair has 8!
        
                    
             
        
        
        
1) cscΘ = - 2
=>
        1
      ------ = - 2
      sinΘ
=> sinΘ = - 0.5 => Θ is in the third and fourth quadrant 
=> Θ = 180° + 30° = 210°
and Θ = 360° + 30° = 330°
2) tan Θ = √3
=> Θ = 60° and Θ = 180° + 60° = 240°
        
             
        
        
        
Answer:
It is the second answer
Step-by-step explanation:
The standard form of an ellipse is 
x^2/a^2 + y^2/b^2  or x^2/b^2 + y^2/a^2 = 1
If the x is the main axis we use the first form.  If the y is the main axis we use the second form.  We will use the second form.
our a is 3 and our b is 4
x^2/3^2 + y^2/4^2
