The graph is continuous because there can be fractional values for time
        
             
        
        
        
<h2><u><em>36x squared - 16y squared </em></u></h2>
        
             
        
        
        
I'm pretty sure it should be 2h+3
        
             
        
        
        
Recall the angle sum identities:


Now,

Divide through numerator and denominator by  to get
 to get

Next, we use the fact that  lie in the first quadrant to determine that
 lie in the first quadrant to determine that


So we then have


Finally,

 
        
             
        
        
        
.74 is the answer rounded to nearest hundredth.
