This is my answer. Good luck!
 
        
        
        
   From the graph we observe:  
If x = 0 then y = 1/2    (because  e⁰ = 1)
 
 
        
             
        
        
        

but anyway, the numerator will give the angles, and θ is just half of each

ok... that's a negative tiny angle, is in the 4th quadrant, if we stick to the range given, from 0 to 360, so we have to use the positive version of it, 360-4.025
so the angle is 355.975°
now, the 3rd quadrant has another angle whose sine is negative, so... if we move from the 180° line down by 4.025, we end up at 184.025°
and those are the only two angles, because, on the 2nd and 1st quadrants, the sine is positive, so it wouldn't have an angle there
 
        
             
        
        
        
Answer: 
$103.75 for 8 hours
Step-by-step explanation:
8hr * 60min = 480min (for the total trip)
480min / 30min = 16 (30 minute intervals in her trip)
If the first half hour is a $25 dollar charge then,
$25 * 1 + $5.25 * 15 = $103.75 (for 8 hours)
