Answer:
Horizontal distance = 1218.41 ft
Step-by-step explanation:
Given data:
Slope distance = 1223.88 ft
Zenith angle is  = 95°25'14" 
converting zenith angle into degree 
Zenith angle is  94.421°
 94.421°
Horizontal distance
putting all value to get horizontal distance value
Horizontal distance 
Horizontal distance = 1218.41 ft
 
        
             
        
        
        
The power increases by 21% per hour. 21% written as a decimal is 0.21.
Because it increases you would multiply the starting value by 1.21 times the number of hours (t).
 That needs to be less than or equal to 100,00
The equation would be:
C: 15,040(1.21)t ≤ 100,000
 
        
                    
             
        
        
        
If you're asking for extrema, like the previous posting
well

like the previous posting, since this rational is identical, just that the denominator is negative, the denominator yields no critical points
and the numerator, yields no critical points either, so the only check you can do is for the endpoints, of 0 and 4
f(0) = 0        <---- only maximum, and thus absolute maximum
f(4) ≈ - 0.19  <----  only minimum, and thus absolute minimum
