The maximum mileage per gallon for the compact car is determined by taking the first derivative of the given equation and equate to zero. The differentiated form is m's = -0.05 s + 2.45 = 0; s is equal to 49 seconds. substituting this s, m is equal to 30.025 miles/gallon.
        
             
        
        
        
Tan a = opposite side/adjacent side
tan 30 = 1050/ ?
1050/tan30=?
about 1818= ?
        
             
        
        
        
Answer: -8
Step-by-step explanation: So we after simplification we get
[(2/5) - (1/2) + (3/5)+ (7/2)] - [(3/5)/(1/4) - (1/5)]
After this I suppose it's just addition & subtraction, and can be easily done to get -8.
