0.48 miles
Step-by-step explanation:
Step 1
It is given that the grade(slope) is 4%. This means that for every 100 miles traveled, the elevation changes by 4 miles. 
Step 2
Hence for a distance of 12 miles , the elevation changes by 12*4/100 = 48/100 = 0.48 miles. [Using direct proportion]
 
        
             
        
        
        
-28+2r+3r+5 
simplified it is -23+5r
        
                    
             
        
        
        
Present value = 135000
Monthly interest, i = 0.06/12 = 0.005
Monthly payment, A= 869.81
Future value of loan after 16 years

      [compound interest formula]


Future value of payments after 16 years



Balance = future value of loan - future value of payments
=351736.652-279288.456
= $ 72448.20
Note: the exact monthly payment for a 25-year mortgage is



Repeating the previous calculation with this "exact" monthly payment gives
Balance = 72448.197, very close to one of the choices.
So we conclude that the exact value obtained above differs from the answer choices is due to the precision (or lack of it) of the provided data.
The closest choice is therefore <span>$72,449.19</span>

Answer:
(-1, 4)
Step-by-step explanation:
Use of the coordinate plane. 
The vertex of the parabola is 1 to the left and up 4. 
Think of the vertex as where the curve starts.
