Answer:
125%
Step-by-step explanation:
so you are increasing by $10, and $10 is 25% of $40, so the percent change is 125%
 
        
                    
             
        
        
        
     5x³ + 8x² - 7x - 6
1) 
x + 2 is a factor because when using synthetic division, the remainder is zero.
-2  |  5    8    -7    -6
     <u>|  ↓   -10    4     6 </u>
        5   -2    -3     0  ← remainder is zero
2) 
x + 2 is not a factor because when using synthetic division, the remainder is not zero.
-1  |  5    8    -7    -6
     <u>|  ↓  -5    -3     10 </u>
        5   3    -10    4  ← remainder is not zero
 
        
             
        
        
        
=4/3 * 3.14 * 4.8³
=12.56/3 *110.592
=1389.0355/3
=463.01183
ie, 463 cubic inches(approx.)
