Step-by-step explanation:
 
        
             
        
        
        
In Cartesian coordinates, the region (call it  ) is the set
) is the set

In the plane  , we have
, we have

which is a circle with radius  . Then we can better describe the solid by
. Then we can better describe the solid by

so that the volume is

While doable, it's easier to compute the volume in cylindrical coordinates.

Then we can describe  in cylindrical coordinates by
 in cylindrical coordinates by

so that the volume is

 
        
             
        
        
        
The ball will hit the ground when h(t)=0 so:
16t^2-96t=0
16t(t-6)=0, since t>0
t=6
So the ball with hit the ground after 6 seconds.
        
                    
             
        
        
        
Answer:
-9
Step-by-step explanation:
-2x + 3 = -x + 12
move -x over by adding
-x + 3 = 12
move the 3 over by subtracting
-x = 9
divide by - to get the x positive
x = -9
