Answer:
9 hours. 
Step-by-step explanation:
So, first, you have to determine what he makes per hour to make this as easy as possible. You need to first do 396 divided by 18, which gives you 22. He makes 22$ an hour. Next, now that you know what he makes, you can do 198 divided by 22, and that'll show how long he has to work to make that amount of money.

Answer:
Yes
Step-by-step explanation:
1 : The athlete's hands push the medicine ball forward. The medicine ball pushes the athlete's hands backward.
2: Friction 
3: The first pair of action-reaction force pairs is: foot A pushes ball B to the right; and ball B pushes foot A to the left. The second pair of action-reaction force pairs is: foot C pushes ball B to the left; and ball B pushes foot C to the right 
 
        
             
        
        
        
First,
We are dealing with parabola since the equation has a form of,

Here the vertex of an up - down facing parabola has a form of,

The parameters we have are,

Plug them in vertex formula,

Plug in the  into the equation,
 into the equation,

We now got a point parabola vertex with coordinates,

From here we emerge two rules:
- If  then vertex is max value then vertex is max value
- If  then vertex is min value then vertex is min value
So our vertex is minimum value since,

Hope this helps.
