6 = k/9 => k = 6 x 9 = 54 N
a = 54/2 = 27 meters per second per second
        
             
        
        
        
The answer is 2 bc I got it right on a quiz
        
             
        
        
        
Answer:
I will show all the steps to lead to the solution.
1) 10b = 5 (√c + 2)  <---- starting equation
2) divide by 5 => 2 b = √c + 2
3) subtract 2 => 2b - 2 = √c
4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.
Now these are two equivalent forms:
1) extract 2 from the parentheses: c = 4 (b -1)^2
2) expand the parentheses: c = 4b^2 - 8b + 4)

Answer:
the inverse of the quadratic function  is
  is 
Step-by-step explanation:
We need to find inverse of the quadratic function  
 
Let 

Replace x and y

Now, we will solve for y
Adding 3 on both sides


Taking square root on both sides

Now replace y with 

So, the inverse of the quadratic function  is
  is
