K.E=0.5mv^2
GPE=mgh
 The child has both K.E and GPE


g is taken as 9.81
 
        
        
        
Answer:
Improper fraction =871/20
Mixed fraction =43 11/20
Step-by-step explanation:
 
        
             
        
        
        
Then the answer is 17 minus 8 times the square root of 2, or 5.68629
        
             
        
        
        
It will increase by 5/9 of a degree.
If you convert the given equation into slope intercept form, you will have:
c = (5/9)f + 160/9
In this form, it is easier to see the slope. The line would be increase by a rate of 5/9.
