Answer:
x + 4/3x^3
Step-by-step explanation:
y=1/2x^2-2/3x^-2
dy/dx=1/2(2x)-2/3(-2x^-3)
=x+4/3 x^-3
=x+4/3x^3
 
        
                    
             
        
        
        
Answer:
<u>24 pieces</u> of fruits are use to make 2 fruit salads.
Step-by-step explanation:
Given:
Ken uses 6 apples and 2 bananas to make a fruit salad. He put twice as many oranges as bananas in the salad.
Now, to find the number of pieces of fruit Ken will use to make 2 fruit salads.
So, pieces of fruits use to make a salad are:
Apples = 6.
Bananas = 2.
Oranges = twice of bananas = 2×2=4.
So, total pieces of fruits to make a salad = 
Now, total pieces of fruits to make 2 fruit salads:



Therefore, 24 pieces of fruits are use to make 2 fruit salads.

Step-by-step explanation:
each daughter has 2 sisters and 2 brothers but each son had 1 brother and 3 sisters
 
        
                    
             
        
        
        
-1/3+2z=-5/6
-2/6+2z=-5/6
Add 2/6 to both sides:
2z=-3/6
2z=-1/2
Divide both sides by 2
z=-1/4
Hope this helps :)
        
             
        
        
        
For this we almost have the following equation:
 
 We must match the equation to zero: 

 From here, we clear the value of t.
 We have then:
