The area of the square= bxh 
 = 6x6= 36
The area of the rhombus is 4/5 the area of the square so 36x 4/5 = 28.8 
Area of rhombus = basexheight 
 28.8= 6x height 
Height = 28.8/6 
Height =4.8
        
             
        
        
        
Hello,
y = ax + b where a is the slope
We have A(-4 ; 2) and B(8 ; 5)

→ Slope : 3/2 
 
        
             
        
        
        
Given:
The power generated by an electrical circuit (in watts) as a function of its current x (in amperes) is modeled by

To find:
The current which will produce the maximum power.
Solution:
We have, 


Differentiate with respect to x.

 ...(i)
      ...(i)
To find the extreme point equate P'(x)=0.


Divide both sides by -30.

Differentiate (i) with respect to x.

 (Maximum)
 (Maximum)
It means, the given function is maximum at x=4.
Therefore, the current of 4 amperes will produce the maximum power.
