Answer:
p=5i
Step-by-step explanation:
(p^(4)=-25p^(2))/p^(2)
p^(2)=-25
Square root both sides
p=5i
i is the square root of -1, so 5i is five times that much.
The square root of a negative number in not real. That is why it is i, and not a number.
 
        
             
        
        
        
The x is 176.54 cm.
i use pythagorean thearem
 
 
        
        
        
Given the equation  .
.
When x is maximum, we have
 . Hence
. Hence 
The maximum temperature is 
When x is minimum, we have
 . Hence
. Hence 
The minimum temperature is 
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Plugin x = 0 & y = -2 in the LHS of the equation. After substituting, if you get the RHS, then this point is the solution of the equation.
x - 2y = 0 - 2*(-2)
          = 0 + 4
          = 4  = RHS.
(0,-2) is solution of the equation.
