Steps:
The definition of "reciprocal" is simple. To find the reciprocal of any number, just calculate "1 ÷ (that number)." For a fraction, the reciprocal is just a different fraction, with the numbers "flipped" upside down (inverted). For instance, the reciprocal of 3/4 is 4/3
 
        
                    
             
        
        
        
Answer:
a) dy/dx = 4/(2y+1)^2.
(b) y = 4/9 x - 14/9
(c) d2y/dx2 = -64/243
Step-by-step explanation:
You have the following equation
   (1)
(a) You first derivative implicitly the equation (1) respect to x:
next, you solve the last result for dy/dx:
(2)
(b) The equation for the tangent line is given by:
    (3)
with yo = -2 and xo = -1
To find the slope m you use the result of the equation (2), because dy/dx evaluated in (-1,-2) is the slope at such point:
m = 
Hence, by replacing in the equation (3) you obtain:
hence, the equation for the tangent line is y = 4/9 x - 14/9
(c) To find d2y/dx2 you derivative the result obtain in the equation (2):
     (4)
the second derivative for the point (-1,-2) is obtained by replacing y=-2 and dy/dx=m=4/9 in the equation (4):
hence, d2y/dx2 evaluated in (-1,-2) is -64/243

Answer:

Step-by-step explanation:
This is the answer because:
1) 185 equals to  because 18% is equal to 0.18 which is
 because 18% is equal to 0.18 which is  
 
2)  to it's lowest terms is
  to it's lowest terms is 
3) It's lowest terms is   because 18/2 is 9 and 100/2 is 50
 because 18/2 is 9 and 100/2 is 50
4)   can't be simplified any further because 9 and 50 don't have any common factors
 can't be simplified any further because 9 and 50 don't have any common factors
Hope this helps! :D
