Answer:
The approximate area of the regular pentagon is 423 sq.cm.
Step-by-step explanation:
Formula of area of regular pentagon =
P=Perimeter of pentagon
a=Apothem
Side of pentagon = 14.1 cm
Perimeter of pentagon =
Apothem=12 cm
Area of regular pentagon = 
Hence the approximate area of the regular pentagon is 423 sq.cm.
All angles would have a sum of 180 degrees, so 180-140 is 40. And if you divide 40 by 2, the two side angles will be 20 degrees.
Fill in the point values in the formula for the derivative.
____
<u>Example</u>
y = x^2 + 3x . . . . . we want y' at (x, y) = (1, 4)
y' = 2x +3 . . . . . . . take the derivative dy/dx of the function
Fill in the value x=1 ...
y' = 2·1 +3 = 5
The value of the derivative at (x, y) = (1, 4) is 5.
