Answer:
The answer is that the vertex is: (1, 0)
Step-by-step explanation:
Use the "Completing the Square Method":
(x - h)^2 - k = 0, the vertex is (h, -k)
Complete the square:
x^2 + 2x + 1 = 0
x^2 + 2x = -1
(2/2)^2 = 1, add 1 to both sides of the equation.
x^2 + 2x + 1 = -1 + 1
(x + 1)^2 = 0
(x + 1)^2 - 0 = 0 (Just to put a placeholder in for he -k)
The vertex is (1, 0)
It is a number with a repeating decimal
Answer:
The measure of the apothem is 1.75 cm
Step-by-step explanation:
we know that
The area of a regular polygon is equal to
where
P is the perimeter of the regular polygon
a is the apothem of the regular polygon
Find the perimeter P
The perimeter of the regular octagon is equal to the length side of the octagon multiplied by 8 (the number of sides)
so
<em>Find the apothem</em>
we have
substitute in the formula
solve for a
