Answer:
A
Step-by-step explanation:
Mother Russia is the mother land
F(2) = 8
if x = 2 then you plug in 2 for x making the equation 3(2) + 2 which equals 8
It will take her 4 days to read 1/3 of the book.
The answer is 4.
Circumference=2πr
=2*3.14*105
=659.4cm
To write the given quadratic equation to its vertex form, we first form a perfect square.
x² - 2x + 5 = 0
Transpose the constant to other side of the equation,
x² - 2x = -5
Complete the square in the left side of the equation,
x² - 2x + (-2/1(2))² = -5 + (-2/1(2))²
Performed the operation,
x² - 2x + 1 = -5 + 1
Factor the left side of the equation,
(x - 1)² = -4
Thus, the vertex form of the equation is,
<em> (x-1)² + 4 = 0</em>
