Answer:

Step-by-step explanation:

hello :

f(x) =-2x²+4x+1 Completing The Square : f(x) =2(x²+2x)+1

f(x) = -2((x²-2x+1)-1)+1

f(x) = -2((x-1)²-1)+1

f(x) =2(x-1)²+1 ... verex form when the vertex is (1,1)

the axis of symmetry is x=1

The area of the sector of a circle with a radius of 8 centimeters is 125.6 square centimeters. The estimated value of pi is 3.14

tangare [24]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta\pi r^2}{360}\qquad 
\begin{cases}
\theta=\textit{angle in degrees}\\
r=radius\\
----------\\
r=8\\
A=125.6
\end{cases}
\\\\\\
360A=\theta\pi r^2\implies \cfrac{360A}{\pi r^2}=\theta\implies \cfrac{360\cdot 125.6}{\pi 8^2}=\theta$
