$\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{-1}{ h},\stackrel{-4}{ k})\qquad \qquad radius=\stackrel{2}{ r} \\\\[-0.35em] ~\dotfill\\[2em] [x-(-1)]^2+[y-(-4)]^2=2^2\implies (x+1)^2+(y+4)^2=4$

Drag the choices into the boxes to explain how all real numbers have a decimal expansion. The decimal forms of some real numbers

zvonat [6]

Answer:

$\frac{3}{16}$

$4\frac{2}{11}$

$\sqrt{5}$

Step-by-step explanation:

$\sqrt{5}=2.2360679...\\\\\frac{3}{16}=0.1875\\\\4\frac{2}{11}= \frac{46}{11}=4.18181818...$

The decimal forms of some real numbers, like $\frac{3}{16}$ , terminate, while the decimal forms of other real numbers, like $4\frac{2}{11}$ , do not terminate, but have a repeating pattern. Still other real numbers, like $\sqrt{5}$ , have decimal forms that neither terminate nor repeat.
