Answer:

≈ 38.64 units

Step-by-step explanation:

The length of arc s is calculated as

circumference of circle × fraction of circle

The central angle subtended by arc s is 360° - 114° = 246° then

arc s = 2πr × $\frac{246}{360}$

= 2π × 9 × $\frac{41}{60}$

= 18π × $\frac{41}{60}$

≈ 38.64 ( to 2 dec. places )

-5 < x - 4 greater than it equal 1

saul85 [17]

We have expression $-5 < x - 4 \geq 1$ that renders the system of inequalities,

$\begin{cases}-5 < x - 4 \\x - 4 \geq 1\end{cases}$

Which can be simplified to,

$\begin{cases}x > -1 \\x \geq 5\end{cases}$

So what we get is something greater than -1 and at the same time greater or equal to 5, so the solution is,

$x\in(\infty,-1)\cap(\infty, 5]=\boxed{(\infty,5]}$ .

Hope this helps.
