  • Radius=3in

\\ \sf\longmapsto Circumference=2\pi r

\\ \sf\longmapsto Circumference=2(3)(π)=6\pi

Now

Check 1st option

\\ \sf\longmapsto \dfrac{9\pi}{3}.2=6\pi

Answer:

discrete

Step-by-step explanation:

This graph is discrete. A discrete graph has separate values, which are represented by multiple unconnected points. In continuous graphs, the values are all connected to each other. If this graph was continuous, then we would see a line rather than separate dots. The graph can also not be neither continuous nor discreet because it passes the vertical line test, meaning that it is a function.

Hope this helps :)

I will mark the brainiest answer
ki77a [65]

Answer:

17°

Step-by-step explanation:

∠AOC is a right angle, so it measures 90°

∠AOB and ∠BOC are in ∠AOC, so m∠AOB + m∠BOC = 90

m∠AOB = 73°

m∠BOC = x (shown in the diagram)

73 + x = 90

x = 17

4b + 5 = 1 + 5b <br><br> what is b?
Alla [95]

Answer: b = 4

Step-by-step explanation:

<u>Given</u>

4b + 5 = 1 + 5b

<u>Subtract 4b on both sides</u>

4b + 5 - 4b = 1 + 5b - 4b

5 = 1 + b

<u>Subtract 1 on both sides</u>

5 - 1 = 1 + b - 1

\boxed{b=4}

Hope this helps!! :)
