8. Find the arc length of a central angle of 7pi/3 in a circle whose radius is 3inches

pashok25 [27]

$\textit{arc's length}\\\\ s = r\theta ~~ \begin{cases} r=radius\\ \theta =\stackrel{radians}{angle}\\[-0.5em] \hrulefill\\ \theta =\frac{7\pi }{3}\\ r=3 \end{cases}\implies s=(3)(\frac{7\pi }{3})\implies s=7\pi \implies s\approx 21.99~in$

What’s the slope plz answer

Afina-wow [57]

The slope is $-2$ .

(Please comment if you want explanation)

Ok, My answer is marked wrong and I don't know why. Ok, kindakait asked for the slope of the line in the graph.

To find the slope of the line is $\frac{∆y}{∆x} \\$ or so they call $\frac{rise}{run} \\$ .

We can clearly see that to be at (-2,1) from (-4,5). You have to rise by -4 units and run by 2 units. Therefor:

$m = \frac{rise}{run} \\ m = \frac{-4}{2} \\ m = -2$ .

If you are not satisfied yet. Let's try another points. (0,-3) and (1,-5) and this is obvious by just eyeballing it.

$m = \frac{rise}{run} \\ m = \frac{-2}{1} \\ m = -2$ .
