Answer:

talk to me i hope this helps! :)

Step-by-step explanation:

How To Find Arc Length You need to know the measurement of the central angle that created the arc (the angle of the two radii) to calculate arc length. The arc length is the fractional amount of the (outside border of something/distance around the outside of a circle) of the circle. The (outside border of something/distance around the outside of a circle) of any circle is found with 2 Ï r where r = the radius.

Answer:

How To Find Arc Length You need to know the measurement of the central angle that created the arc (the angle of the two radii) to calculate arc length. The arc length is the fractional amount of the circumference of the circle. The circumference of any circle is found with 2 π r where r = r a d i u s.

Line E passes through the points (2, 3) and (4, -3). What is the slope of a line perpendicular to line E?

lilavasa [31]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 2 &,& 3~) 
% (c,d)
&&(~ 4 &,& -3~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-3}{4-2}\implies \cfrac{-6}{2}\implies \cfrac{-3}{1}$

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus

$\bf \textit{perpendicular, negative-reciprocal slope for}\quad \cfrac{-3}{1}\\\\
negative\implies +\cfrac{3}{ 1}\qquad reciprocal\implies +\cfrac{ 1}{3}\implies \cfrac{1}{3}$
