Given:
The radius of the given diagram = 9 inches
The value of given angle = 120°
To find the length of the arc.
Formula:
The relation between arc (S), radius (r) and the angle () is:
=
Now,
Putting, we get,
Hence,
The length of the arc is inches.
The answer to this is 4) 4.0
L'hopital's rule
the limit of f(x)/g(x) as x approaches n is
take deritivive of top and bottom untill you get someting
this only applies if initiallly we get 0/0 or inifnity/infinity
(0^2cos(0))/(1-cos(0))=0/0
we can use it
take the deritivive of top and bottom
(2xcos(x)-x^2sin(x))/(sin(x))
gets 0/0
take derititve again of top and bottom
((2-x^2)cos(x)-4xsin(x))/(-cos(x))
2/1=
2
it approaches 2
It will be B because Problem A,C,D is wrong not Problem B
