A) can.
because the number (x) has been decreased by 23 and is now 44.
Hope this helps :)
The answer is approximately 11.18.
6 / (x+1) = 1/2
x +1 = 12
x = 11
Answer is d ....(11)

By the fundamental theorem of calculus,

Now the arc length over an arbitrary interval

is

But before we compute the integral, first we need to make sure the integrand exists over it.

is undefined if

, so we assume

and for convenience that

. Then
The main formula is E = sum Work,
or the work is W= FxAB=E
so AB= E/F = 126/ 14 = 9m
