majintel:
the coefficient of friction was 0.73?

0.73 = Fr/Fn
Fn = 9.81m/s^2 * 150kg = 1471.5Newton (normal force)
Fr = 0.73 * 1471.5N = 1074.195N (friction force)

W = Fr * distance = 1074.195N * 12.3m = 13212.5985 Joule

((9/2)+(7/4)) / ((3/7)-(8/4))
((2*9/(2*2))+(7/4)) / ((4*3/(4*7))-(7*8/7*4))
( 18/4+7/4 )/ ( 12/28 - 56/28 )
(25/4) / ( -44 / 28 )
(25/4) / ( -11 / 7 )
(25/4) * ( 7 / -11 )
(25*7) / (-4*11)

Mathx:
Funktion f(x) = Wurzel aus x

[input]diff( sqrt(x), x )[/input]

f'(x) = (1/2)/(sqrt(x)) =1 / ( 2* sqrt(x) )
f'(1)= 1 / ( 2 * sqrt(1) ) = 1 / 2

f(x) = sqrt(x) = x^(1/2)
somit:
f'(x) = (1/2) * x^(1/2 - 1) =
1/2 * x^(-1/2) =
(1/2) / x^(1/2) ) =
(1/2) / sqrt( x ) =
1/(2*sqrt(x))

nuffsaid:
ut 16210\5824 in simplest form

[input]factorize( 16210)[/input]
[input]factorize( 5824 )[/input]
[input]gcd( 16210, 5824 )[/input]

greatest common divisor = 2.
16210 / 2 = 8105
5824 / 2 = 2912

so: 8105 / 2912

[input]x/2-4 1/2= x/10+1/4[/input]
x/2-4 1/2= x/10+1/4 | -1/4
x/2-4 3/4 = x/10 | *10
(x/2-4 3/4 )*10 = x
10x/2 - 47 1/2 = x | +47 1/2
10x/2 = x + 47 1/2 | -x
5x - x = 47 1/2
4x = 47 1/2 | /4
x = 11 7/8
