Answer:
4x / (2x^2+1)
Step-by-step explanation:
g(x)=ln(2x^2+1)
Using u substitution
u= 2x^2 +1
du = 4x dx
g'(x) = d/du ( g(u) du)
We know that the derivative of ln(u) = 1/u since this is always positive
= 1/ u* du
Substituting x back into the equation
g'(x) = 1/(2x^2+1) * 4x
= 4x / (2x^2+1)

Answer:
Step-by-step explanation:
first lets find the total # of portions:
3+4+13=16+4=20
To make 4kg of this alloy you have to use:
nickel: (4/20)*3=12/20=6/10=0.6 kg
zinc: (4/20)*4=16/20=8/10=0.8 kg
copper: (4/20)*13=52/20=26/10=2.6 kg
