Answer: 120
Step-by-step explanation:
20 divided by 20 is 1.
We have to multiply this by 120.
120 x 1 = 120. It is the answer.
+3 to both sides and you get s = -7
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)
Add 1/4 by 1/6 and get 5/12 so then you have 7/12 with black hair.
