First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx
now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
1+2+2lnx
3+2lnx is the answer
Answer:
We need dimensions to answer this.
Answer:
answer is i
Step-by-step explanation:
Answer:
20
23 is between 20 and 30, but it's closer to 20. So 23 is rounded down to 20.
Answer:
9x over 2 plus 60 if that's an option
