What is the derivative of y = x^(lnx)? Show your solution.
aleksley [76]
Hello,

ln(y)=ln(x^(ln(x))=ln(x)*ln(x)=(ln(x))²

(ln(y))'=2ln(x)*1/x
(1/y)*y'=2ln(x) / x
y'=(2 ln(x) * x^(ln(x)) )  /x

The area of a parallelogram is A=bh

A=10(18.5) \\ A=185

I am assuming you're asking for the entire parking lot, so you would have to multiply the above area by 916

185(916) = 169,460  ft^{2}

So the answer is (D)
