which of the following expressions is the definition of the derivative of f(x)=ln(x) at the point (5,ln5)
Doss [256]
The definition of the derivative is
\frac{f(x + h) - f(x)}{h}
as h goes to 0. So since the f is ln(x)

\frac{ln(x+h)-ln(x)}{h}

Since it is evaluated at 5 (the point 5, ln5), it is

\frac{ln(5+h)-ln(5)}{h}

Factor the polynomial.
mixer [17]

Answer:

Final answer is choice B. (5x-2y)^2

Step-by-step explanation:

We need to factor the given expression 25x^2-20xy+4y^2

25x^2-20xy+4y^2

=25x^2-10xy-10xy+4y^2

=5x(5x-2y)-2y(5x-2y)

=(5x-2y)(5x-2y)

=(5x-2y)^2

Hence final answer is choice B. (5x-2y)^2
