9/20÷1/5=9/20×5/1 in word form you multiply 9/20 by its reciprocal.
first you want to simplify and change 9/20 to 9/4 and change 5/1 to 1/1 and then multiply to get 9/4
Using the power rule for differentiation, the first derivative of

is

and the second derivative is

which makes E the correct choice.
