Finding higher-order derivatives in exercise, find the second derivative of the function.
f(x) = ln x/x^3 + x

d^2y/dx^2 = 2/x^2

Step-by-step explanation:

f(x) = y = In x/x^3 + x

Differentiating x/x^3 = [x^3(1) - x(3x^2)]/(x^3)^2 = (x^3 - 3x^3)/x^6 = -2x^3/x^6 = -2/x^3

Assuming u = x/x^3

In x/x^3 = In u

Differentiating In u = 1/u = x^3/x = x^2

Differentiating x = 1

dy/dx = x^2(-2/x^3) + 1 = -2/x +1

Differentiating -2/x = 2/x^2

Differentiating a constant (1) = 0

d^2y/dx^2 = 2/x^2 + 0 = 2/x^2

1; 35 is the ratio

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
