Final answer:
The derivative of the given function is (12.9 * (ln(4.9) * 4.9ˣ) * x² - 12.9 * (4.9ˣ) * 2x) / x⁴.
Step-by-step explanation:
The given function is f(x) = 12.9 * (4.9ˣ) / x². To find the derivative of this function, we can use the quotient rule.
The quotient rule states that if we have a function u(x)/v(x), then the derivative of the function is (u'(x)v(x) - u(x)v'(x)) / v(x)².
For the given function, u(x) = 12.9 * (4.9ˣ) and v(x) = x². Taking the derivatives, we have u'(x) = 12.9 * (ln(4.9) * 4.9ˣ) and v'(x) = 2x.
Substituting these values into the quotient rule, we get f'(x) = (12.9 * (ln(4.9) * 4.9ˣ) * x² - 12.9 * (4.9ˣ) * 2x) / x⁴.
