Answer:
df/dx = e^x(1/x+ ln(x))
Step-by-step explanation:
f(x) = e^x * ln(x)
We can solve this by partial derivatives
df/dx = u dv + v du
let u = e^x and v = ln(x)
df/dx = e^x * 1/x + ln(x) * e^x
Factor out the e^x
df/dx = e^x(1/x+ ln(x))
2275/6 or 379.1667. You multiply the top (numerators) parts of the fractions and then the bottom (denominators). You then divide them.
The answer would be 3 weeks
0.8/1.2 = 0.6667
1 - 0.6667 = 0.3333
It is 33.33 % off
