If f(x) = [ex + ln(x)]-13, what is f '(x)? a.-13[ex + ln(x)]-12[ex + (1/x)] b.-13[ex + (1/x)]-12[ex + ln(x)] c -13[ex + ln(x)]-14[ex + (1/x)] d -13[ex + (1/x)]-14[ex + ln(x)] none of these

this is false ^.^ lol

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
