Question

Find all real numbers x that satisfy this equation: ((25)/(1+2e^(-0.5t))=3

Answer 1

i think you can determine it by the help of the domain of e^x then exclude the the rest by finding the zeros of the function you had put

Answer 2

what is your opinion,how can we begin it ?- when on the left side there is a fraction what we need to do in first step ?

Answer 3

sorry now i see that there not is x

Answer 4

Start by isolating \(e^{-0.5t}\) and then take the natural logarithm \(\ln\) of both sides.
