[(1/(3+x))-(1/3)] / x<br> Limit 0
Effectus [21]
First find a common denominator and combine the fractions in the numerator:

\displaystyle\lim_{x\to0}\frac{\dfrac1{3+x}-\dfrac13}x=\lim_{x\to0}\frac{\dfrac3{3(3+x)}-\dfrac{3+x}{3(3+x)}}x=\lim_{x\to0}\frac{3-(3+x)}{3x(3+x)}

Now simplify and cancel out all the terms that you can:

\displaystyle\lim_{x\to0}\frac{3-3-x}{3x(3+x)}=-\frac13\lim_{x\to0}\frac1{3+x}

Since the remaining expression is continuous as a function of x, you can directly substitute to end up with

\displaystyle-\frac13\lim_{x\to0}\frac1{3+x}=-\frac13\times\frac1{3+0}=-\frac19

Natsumi opens a savings account that earns 0.08% interest on the last day of the month. Her initial deposit is $75 on the first
Nitella [24]

Because she doesn't receive any interest on the last month, but puts money in, we can write this equation:

18(75) + 17(0.08(75))

1350 + 1.36(75)

1350 + 102

She will have $1452 On the eighteenth month
