Lim <br> x → 1 <br> ln(x)/<br> sin(7πx)
mote1985 [20]
\displaystyle\lim_{x\to1}\frac{\ln x}{\sin7\pi x}

Note that both the numerator and denominator approach 0 as x\to1, so we can try using L'Hopital's rule.

\displaystyle\lim_{x\to1}\frac{\lnx }{\sin7\pi x}=\lim_{x\to1}\frac{\frac1x}{7\pi\cos7\pi x}=\lim_{x\to1}\frac1{7\pi x\cos7\pi x}

The denominator is nonzero at x=1, so the limit is equivalent to

\displaystyle\frac1{\lim\limits_{x\to1}7\pi x\cos7\pi x}=\frac1{7\pi\cos7\pi}=-\frac1{7\pi}

Brums [2.3K]

Answer:

  c.  $467.29

Step-by-step explanation:

The total of balances is $9360. The payment can be computed using the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^-n)

where A is the monthly payment, P is the principal (total balance), r is the annual rate, and n is the number of months.

Filling in your numbers, we have ...

  A = $9360(0.18/12)/(1 -(1 +0.18/12)^-24) ≈ $467.29

Frank's monthly credit card payment will be $467.29.
