Your Aunt Matilda passes away and leaves you with the tidy sum of $50,000. You find a bank that will pay you 5.15 % per year com

Answer:

Deduction in the step-by-step explanation

Step-by-step explanation:

If a P0=50.000 deposit is compound every instant, the ammount in the account can be modeled as:

$P(t) = P_{0}*e^{it}$

If you pull out d dollars a year, the equation becomes:

$P(t) = P_{0}*e^{it}-d*t$

If we derive this equation in terms of t, we have

$P(t) = P_{0}*e^{it}-d*t\\dP/dt=d(P_{0}*e^{it})/dt-d(d*t)/dt\\dP/dt=i*P_{0}*e^{it}-d\\$

The first term can be transformed like this:

$i*P_{0}*e^{it} = i*P(t)$

So replacing in the differential equation, we have

$dP/dt=i*P_{0}*e^{it}-d\\dP/dt=i*P(t)-d$

Rearranging

$dP/dt-i*P(t)=-d$

If f:R→R is continuous at a point c∈ R and g:R→R is continuous at f(c)∈R, then the composition g(f(x)) :R→R is continuous at c.

natima [27]

Answer:

The assertion that g(f(x)) is continuous at c is true.

Step-by-step explanation:

$let\\a=\lim_{x\rightarrow c}f(x)$

$\because f(x)$ is continuous at c

$\\\\Similarly\\\\b=\lim_{x\rightarrow f(c)}g(x)$

$\because g(x)$ is continuous at $\ x=f(c)$

$\lim_{x\rightarrow c }g(f(x))=g(f(c))\\\\=g(a)$ which is defined as per given data thus g(f(x)) is continuous at x=c
