What is the sum of the geometric series in which a1 = 4, r = 3, and an = 324?
olganol [36]
\bf n^{th}\textit{ term of a geometric sequence}\\\\&#10;a_n=a_1\cdot r^{n-1}\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;r=\textit{common ratio}\\&#10;----------\\&#10;a_1=4\\&#10;r=3\\&#10;a_n=324&#10;\end{cases}&#10;\implies &#10;324=4(3)^{n-1}&#10;\\\\\\&#10;\cfrac{324}{4}=3^{n-1}\implies 81=3^{n-1}\implies 3^4=3^{n-1}\implies 4=n-1&#10;\\\\\\&#10;\boxed{5=n}\\\\

\bf -------------------------------\\\\&#10;\qquad \qquad \textit{sum of a finite geometric sequence}\\\\&#10;S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;r=\textit{common ratio}\\&#10;----------\\&#10;a_1=4\\&#10;r=3\\&#10;n=5&#10;\end{cases}&#10;\\\\\\&#10;S_5=4\left( \cfrac{1-3^5}{1-3} \right)\implies S_5=4\left(\cfrac{1-243}{-2}  \right)

and surely you know how much that is.

The initial value of a quantity Q (at year t = 0) is 112.8 and the quantity is decreasing by 23.4% per year. a) Write a formula
Svetach [21]

Answer:

a) Q(t) = 112.8*(0.766)^{t}

b) When t = 10, Q = 7.845.

Step-by-step explanation:

The value of a quantity after t years is given by the following formula:

Q(t) = Q_{0}(1 + r)^{t}

In which Q_{0} is the initial quantity and r is the rate that it changes. If it increases, r is positive. If it decreases, r is negative.

a) Write a formula for Q as a function of t.

The initial value of a quantity Q (at year t = 0) is 112.8.

This means that Q_{0} = 112.8.

The quantity is decreasing by 23.4% per year.

This means that r = -0.234

So

Q(t) = 112.8*(1 - 0.234)^{t}

Q(t) = 112.8*(0.766)^{t}

b) What is the value of Q when t = 10?

This is Q(10).

Q(t) = 112.8*(0.766)^{t}

Q(t) = 112.8*(0.766)^{10} = 7.845

When t = 10, Q = 7.845.
