Find the sum of the geometric series 9000-900 +...+ 0.009

bagirrra123 [75]

Based on the calculations, the sum of this geometric series is equal to 9,990.

<h3>The standard form of a geometric series.</h3>

Mathematically, the standard form of a geometric series can be represented by the following expression:

$\sum^{n-1}_{k=0}a_1(r)^k$

Where:

a₁ is the first term of a geometric series.

r is the common ratio.

<h3>How to calculate the sum of a geometric series?</h3>

Also, the sum of a geometric series is given by this mathematical expression:

$S=\frac{a_1(1-r^n)}{1-r}$

<u>Given the following data:</u>

First term, a = 9000.

Common ratio, r = 900/9000 = 0.1

Substituting the given parameters into the formula, we have;

$S=\frac{9000(1-0.1^3)}{1-0.1}\\\\S=\frac{9000(1-0.001)}{1-0.1}$

S = 9000(0.999)/0.9

S = 8,991/0.9

S = 9,990.

The number of people in pinellas county has been increasing at a rate of 1.3% per year.in 2016,there were 960,730 people. If x r

Anarel [89]

Answer:

$f(x) = 960730(1.013)^{x}$

Step-by-step explanation:

The number of people in Pinellas country has been changing at a rate of 1.3% per year.

If in the year 2016, there were 960,730 people in the country and if x represents the number of years since 2016, then the function that models the number of people in the country after x years since 2016 is

$f(x) = 960730(1 + \frac{1.3}{100})^{x}$

⇒ $f(x) = 960730(1 + 0.013)^{x}$

⇒ $f(x) = 960730(1.013)^{x}$ (Answer)
