Answer: $858.25

Step-by-step explanation:

The sum of a geometric sequence is: $S_n=\dfrac{a_1(1-r^n)}{1-r}\ \text{where}\ a_1\ \text{is the first term and r is the ratio}$

In the given problem, $a_1=100$ and r = 1.02

$S_8=\dfrac{100(1-1.02^8)}{1-1.02}\\\\\\.\quad=\dfrac{100(1-1.17165)}{-0.02}\\\\\\.\quad=-5000(-0.17165)\\\\.\quad=858.25$

Week 1: $100
Week 2: $102
Week 3: $104.04
Week 4: $106.1208
Week 5: $108.243216
Week 6: $110.40808032
Week 7: $112.6162419264
Week 8: $114.868566764928

When the solutions are going to be complex, which methods can be used to solve quadratic equations?

yKpoI14uk [10]

You could complete the square to state the vertex.
You could use the quadratic equation to find the roots (which are complex).

Try an example that will require both.

y = x^2 + 2x + 5

Step One
Get the graph. That's included below.

Step Two
Provide the steps for completing the square.
Note: we should get (-1,4)

y= (x^2 +2x ) + 5
y = (x^2 +2x + 1) + 5 - 1
y = (x +1)^2 + 4

The vertex is at (-1,4)

Step Three
Find the roots. Use the quadratic equation. Note that the graph shows us that the equation never crosses or touches the x axis. The roots are complex.

$\text{x = }\dfrac{ -b \pm \sqrt{b^{2} - 4ac } }{2a}$

a = 1
b = 2
c = 5

$\text{x = }\dfrac{ -2 \pm \sqrt{2^{2} - 4*1*5 } }{2}$
$\text{x = }\dfrac{ -2 \pm \sqrt{4 - 20 } }{2}$
$\text{x = }\dfrac{ -2 \pm \sqrt{-16 } }{2}$
$\text{x = }\dfrac{ -2 \pm 4i }{2}$
x = -1 +/- 2i

x1 = -1 + 2i
x2 = -1 - 2i And we are done.

serious [3.7K]

Answer:

$1200.

Step-by-step explanation:

We have been given that Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website.

First of all we will find the number of subscribers for this month.

$\text{Total number of subscribers this month}=100+30-10$

$\text{Total number of subscribers this month}=130-10=120$

Now let us multiply number of total subscribers of this month by 10 to find the amount Kiersten will earn by her online business.

$\text{Kiersten's earnings this month from online business}=120*10$

$\text{Kiersten's earnings this month from online business}=1200$

Therefore, Kiersten will earn $1200 this month by her online business.

Use the initial term and the recursive formula to find an explicit formula for the sequence an. Write your answer in simplest fo

agasfer [191]

From the recursive rule

$a_n = a_{n-1}-13$

it follows that

$a_{n-1}=a_{n-2}-13 \implies a_n = a_{n-2} - 2\times13$

$a_{n-2}=a_{n-3}-13 \implies a_n = a_{n-3} - 3\times13$

and so on. Notice how the subscript on a on the right side and the coefficient multiplied by 13 add up to n (n - 2 + 2 = n; n - 3 + 3 = n; and so on). If we continue the pattern, we'll end up with

$a_n = a_1 + (n-1)\times13$
