Answer:
$25,626.53
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 8.5% into a decimal:
8.5% ->
-> 0.085
Now lets plug in the values into the equation:


Lastly, subtract the total from the initial balance:

Michelle earned $25,626.53 in interest.
Polar and cartesian equation<h2>Initial explanation</h2>
Let's analyze the relation between r and x and y:
We have that between the indicated value of r (of the polar coordinates) and x and y (of the cartesian coordinates) there is a relation because they form a triangle. If r changes, then the value of x and y will change.
<h2>STEP 1: given equation</h2>
Using the given equation
r = 2 secØ
we have that

<h2>STEP 2: secØ equation</h2>
Observing the image of the initial explanation we have a right triangle, we know that the equation of
secØ for any right triangle is given by:

In this case,
hypotenuse = r
adjacent side = x
then,

<h2>STEP 3: comparison between given equation and secØ equation</h2>
Then, we have that:

This means that:

Then,
x = 2
The equation in cartesian coordinates is x=2.
Answer: x=2

Answer:
B, D
Step-by-step explanation:
The quadratic expands to ...
(2n -1)² = (2n)² +2(2n)(-1) +(-1)² = 4n² -4n +1
The coefficients can be factored out of the sum, so ...
∑(4n²) = 4∑n² for example
The sum of 60 ones is 60:

So, the sum can be written as ...

When u got a + in the middle, parenthesis are not needed
3x^2 - 2 + 2x^2 - 6x + 3...now we combine like terms
5x^2 - 6x + 1 <==
