A = P(1 + r)^t
A = 500(1 + .06)^4
A = $631.24
<h2>Answer</h2>
f(x) = 5(1.25)x + 4
<h2>Explanation</h2>
To solve this, we are going to use the standard exponential equation:
where
is the initial amount
is the growth rate in decimal form
is the time (in months for our case)
Since the hours of classic music remain constant, we just need to add them at the end. We know form our problem that Sue initially has 5 hours of pop, so 
; we also know that every month onward, the hours of pop music in her collection is 25% more than what she had the previous month, so 
. Now let's replace the values in our function:
Now we can add the hours of classical music to complete our function:
Answer:
The answer is "It would decrease, but not necessarily by 8%".
Step-by-step explanation:
They know that width of the confidence level is proportional to a confidence level. As just a result, reducing the confidence level decreases the width of a normal distribution, but not with the amount of variance in the confidence level. As just a result, when a person teaches a 90% standard deviation rather than a 98 percent normal distribution, the width of the duration narrows.
Answer:
x = 4
Step-by-step explanation:
2x = 4x - 8
<em>subtract 2x from both sides of the equation</em>
2x - 2x = 4x - 2x - 8
0 = 2x - 8
<em>add 8 to both sides of the equation</em>
0 + 8 = 2x - 8 + 8
8 = 2x
<em>divide both sides of the equation by 2</em>
8/2 = 2x/2
4 = x
To solve this problem you must apply the proccedure shown below:
1. The area of the rectangle is:
Where 
is the width and 
is the length.
2. Based on the data given, solve for the width and then substitute the values of the length and the values of the area. Therefore, you have:
The answer is the second option:
