Answer:

(About) 20043.46 after 14 years

Step-by-step explanation:

~ Let us apply a compound interest formula not through substituting values, but through a similar way of following this formula ~

1. First let us assign the values:

interest ⇒ 6.5 percent ( % ), principle number - start value ⇒ $ 8300, time ⇒  14 years

2. Now let us convert interest ⇒ decimal form: 0.065

3. Add 1 to this value 0.065 ⇒ 1 + 0.065 = 1.065

4. Now let us take 1.065 exponentially to the power of itself 14 times, or in other words to the power of time ( 14 years ): 1.065^ 14 = 2.414874185.......

5. Multiply this infinite number by the principle number P, or most commonly known as the start value: 2.414874185....... * 8300    ⇒    

(About) 20043.46 after 14 years

A phone company charges for service according to the formula: C(n) = 13 +0.07%, where n is the number of minutes
irina1246 [14]

Answer:

0.07

dollar per minute

Step-by-step explanation:

Given the charging formula :

C(n) = 13 +0.07n

n = number of minutes talked, and

C(n) = monthly charge, in dollars

The slope is the change in amount charged per change in the number of minutes talked.

Also, from The slope intercept equation :

y = mx + c

Comparing the equation :

0.07n = mx

m = 0.07

Since, The slope is the change in amount charged per change in the number of minutes talked.

Amount charged in dollars, talk time measured in minutes ;

Unit = dollar per minute

Because they have the same inclination so if we try to draw them on a diagram they will be parallel to each other.

Demi has 221 songs on her phone. The songs take up 884 megabytes of storage . Each song takes up same amount of space . How many
sveticcg [70]

Answer:

540 megabytes

Step-by-step explanation:

We will first need to find out how much space a<em> singular song</em> will take up. We will do this by <em>the storage taken up (884) by the number of songs she has:</em>

884 / 221 = 4 mb taken up per song

Then we want to find out how many megabytes <em>135 of these songs take up</em>, so we will multiply the <em>mb taken up per song (4) by the number of songs we want to find (135)</em>:

4 x 135 = <em>540 megabytes</em>

<em />

<em>Edit: made a mistake in my original answer, apologies!</em>

Luba_88 [7]

The graph approaches 0 as x approaches infinity.

Step-by-step explanation:

The behavior of the graph is presented by the function;

f(x)= 3x/4-x

Forming a table to see the behavior,

x          f(x)

1            1

2            3

3            9

4             infinity

5             -15

6              -9

7             -7

8             -6

This shows that as value of x approaches positive infinity, the value of f(x) approaches 0.
