Answer:
Step-by-step explanation:
Let n represent the number of friends who went to the movies with you.
Then ($12/ticket)n + $15 = $75. Solving for n, we get:
$75 - $15 $60
---------------- = ----------------- = 5 so a total of 5 friends went with you.
($12/ticket) ($12/ticket)
Answer:
<h2>
Principal is $6441.22 </h2>
Step-by-step explanation:
let us assume the investment is compounded over the given period
Given data
Final amount A= $20,000
Rate r= 12%= 0.12
Time t= 10 years
principal=?
The compound interest formula is

Substituting our given data we have

Dividing both side by 3.105 to find P

Principal is $6441.22
Answer: Choice C 
========================================================
Explanation:
The vertical asymptotes are the red dashed lines. They are x = -4 and x = 0. Think of them as electric fences that the graph cannot touch or cross. The curve can only get closer and closer.
The vertical asymptote is due to a division by zero error.
When x = 0, the denominator x(x+4) turns into 0 since
x(x+4) = 0(0+4) = 0*4 = 0
Similarly, when x = -4, the denominator is also zero
x(x+4) = -4(-4+4) = -4*0 = 0
So if x = -4 or x = 0, then we have a division by zero error and that's what produces the vertical asymptotes at those locations shown on the graph.
This is why the answer is choice C.
