Vertical asymptotes happen at x=a if the function is undefined at x=a.
This is a rational functions, and rational functions are not defined when the denominator is zero, since you can't divide by zero.
In this case, the denominator is zero if
And thus the function has a vertical asymptote at x= -3/2
Answer:
The fraction of total interest owed is
The value of it to the nearest tenth is 73.1%
Step-by-step explanation:
Let us solve it using the rule of 78
∵ The loan = 12 month
∵ The numerator is after 6 month
- Substitute n by 1 in each bracket
∴ The numerator = {(1 + 11) + (1 + 10) + (1 + 9) + (1 + 8) + (1 + 7) + (1 + 6)}
∴ The numerator = {12 + 11 + 10 + 9 + 8 + 7}
∴ The numerator = {57}
∴ The numerator of the fraction is 57
∵ The denominator = {(n) + (n + 1) + (n + 2) + .......... + (n + 11)}
- substitute n by 1 in each bracket
∴ The denominator = {1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12}
∴ The denominator = {78}
∴ The denominator of the fraction is 78
The fraction of total interest owed is
Now find the value of the fraction
∵ The fraction =
∴ Its value = 0.7307692308 × 100%
∴ Its value = 73.07692308%
- Round it to the nearest tenth
∴ Its value = 73.1%
The value of it to the nearest tenth is 73.1%
