We have to identify the rational function among the given functions.
Rational function is a function that is the ratio of two polynomials. It is rational because one polynomial is divided by the other polynomial, like a ratio.
1. Consider the first function
, since it is not a function that is the ratio of two polynomials. So, it is not a rational function.
2. Consider the second function
, since it is not a function that is the ratio of two polynomials. So, it is not a rational function.
3. Consider the third function
, since it is not a function that is the ratio of two polynomials. So, it is not a rational function.
4. Consider the fourth function
, since it is a function that is the ratio of two polynomials (x+2) and (5x). So, it is a rational function.
So, Option D is the correct answer.
In total, Kay took 5+14+2=21exams. she got 80%-90% on 14 of them. the probably is 14/21 which is 2/3. Therefore, the probability of Kay getting 80%-90% on her next exam is 2/3 or 66.6%
Answer:
Option A- 294.85
Step-by-step explanation:
Given : Andrea is buying a car for $21,450 she will finance $16,450 of it with a 5 year loan at 2.9% APR.
To find : The monthly auto payment.
Solution : From the table we get that monthly car loan payment per $1000 borrowed when interest rate is 2.9% on a 60 month loan is
Monthly car loan payment per $1000 borrowed is $17.924
Per $1000 the finance is
Monthly payment = Monthly car loan × Finance
Therefore, Option A is correct.
The Monthly payment is $294.85.
