According to the Rational Root Theorem, which number is a potential root of f(x) = 9x8 + 9x6 – 12x + 7?
2 answers:
Answer:
Seven-thirds
Step-by-step explanation:
The give equation is .
The leading coefficient is 9
The constant term is 7
According to the rational root theorem, the ratio of factors the constant terms to that of the coefficient of the leading term are all possible rational roots of the given polynomial.
Base on this theorem, or seven thirds is a potential root because the numeration is a factor of 7 and the denominator is a factor of 9.

Answer:
Interest rate is 1.4% and APR is 16.8%.
Step-by-step explanation:
Given,
The original cost of the car = $ 6,498,
Down payment = $ 798,
So, the present value of loan, P.V. = original cost - down payment
= $ 6,498 - $ 798 = $ 5700,
Now, the monthly payment, P = $ 162.51,
Number of months, n = 48,
Let r be the monthly interest rate,
Since, monthly payment formula of a loan,
By graphing calculator,
Hence, interest rate = 1.4%,
And, APR = 12 × 1.4% = 16.8%.
