Answer: 8.4 %
Step-by-step explanation:
Since, the monthly payment formula,
Where, PV is the present value of the loan,
r is the rate per period,
n is the number of periods,
Here, PV = $ 80,000
P = $ 600
n = 12 × 30 = 360
Let r be the annual rate ,
⇒
⇒
⇒
⇒
Thus, the annual rate of interest = 0.082 = 8.2 %

It is the only equation given with multiple exponents and terms
Answer: Option D: R = {3, 9, 12}
Step-by-step explanation:
The range of a function is the set of the possible outputs of a function:
if we have the function f(x) = y, the values of x are the domain, and the values of y are the range.
In the image, the set at the right is the output, so the set in the right is the range.
such that we have the pairs (-2,3) (2, 3) (3, 9) (4, 12)
So the range will be R = {3, 9, 12}
