Answer:
2nd option
Step-by-step explanation:
given an exponential function in the form y = a
to find a and b use the coordinate points it passes through
using (0, 4 ) , then
4 = a [
= 1 ] , that is
a = 4 , so
y = 4
using (2, 100 )
100 = 4b² ( divide both sides by 4 )
25 = b² ( take the square root of both sides )
= b , that is
b = 5
then exponential function is
y = 4 .
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%.
