Step-by-step explanation:
General form of sin function is
Where A is Amplitude
B is
C is Mid line
1) Given : A sine function has the following key features
Frequency =
Period is
Amplitude= 2
Mid line y= 2
Y intercept (0,2)
This function is NOT a reflection of its parent function of the x-axis
Solution : We put the value in the general form of sin function
A= 2 , , C=2
2) Given : A sine function has the following key features
Period = 4
Amplitude = 3
Mid line y = -1
Y intercept (0,-1)
Solution : We put the value in the general form of sin function
A= 3 , , C=-1
3) Given : A sine function has the following key features
Period =
Amplitude = 2
Mid line y = -12
Y intercept (0,-2)
Solution : We put the value in the general form of sin function
A= 2 , , C=-2
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%.
