Answer:
sin -115° = -0.91
Step-by-step explanation:
Point A is (cos 115°, sin 115°). Since cos 115° = -0.42 and sin 115° ≈ 0.91, it means that the coordinates at point A is (-0.42, 0.91).
As for point B which was revolved around -115°,
the coordinates will be similar to point A but you just have to change the negative.
B(cos -115°, sin -115°) = B(0.42, -0.91)
<u>The formula for the monthly payment</u>.....
, where P = the principal amount, r = the monthly interest rate and n = the total number of months.
Here annual interest rate is given as 4.5%
So, the monthly interest rate
Total number of months
Also given that, the principal amount is $225000
a. So, the monthly payment will be.....
Thus, the monthly payment will be approximately $1140
b. The <u>total amount paid</u> over the term of the loan will be:
c. As the principal amount was $225000 , so the amount of interest
So, the percentage of amount that is paid toward the principal
and the percentage of amount that is paid toward the interest
