Answer:
1974.6 feets
Step-by-step explanation:
The plane's altitude is : h + 100 feets
To obtain h, according to the attached picture ;
We can use trigonometry :
Tan θ = opposite / Adjacent
Opposite = h ; adjacent = 3000 feets
Tan 32° = h / 3000
h = 3000 * 0.6248693
h = 1874.6080
Plane's altitude :
h + 100 feets
(1874.6080 + 100) feets
= 1974.6 feets
Using the monthly payment formula, it is found that the amount he will have to pay each month is of $649.45.
<h3>What is the monthly payment formula?</h3>It is given by:
In which:
- P is the initial amount.
- r is the interest rate.
- n is the number of payments.
In this problem, considering that the down payment does not count for interest, the parameters are given as follows:
P = 130000, r = 0.0438, n = 30 x 12 = 360.
Then:
r/12 = 0.0438/12 = 0.00365 -> 1+r = 1.00365.
Then the monthly payment is given by:
A = 649.45.
