Answer: $5,828.28
<u>Step-by-step explanation:</u>
Use the Compound Interest formula: where
- A is the accrued amount (balance)
- P is the principal (initial amount invested)
- r is the interest rate (in decimal form)
- n is the number of times compounded each year
- t is the time of the investment (in years)
Given: P = 4,900
r = 3.5% (0.035)
n = 2
t = 5
Check the picture.
Let the given points represent the following:
F : Charlie's feet
E: Charlie's eyes
P: location of the plane
G: the foot of the perpendicular drawn from P to the ground
A: a point on PG, such that |GA|=|FE|=5.2 feet.
Clearly EAP is a right triangle, with m(AEP)=32°, side PA=1,700-5.2=1694.8 feet.
<span>the ground distance from Charlie to the plane is |FG|=|EA|
from right angle trigonometry, we know that:
