Answer:
a)
b)d(t)=500t
c)
Step-by-step explanation:
d = Horizontal distance
s = the distance between the plane and the radar station
The horizontal distance (d), the one mile altitude, and s form a right triangle.
So, use Pythagoras theorem


a) 
(b) Express d as a function of the time t (in hours) that the plane has flown.

d(t)=500t
(c) Use composition to express s as a function of t.

using b

Answer:

Answer:
1296
Step-by-step explanation:
Simple interest is
I = PRT where I is the interest P is the principle, r is the rate and t is the time
I = 1350 * .08 * 12
I = 1296
