Answer:

Hey Hey here you go!

according to the chart thing y is the plane and x is hours

Question A- so the plane(y) goes 600 miles x hours. it says 600 per hour so 600 miles an hour.

Question B- the dependant vriable is 6 from 600. why? because it was the main source for the eqauation and we used it to subract 300 from to get the next answer.

Question C- 600 miles x 600 miles is 1,200 miles. wich would be 1,200 miles for two hours. it said two and a HALF hour so half of 600 is 300 so add that to 1,200 + 300 is 1,500 miles in 2.5 hours (two and a half hours.)

For the answer to the question above,
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years.
V(0) = 3500
V(2) = 2000

n = 0
V(0) = a * b^0 = 3500
a = 3500

V(2) = a * b^2
2000 = 3500 * b^2
b = sqrt (2000/3500)
b ≈ 0.76

V(n) = 3500 * 0.76^n

We can check it for n = 1 which is close to 2500 in the graph:
V(1) = 3500 * (0.76)^1
V(1) = 2660

And in the graph we have V(3) ≈ 1500,
V(n) = 3500 * (0.76)^3 ≈ 1536

Now n = 9.5
V(9.5) = 3500 * (0.76)^(9.5)
V(9.5) ≈ 258</span>
