Answer is 10.5 miles
I used Pythagorean theory to solve for the unknown distance from the waterfall to lookout point.
a^2 + b^2 = c^2
2^2 + 4^2 = c^2
20 = c^2
Take square root of both sides
4.47 = c
Rounded to 4.5 miles
Add 4 miles and 2 miles and 4.5 miles
10.5 miles total

Answer:
D
Step-by-step explanation:
The nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = - 3 , then
= 8 - 3(n - 1) = 8 - 3n + 3 = - 3n + 11 → D
