Distance of A from cliff = 1500·arctan(30°) ≅ 723.5 ft
distance of B from cliff = 723.5+1000√3 ≅ 2455.6 ft
tanθ = 2455.6/1500 = 1.637
θ = arctan(1.637) ≅ 58.6°
angle of depression = 90-θ ≅ 30°
Answer:
The error is the solution.
The solution is all real numbers, or infinite amount of solutions.
Step-by-step explanation:
Step 1: Write equation
-4(2n - 3) = 12 - 8n
Step 2: Solve for <em>n</em>
- <u>Distribute -4:</u> -8n + 12 = 12 - 8n
- <u>Subtract 12 on both sides:</u> -8n = -8n
- <u>Add 8n to both sides:</u> 0 = 0
Here we see that <em>n</em> can equal any number. If you plug in any number <em>n</em>, it will render the equation true. Therefore, our solution is n = infinite amount of solutions.
n = 0 is only slightly correct. 0 does work as the solution, but there are solutions as well.
