Step-by-step explanation:
The boat's travel from when it was first noticed until it stopped is 554.89 ft.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly.
From the given information we can draw a right-angle triangle.
14°52' = 14 + 0.86 = 14.86 degree
45°10' = 45 + 0.16 = 45.16 degree
In the right-angle triangle ACD
tan14.86 = 200/AC
AC = 753.772 ft
In the right-angle triangle DBC:
tan45.16 = 200/CB
CB = 198.886 ft
AB = AC - CB
AB = 753.772 ft - 198.886 ft
AB = 554.886 ≈ 554.89 ft
Thus, the boat's travel from when it was first noticed until it stopped is 554.89 ft.

Answer:
The amount of Soyabean = 608.82 pounds.
The amount of Oats = 900-608.82 = 291.18 pounds.
Step-by-step explanation:
Given that the Soybean Meal has 46% CP and Oats has 12% CP.
The total amount of ration is 900 lbs of 35% CP.
Let x pounds of Soyabean has been used, so,
the amount of Oats = 900-x lbs.
The CP amount in 900 lbs mixture will be equal to the sum of CP amounts in x lbs Soyabean and 900-x lbs Oats, i.e
35% of 900 = 46% of x + 12% of (900-x)
![\Rightarrow \frac{35}{100}\times 900=\frac{46}{100}\times x+\frac{12}{100}\times (900-x)](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B35%7D%7B100%7D%5Ctimes%20900%3D%5Cfrac%7B46%7D%7B100%7D%5Ctimes%20x%2B%5Cfrac%7B12%7D%7B100%7D%5Ctimes%20%28900-x%29)
![\Rightarrow 35\times 900 = 46x + 12\times 900 - 12 x](https://tex.z-dn.net/?f=%5CRightarrow%20%2035%5Ctimes%20900%20%3D%2046x%20%2B%2012%5Ctimes%20900%20-%2012%20x)
![\Rightarrow 34x= 900(35-12)](https://tex.z-dn.net/?f=%5CRightarrow%2034x%3D%20900%2835-12%29)
![\Rightarrow x = (900\times 23)/34](https://tex.z-dn.net/?f=%5CRightarrow%20x%20%3D%20%28900%5Ctimes%2023%29%2F34)
lbs.
So, the amount of Soyabean = 608.82 pounds.
The amount of Oats = 900-608.82 = 291.18 pounds.
