<em>The height of the rider from the ground after the Ferris wheel</em> equals <em>the starting point is 15 feet off the ground </em><em>plus </em><em>the radius of the Ferris wheel </em><em>plus </em><em>the opposite side of the triangle ΔABC </em>(See figure below).<em> </em>Hence our goal is to find this side. We have the angle 
, therefore the angle ∠BAC = 165° - 90° = 75°. So this side can be found using trigonometry:
Finally, the height is:
The solution to the graph is (-1,4). you should try desmos to help graph.
hope this helps and please rate as brainliest!! thanks!! :)

Step-by-step explanation:
The number of fish decreases by x% each year. x% can also be written as 0.01x.
If the total number of fish in a lake is A, after one year the number of fish will be:
After two years the number of fish will be:
So, the general formula for the number of fish after n years can be written as:
It is given that after 8 years, the number of fish is reduced to half. So we can write:
This means the value of x is 8.3%. So, the number of fish in a lake decreases by 8.3% each year
