Answer:
Let be the amount of parts the student answered correctly. Suppose that is a function between and the score of a student's project. As the student initially receives a fixed points for turning the project in and points for each correct part, the function is initially:
When the students receive points for each correct part, the coefficient of changes, as the amount of points received per correct answer increases. Thus:
.
GRAPHING CONS
1) hard to graph by hand. Often you need a graphics calculator or a computer software like maple or matlab. Or the graph has to be given.
2) hard to tell the exact solution, just by observing point of intersection. for example if x = 2.8675, the viewer would say x= 3.
3) sometimes not easy to decide the axis window of y and x axis. For example if the solution is very large like x = 100000 and your graph ends at x = 100, you cannot see the solution
SUBSTITUTION CONS
1) Becomes tedious if a system has too many equations or variables
ELIMINATION PROS/CONS
1) basically same as substitution
<u>Answer:</u>
The correct answer option is C. S = 54.6°.
<u>Step-by-step explanation:</u>
We are given a right angled triangle with two known sides, 
and 
.
We are to find the value of the angle 
.
For that, we will use sine.
S = 54.6°
