First of all, the derivative of x is
Its norm is
Now we find
Therelore, we set
This means that the reparametrization of x in terms of arclength is
To write it clearly,
The two linear equations shown below are said to be dependent and consistent:
What happens if you use a graphical method?
A multiple regression equation to predict a student's score in College Algebra
a) According to this equation, what is the predicted value of the student's College Algebra score if their high school GPA was a 3.9, their high school Algebra II grade was a 2 and their placement test score was a 40? Round to 1 decimal place.
b) According to this equation, what does the student's placement test score need to be if their high school GPA was a 3.9, their high school Algebra II grade was a 2, and their predicted College Algebra score was a 67? Round to 1 decimal place.
