Answer:

Step-by-step explanation:
Magnitude is solved with the following equation: 
Therefore, just plug in your x and y-values and solve.



Because
cannot be simplified further, this is the magnitude of the vector.
Answer:
m = 2
Step-by-step explanation:
Given:
x = 4
y = 6m - 2
a = 8
b = 5
Required:
Value of m
SOLUTION:
x and y are segments of a chord divided when it intersects another chord that also has segments a and b.
According to the Intersecting chords theorem, 
Thus:

Solve for m





The value of m = 2

To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.
1st class - X = no of students
2nd class - X + 6 no of students
Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.
1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.
There are 28 students in the larger class.
