Given:
The directed line segment from (-2, -5) to (7, 10).
A point partitions the segment into a ratio of 2 to 1.
To find:
The coordinates of that point.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of that point are
The point divides the line segment from (-2, -5) to (7, 10) in 2:1.
Using section formula, we get
Therefore, the coordinates of the partition point are (4,5).
Answer:
Step-by-step explanation:
If we simplify that fraction, we get
Keep that in mind.
If y, a ,b are zeroes of the cubic polynomial, then that means
make up the polynomial.
Notice that leading xoeffeicent will be 1, so the roots will multiply to
so
which gives us
Proof:
Consider the function
The roots are 2, 3, 5.
D is -30 so we get
Using the value,
If we use the orginal equation, we get
