Answer:
Step-by-step explanation:
We are required to find a unit vector in the direction of:
Unit Vector,
The Modulus of =
Therefore, the unit vector of the matrix is given as:
Pi is defined as the ratio of the circumference of any circle to its diameter. As all circles are similar and therefore proportional in dimensions, pi is therefore always the same for all circles and is constant
Answer:
Step-by-step explanation:
Before you can answer you have to solve the equation for y.
Y = 9/7 x+8/7
Parallel lines have the same slope so would also be 9/7
Perpendicular lines have opposite reciprocal slope so would be -7/9
