Answer: Definition of Vertical Angles.
Answer:
5/4, 1.3, 1 8/25
Step-by-step explanation:
5/4=1.25
1 8/25=1.32
---------------
A) Vectors are usually given in the form (x , y), therefore the x-component of v is 1.
B) Similarly to point A), the y-component of w is 6
C) the magnitude of the vector v+w is given by:
√[(x₁ + x₂)² + (y₁ + y₂)²] = √[(1 + (-2))² + (-3 + 6)²] = √(1 + 9) =√10
D) Compute -2 · v = (-2·1 , -2·(-3)) = (-2 , 6) = w
Therefore options B) and D) are true.
Answer:
x-3 is cancelled and just one remains in numerator.
