Be
P = (21, 12)
Q = (19, -8).
The vector u will be given by
u = PQ = Q-P = (19, -8) - (21, 12) = (- 2, -20)
The magnitude of this vector is
u = ROOT ((2 ^ 2) + (20 ^ 2)) = 20.1
Therefore, the vector v as it is in the opposite sense to u will be given by
v = 0.4i + 4j.
Its magnitude is
v = Root((0.4^2)+(4^2))=4.02
Dividing both magnitudes it is verified that the magnitude of u is five times greater than that of v
20.1 / 4.02 = 5.
Finally, the correct answer is
v = 0.4i + 4j
3 meters. If you glue one rod that is equivalent to 1 meter and another that is equivalent to 2 meters, then you just add them together. 1+2=3
Answer:
x= -5
Step-by-step explanation:
when you add like terms to a different side you change the sign so instead of adding -7 to -12 it would be 7-12 which is -5
