Answer:
-3=b
Step-by-step explanation:
since its a -4 u seperate it from the vari by dividing 12 by the -4 ( since -4b inplies multiplcation. u always do inverse operation.)
(-3,0) is your answer

Answer:
c. 6.2i - 4.2j
Step-by-step explanation:
The vector projection when the angle θ not known can be calculated using the following property of the dot product:
Where the dot product of two vectors is given by:
And the magnitude of a vector is given by:
Using the previous definition, let's calculate the projection of w onto u:
First let's calculate the dot product between w and u:
Now let's find the magnitude of u:
So:
Therefore:
