Question 621093: Give the component form of the resultant vector in the following.
NOTE: Answer must be typed in using the following format -- including the parentheses: (#,#)
u=(9,2)
v=(-5,-2)
2u-3v=?

You can put this solution on YOUR website! Hi, there--
.
Calculate the components of the resultant vector of 2u-3v. These are pretty straightforward computations. Just make sure you add and subtract the horizontal and vertical components separately in each step.
.
STEP I: Find the components of 2u and 3v.
.
u=(9,2)
2u=(2*9,2*2)
2u=(18,4)
.
v=(-5,-2)
3v=(3*-5,3*-2)
3v=(-15,-6)
.
STEP II: Subtract.
.
2u-3v=(18-(-15),4-(-6))
2u-3v=(33,10)
.
Hope this helps!
.
Ms. Figgy!
