Given vectors a=(1,2), b=(2,-1), find 4a-3b

riadik2000 [5.3K]

A=(1,2) and b=(2, - 1) . Find 4a - 3b

1st carry out the scalar multiplication 4a and -3b

4a =[4(1) , 4(2) ] = (4 , 8)

-3b = [-3(2) . -3(-1)] = (-6 , +3)

4a - 3b = [(4-6) , (8+3)] = (-2 , 11)

maw [93]

Answer:

Rule:

$h = (1 - y,x + 3)$

Step-by-step explanation:

<em>I will answer generally, since the coordinates of f, g and h are not given</em>

Given

Point: x, y

Translation Rule

1 : x + 3, y - 1

2: 90 degree counterclockwise

Required

Determine the new coordinates

<u>At the first translation of (x,y) by x + 3, y - 1</u>

The new point is: $(x + 3, y - 1)$

<u>At the second translation (90 degrees counterclockwise)</u>

When a point (x,y) is translated using this rule, it becomes (-y,x)

So, the new point is:

$h = (-(y - 1),x + 3)$

$h = (1 - y,x + 3)$

If the initial point of h is (2,3),

The new point is:

$h = (1 - 3, 2 + 3)$

$h = (- 2, 5)$
