The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is
.
<h3>What is the value of a vector with respect to another vector?</h3>
First, we need to determine the value of the vector u by subtracting two vectors whose <em>initial</em> points are at the origin:

(1)
According to the statement, vector v is antiparallel to vector u and its magnitude is five times as the magnitude of vector v, which means that (1) must be multiplied by two scalars:
(2)
Please notice that antiparallelism is represented by the scalar - 1, whereas the dilation is represented by the scalar 5.

The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is
.
<h3>Remark</h3>
The statement presents typing mistakes, correct form is shown below:
<em>Vector u has initial points at (21, 12) and its terminal point at (19, - 8). Vector v has a direction opposite that of u, whose magnitud is five times the magnitud of v. Which is the correct form of vector v expressed as a linear combination of the unit vectors i and j?</em>

Answer:
should be left in the candy bar.
Step-by-step explanation:
Jenn and David shared a candy bar. Let's assume the bar was split into 10 parts, since 10 is the denominator of the fraction.
First, we need to add how much that the candy bar was eaten so we can subtract easier.
Jenn ate three tenths.
David ate four tenths.

So, seven tenths of the candy bar was eaten. We need to subtract that from a whole, because we need to know how much candy is left.

So, there are 3/10, or 0.3, of the candy bar left to share later.

Answer: 22.8 ft. squared
Step-by-step explanation:
5.7 x 8 = 45.6 ÷ 2 = 22.8
area of a triangle = base x height ÷ 2
Step-by-step explanation:
4(z+2)+4(z+3)
=4z+8+4z+12
=8z+20
by simplifying-
=2z+5
