Perform the indicated operation 5 1/6 - 2 2/3
goldenfox [79]

Answer:

2½

Step-by-step explanation:

First find the Least Common Denominator [LCD], which is 6, then convert 5⅙:

5⅙ → 4 7⁄6

5 \frac{1}{6}  - 2 \frac{2}{3}  = 4 \frac{7}{6}  -  2 \frac{4}{6}  = 2 \frac{3}{6}  = 2 \frac{1}{2}

You see, we regrouped 1 from 5⅙ to make sure that the top mixed number had a higher value than the bottom mixed number, so it is much easier to work with.

I am joyous to assist you anytime.

Vector u has initial points at (21,12) and it’s terminal point at (19,-8). Vector v has a direction opposite that of u. Who’s ma
8_murik_8 [283]

The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is \vec v = 10\,\hat{i} + 100\,\hat{j}.

<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:

\vec u = (19\,\hat{i} - 8\,\hat{j}) - (21\,\hat{i} + 12\,\hat{j})

\vec u = - 2\,\hat{i} - 20\,\hat{j}     (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:

\vec v = - 1 \,\cdot \, 5\cdot \vec u      (2)

Please notice that antiparallelism is represented by the scalar - 1, whereas the dilation is represented by the scalar 5.

\vec v = 10\,\hat{i} + 100\,\hat{j}

The correct form of vector v expressed as a <em>linear</em> combination of the <em>unit</em> vectors i and j is \vec v = 10\,\hat{i} + 100\,\hat{j}.

<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>
