Answer:

Remainder is 13

Step-by-step explanation:

You can apply the remainder theorem here. You just equate the divisor to 0, then substitute the x-value in the expression.

$x^3 + 4x^2 - 2x + 1 \\$ then, $x+2=0\\x=-2$

substitute:

$-2^3 + 4(-2)^2-2(-2) + 1 =13$

Therefore, the remainder is 13

Patty made a banner that has an area of 175 square inches. The length and width of the banner are whole numbers. The length is 7

Leviafan [203]

Answer:

Length = 35

w = 5

Step-by-step explanation:

l x w = area

7y x y = 175

7y^2 = 175

y^2 = 175/7

y^2=25

y=5

The length is 7y, so it's 5 times 7 or 35.

The width is just y, so it's 5.

2 rooms would be 62+42 which is 104

3 rooms would be 104+42 which is 146

4 rooms would be 146+42 which is 188

5 rooms would be 188+42 which is 230

6 rooms would be 230+42 which is 272

but these are the prices including the 20$

without the 20$ the prices would be

2 rooms is 84

3 rooms is 126

4 rooms is 168

5 rooms is 210

6 rooms is 252

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>
