There could be many answers depending on where the centre of rotation is.

Assuming the centre is (0,0) It is an anticlockwise rotation of 90 degrees
L' is (-4,2)  M' is (-3,3)  and N' (0,2)

The coordinates of L ', M' and N ': (-4,2); (-3.3); (0.2)

<h3>Further explanation </h3>

Transformation is a change in shape or change in location from a building to another build.

A build can be changed in shape or location using transformation

There are several forms of transformation, including translation, dilation, rotation or reflection.

Rotation is a change in the position of an object because it is rotated with certain angles and centers

Generally for rotations with angles of 90 and 180:

  •  center (a, b)

90 °: (x, y) → (-y + a + b, x -a + b)

180 °: (x, y) → (-x + 2a + b, -y + 2b)

  • center (0,0)

90 °: (x, y) → (-y, x)

180 °: (x, y) → (-x, -y)

K (1,3) L (2,4) M (3,3) N (2,0). After the kite is rotated, K 'has coordinates (-3,1)

If we look at coordinates K -> K ' meets the 90 ° rotation rule: (x, y) → (-y, x) with a center of 0.0

so the coordinates of another point

 L (2,4) ---> -4,2

M (3,3) ---> -3,3

N (2.0) ----> 0.2

The area of a rectangle is 4w - 10 square units.
podryga [215]

Area of rectangle = 2(2w - 5) is the factored form of given expression

Multiplying the length and width of a rectangle, we get the area of the rectangle

<em><u>Solution:</u></em>

Given that, area of rectangle is 4w - 10 square units

We have to factor the expression

From given,

Area of rectangle = 4w - 10

Take 2 as common factor

Area of rectangle = 2(2w - 5)

Thus the given expression is factored

<em><u>The area of rectangle is given as:</u></em>

Area\ of\ rectangle = length \times width

Area\ of\ rectangle = 2 \times (2w - 5)

Thus, multiplying the length and width of a rectangle, we get the area of the rectangle

When we multiply 2 with 2w - 5 we get the area of rectangle

From above we can say,

Length = 2 or 2w - 5

Width = 2w - 5 or 2

So when dimensions of rectangle are multiplied we get area of rectangle

The correct options for the linear combinations of the vectors are given by:

A, B, C, D, E and F.

<h3>What is a span between two vectors?</h3>

The span between two vectors is the set that contains all linear combinations between these two vectors.

Supposing we have two vectors u1 and u2, as is the case in this problem, the infinitely many linear combinations have the following format:

k1u1 + k2u2

In which k1 and k2 are real numbers.

With k1 = 4 and k2 = -7, we get that option A is correct.

For option B, the vector 0 will always be a part of the span, as it can be formed with constants 0, hence it is correct.

The dimension of the span is of 3, as the vectors have 3 elements, hence option C is correct.

The underlying vectors will always also be part of the span, as they can be formed with their constant 1 and the others at 0, hence options D and F are correct.

The size of the span of any vectors is of infinity, hence option E is correct while option G is not.

Determine the amplitude or period as requested. Period of a y = - 1/3 * sin x - 1/3 pi/3 1/3 d 2pi
zysi [14]

Answer:

Period = 2\pi

Step-by-step explanation:

Given

y = -\frac{1}{3} * \sin(x - \frac{1}{3})

Required

Determine the period

A sine function is represented as:

y =A \sin(Bx + C) + D

Where

Period = \frac{2\pi}{B}

By comparing:

y =A \sin(Bx + C) + D and y = -\frac{1}{3} * \sin(x - \frac{1}{3})

Bx = x

So:

B = 1

So, we have:

Period = \frac{2\pi}{B}

Period = \frac{2\pi}{1}

Period = 2\pi

Hence, the period of the function is 2\pi

Can you add a negative and positive fraction or do you have to subtract it?
KengaRu [80]

Answer:

Hi

Step-by-step explanation:

You have to subtract it because you add a negative and positive fraction together you can add a positive with a positive or vice versa but you can add n and p together so you have to subtract.

Hope it helps
