A circle is a curve sketched out by a point moving in a plane. The equation that Mia will write is S = (360 × A)/(πR²).

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

Given the area of the sector of a circle is given by,

A = (πR²×S)/360°

Now, If Mia solved this equation for S, then the equation that she will write is,

S = (360 × A)/(πR²)

Hence, the equation that Mia will write is S = (360 × A)/(πR²).

Answer:

A

Step-by-step explanation:

To answer this, look at one specific point for example, A. It is at the point (3,6). In order for this point to get to where it was moved to, you must rotate it counterclockwise () 90 degrees. Do this by changing the initial point from (x,y) to (-y,x). This is located at (-6,3). Then you can see that it was translated 2 units up from there.

I hope this helped.

Rotate 90 degrees counterclockwise then translate 2 units up.

Option B is correct.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

In the figure ABCD, is transformed to figure A'B'C'D'.

It is Transformed from Quadrant 1 to quadrant 2

So, the point (x,y) is (-y,x).

It is then moved up by 2 units.

Now, the figure is rotated counterclockwise and translated up by 2 units.

The probability that Luisa gets 2 diamonds and 2 hearts (in any order) is:

P = 0.022

The probability of getting a particular type of card, is given by the quotient between the number of cards of that type and the total number of cards.

Here, let's assume that the 4 draws are:

diamond-diamond-heart-heart.

In that order.

First, the probability of drawing a diamond card is equal to:

p₁ = 13/52

Because there are 13 diamond cards and 52 cards in total.

Bt after that draw, there will be 12 diamond cards and 51 cards in total, so the probability of getting the second diamond card is:

p₂ = 12/51.

Now, there are 13 heart cards and 50 cards in the deck, so the probability of getting the first heart card is:

p₃ = 13/50

And the probability of getting the second one is:

p₄ = 12/49.

The joint probability will be the product of the 4 individual probabilities, but we also need to take in account the possible permutations, these are:

(using D for diamond and H for heart).

D - D - H - H

D - H - D - H

D - H - H - D

H - D - D - H

H - D - H - D

H - H - D - D

So there are 6 permutations, this means that the probability is:

P = 6*p₁*p₂*p₃*p₄ = 6*(13/52)*(12/51)*(13/50)*(12/49) = 0.022

Step-by-step explanation:

The parallelogram ABCD formed by vertices A(x, y) = (0, 0), B(x, y) = (3, 6) and C(x, y) = (11, 2) has a point D with the following coordinates: D(x, y) = (14, 8).

In this question we know only three vertices of the parallelogram. To determine the missing point we must understand the properties of parallelograms. Vectorially speaking, we can find the missing vertex by using the following property:

[tex]\overrightarrow{AB} = \overrightarrow {CD}[/tex]

[tex]\vec B - \vec A = \vec D - \vec C[/tex]

[tex]\vec D = \vec C + (\vec B - \vec A)[/tex]

D(x, y) = (11, 2) + [(3, 6) - (0, 0)]

D(x, y) = (11, 2) + (3, 6)

D(x, y) = (14, 8)

The parallelogram ABCD formed by vertices A(x, y) = (0, 0), B(x, y) = (3, 6) and C(x, y) = (11, 2) has a point D with the following coordinates: D(x, y) = (14, 8).

Since cosine is negative in the second and 3rd quadrant, the required angles are 120 and 240 degrees

Trigonometry identities are expressed as a function of cosine, sine and tangent.

Given the trigonometry expression shown

4cos2θ+9=−14cosθ

Equate to zero

4cos2θ+9 + 14cosθ = 0

According to trig identity

cos2θ = 2cos²θ - 1

Substitute to have:

4(2cos²θ - 1)+9 + 14cosθ = 0

Expand

8cos²θ - 4 + 9 + 14cosθ = 0

8cos²θ+ 14cosθ + 5 = 0

let P = cosθ to have;

8P² + 14P + 5 = 0

Factorize the result

8P² + 10P + 4P + 5 = 0

2P(4P+5)+1(4P+5)=0
(2P+1) = 0 and 4P+5 = 0
2P = -1 and P = -5/4

P = -1/2 and -5/4

Recall that P = cosθ

If P = -1/2

cosθ = -1/2

The volume of the pyramid.

The volume of a pyramid is found using the formula,

V = (1/3) Bh

where 'B' is the base area and 'h' is the height of the pyramid.

hight =2.4m

base=1.4+1.8

base=3.2m

V = (1/3) (3.2)(2.4)

V=2.56m^2

As we know the base of a pyramid is any polygon,

we can apply the area of polygons formulas to find 'B.
