The coordinates of the images of the points are B'(x, y) = (0, 2), C'(x, y) = (3, 4), Z'(x, y) = (4, 3) and X'(x, y) = (4, 1), respectively.

In this problem we find four points set on Cartesian plane, each of which has to be transformed by using the following transformation rule about the origin:

(x', y') = (x · cos θ - y · sin θ, x · sin θ + y · cos θ)

Where:

(x, y) - Coordinates of the original point.

θ - Angle of rotation, in degrees.

If we know that B(x, y) = (- 2, 0), C(x, y) = (- 4, 3), Z(x, y) = (- 3, 4), X(x, y) = (- 1, 4) and θ = 90°, then the coordinates of the resulting point:

B'(x, y) = (- 2 · cos (- 90)° - 0 · sin (- 90°), - 2 · sin (- 90°) + 0 · cos (- 90°))

B'(x, y) = (0, 2)

C'(x, y) = (- 4 · cos (- 90°) - 3 · sin (- 90°), - 4 · sin (- 90°) + 3 · cos (- 90°))

C'(x, y) = (3, 4)

Z'(x, y) = (- 3 · cos (- 90°) - 4 · sin (- 90°), - 3 · sin (- 90°) + 4 · cos (- 90°))

Z'(x, y) = (4, 3)

X'(x, y) = (- 1 · cos (- 90°) - 4 · sin (- 90°), - 1 · sin (- 90°) + 4 · cos (- 90°))

X'(x, y) = (4, 1)

The perimeter of triangle 8 is 41 feet and 3 inches while the area is around 81.42 feet².

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In other meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

The given object is a triangle with sides of 13 ft 4 in,13 ft 4 in, and 14 ft 7 in.

A perimeter is the sum of all sides of the triangle.

There fore,

Perimeter = 13 ft 4 in + 13 ft 4 in + 4 ft 7 in

⇒ 41 feet 3 inches.

Now the area is given as 1/2 × base × height.

Here base = 14 ft 7 in and height = 11 ft 2 inch

Now,

1 inch = 1/12 ft so 7 inch = 7/12 feet and 2 inches = 2/12 feet.

So,

Area = 1/2 × (14 + 7/12) × (11 + 2/12)

Area = 81.42 feet²

Hence "The perimeter of triangle 8 is 41 feet and 3 inches while the area is around 81.42 feet²".

The measure of ∠B round to the nearest whole number is 76°.

Cosine is the trigonometric function that is equal to the ratio of the side adjacent to the acute angle in a right angled triangle.

Mathematically,

           Cos = Base/Hypotenuse

Now given that, a triangle ABC,

AB = 21

BC = 7

∠C = 90°

Thus, we have

hypotenuse = AB

Base = BC

Perpendicular = AC

So, for angle B

CosB = Base/Hypotenuse

⇒ CosB = BC/AB

Put the values we get,

⇒ CosB = 7/21

or,

CosB = Cos(75.53°)

⇒ B = 75.53°

Now the nearest whole number to 75.53° is 76°

Thus, we get

B = 76°

Thus, the measure of ∠B round to the nearest whole number is 76°.

Now, substitute the value of y as 8 + x in equation (2)

x + 8 + x = 32

Answer:

hope u will be clear from the given definition

The given expression can be written in its simplest form by using the rule of negative exponent.

As the negative exponent is applied to the second term, which also has a power, we will first multiply the powers. As we know that (x^n)^m=x^nm, hence,

(x^2/3)^-1=x^2/3*-1=x^-2/3

Now the expression will become 5x^-2/3

Now solving the second term for the negative exponent, the rule of negative exponent states that when a base term has a negative exponent, the negative sign can be solved by inversing the base term. We know that x^-a=1/x^a, therefore

5x^-2/3=5/x^2/3

The simplest form of the expression is 5(x²/₃)⁻¹=5/x^2/3

Answer:

[tex]f(x)=-x^2 + 11x - 24[/tex]

Step-by-step explanation:

Well for this problem, you want to start off by writing it in factored form.

In factored form, you can represent a quadratic as: [tex]f(x)=a(x-b)(x-c)[/tex], where x=b, and x=c are zeroes of the function, since plugging them into the function makes one of the factors zero, and multiplying zero by the other factors will just give you zero.

The "a" in front of the two factors generally defines the stretch/compression of the function.

So let's start by plugging in the zeroes into the function, and then we can solve for "a" later: [tex]f(x) = a(x-3)(x-8)[/tex]

Now let's use one point on the graph, which is not a root/zero to solve for "a". It's important to not use a zero/root since if we use that point the entire thing will be zero regardless of the value of "a"

Luckily we have one point provided that is not a zero and is: (4, 4)

So let's plug it in: [tex]4=a(4-3)(4-8)\\4=a(1)(-4)\\4=-4a\\a=-1[/tex]

So now let's plug this into the factored form to get: [tex]f(x)=-(x-3)(x-8)[/tex]

using foil to multiply these two factors you get: -[x^2 -8x - 3x + 24]

Now combine like terms

-[x^2 - 11x + 24]

distribute the negative sign

-x^2 + 11x - 24

What is a round-off of the digit?

In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.

For eg: 13.58 ~ 13.6

Solving the given equation:  log 4 + 2 log x = 6

We are given a logarithmic expression: log 4 + 2 log x = 6  

We know that e^(log b) = b

a log b = (log b)^a

log a + log b = log (ab)

Using exponential on both sides, we have

e^(log 4 + 2 log x) = e^6

e^(log 4 + log x² ) = 403.428

e^(log 4x² ) = 403.428

4x² = 403.428

x² = 403.428 / 4

x² = 100.857

x = 10.0427

Taking into account definition of perimeter and system of equations,  the length and width of the frame is 32 inches and 21 inches respectively.

The perimeter of a two-dimensional figure is the distance around the figure. That is, the perimeter of a flat geometric figure is called the length of its contour.

So, the perimeter is the measurement obtained as a result of the sum of the sides of a flat geometric figure. So to calculate the perimeter of a figure it is necessary to know two basic variables:

A rectangle is a flat geometric figure with four sides, of which two sides that are opposite parallel to each other have the same length and the remaining two have another length. The expression to calculate the perimeter of a rectangle is:

Perimeter= 2×(length + width)

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

In this case, a system of linear equations must be proposed taking into account that:

You know that:

So, the system of equations to be solved is

[tex]\left \{ {{2x(L+W)=106} \atop {L=2xW-10}} \right.[/tex]

From the several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the second equation in the first one you get:

2×(2×W - 10 + W)=106

Solving:

2×(3×W - 10)=106

2×3×W - 2×10=106

6×W - 20=106

6×W=106 + 20

6×W=126

W=126 ÷6

W= 21

Remembering that L= 2×W - 10, you get:

L= 2×21 - 10

Solving:

L= 32
