find the area of parallelogram .
I need to know how to solve this. can someone please explain it I'm trying to help my son out. this one is tricky it has a fraction.​

Answer:

A. 8

Step-by-step explanation:

BE = ½(CD) (midsegment theorem)

BE = 2x - 10

CD = 12

Plug in the values

2x - 10 = ½(12)

2x - 10 = 6

Add 10 to both sides

2x - 10 + 10 = 6 + 10 (addition property of equality)

2x = 16 (addition property of equality)

Divide both sides by 2

2x/2 = 16/2

x = 8 (division property of equality)

Step-by-step explanation:

x^2-9x=-2  move the -2 over and set to 0

x^2-9x+2=0  

This can not be factored, so use the quadratic formula.

x=9±√73 /2

Answer:

x = 9 + sqrt(73) / 2

x = 9 - sqrt(73) / 2

Step-by-step explanation:

Assuming you want to factor and find its roots:

[Put all the terms in the left hand size]

x^2-9x+2=0

[Use the quadratic formula; Not factorable and too tedious for completing the square]

x = -b +- sqrt(b^2-4ac) / 2a

x = 9 + sqrt(9^2 - 4(1)(2)) / 2(1)

x = 9 - sqrt(9^2 - 4(1)(2)) / 2(1)

x = 9 + sqrt(73) / 2

x = 9 - sqrt(73) / 2

Answer:

\(21.7 x 10^5\)

Step-by-step explanation:

(6.2 x 10²) x (3.5 x 10³)

First, multiply the coefficients: 6.2 x 3.5 = 21.7.

Then, add the exponents: 10² x 10³ = 10^(2+3) = 10^5.

Therefore, the result is 21.7 x 10^5.

Answer:

Length of material needed = 35.8 feet

Step-by-step explanation:

Door of the wooden garage is in the shape of a rectangle with dimensions 16 ft × 8 ft.

Lincoln is going to place two boards in the shape of an X on the door.

From the picture attached,

Diagonals of the rectangular door will be equal in measure.

Therefore, length of the material = 2×(Diagonal of the rectangle)

By applying Pythagoras theorem in the rectangle,

(Diagonal)² = 16² + 8²

Diagonal = \(\sqrt{256+64}\) = 17.89

Therefore, length of material = 2 × 17.89

                                                = 35.77

                                                ≈ 35.8 feet

Step-by-step explanation:

The measure of the angles are 60 degrees each

From the question, we have the following parameters that can be used in our computation:

AOB = 138 degrees

Also, we have:

The line OX bisects the angle AOB

Using the above as a guide, we have the following:

AOX = AOB/2 = 138/2 = 69

Also, we have

XOB = AOB/2 = 138/2 = 69

Hence, the angles are 69 degrees each

Step-by-step explanation:

because if you do long divison

Answer: It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8)

Step-by-step explanation: Dilated triangles are never congruent, only similar (unless the dilation factor is exactly 1).

The coordinates of an image dilated about the origin are those of the pre-image multiplied by the dilation factor. For example,

I took the quiz!

Answer: i think hes correct

Step-by-step explanation:

Only so many prints could be made, each sent to one theater at a time.

Thus, option (C) is correct.

Before the blockbuster era, movie distribution was limited by the number of physical film prints that could be made. Each film had a limited number of copies, and these prints had to be physically shipped to individual theaters. This process took time and limited the number of theaters that could screen a movie simultaneously.

As a result, it was harder for pre-blockbuster-era moviegoers to see movies as soon as they were released because the films were not as widely available in theaters right after their release.

This distribution constraint was a significant factor in controlling the release and accessibility of movies in the pre-blockbuster era.

Thus, option (C) is correct.

The determinant of each of the given matrices are:

1) -4269

2) -1988

3) -68.92

The determinant of a matrix is a number that is specially defined only for square matrices. Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations.

Thus:

1) \(\left[\begin{array}{ccc}7&&31\\142&&19\\\end{array}\right]\)

The determinant of this 2 x 2 matrix is:

(7 * 19) - (142 * 31) = -4269

2) \(\left[\begin{array}{ccc}7&11&21\\55&8&2\\-16&1&-9\end{array}\right]\)

The determinant of this 3 x 3 matrix is:

7((8*-9) - (1*2)) + 11((55*-9) - (2*-6)) + 21((55*1) - (8*-16)) = -1988

3) \(\left[\begin{array}{ccc}5.07&6.02&2.01\\-30.7&2.5&3.5\\3.55&-1.1&2.35\end{array}\right]\)

The determinant of this 3 x 3 matrix is:

5.07[(2.5 * 2.35) - (-1.1 *  3.5)] + 6.02[(-30.7 * 2.35) - (3.5 * 3.55)] + 2.01[(-30.7 * -1.1) - (2.5 * 3.55)] = -68.92

Formula for arc length is 2times pie times radius times angle divided by 360.

Answer:

The answer is option 2.

Step-by-step explanation:

You have to use length or arc formula, Arc = θ/360×2×π×r where θ represents degrees and r is radius. Then substitute the following values into the formula :

\(arc = \frac{θ}{360} \times 2 \times \pi \times r\)

Let θ = 45,

Let r = 12,

\(arc = \frac{45}{360} \times 2 \times \pi \times 12\)

\(arc = \frac{1}{8} \times 24\pi\)

\(arc = 9.42 \: units \: (3s.f)\)

Area of the patio is -6x² + x + 2 square yards and perimeter of the patio is 6 - 2x yards.

A yard is a unit of measurement used to measure length or distance in both the US customary system and the British imperial system. One yard is equal to 3 feet or 36 inches. In the US customary system, a yard is equal to 0.9144 meters, while in the British imperial system, it is equal to 0.9144 meters or 3 feet. Yards are commonly used for measuring larger distances, such as in construction or landscaping, as well as in some sports like American football and cricket.

The area of the rectangular patio is given by multiplying its length by its width, so the area is:

A = (1 + 2x)(2 - 3x)

Now using distributive property we get,

A = 2 - 3x + 4x - 6x²

Simplifying further, we get:

A = -6x² + x + 2

Therefore, the area of the patio is described by the quadratic equation -6x² + x + 2.

To find the perimeter of the patio, we add up the lengths of all four sides. The length and width are given as (1 + 2x) and (2 - 3x), respectively, so the perimeter is:

P = 2(1 + 2x) + 2(2 - 3x)

Simplifying this expression, we get:

P = 2 + 4x + 4 - 6x

P = 6 - 2x

Therefore, the perimeter of the patio is described by the linear equation 6 - 2x.

I'll use x in place of θ

Let's isolate the sine term and then square both sides

3sin(x) + 4cos(x) = 5

3sin(x) = 5-4cos(x)

(3sin(x))^2 = ( 5-4cos(x) )^2

9sin^2(x) = 25-40cos(x)+16cos^2(x)

9sin^2(x) = 25-40cos(x)+16(1-sin^2(x))

9sin^2(x) = 25-40cos(x)+16-16sin^2(x)

9sin^2(x)+16sin^2(x) = 25-40cos(x)+16

25sin^2(x) = 41-40cos(x)

25(1-cos^2(x)) = 41-40cos(x)

25-25cos^2(x) = 41-40cos(x)

Now let w = cos(x), so we now have the following

25-25w^2 = 41-40w

25w^2-40w+41-25 = 0

25w^2-40w+16 = 0

(5w - 4)^2 = 0

5w-4 = 0

w = 4/5

Therefore cos(x) = 4/5

Use the pythagorean theorem or unit circle to find that if cos(x) = 4/5, then it leads to sin(x) = 3/5. This is exactly because of the 3-4-5 right triangle.

Then lastly,

tan(x) = sin(x)/cos(x)

tan(x) = sin(x)  ÷  cos(x)

tan(x) = (3/5)  ÷  (4/5)

tan(x) = (3/5)  *  (5/4)

tan(x) = (3*5)/(5*4)

tan(x) = 3/4

The solution is:  the rate of change is 3.

Here, we have,

Since the graph of f(x) is translated 1 unit down, we need to decrease the value of f(x) by 1 to find g(x):

g(x) = f(x) - 1

f(x) = 3|x| – 4

so, we get,

g(x) = 3|x| – 4 - 1

      = 3|x| – 5

Now, to calculate the rate of change over the interval 2 <= x <= 5, we can use the formula below:

rate = g(5) - g(2)/ 5-2

so, we get,

rate = 9/3 = 3

Therefore the rate of change is 3.
