write a polynomial in standard form that represents the area of the shaded region

2 dilated means that the measurement of an area has increased or expanded in size.

This can be a linear measurement such as the diameter of a circle, or the area of a square or rectangle. The formula for the area of a circle is A=πr2 where r is the radius of the circle. A 2 dilated measurement would mean that the radius has doubled, so the formula would be A=π(2r)2 A=4πr2. This would mean that the area of the circle has increased by a factor of 4. Similarly, if the length and width of a rectangle were 2 dilated, the area would be A=2L2W, which would be four times the original area.

1) X-Rays are dangerous because: "They have short wavelengths that can penetrate materials, and their high energy can damage matter."  (Option B)

2) From the table given, the wave that has the lowest energy is Wave 4.

The relationship between frequency and wavelength is inverse. The wavelength of the wave with the highest frequency is the shortest. One-half the wavelength equals twice the frequency. As a result, the wavelength ratio is inverse to the frequency ratio.

To summarize, waves transport energy. The quantity of energy carried by them is proportional to their frequency and amplitude. The greater the frequency, the greater the energy, and the greater the amplitude, the greater the energy.

Also, the lower the frequency, the lower the energy, and the lower the amplitude, the lower the energy. Thus, the wave with the lowest energy is Wave 4.

Answer: 216.67 meters/ min

Step-by-step explanation: Converting 13 km/h to meters per minute

First, we will convert 13 km to meters

So, we know 1 km = 1000 meters

Then 13 km/ h =  x

x = 1000 multiplied 13

x = 13,000 meters/ h

Now, we will convert to hours to minutes

We know 1 h = 60 min

Then 13,000 meters/ 60 min

That = 216.667 meters/ min

After approximating

Answer = 216.7 meters / min

a) Tunnel A is a circle with center (-14, 0) and radius 12, meaning that both the width and the height are of 12.

b) Tunnel B is a parabola that has a width of 32 feet and a height of 16 feet.

c) The maximum height of Tunnel A is of 12 feet and of Tunnel B is of 16 feet, hence, since the height of the truck is of 13.5 feet, it can pass through Tunnel B without damage, as it's height is greater than 13.5 feet.

The equation of a circle of center  and radius r is given by:

(x-x₀) +(y-y₀) = r²

For Tunnel A, the equation is given by:

x² + y² + 28x + 52 = 0

Completing the squares:

(x + 14)² + y² = -52 + 14²

(x + 14)² + y² = 144.

Tunnel A is a circle with center (-14, 0) and radius 12, meaning that both the width and the height are of 12.

A quadratic equation is modeled by:

y = ax^2 + bx + c

For Tunnel B, the equation is given as follows:

x² - 36x + 16y + 68 = 0.

16y = -x² + 36x - 68.

Simplifying by 16:

y = -0.0625x² + 2.25x - 4.25.

Hence the coefficients are a = -0.0625, b = 2.25, c = -4.25, and the maximum height is:

y₀=(2.25)²-49-0.0625)(-1.25)/4(-0.0625) = 16

The width is the difference between the roots, which, using a calculator, are: 2 and 34, hence the width is of 32 feet.

This implies that the tunnel B is a parabola that has a width of 32 feet and a height of 16 feet.

For item c, we have that:

The maximum height of Tunnel A is of 12 feet and of Tunnel B is of 16 feet, hence, since the height of the truck is of 13.5 feet, it can pass through Tunnel B without damage, as it's height is greater than 13.5 feet.

This square pyramid has a volume of 48 cm³.

The term "square pyramid" refers to a three-dimensional geometric form with a square base and four faces or sides that are triangular and meet at a single point (called the vertex). Its five faces give it the name "pentahedron."

The proof is given below

We can start by using the definition of the trigonometric functions cosec(A), tan(A), and cot(A):

cosec(A) = 1/sin(A)

tan(A) = sin(A)/cos(A)

cot(A) = 1/tan(A) = cos(A)/sin(A)

Now, we can substitute these definitions into the equation:

cosec(A)/(tan(A) + cot(A)) = 1/sin(A) / (sin(A)/cos(A) + cos(A)/sin(A))

Simplifying the right-hand side gives us:

1/sin(A) / (sin(A)(1/cos(A) + 1/sin(A))) =

1/sin(A) / (sin(A)/sin(A)cos(A) + sin(A)) =

1/sin(A) / (1 + sin(A))

Finally,

multiplying both sides by sin(A) (which is not 0 because A is not a multiple of pi/2)

cosec(A)/(tan(A) + cot(A)) * sin(A) = 1/sin(A) / (1 + sin(A)) * sin(A) = 1 / (1 + sin(A)) * sin^2(A) = cos(A)

Therefore, cosec(A)/(tan(A) + cot(A)) = cos(A)

The distance up the building that the ladder would reach, given the ladder height and the base of the building, is 13.4 ft.

To find out how far up the building the ladder reaches, we can use the Pythagorean theorem. The theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

Assuming the height that the ladder reaches is x, the formula would be:

x ² + 4 ² = 14 ²

x ² = 14 ²  - 4 ²

x ² = 196 - 16

A line can be represented in the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

Given that m = −72 and the y-intercept is 12, we can represent the line as y = −72x + 12

We are also given that the point (x, 5) lies on the line. So we can substitute the x and y values of the point into the equation of the line to find the value of x.

y = −72x + 12

5 = −72x + 12

-7 = -72x

x = 7/72

So the value of x is 7/72.

We can also get this by solving the equation of the line for x.

y = -72x + 12

y - 12 = -72x

(y - 12)/-72 = x

x = (y - 12)/-72

So for any point (x, y) on the line, the value of x can be obtained by substituting y and the slope-intercept form equation.
