Answer:

x=6

Step-by-step explanation:

triangles CDB and ADB are equal so we know that CD=AD and can write this equation:

3x+5 = 5x-7

subtract '3x' from each side:

5 = 2x-7

add 7 to each side:

12 = 2x

12/2 = x

6=x

The area of the region inside the rectangle that surrounds the square is 147 square in.

The side of square is 10 in

Area of square is = side x side

A = 10 x 10

A = 100 square in.

Therefore, Area of square  is 100

The length of rectangle is 19 in and width of rectangle is 13in

area of rectangle  = l x w

A = 19 x 13

A = 247 square in.

Area of rectangle is 247 square in.

To calculate area of the region inside the rectangle that surrounds the square,

= A[rectangle] - A[square]

= 247 - 100

= 147 square in.

Therefore, The area of the region inside the rectangle that surrounds the square is 147 square in.

Both graphs are horizontal lines. √2 is about 1.414, so is less than 2. On a coordinate plane with values of y increasing in the "up" direction, y=1.414 will be graphed below y=2.

4x−2y=14

Step-by-step explanation:

Answer:

The solution to the system of linear equations is x = 4, y = 1.

Step-by-step explanation:

Given system of linear equations:

\(\begin{cases}4x-2y=14\\y=\dfrac{1}{2}x-1\end{cases}\)

To solve the system of linear equations by the method of substitution, substitute the second equation into the first equation:

\(\implies 4x-2\left(\dfrac{1}{2}x-1\right)=14\)

Solve the equation for x:

\(\implies 4x-x+2=14\)

\(\implies 3x+2=14\)

\(\implies 3x=12\)

\(\implies x=4\)

Substitute the found value of x into the second equation and solve for y:

\(\implies y=\dfrac{1}{2}(4)-1\)

\(\implies y=2-1\)

\(\implies y=1\)

The answer is :

The volume of the replacement cone holds 4·π cubic inches more than the volume of the original cone.

The given measurements of the cones are;

The volume of cone, V = (\(\frac{1}{3}\))·π·r²·h

The volume of an original cone, V₁ = (\(\frac{1}{3}\))·π·r₁²·h₁

∴ V₁ = (\(\frac{1}{3}\)) × π × (3)² × 4 ≈ 37.7 in.³

The replacement cone's volume is, V₂ = (\(\frac{1}{3}\))·π·r₂²·h₂

∴ V₂ = (\(\frac{1}{3}\)) × π × (4)² × 3  ≈ 50.27 in.³

The volume ratio of the cone  = V₁/V₂

∴ Volume ratio = (\(\frac{1}{3}\)) × π × (3)² × 4 in. /((\(\frac{1}{3}\)) × π × (4 )² × 3) = 3/4

The difference in volume of two cone, ΔV = V₂ - V₁ = (\(\frac{1}{3}\)) × π × ((4)² × 3- (3 )² × 4  = 4·π in.³

Therefore, the volume of the replacement cone is 4·π cubic inches more than the volume of the original cone.

The change in the area of the surface of the cube when its side length triples from s units to 3s units is 52s³.

To quantify the change in the area of the surface of a cube when its side length triples from s units to 3s units, we can set up an integral.

Let's denote the side length of the cube as "x". The initial side length is "s" and the final side length is "3s". We want to find the change in surface area, which is the difference between the final surface area and the initial surface area.

The surface area of a cube with side length "x" is given by 6x², as each face of the cube has an area of x² and there are 6 faces.

The change in surface area can be calculated as:

ΔA = ∫(6x²) dx,

where the integral is taken from the initial side length "s" to the final side length "3s".

Now let's evaluate the integral:

∫(6x²) dx = 2x³ + C,

where C is the constant of integration.

To find the change in surface area, we substitute the limits of integration:

ΔA = [2x³]s to 3s

= 2(3s)³ - 2s³

= 2(27)s³ - 2s³

= 52s³

Therefore, the change in the area of the surface of the cube when its side length triples from s units to 3s units is 52s³.

Adjacent angles are two angles that lie in the same plane and have a common vertex and a common side but have no common interior points.

The terms adjacent, neighboring, contiguous, and juxtaposed all denote being close by. Although adjacent might indicate a touch or not, it is usually assumed that there is nothing of the same sort in between. a home with a garage close by. Adjoining clearly means coming together and touching at a certain location or line.

When two angles have a similar vertex and side, they are referred to as neighboring angles. The vertex of an angle is the point at which the rays that make up its sides come to a stop. When adjacent angles have the same vertex and side, they might be a complimentary angle or supplemental angle.

Thus, adjacent angles are two angles that lie in the same plane and have a common vertex and a common side but have no common interior points.

Experimental and quasi-experimental designs share similarities in terms of their focus on investigating cause-and-effect relationships. These designs both involve manipulating variables and observing their effects on an outcome of interest.

However, they differ in terms of the level of control the researcher has over the assignment of participants to groups. Experimental designs are characterized by the random assignment of participants to different groups or conditions. This randomization helps ensure that any observed differences between groups can be attributed to the manipulation of the independent variable. The researcher has control over the assignment process, allowing for stronger causal inferences. Quasi-experimental designs, on the other hand, lack the random assignment of participants to groups. This may be due to practical or ethical reasons. Instead, participants are assigned to groups based on pre-existing characteristics, such as age or location. While quasi-experimental designs still allow for the examination of cause-and-effect relationships, they are considered less rigorous than experimental designs due to the potential for confounding variables. In summary, experimental and quasi-experimental designs both aim to investigate cause-and-effect relationships. They differ primarily in the level of control the researcher has over participant assignment. Experimental designs use random assignment for greater control, while quasi-experimental designs rely on pre-existing characteristics.

The distance between two speakers is important in understanding the phenomenon of interference. In this scenario, we have two loudspeakers, A and B, emitting sinusoidal waves in phase. The frequency of the waves emitted by each speaker is 600 Hz. To move to a point of destructive interference, you need to walk a distance equal to an odd multiple of half the wavelength towards speaker B.

You are standing between the speakers along the line connecting them, and you are at a point of constructive interference.

Constructive interference occurs when the crests of the waves from both speakers align, resulting in a reinforcement of the sound waves. In this case, you are experiencing maximum sound intensity at your position. To move to a point of destructive interference, where the crests of one wave align with the troughs of the other wave, you need to walk towards speaker B.

To determine the distance you need to walk, we can use the concept of the path difference. The path difference is the difference in the distance traveled by the waves from each speaker to reach a given point. In the case of destructive interference, the path difference between the waves from speakers A and B must be equal to an odd multiple of half the wavelength.

Since the frequency is 600 Hz, the wavelength can be calculated using the formula λ = c/f, where c is the speed of sound (approximately 343 m/s) and f is the frequency. Thus, the wavelength is approximately 0.572 m.

For destructive interference, the path difference should be an odd multiple of half the wavelength. Therefore, you need to walk a distance equal to (2n + 1) * λ/2 towards speaker B, where n is an integer.

Let's consider a few examples:

1. If you walk 0.286 m (half the wavelength) towards speaker B, you will reach a point of destructive interference.
2. If you walk 0.572 m (one full wavelength) towards speaker B, you will also reach a point of destructive interference.
3. Similarly, if you walk 1.146 m (two full wavelengths) towards speaker B, you will reach a point of destructive interference.

In conclusion, to move to a point of destructive interference, you need to walk a distance equal to an odd multiple of half the wavelength towards speaker B.
