Which shape does NOT have rotational symmetry?
A B C D

Answer:

the answer isssssssssssssß

Answer:

A

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\(\frac{LM}{LU}\) = \(\frac{LN}{LT}\) , substitute values

\(\frac{3x+12}{25}\) = \(\frac{45}{25}\) ( cross- multiply )

25(3x + 12) = 1125 ( divide both sides by 25 )

3x + 12 = 45 ( subtract 12 from both sides )

3x = 33 ( divide both sides by 3 )

x = 11 → A

Answer:

\(x=14\)

Step-by-step explanation:

\(4\) divided by the sum of \(x\) and \(2\), in math lingo, is \(4/(x+2)\). The quotient of \(3\) and the difference of \(x\) and \(2\), in math lingo, is \(3/(x-2)\).

We have that these two quantities are equal, so \(4/(x+2)=3/(x-2)\).

We can multiply both sides of the equation by \((x+2)(x-2)\) to get \(4(x-2)=3(x+2)\).

We can distribute both sides of the equation to get \(4x-8=3x+6\).

We can subtract \(3x\) from both sides of the equation to get \(x-8=6\).

We can then add \(8\) to both sides of the equation to get \(x=14\).

So, the answer is \(\boxed{x=14}\) and we're done!

Answer:

Step-by-step explanation:

It is given that the area of a circle is 36.43cm² and we have to find the length of the radius.

So, first of we must know this formula :

⇒ πr² = Area(Circle)

Now, Substituting the given values in the formula :

⇒ 3.14 × r² = 36.43

⇒ r² = 36.43/3.14

⇒ r² = 11.60

⇒ r = √11.60

⇒ r = 3.40

Therefore,

Hey ! there

Answer:

Step-by-step explanation:

In this question we are given with area of circle that is 36.43 cm² . And we are asked to find the length of radius of circle rounded to two decimal points .

We know that ,

\( \qquad \quad \frak{Area_{(Circle)} = \pi r {}^{2} } \quad \bigstar\)

Where ,

Solution : -

According to question , area of Circle is equal to 36.43 . So ,

\( \longrightarrow \qquad \: \pi r {}^{2} = 36.43\)

Step 1 : Substituting value of π :

\( \longrightarrow \qquad \:3.14 \times r {}^{2} = 36.43\)

Step 2 : Transposing 3.14 to right side :

\( \longrightarrow \qquad \: r {}^{2} = \cancel{\dfrac{36.43}{3.14} }\)

On dividing 36.43 by 3.14 , We get :

\( \longrightarrow \qquad \: r {}^{2} = 11.60\)

Step 3 : For removing square from r , We are applying root on both sides :

\( \longrightarrow \qquad \: \sqrt{r {}^{ 2 }} = \sqrt{ 11.60}\)

We get :

\( \longrightarrow \qquad \:r = \sqrt{11.60} \)

Step 4 : Finding square root of 11.60 , We get :

\( \longrightarrow \qquad \: \purple{\underline{\boxed{\frak{r = 3.40 \: cm}}}} \)

Answer:

Slope and y intercept.

Step-by-step explanation:

This is necassary to write the equation of a line in y=mx+b

m is where the slope goes, and b is the y intercept.

Alternatively, you could also write the equation for a line with a point on the line and the slope.

You would then write it in point slope formula:

y-y1=m(x-x1)

This can later be converted into slope intercept form.

Answer:

When asked to write an equation, you need to know two things – slope (m) and y-intercept (b).

Or

The Standard Form for a linear equation in two variables, x, and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

Answer:

36, 38, 40, 42, 44

Step-by-step explanation:

We can denote an even number as 2n (where n is a natural number).

Each consecutive even number will be 2 more than the previous number.

Let 1st number = 2n

⇒ 2nd number = 2n + 2

⇒ 3rd number = 2n + 4

⇒ 4th number = 2n + 6

⇒ 5th number = 2n + 8

Sum of all 5 numbers is 200.  

⇒ 2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 200

⇒ 10n + 20 = 200

⇒ 10n = 180

⇒ n = 18

If n = 18, then 2n = 36

Therefore, the numbers are 36, 38, 40, 42, 44

The mathematical measure of standard deviation is essential for risk managers as it helps quantify the dispersion or variability of data, enabling them to assess and manage potential risks effectively.

Standard deviation is a statistical tool used to measure the amount of variation or dispersion in a set of data points. In the context of risk management, standard deviation provides a measure of how much an investment's returns deviate from its average return. This information is crucial for risk managers as it helps them assess the volatility and uncertainty associated with an investment or portfolio.

By analyzing the standard deviation, risk managers can gain insights into the potential risks and fluctuations in returns, allowing them to make informed decisions regarding asset allocation, risk tolerance, and hedging strategies. Furthermore, standard deviation enables risk managers to compare and evaluate different investments based on their level of risk, supporting the process of portfolio diversification and risk mitigation.

Val dove 2.5 times farther than her friend.

To represent the difference in depth between Val and her friend, we can subtract their respective depths. Val's depth is -119 feet, and her friend's depth is -34 feet.

The equation to represent the difference in depth is:

Val's depth - Friend's depth = Difference in depth.

(-119) - (-34) = Difference in depth.

To subtract a negative number, we can rewrite it as adding the positive counterpart:

(-119) + 34 = Difference in depth.

Now we can simplify the equation:

-85 = Difference in depth.

The result, -85, represents the difference in depth between Val and her friend. However, since the question asks for how many times farther Val dove compared to her friend, we need to express the result as a multiplication equation.

Let's represent the number of times farther Val dove compared to her friend as 'x'. We can set up the equation:

Difference in depth = x * Friend's depth.

-85 = x * (-34).

To solve for x, we divide both sides of the equation by -34:

-85 / -34 = x.

Simplifying the division:

2.5 ≈ x.

Therefore, Val dove approximately 2.5 times farther than her friend.

Calibration needs to be performed periodically or whenever there is a significant change in the camera's setup, as it may affect the accuracy of the camera's measurements.

The following is an explanation of the same:

1. Place the large cubic frame (4 meters in size) on the road several meters in front of the robot vehicle. This cubic frame will act as a calibration target for the camera.

2. Define the positions of the eight corners of the cubic frame with respect to a world coordinate system. The world coordinate system has its axes parallel to the cube edges, and its origin is at the center of the cube.

3. To calibrate the camera, we need to find the world coordinates of the cube vertices. The vertices of a cubic frame with a 4-meter side length and the origin at the center will have the following world coordinates:

  Vertex 1: (-2, -2, -2)
  Vertex 2: (2, -2, -2)
  Vertex 3: (2, 2, -2)
  Vertex 4: (-2, 2, -2)
  Vertex 5: (-2, -2, 2)
  Vertex 6: (2, -2, 2)
  Vertex 7: (2, 2, 2)
  Vertex 8: (-2, 2, 2)

4. Capture an image of the cubic frame with the camera on the robot vehicle.

5. Use the linear method described in the lectures to determine the relationship between the camera's image coordinates and the world coordinates. This involves estimating the intrinsic and extrinsic parameters of the camera.

6. Once the camera parameters are estimated, you have successfully calibrated the camera of the robot vehicle using a linear method and a cubic frame.

Answer:

149.49° (nearest hundredth)

Step-by-step explanation:

To calculate the direction of the plane's resultant vector, we can draw a vector diagram (see attachment).

Since the two vectors form a right angle, we can use the tangent trigonometric ratio.

\(\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$ \tan x=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $x$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}\)

The resultant vector is in quadrant II, since the plane is travelling north (positive y-direction) and then west (negative x-direction).

As the direction of a resultant vector is measured in an anticlockwise direction from the positive x-axis, we need to add 90° to the angle found using the tan ratio.

The angle between the y-axis and the resultant vector can be found using tan x = 767 / 452. Therefore, the expression for the direction of the resultant vector θ is:

\(\theta=90^{\circ}+\arctan \left(\dfrac{767}{452}\right)\)

\(\theta=90^{\circ}+59.4887724...^{\circ}\)

\(\theta=149.49^{\circ}\; \sf (nearest\;hundredth)\)

Therefore, the direction of the plane's resultant vector is approximately 149.49° (measured anticlockwise from the positive x-axis).

This can also be expressed as N 59.49° W.

Since the loan is at a simple interest rate of 8% for 5 years, the total amount that the mysterious hand will pay is:

Total amount = Principal + Interest

where Principal is the initial amount of the loan, and Interest is the amount of interest charged on the loan.

The interest charged on the loan can be calculated using the simple interest formula:

Interest = Principal x Rate x Time

where Rate is the interest rate per year, and Time is the time period in years.

Plugging in the given values, we get:

Interest = 6600 x 0.08 x 5 = 2640

So the total amount that the mysterious hand will pay is:

Total amount = 6600 + 2640 = 9240

The slope of the equation y=32,500x means the probe is traveling at 32,500 miles per hour.

2.5 hours after launch, the distance to the probe is 81,250 miles from Earth's surface.

Distance is a numerical or sometimes qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance can represent an estimate based on physical length or other criteria (eg "two more counties"). Most of these concepts of physical and metaphorical distance are formulated in mathematics using the concept of metric space.

Probe runs vertically, hence letter "y". As stated in the question, units of y are miles.

According to the Question:

Time is represented by "x" in hours. The distance the probe travels is given by the equation y = 32 500x. This means that the probe covers "y" distance in "x" time. So, the tilt represents the speed of the probe in miles per hour, which means the probe is traveling at 32,500 miles per hour.

Now,

the probe distance for 2.5 hours is

y = 32 500x

Substitute 2 in the x value.

We get y as 81,250 miles.
