Find the coordinates

Find The Coordinates

Answers

Answer 1

Given:

The two points are P(14,16) and Q(21,19).

M is the midpoint of the segment PQ.

To find:

The distance between P and Q, and find the coordinates of point M.

Solution:

Distance between P(14,16) and Q(21,19) is

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d(P,Q)=\sqrt{(21-14)^2+(19-16)^2}[/tex]

[tex]d(P,Q)=\sqrt{(7)^2+(3)^2}[/tex]

[tex]d(P,Q)=\sqrt{49+9}[/tex]

On further simplification, we get

[tex]d(P,Q)=\sqrt{58}[/tex]

[tex]d(P,Q)=\sqrt{58}[/tex]

The midpoint of P and Q is M. So, the coordinates of the midpoint are:

[tex]M=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]M=\left(\dfrac{14+21}{2},\dfrac{16+19}{2}\right)[/tex]

[tex]M=\left(\dfrac{35}{2},\dfrac{35}{2}\right)[/tex]

[tex]M=\left(17.5,17.5\right)[/tex]

Therefore, the distance between P and Q is [tex]\sqrt{58}[/tex] and the midpoint of P and Q is [tex]M=\left(17.5,17.5\right)[/tex].

Which graph shows a dilation?

Answers

answer:

now correct me if i am wrong but i think that graph number one is the graph showing a dilation

now i totally forgot now to explain dilations in graphs but if you need anymore help, feel free to ask me!

hope this helps :)

The graph that shows a dilation is the graph on the left which is the 2nd option in the given figure.

A dilation is a transformation that changes the size of an object, but not its shape. The scale factor is a number that tells you how much the object is being enlarged or shrunk. A scale factor of 2 means that the object is being enlarged twice as large, while a scale factor of 0.5 means that the object is being shrunk to half its size.

The graph that shows a dilation is the graph on the left. The scale factor of the dilation is 2, so the object is being enlarged twice as large. The other two graphs do not show a dilation because the objects are being changed in shape.

The graph on the right shows a rotation of the square by 90 degrees. The graph in the middle shows a stretching of the square horizontally. Neither of these transformations are dilations because they change the shape of the object.

Read the article "Overcoming Difficulties: How Helen Keller Learned to Communicate" and answer the question.Every day, millions of people worldwide use their mouths to speak, their ears to hear, and their eyes to see. However, not all people have those abilities. Some are born without the ability to speak, see, or hear. Others lose one or all of these abilities due to illness or accident. Not being able to communicate can be a major obstacle, but people who overcome these challenges are often determined, resourceful, and dedicated to helping others. Instead, people who have to overcome these challenges are often determined, resourceful, and dedicated to helping others.A Great TeacherOne person who did not allow her disability to limit her was Helen Keller. Keller, who became blind and deaf at the age of one and a half due to illness, learned at a very young age that her life was going to be different. As a child in the late 1800s, she did not have access to the technology we have today that assists people with disabilities in their daily lives. Instead, she had a very dedicated and creative teacher who stuck with Keller throughout her life. This teacher's name was Anne Sullivan. As a result of Sullivan's dedication and Keller's own determination, she learned when many thought she could not.Learning How to CommunicateSullivan helped her learn to communicate by using the resources and abilities Keller did have. Keller could touch, taste, and smell. Sullivan taught her to associate hand movements with words. She would spell words on Keller's hand while having her touch the related object. By associating a physical object with the hand movements, Helen learned the meaning of countless words. Learning to speak was tackled in a similar way. By feeling lips as they moved, Keller learned how to use her lips to form words. Using such innovative techniques and the resources available to her opened whole new worlds for Keller's learning. Sullivan encouraged and mentored Keller, never letting her give up and always believing the best for her.An Inspiration to OthersAnother way Keller learned to communicate was through writing. As an adult, she attended Radcliffe College, which allowed her to advance her education, even though many people doubted her ability to be successful. While she was there, she wrote her autobiography, which told the world about her struggles and accomplishments. She was able to share her story through Braille, a form of writing using raised dots felt with the fingers. Throughout her entire college career, Anne Sullivan was beside her, encouraging Keller and interpreting the words she could not see and the sounds she could not hear. Helen Keller's perseverance and Anne Sullivan's dedication became an inspiration for many children and adults around the world.Helen Keller went on to be a successful author and teacher. She became a mentor to other children and adults living with disabilities. To this day, Keller is remembered for her determination, resourcefulness, and dedication that helped her to overcome obstacles and inspire others.
