- Triangle ABC has vertices A(1,2), B(7,0), and
C(3,-2). Prove triangle ABC is an isosceles triangle.
Please help! Thanks
Triangle ABC can be proven to be an isosceles triangle by showing that two of its sides have equal lengths.
To prove that triangle ABC is isosceles, we need to demonstrate that at least two of its sides have equal lengths. Let's calculate the lengths of the sides AB, BC, and AC using the distance formula.
The length of side AB can be found using the coordinates of points A(1,2) and B(7,0):
AB = √((7-1)² + (0-2)²) = √(36 + 4) = √40 = 2√10
The length of side BC can be calculated using the coordinates of points B(7,0) and C(3,-2):
BC = √((3-7)² + (-2-0)²) = √((-4)² + (-2)²) = √(16 + 4) = √20 = 2√5
The length of side AC can be determined using the coordinates of points A(1,2) and C(3,-2):
AC = √((3-1)² + (-2-2)²) = √((2)² + (-4)²) = √(4 + 16) = √20 = 2√5
Comparing the lengths of the sides, we see that AB = AC = 2√10 = 2√5. Therefore, two sides of triangle ABC have equal lengths, indicating that it is an isosceles triangle.

You received someone’s public key as (55, 7), and you want to encrypt the plaintext value of 8. Using RSA encryption, what is the corresponding ciphertext?
The corresponding ciphertext for encrypting the plaintext value of 8 using RSA encryption with a public key of (55, 7) is 32.
RSA encryption is a public-key encryption algorithm that relies on the mathematical properties of prime numbers. In this case, the public key provided consists of two values, (55, 7), where 55 represents the modulus and 7 represents the public exponent. To encrypt the plaintext value of 8, we raise it to the power of the public exponent and take the modulus of the result with the modulus value.
To encrypt the plaintext value of 8, we perform the following calculation:
ciphertext = (plaintext ^ public_exponent) % modulus
= (8 ^ 7) % 55
= 2097152 % 55

What is not one of the three characteristics of tcp in its role as a reliable delivery protocol?.
Transmission Control Protocol (TCP) is the most popular protocol utilized for communication across the internet. TCP, as a reliable delivery protocol, has several characteristics. However, one of the three characteristics of TCP in its role as a reliable delivery protocol is the ability to perform a quick, continuous, and reliable flow control.
The first characteristic of TCP is connection-oriented communication. The connection-oriented communication guarantees that the sending device is connected to the receiving device before data transmission. TCP guarantees that the receiver is ready to receive data before transmission occurs. Therefore, the receiver will have a buffer ready to store incoming data.
Therefore, Flow control is one of the three characteristics of TCP in its role as a reliable delivery protocol. It allows the sender to control the flow of data based on the receiver's buffer size, preventing buffer overflow or congestion.

why do most highlights on plastic objects look white, while those on gold metal look gold
When light is shone on an object, it gets absorbed and reflected by the object’s surface. This is why we see different colors of objects and why most highlights on plastic objects look white, while those on gold metal look gold.
Most highlights on plastic objects look white because the surface of plastic is not as smooth as that of metal. The light is scattered on the rough surface of the plastic object, causing the colors to mix and appear white. As a result, the color of the highlight is lost in the overall whiteness of the scattered light. On the other hand, gold metal is smooth, and light reflects off it more easily.
When light falls on the gold surface, the electrons on the surface of the metal move around, causing the light to reflect in a specific way that creates the color gold. The highlight on the gold metal will also be gold as the surface is smooth, and the light is reflected in a specific way to give it that golden color. In conclusion, highlights on plastic objects look white because the surface of the plastic is rough, while those on gold metal look gold because the surface of the gold metal is smooth, which allows light to reflect in a specific way that creates the color gold.
