for the diagram below which equation is the correct use of the distance formula


the last one D is
D= √(11-6)^2 + (5-y2)^2

For The Diagram Below Which Equation Is The Correct Use Of The Distance Formulathe Last One D Is D= (11-6)^2

Answers

Answer 1
the Answer is A, verified apex 
Answer 2

Answer: The correct equation is,

[tex]6.71=\sqrt{ (11-5)^2+(y_2-6)^2}[/tex]

Step-by-step explanation:

If [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the endpoints of a line segment,

Then by the distance formula,

The length of the line segment is,

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

Here, (5,6) and (11, [tex]y_2[/tex] ) are the endpoint of the line segment which has the length 6.71,

Thus, d = 6.71, [tex]x_1=5[/tex] [tex]y_1=6[/tex], [tex]x_2=11[/tex]

[tex]\implies 6.71 = \sqrt{ (11-5)^2+(y_2-6)^2[/tex]

Which is the required equation.

Keisha has one penny, one nickel, and one dime in her pocket. She randomly takes on coin out of her pocket. Without putting it back, she randomly takes out another coin. If Keisha lists all the possible outcomes of picking the two coins one at a time, how many outcomes are there?

Answers

There are 12 different ways she could take a penny, a nickle, and a dime out of here pocket and only pick 2. What i did was i took 2 and 3 and multiplied them. because i can pick 2 coins, and there are 3 coins in total. After i multiplied them i got 6, then i got 2 and multiplied it by 6 and came out with 12. The reason why i did that is because there are 6 outcomes so far then you have to multiply them by 2 to get all of your complete outcomes. I hope i could help!!! Please give me brainliest!!!

The table below shows the values of y for different values of x:

Which equation shows the relationship between x and y?
x = 5y
y = 5 + x
x = 5 + y
y = 5x

Answers

x y
0 0
1  5
2 10
3 15

The answer is y = 5x
we can check this by plugging in the numbers from the table:
5 = 1(5)
5 = 5
This makes this answer correct because it makes the equation true.

Answer:

D. [tex]y=5x[/tex]

Step-by-step explanation:

We have been given a table of values. We are asked to find the equation that shows the relationship between x and y.

x          y

0         0

1           5

2         10

3         15

Upon looking at our given table, we can see that with each increase in x value, the value of x increases by 5. This means that slope of our given line is 5.

We can also see that initial value or y-intercept is 0.

Upon substituting our given values in slope intercept form of equation, we will get:

[tex]y=5x+0[/tex]

[tex]y=5x[/tex]

Therefore, our required equation is [tex]y=5x[/tex] and option D is the correct choice.

Solve the system of equations algebraically.

a. (8,8)
b. (9,7)
c. many solutions
d. no solution

Answers

The answer is (9,7).

The system of equations has a solution at (9, 7), which is an option (b).

What are Systems of equations?

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

The given equations are:

3x-3y=6

6x-7y=5

Multiply the first equation by 2 to get rid of the coefficient of x in the second equation:

6x - 6y = 12

6x - 7y = 5

Subtract the first equation from the second equation to eliminate x:

0x - y = -7

y = 7

Substitute y = 7 into one of the original equations and solve for x:

3x - 3y = 6

3x - 3(7) = 6

3x - 21 = 6

3x = 27

x = 9

Therefore, the solution to the system of equations is (9, 7), which corresponds to option (b).

hello,

the first computer is usually regarded as one called ROACH completed in 1945. Email was invited in 1971. how many years after the computer was email invented

in this vase we will use soustraction

1971-1945=26

email was invented 26 years after computers

hopes this helped you well
may i please have the brainliest
have a wonderful day or night

Final answer:

Email was invented 26 years after the completion of the first recognized computer in 1945.

Explanation:

The first computer is often attributed to the work carried out during World War II, with machines like ENIAC, completed in 1945, incorporating vacuum tubes and filling entire rooms. However, the question references a machine called ROACH, which seems to be a typo or a misunderstanding; we usually refer to ENIAC as one of the first computers. Email, on the other hand, was invented in 1971 by Ray Tomlinson. Calculating the difference between the years when the first computer was completed and when email was invented gives us the number of years it took for email to be developed after the advent of the computer.

To find this, we subtract the year the first computer was completed, 1945, from the year email was invented, 1971:

1971 (the year email was invited) - 1945 (the year the computer was completed) = 26 years.

Email was invented 26 years after the completion of the first computer.

A square garden has an area of 64 square feet. What is the length of the garden?

Answers

Area = Length x Length

Area = Length²

Length² = 64

Length = √64

Length = 8 feet

Answer: 8 feet

The length of the garden will be 8 feet.

It should be noted that the area of a square is gotten by multiplying its lengths together. For example, the area of a square with length of 2cm will be: = 2 × 2 = 4cm²

Therefore, since the square garden has an area of 64 square feet, the length of the garden will be:

= ✓64

= 8 feet

Therefore, the length is 8 feet.

Parker was able to pay for 44% of his college tuition with his scholarship.
The remaining $10,054.52 he paid for with a student loan.
What was the total cost of Parker's college tuition?
Round your answer to the nearest dollar.
Tuition cost = $_

Answers

The total cost is $17,955.

Let x be the total amount of his tuition.  He paid for 44% of it, or 0.44, with his scholarship. This leaves 100%-44% = 56% = 0.56 of it to be taken care of with loans.  We know he took out 10054.52 in loans:

0.56x = 10054.52

Divide both sides by 0.56:
0.56x/0.56 = 10054.52/0.56
x = 17954.50 ≈ 17955
Final answer:

The total cost of Parker's college tuition, rounded to the nearest dollar, is $17,952.

Explanation:

If Parker was able to pay for 44% of his total college tuition with his scholarship, this means that the $10,054.52, which he paid using his student loan, represents the remaining 56% of his tuition cost. Therefore, to find the total cost of tuition, we need to divide the amount he paid with a loan by 0.56. Performing this calculation gives us:

$10,054.52 / 0.56 = $17,952.00

Therefore, the total cost of Parker's tuition rounded to the nearest dollar is $17,952.
