What is the distance between the points (2,7) and (-2,7)

Answer:

489

Step-by-step explanation:

Answer:

No, because there is no whole number that when multiplied by itself gives 125

Step-by-step explanation:

The square root of 125 is 11.1803.

Some additional info:

[tex]\sqrt{125}=\sqrt{25 * 5} =5\sqrt{5}[/tex]

Hence, it is not a perfect square

No, because there is no whole number that when multiplied by itself gives 125.

To determine if 125 is a perfect square, we need to find a whole number that, when multiplied by itself gives 125.

We will try some numbers:

Since there is no whole number that, when multiplied by itself, equals 125, we will conclude that 125 is not a perfect square.

Answer: Wayne is 35, Mark is 34, and Stan is 33.

33+34+35 = 102

Stan is 33 years old, Mark is 34 years old, and Wayne is 35 years old.

Let's solve the problem step by step:

Let's assume Stan's age to be x.

According to the given information, Mark's age is one more than Stan's age, so Mark's age is x + 1.

Similarly, Wayne's age is one more than Mark's age, so Wayne's age is (x + 1) + 1 = x + 2.

Now we know that the sum of their ages is 102, so:

x + (x + 1) + (x + 2) = 102

Combining like terms, we get:

3x + 3 = 102

Simplifying the equation, we get:

3x = 99

Dividing both sides by 3, we get:

x = 33

Now we can substitute the value of x in the previous equations:

Stan's age = 33

Mark's age = 33 + 1 = 34

Wayne's age = 34 + 1 = 35

So, Stan is 33 years old, Mark is 34 years old, and Wayne is 35 years old.

Answer:

Width = 12 cm

Length = 14 cm

Step-by-step explanation:

Rectangle:

Let the width  = x cm

So, the length = (x+2) cm

Perimeter  = 52 cm

2 *(l+b) = 52

2 *(x+2  + x) =  52

   2 * ( 2x + 2) = 52

           2x + 2  = 52/ 2

           2x + 2  = 26

                 2x = 26- 2

                  2x = 24

                    x = 24/2

                    x = 12

Width = 12 cm

Length = 14 cm

Answer: The graph is attached.

Step-by-step explanation:

 We must design a graph so that the x-axis represents the Time in hours and the y-axis represents the Height in feet.

The plane takes off from this point:

[tex]A(0,0)[/tex].

We know that the plane climbs steadily for 30 minutes (which is 0.5 hours) until it reaches 40000 feet. Then, we can identify another point; this is:

[tex]B(0.5,\ 40000)[/tex]

It travels at that altitude for 2 hours (which indicates a horizontal line) and then it begins to descend to land, giving us another point:

[tex]C(2.5\ 40000)[/tex]

This takes 15 minutes (which is 0.25 hours) at a constant rate. Then, we get a final point:

[tex]D(2.75,\ 0)[/tex]

Knowing these points, we can draw the graph (Observe the image attached)

Answer:

43

Step-by-step explanation:

The first three numbers are perfect squares:

9 = 3²

16 = 4²

25 = 5²

43 is not a perfect square.

43 does not belong because it cannot ve expressed as perfect square

Perfect numbers are squares of any integer

Given the sequence of numbers 9, 16, 25, 43

From the sequence we can see that the first 3 numbers are perfect squared written as 3², 4², 5², 43

We can see that 43 cannot be expressed as perfect square making it the odd one out of the numbers

Answer:

a=200

b=80

I think this would be the answer

if not im sorry.

Using the principle of inclusion-exclusion, we determine that 80 employees use both work and private emails for correspondence. There are 120 employees in violation of company policy to use only their company email for business correspondence.

To solve the question, we can use the principle of inclusion-exclusion. First, we need to find the total number of people who use at least one type of email (work or private). Then we subtract the total number of people who use both to find those who are in violation of company policy.

Part (a)

Let A be the number of employees using work email, B be the number using private email, and C be the number not using email at all.

We know that A = 280, B = 200, and C = 40. We also have a total T = 400 employees.

Employees using both work and private email, represented as AB, can be found by: T - (A + B + C).

AB = 400 - (280 + 200 + 40)

AB = 400 - 520

AB = -120

However, since we cannot have negative users, this means that AB must be equal to 280 + 200 - 400 = 80. Therefore, 80 employees use both their work and private email for correspondence.

Part (b)

To find out how many are in violation of the policy, we just consider the number using private emails, minus those who use both emails (because they also use company email).

Violation = B - AB

Violation = 200 - 80

Violation = 120

Thus, there are 120 employees in violation of company policy regarding email use.

Final answer:

The maximum number of hours a tutor can work at $35 an hour within a $420 budget is 12 hours per month.

Explanation:

The student asked how many hours a math tutor could work each month within a budget of $420 if the tutor charges $35 an hour. To calculate the maximum number of tutoring hours, divide the total budget by the hourly rate. This can be expressed as Maximum Hours = Total Budget / Hourly Rate.

In this case, the calculation would be:

Maximum Hours = $420 / $35 per hour

So, the math tutor can work a maximum of 12 hours per month on this budget since:

$420 / $35 per hour = 12 hours

Answer:

2x - y = 7

Step-by-step explanation:

Parallel lines have the same slope and the equation will have the same form

That is

2x - y = c ← c will have different values depending on the point it passes through.

Here the line passes through (3, - 1 ) , thus substituting into the left side

2(3) - (- 1) = 6 + 1 = 7 ← value of c, hence

2x - y = 7 ← equation of line

The line's equation is y = 2x - 7.

In geometry, the coplanar straight lines that do not intersect at any point are called parallel lines. The slopes of parallel lines are equal because they are equally inclined with the positive x-axis.

The equation of the given line is

2x-y = 6

i.e. y = 2x-6

We know that If the equation of a line can be expressed as y = mx+c, then the slope of this line is m.

So, the slope of this given line is 2.

We can assume that the equation of the line which is parallel to the given line can be written as

y = 2x + c ...(1)

, where c is a constant.

Since this line passes through the point (3, -1), you have to put x = 3 and y = -1 in (1), to get the value of the constant.

Now, c = y - 2x = (-1) - 2*3 = (-1) - 6 = -7

Putting this value in (1), we get

y = 2x - 7

Therefore the required equation of the line is y = 2x - 7.

Answer:

76

Step-by-step explanation:

When you solve the equation you will do parentheses first (10+2) which equals 12 then you carry everything down. Next you will multiply 3 x 12 to get 36 then you carry the 20 and  2 down. Next you will multiply 20 by 2 to get 40 and then add 36 + 40 to get 76.

3(10+2) +20 x 2

3(12) +20 x 2

36 + 20 x 2

36 + 40

76 : answer

The expression 3⋅(10+2)+20⋅2 simplifies to 76.

The given expression is [tex]$$3 \cdot (10+2) + 20 \cdot 2[/tex]

Let's simplify it step by step:

1. First, perform the operation inside the parentheses: [tex]3 \cdot 12 + 20 \cdot 2[/tex]

2. Then, perform the multiplication: [tex]36 + 40[/tex]

3. Finally, perform the addition: [tex]76[/tex]

The range of values for the measurement 300 ±2% is 294 to 306. This involves considering the concept of accuracy and precision in measurements.

The question is asking for the range of measurements that can be made if the measurement is 300 units with a 2% uncertainty. In mathematical terms, an uncertainty of 2% means we can make measurements that are 2% less or 2% more than the given value.

First you must calculate 2% of 300 to find the value representing the uncertainty. This is (2/100) * 300 = 6. Hence, the measurement can be 6 units less than or more than 300.

Therefore, the range of measurements we can make is from (300 - 6) to (300 + 6). This results in a range of 294 to 306.

This concept is grounded in accuracy and precision. Accuracy describes the close proximity of a measurement to a specific value, while precision relates to the consistency of output using the same measurement process.

Answer:

k=8

The problem:

The function y=2x+2 and y=-x+k intersect at the point (2,6).

Find the value of k.

Step-by-step explanation:

(2,6) is a point contained by both y=2x+2 and y=-x+k.

Let's see if it actually on y=2x+2.

x=2,y=6

y=2x+2

6=2(2)+2

6=4+2

6=6 is true so it (2,6) is on y=2x+2.

Now we want k such that (2,6) is on y=-x+k.

6=-2+k

Add 2 on both sides:

8=k

So k=8.

Answer:

k = 8

Step-by-step explanation:

y = 2x + 2    

y = -x + k

2x + 2  = - x +k

3x = k - 2

x= 2 : k-2= 6

k = 8
