What is the distance formula?

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

d = distance

(x_1, y_1) = coordinates of the first point

(x_2, y_2) = coordinates of the second point

(4,9)=(x_1,y_1)

(-4,-9)=(x_2,y_2)

\(d = \sqrt{(-4 - 4)^2 + (-9-9)^2}\\d=\sqrt{(8)^2+(18)^2} \\d=2\sqrt{97}\\ d=19.69\)

What is the range of the function g(x) = |x – 12| – 2?

{y | y > –2}
{y | y > –2}
{y | y > 12}
{y | y > 12}

Answers

The range of the function g(x) = |x - 12| - 2 is {y | y > -2}, indicating that the function can take any value greater than -2.

To find the range of the function g(x) = |x - 12| - 2, we need to determine the set of all possible values that the function can take.

The absolute value function |x - 12| represents the distance between x and 12 on the number line. Since the absolute value always results in a non-negative value, the expression |x - 12| will always be greater than or equal to 0.

By subtracting 2 from |x - 12|, we shift the entire range downward by 2 units. This means that the minimum value of g(x) will be -2.

Therefore, the range of g(x) can be written as {y | y > -2}, which means that the function can take any value greater than -2. In other words, the range includes all real numbers greater than -2.

Visually, if we were to plot the graph of g(x), it would be a V-shaped graph with the vertex at (12, -2) and the arms extending upward infinitely. The function will never be less than -2 since we are subtracting 2 from the absolute value.

Use the combination formula to solve a problem when n = 7 and r = 5.

Answers

Answer:

21 is your answer

Step-by-step explanation:

The combination formula is used to calculate the number of ways to choose r items from a set of n items without regard to order. The formula is:

C(n,r) = n! / (r! * (n-r)!)

where n is the total number of items and r is the number of items to be chosen.

Using this formula, we can solve the problem when n = 7 and r = 5 as follows:

C(7,5) = 7! / (5! * (7-5)!)

= (7 x 6 x 5 x 4 x 3 x 2 x 1) / [(5 x 4 x 3 x 2 x 1) x (2 x 1)]

= (7 x 6) / (2 x 1)

= 21

Therefore, there are 21 ways to choose 5 items from a set of 7 items without regard to order.

Pat found the sum of the first 2021 positive even integers and Ray found the sum of the first 2022 positive even integers. By how much does Ray's sum exceed Pat's sum

Answers

The sum of the first 2021 positive even integers is (2021 x 2022). Therefore, Ray's sum exceeds Pat's sum by 2052.

The sum of the first 2021 positive even integers is given by 2+4+6+...+4040. To find this sum, we can use the formula for the sum of an arithmetic series:

S = (n/2)(a + l)

where S is the sum of the series, n is the number of terms, a is the first term, and l is the last term. In this case, n = 2021, a = 2, and l = 4040 (which is the 2021st even integer). So we have:

S = (2021/2)(2 + 4040)

= 2041210

Therefore, Pat's sum is 2041210.

The sum of the first 2022 positive even integers is given by 2+4+6+...+4042. Using the same formula as above, we have:

S = (2022/2)(2 + 4042)

= 2043262

Therefore, Ray's sum is 2043262.

To find by how much Ray's sum exceeds Pat's sum, we can subtract Pat's sum from Ray's sum:

2043262 - 2041210 = 2052

Find intervals of concavity for f(x) = 3 cos x, with 0 < x < 21. Show your work for full credit.

Answers

The intervals of concavity for f(x) = 3 cos x, with 0 < x < 21, are (0, π/2) and (3π/2, 2π).

To find the intervals of concavity for f(x) = 3 cos x, we need to analyze the second derivative of the function.

First, let's find the second derivative of f(x):

f'(x) = -3 sin x (derivative of cos x)

f''(x) = -3 cos x (derivative of -3 sin x)

Now, we can analyze the concavity of f(x) by considering the sign of the second derivative:

When x ∈ (0, π/2): In this interval, cos x > 0, so f''(x) < 0. The second derivative is negative, indicating concavity downwards.

When x ∈ (π/2, 3π/2): In this interval, cos x < 0, so f''(x) > 0. The second derivative is positive, indicating concavity upwards.

When x ∈ (3π/2, 2π): In this interval, cos x > 0, so f''(x) < 0. The second derivative is negative, indicating concavity downwards.

What is the equation of a line that passes through the points (0,4) and (3,8)?

Answers

Answer:

y = 4/3x + 4

Step-by-step explanation:

The equation is y = mx + b

m = the slope

b = y-intercept

Slope = rise/run or (y2 - y1) / (x2 - x1)

Points (0,4) and (3,8)

We see the y increase by 4 and the x increase by 3, so the slope is

m = 4/3

Y-intercept is located at (0,4)

So, the equation is y = 4/3x + 4

The slope of the line can be found using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0, 4) and (x2, y2) = (3, 8)

slope = (8 - 4) / (3 - 0) = 4/3

Now we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is one of the given points. Choosing (0, 4) as the point, we get:

y - 4 = (4/3)(x - 0)

Simplifying:

y - 4 = (4/3)x

y = 4/3 x + 4

Therefore, the equation of the line is y = 4/3 x + 4.

In November 2014, the Miami Marlins agreed to pay Giancarlo Stanton $325 million over 10 years. If this salary were to be covered by ticket sales only, how many more tickets per game would the Marlins tickets per home game have to sell to cover Stanton's salary in the 81 home games per year if the average ticket price is $75 ? each year

Answers

The Miami Marlins would need to sell approximately 5,350 more tickets per game to cover Giancarlo Stanton's salary if ticket sales were the only source of revenue.

To calculate how many more tickets per game the Marlins would need to sell to cover Giancarlo Stanton's salary, we need to determine the total cost per game and then divide it by the average ticket price.

Total cost per game:

Stanton's salary over 10 years is $325 million. To find the annual cost, we divide this amount by 10: $325 million / 10 = $32.5 million per year. Since there are 81 home games per year, the cost per game is $32.5 million / 81 = $401,234.57 (rounded to the nearest cent).

Number of tickets per game:

To cover the total cost per game, we divide it by the average ticket price. $401,234.57 / $75 = 5,349.80 (rounded to the nearest ticket).

Therefore, the Marlins would need to sell approximately 5,350 more tickets per game to cover Giancarlo Stanton's salary if ticket sales were the sole source of revenue.

3 groups consisting of 4 students.

Mark can't be in the first group.

The combination formula that I used is =  n! / r!(n-r)!

where: n = number of choices ; r = number of people to be chosen.

This is the formula I used because the order is not important and repetition is not allowed.

Since Mark can't be considered in the first group, the value of n would be 11 instead of 12. value of r is 4.

numerator: n! = 11! = 39,916,800

denominator: r!(n-r)! = 4!(11-4)! = 4!*7! = 120,960

Combination = 39,916,800 / 120,960 = 330

Therefore, There are 330 ways that the instructor can choose 4 students for the first group.

b) What is the percent amount that the value changes by each year?

Let's say that the value of a car over time is given by the equation:y = 20,000 (.88)Tell me the following

Answers

Answer:

Step-by-step explanation:

So bascially decay means shrinks or shrivels. Growth means like growing, bigger, sort of like a happy plant :D.

To find if this is getting bigger or is shrinking, lets plug in something simple like 1 for the time(t). Sooo:

20,000*.88^1

Since its a 1 exponent it does nothing so:

20,000*.88

Now this is 17600 you can use calculator but if you do this in head like me all I did is multiply 88 by 2 which was simply since 8 times 2 is 16 so 160+16 is 176 then I added zeros:

y=17600

As we can see this is smaller than 20,000, so it is a decaying problem.

By what percent tho.

Well this is pretty easy to reconize once you understand where to find it.

When they talk about percentage, they mean how much it decreased by.

This is 100%-the multiplyied value.

In this case the multiplyed value is 0.88, sooo:

100%-88%=18%

So the percent amount that the value decreased by is 18%.

To determine the electron domain charge cloud geometry of \(BrF_5\), we need to examine the number of electron domains around the central atom (Br).

\(BrF_5\) consists of one central bromine atom (Br) surrounded by five fluorine atoms (F). Each bond and lone pair of electrons represents an electron domain.

In \(BrF_5\), there are five bonding pairs (Br-F) and no lone pairs around the central bromine atom. Therefore, the total number of electron domains is five.

find the next four terms of the geometric sequence given the a1=2x r=x³

Answers

Answer:   \(2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}\)

===========================================================

Explanation:

The first term is \(a_1 = 2\text{x}\) and the common ratio is \(r = \text{x}^3\)

To get the second term, we multiply the first term by that common ratio

\(a_2 = a_1*r = 2\text{x}*\text{x}^3 = 2\text{x}^4\)

Repeat a similar idea for the third term

\(a_3 = a_2*r = 2\text{x}^4*\text{x}^3 = 2\text{x}^{4+3} = 2\text{x}^7\)

and the fourth term is

\(a_4 = a_3*r = 2\text{x}^7*\text{x}^3 = 2\text{x}^{7+3} = 2\text{x}^{10}\)

The fifth term is

\(a_5 = a_4*r = 2\text{x}^{10}*\text{x}^3 = 2\text{x}^{10+3} = 2\text{x}^{13}\)

Something to notice: The exponents of the first five terms are: 1, 4, 7, 10, 13. The sequence of exponents is arithmetic even though the original underlying sequence is geometric.

The reason why the exponent sequence is arithmetic is because we keep multiplying by \(\text{x}^3\), and hence we keep adding 3 to each exponent to get the next exponent.

-----------------------------------------

To summarize, the first five terms are:

\(2\text{x}, \ 2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}\)

We will ignore the first term 2x since your teacher wanted you to find the next four terms after that first term (i.e. term2 through term5).

The empirical rule may be used to determine the percentage of data values that must be within only one, two, and three standard deviations of the mean for data having a bell-shaped distribution.

The 68 95 99 rule, commonly referred to as the empirical rule in statistics, asserts that given normal distributions, 68% of observed data points will fall within one standard deviation from the mean, 95% will fall between two standard deviations, and 99.7% will happen within three standard deviations.

Fairly anticipate that your data will resemble a normal distribution, the empirical rule, the mean, as well as the standard deviation become even more beneficial. Determine probabilities and percentages for many events just by knowing these two statistics.
