28 is 12 less than k
Answers
the value of k is 40.
to solve for k when 28 is 12 less than k, we set up an equation and then solve it.
Let's denote k as the unknown number. According to the problem, 28 is 12 less than k, which can be written as:
28 = k - 12
To solve for k, we need to isolate k on one side of the equation.
28 = k -12
28 + 12 = k
40 = k
k = 40
So, the value of k is 40.
The complete question is:

Evaluate the expression. 9! − 5!
Answers
Evaluate means just solve it.
9! = 9x8x7x6x5x4x3x2x1 = 362880
5! = 5x4x3x2x1 = 120
362880 - 120 = 362760
There is your answer
This is the product of a number and below it until 1.
In mathematical language
a! = a * (a - 1)!
So,
5! = 5 * 4 * 3 * 2 * 1 = 120
9! = 9 * 8 * 7 * 6 * 5 *4 *3 * 2 *1 = 326 880
Therefore 9! - 5! = 326 880 - 120 = 326 760

B) the first marble is replaced, and another marble is chosen at random. if you're told the marble has the number 6 on it, what is the probability the marble is blue?
Answers
B) 1/2 (there is only 2 marbles with the number 1 on it. So its a 50/50 chance its red.)
Also ivorbigg has no clue what he/she is talking about. A probably never has a value higher than 1. If it did, that would mean that is more than 100% chance of that event happening which is impossible. All of your answers to anything probability related is 1 or less.
The probability that the marble is blue on the second draw, given that the first marble was replaced and had the number 6 on it, is 4 out of 7.
Explanation:The probability that the marble is blue on the second draw, given that the first marble was replaced and had the number 6 on it, can be found using conditional probability.
The probability of drawing a blue marble on the first draw is 4 out of 7 (4 blue marbles out of a total of 7 marbles). Since the first marble was replaced, the probability of drawing a blue marble on the second draw is still 4 out of 7. Therefore, the probability that the marble is blue on the second draw, given that the first marble had the number 6 on it, is also 4 out of 7.
Find the absolute maximum and minimum values of f on the set
d. f(x, y) = 9 + xy − x − 2y, d is the closed triangular region with vertices (1, 0), (5, 0), and (1, 4)
Answers
[tex]\implies\begin{cases}f_x=y-1=0\implies y=1\\f_y=x-2=0\implies x=2\end{cases}[/tex]
which tells you that the only critical point of [tex]f(x,y)[/tex] occurs at (2, 1), which does lie within the region [tex]D[/tex]. At this point, we get [tex]f(2,1)=7[/tex].
Next we check along the boundaries of [tex]D[/tex]. They are the lines [tex]x=1[/tex] with [tex]0\le y\le4[/tex], [tex]y=0[/tex] with [tex]1\le x\le5[/tex], and [tex]y=5-x[/tex] with [tex]1\le x\le5[/tex].
If [tex]x=1[/tex], then [tex]f(1,y)=8-y[/tex], which is monotonically decreasing and must therefore attain its maximum at [tex]y=0[/tex] and minimum at [tex]y=4[/tex]. We get [tex]f(1,0)=8[/tex] and [tex]f(1,4)=4[/tex].
If [tex]y=0[/tex], then [tex]f(x,0)=9-x[/tex], which is also monotonically decreasing and attains its maximum at [tex]x=1[/tex] and minimum at [tex]x=5[/tex]. We get [tex]f(1,0)=8[/tex] and [tex]f(5,0)=4[/tex].
If [tex]y=5-x[/tex], then [tex]f(x,5-x)=g(x)=-x^2+6x-1[/tex]. We have [tex]g'(x)=-2x+6=0\implies x=3[/tex], which suggests an extremum occurs at (3, 2). We get [tex]f(3,2)=8[/tex].
So [tex]f(x,y)[/tex] has a minimum value of 4 at (1, 4) and (5, 0), and a maximum value of 8 at (1, 0) and (3, 2).
For the function f(x, y) = 9 + xy - x - 2y in the triangular region, the maximum value is 9 at point (1,0), and the minimum value is 1 at point (1,4). The critical point does not lie within the triangle region.
Explanation:To find the absolute maximum and minimum values of the multivariate function f(x, y) = 9 + xy − x − 2y on the triangular region with vertices (1, 0), (5, 0), and (1, 4), we first locate the critical points within the region by solving the system of first order partial derivative equations.
∂f/∂x = y - 1 = 0, which means y = 1∂f/∂y = x - 2 = 0, which means x = 2
Notice that (2,1) is not in the triangle region, so there's no critical point in the interior of the triangle. The maximum and minimum must occur somewhere on the boundary, i.e., the lines connecting (1, 0), (5, 0), and (1, 4).
After using these points in the function, we get the following:
F(1,0) = 9F(5,0) = 4F(1,4) = 1
The maximum value is 9 when (x,y) are (1,0) and the minimum value is 1 when (x,y) are (1,4).

What is f(x)=8x2+4x written in vertex form
Answers
using completing the square:
f(x)=8(x^2+1/2x+1/16)-(8*1/16) -->since we added a 1/16 inside the parenthesis, we need to subtract that quantity times 8
f(x)=8(x+1/4)-1/2
Answer:
Vertex form:
[tex]f(x)=8(x+\frac{1}{4})^2-\frac{1}{2}[/tex]
Step-by-step explanation:
Given: [tex]f(x)=8x^2+4x[/tex]
We need to write in vertex form.
Vertex form:
[tex]y=a(x-h)^2+k[/tex]
vertex: (h,k)
[tex]f(x)=8x^2+4x[/tex]
Step 1: Take out 8 common from each term
[tex]f(x)=8(x^2+\frac{1}{2}x)[/tex]
Step 2: Add and subtract square of half of coefficient of x
[tex]f(x)=8(x^2+\frac{1}{2}x+\frac{1}{16}-\frac{1}{16})[/tex]
Step 3: Factor the term inside parentheses
[tex]f(x)=8(x^2+2\cdot \frac{1}{4}\cdot x+(\frac{1}{4})^2)-8\cdot \frac{1}{16})[/tex]
[tex]f(x)=8(x+\frac{1}{4})^2-\frac{1}{2}[/tex] [tex]\because (a^2+2ab+b^2)=(a+b)^2[/tex]
Hence, The vertex form of f(x)

Charlotte's annual salary is 29,354 dollars. She is hoping to win the World Lottery which has a grand prize of 6,156,782,221 dollars. Approximately how many times as large is the World Lottery's grand prize as Charlotte's annual salary?
Answers
The answer is approximately 209,742.53 times as large.
The World Lottery's grand prize is approximately 209,701 times larger than Charlotte's annual salary when dividing the grand prize amount by her annual salary.
To determine approximately how many times larger the World Lottery's grand prize is compared to Charlotte's annual salary, we perform a division of the two amounts. Charlotte's annual salary is $29,354, and the World Lottery grand prize is $6,156,782,221.
To find out how many times larger the lottery prize is than Charlotte's salary, we use the following calculation:
Lottery Prize to Salary Ratio = World Lottery Grand Prize / Charlotte's Annual Salary
Lottery Prize to Salary Ratio = $6,156,782,221 / $29,354 ≈ 209,701
This means that the World Lottery's grand prize is approximately 209,701 times larger than Charlotte's annual salary.
Note: This is a simplified approximation and does not take into account any deductions or taxes that would be applied to either the grand prize or the salary.
Which ordered pair is identified by the letter "G" on this coordinate grid?
Answers
When we say coordinate pair, we usually express our pair in the form of:
(x, y)
This means the point on the x axis is first, and the point on the y is second in the parenthetical format of coordinates. We know that the x coordinate is the horizontal one, while the y is vertical.
If we start with the x axis, we see that our point, G, is just below the number 2. That means our x coordinate is 2. For the y coordinate, we see that the point is directly lined up with the -3, therefore our y coordinate is -3.
Therefore, our coordinates are (2, -3).

A cell phone plan includes 450 anytime minutes for $35 per month, plus $18.85 for a cell phone and $25 for a one-time activation fee. let x represent the number of months of service. write an equation in the form y equals mx plus
b. find the ordered pair associated with the equation for xequals9. if you sign a 1-yr contract, how much will this cell phone package cost?
Answers
The cost of the cell phone plan over x months is represented by the equation y = 35x + 43.85. For 9 months, the total cost is $359.85, and for a 1-year contract, the total annual cost is $463.85.
The total monthly cost of the cell phone plan for x months of service can be represented by the linear equation y = 35x + 18.85 + 25. Here, y represents the total cost, x represents the number of months, 35 is the cost per month, 18.85 is the cost of the cell phone, and 25 is the one-time activation fee. The equation simplifies to y = 35x + 43.85, since the cost of the phone and the activation fee is a one-time charge, independent of the number of months.
For x = 9 months of service, the ordered pair is (9, y), where y = 35(9) + 43.85. Therefore, the ordered pair associated with x = 9 is (9, 359.85).
If you sign a 1-year contract, which is 12 months, you will pay y = 35(12) + 43.85, which results in a total cost of $463.85 for the year.

The salesman has observed that many students are looking for cars that cost less
than $5,000. If he decides to also deal in cars that cost less than $5,000 and projects selling 200 of them over the next 10 years, how will the distribution be affected?
Answers
Introducing vehicles costing less than $5,000 will alter the supply curve by adding a new segment for lower-priced cars, likely leading to an increase in the quantity supplied for this market segment. This reflects market segmentation and aligns with the demand for cheaper vehicles.
The introduction of cars less than $5,000 into the salesman's inventory may affect the distribution of car sales. When discussing economic models, a supply curve (such as curve So) indicates the quantity of goods that sellers are willing to supply at various prices. According to the scenario provided, Point J on the supply curve So shows that if the price is $20,000, the quantity supplied will be 18 million cars. However, if the price drops to below $5,000, this will most likely introduce a new segment on the supply curve, as the current supply data relates to higher-priced vehicles.
Introducing lower-cost cars will attract a different consumer base, often overlooked in premium markets. This could lead to an increase in the quantity supplied of cheaper cars, as the demand for this segment is likely to be different from premium cars. If the projection of selling 200 cars in 10 years holds true, it will introduce a new point on the supply curve, which will represent cars at a lower price point and possibly a higher quantity compared to the original supply curve for higher-priced cars.
It cannot be determined from the given information whether the overall effect will pull market equilibrium towards the lower end, but it introduces the concept of market segmentation where different products and prices can co-exist, catering to different consumer needs and preferences.
