What is the domain of the following graph?
Answer:
D
Step-by-step explanation:
Look at the graph and find the lowest x value and the highest x value. We don't use y in the inequality because it is not a range question. Domain relates to x-values and range relates to y-values.
When you have found the lowest and highest x-values, look at their dots. If it is shaded, then the answer would contain a less than sign between the number and variable. If it shaded, then it would contain a less than or equal to sign.
Both of the dots with the lowest and highest values are shaded. And the lowest and highest values are -4 and 4 respectively.
Therefore, the answer is D.
If the length of a rectangle prism is doubled, it’s width is tripled, and it’s height remains the same, what is the volume of the new rectangle prism?
If in a rectangular-prism, the length is doubled, width is tripled and height is same, then the volume of new rectangular prism will be 6 times the original-prism.
The "Volume" of a 3-D object is defined as the amount of space that object occupies in three-dimensional space. It is a measure of the total capacity or size of the object
Volume of a rectangular prism is ⇒ Volume = Length × Width × Height,
If the length of the rectangular prism is doubled, the new length would be 2 times the original length.
If the width is tripled, the new width would be 3 times the original width, and
If the height remains the same, it would be the same as the original height.
Let the original length be = "L", width be = "W", and height be = "H",
So, New Length = 2L , New Width = 3W, New Height = H (remains unchanged),
So, volume of new rectangular prism is :
⇒ New Volume = (New Length)×(New Width)×(New Height),
⇒ (2L) × (3W) × H
⇒ 6LWH
Therefore, volume of "new-rectangular prism' is 6 times volume of original rectangular prism.

It wants you to multiply (5) x (8) = 40/3
72° (x+4)° Write an equation that can be used to find the value of x.
Answer:
In a triangle, the sum of the interior angles is 180 degrees. So, we can set up the following equation:
72° + (x+4)° + A = 180°
where A is the measure of the third angle in the triangle.
Simplifying the equation, we get:
(x+4)° + 72° + A = 180°
x + 76° + A = 180°
Subtracting 76° from both sides, we get:
x + A = 104°
Therefore, an equation that can be used to find the value of x is x + A = 104°, where A is the measure of the third angle in the triangle. Note that we do not have enough information to solve for x or A individually, but we can use this equation to relate the two angles in the triangle.
Baron Blakk decided to start saving. He deposited seven thousand kroner at the start of each year. He always received a fixed interest rate of 2.3%. How much interest had he received in total after eight years? Give the answer to two decimal places.
The amount of interest that Baron Blakk would receive in total after eight years would be 6, 118. 03 krona
How to find the interest ?To find the interest that Baron Blakk received in eight years of savings, we first need to find the future value of the savings. We can do this with the Future value of annuity due formula as this is an annuity and it is an Annuity due as it is paid at the beginning of the year.
The total value after eight years is:
= Amount saved x ( Future value of annuity, interest, number of years)

on tuesday, a local gas station had 135 135135 customers. the table above summarizes whether or not the customers on tuesday purchased gasoline, a beverage, both, or neither. based on the data in the table, what is the probability that a gas station customer selected at random on that day did not purchase gasoline?
The probability that a randomly selected gas station customer on that day did not purchase gasoline is 10/27.
We know that, the probability of any event is the ratio of the number of favorable case to that event to the total number of cases.
The total number of customers in that Gas Station on that day = 135
According to the data table,
Number of customers did not purchase gas but purchased beverage = 35
Number of customers neither purchase gas nor beverage = 15
So total number of customers did not purchase gas = 35 + 15 = 50
Here number of favorable cases = 50
So the probability that a randomly selected gas station customer on that day did not purchase gasoline = 50/135 = 10/27.

A toy manufacturer produces its toys according to the production function: (10 PTS) Q = 4K + 5L where Q = output of toys per hour K = capital input per hour L = labor input per hour Answer the following questions. YOU MUST SHOW YOUR WORK TO RECEIVE CREDIT. a) If K = 20, how much L is needed to produce 400 toys per hour? b) If L = 40, how much K is needed to produce 500 toys per hour?
a) To find out how much L is needed to produce 400 toys per hour when K is equal to 20, we can use the production function formula provided, which is Q = 4K + 5L.
To solve for L, we can rearrange the formula as follows: Q - 4K = 5L 400 - 4(20) = 5L 320 = 5L L = 64
Therefore, to produce 400 toys per hour with K = 20, the manufacturer would need 64 units of labor input per hour.
b) Similarly, to find out how much K is needed to produce 500 toys per hour when L is equal to 40, we can use the production function formula: Q = 4K + 5L
Substituting the given values, we get: 500 = 4K + 5(40) 500 = 4K + 200 4K = 300 K = 75
Therefore, to produce 500 toys per hour with L = 40, the manufacturer would need 75 units of capital input per hour.
In conclusion, the production function formula provides a useful tool for toy manufacturers to produce a desired level of output. By manipulating the formula, the manufacturer can also calculate the maximum output possible given a certain combination of inputs.

To rewrite the equation of the circle in graphing form, we need to complete the square for both the x and y terms.
x² + 6x + y² - 4y = -9
Step 1: Move the constant term to the right side of the equation.
x² + 6x + y² - 4y + 9 = 0
Step 2: Group the x terms and the y terms separately.
(x² + 6x) + (y² - 4y) + 9 = 0
Step 3: Complete the square for the x terms. To do this, take half of the coefficient of x (which is 6), square it, and add and subtract it inside the parentheses.
(x² + 6x + 9 - 9) + (y² - 4y) + 9 = 0
(x + 3)² - 9 + (y² - 4y) + 9 = 0
(x + 3)² + (y² - 4y) = 0
Step 4: Complete the square for the y terms. To do this, take half of the coefficient of y (which is -4), square it, and add and subtract it inside the parentheses.
(x + 3)² + (y² - 4y + 4 - 4) = 0
(x + 3)² + (y - 2)² - 4 = 0
Step 5: Move the constant term to the right side of the equation.
(x + 3)² + (y - 2)² = 4
The equation is now in graphing form, which is:
(x - h)² + (y - k)² = r²
where (h, k) is the center of the circle and r is the radius.
Comparing the equation to the graphing form, we see that the center of the circle is (-3, 2) and the radius is 2. Thus, the graph of the circle is centered at (-3, 2) with a radius of 2.

Terry has a new retirement account. He plans to make deposits of $4,750 per year for the next 40 years. He expects the account to earn 9.1% for the first 25 years, 6.9% for the next ten years, and then 4.5% for the last five years. How much will have have at the end of the forty years based on these assumptions?
With an initial investment of $19,675.13 and yearly deposits of $3,000 at an interest rate of 9.25%, the account will be worth around $336,312.91 in 25 years.
what is unitary method ?The unitary approach is a strategy for problem-solving in which the value of one piece of a quantity is determined, then the cost of an unique number of units associated with that quantity is subsequently determined using that value. In other words, it's a method of proportional used to resolve issues where one unit's value is known but another's value is needed. The unitary method's fundamental premise is to establish a percentage between two quantities, one of which is stated in the form of one unit and the other in terms of a greater number of units.
given
In the following ten years, we have:
P = $4,750 r = 6.9% = 0.069
n = 10
[tex]FV2 = $4,750 * ((1 + 0.069)^10 - 1) / 0.069[/tex]
= $74,894.87
In the previous five years, we have:
P = $4,750
r = 4.5% = 0.045
n = 5
= $127,756.44
Lastly, we can combine the two figures to determine the account's entire future value:
FV is $208,556.47 + $127,756.44 = $336,312.91 (annual deposits + initial investment).
With an initial investment of $19,675.13 and yearly deposits of $3,000 at an interest rate of 9.25%, the account will be worth around $336,312.91 in 25 years.

The Udderly Delicious Cheese Factory produces 200 blocks of cheddar cheese and 200 blocks of Swiss cheese each day. The factory uses 5 quarts of milk to make a block of cheddar cheese and 6 quarts of milk to make a block of Swiss cheese. How many total gallons of milk does the factory use each day?
Therefore , the solution of the given problem of ratio comes out to be the Udderly Delicious Cheese Factory needs 550 gallons of milk in total.
What is a ratio?A group comprising values both variable "a" and "" that seem to be equal is found using the straightforward formula "a / b," whenever "b" might be a greater number than zero. A ratio is created by combining two ratios. The ratio , fraction could have been 1:1 if there were just one guy and three women. There are 1/4 men and 3/4 women in the group.
Here,
For cheddar cheese, multiply the quantity of blocks by 200 and the amount of milk consumed by each block by 5.
200 blocks of cheddar cheese divided by 5 quarts per block equals a total of 1000 quarts.
For Swiss cheese, the formula is as follows: 200 blocks of Swiss cheese, or 6 quarts of milk per block.
200 blocks of Swiss cheese divided by 6 quarts per block equals 1200 quarts of milk in total.
Total milk used equals the sum of the milk required to make cheddar cheese and the milk used to make Swiss cheese, or 1000 quarts plus 1200 quarts, or 2200 quarts.
We can convert quarts to gallons by dividing by 4 because there are 4 quarts in a gallon.
= 1000 quarts + 1200 quarts
= 2200 quarts
We can convert quarts to gallons by dividing by 4 because there are 4 quarts in a gallon.
=> Total gallons of milk used = 2200 quarts / 4 quarts/gallon = 550 gallons
Thus, to make 200 blocks of cheddar cheese and 200 blocks of Swiss cheese each day,
the Udderly Delicious Cheese Factory needs 550 gallons of milk in total.

On Friday, there is an 80% chance of snow. On Saturday, there is a 7 out of 9 chance that it will snow. On Sunday, there is a 75
14% chance that it is going to snow. Which day has the least chance that it will snow?
Answer: There is an approximate 10.7% probability that it will snow on Sunday, making it the day with the lowest likelihood of snow.
Step-by-step explanation: Snow is highly likely on Friday with an 80% probability. The likelihood of no snowfall occurring on Friday is 20%, which can be calculated by subtracting 0.8 (or 80%) from 1.
There is a high probability of snowfall on Saturday with a 7 in 9 likelihood. In simpler terms, the probability can be reduced to 7 out of 9 or around 0.78. The likelihood of snowfall on Saturday is 78%, therefore the chance of no snow on that day is 22% which is equivalent to 1 minus 0.78.
There is a high likelihood of snow on Sunday with a probability of 75 out of 100 or 14 out of 19. It is possible to reduce this to a likelihood of 0.7514, or about 0.107. The likelihood of Sunday not having snow is equivalent to subtracting 0.107 from 1, resulting in a 0.893 or 89.3% probability.
Two friends live 7 miles apart. One Saturday, the two friends set out on their bikes at 8am and started riding towards each other. One rides at 0. 2 miles per minute, and the other rides at 0. 15 miles per minute. At what time will the two friends meet?
The time when the two friends will meet is 8:20 am.
We can start by finding the combined speed at which the two friends are approaching each other. This can be found by adding their individual speeds:
0.2 miles/minute + 0.15 miles/minute = 0.35 miles/minute
This means that the friends are approaching each other at a combined speed of 0.35 miles/minute.
To find out how long it will take for the friends to meet, we can use the formula:
time = distance / speed
In this case, the distance is 7 miles (since they are 7 miles apart) and the combined speed is 0.35 miles/minute. So we can solve for time as follows:
time = 7 miles / 0.35 miles/minute = 20 minutes
Therefore, it will take the two friends 20 minutes to meet each other while biking towards each other.
Since they started biking at 8am and it took them 20 minutes to meet, they will meet at 8:20am.

What is limf(x) where f(x) is as shown in the table
As x approaches 2 from both sides, the values of f(x) do not approach a single value, and f(x) does not have a limit. The answer is option (d).
What is limit of a function?The calculus concept known as the limit of a function describes how a function behaves when the input variable approaches a particular value.
The phrase "lim f(x) as x approaches a" (or "limit of a function f(x) as x approaches a") describes what occurs to the output of the function when x approaches a value without actually reaching a.
The limit can be expressed in terms of two-sided, left-sided, or right-sided limits, depending on whether x approaches a from both sides, the left, or the right.
We must look at the values of f(x) as x approaches 2 in order to determine lim f(x) as x approaches 2.
Looking at the table, we can see that the values of f(x) rise from 3.99 to 4 as x approaches 2 from the left (that is, as x approaches 2 while remaining smaller than 2). The values of f(x) decline from -5 to -5.01 as x moves towards 2 from the right (that is, as x approaches 2 but staysgreater than 2).
The limit of f(x) as x approaches 2 does not exist because the values of f(x) do not approach a single integer as x approaches 2 from both sides.

Consider the queueing model of the bank in Conceptual Problem 6.9. Suppose the arrival rate is 18 per hour, the mean service time is 10 minutes, and the lobby can handle 15 customers at one time. How many tellers should be used if the aim is to keep the mean queueing time to less than 5 minutes
The number of tellers that should be used if the aim is to keep the mean queuing time to less than 5 minutes is 3.
To determine the number of tellers follow these steps:
1. Arrival rate (λ) = 18 customers per hour
2. Mean service time (μ) = 10 minutes per customer = 1/6 customer per minute
3. Lobby capacity = 15 customers
4. Target mean queuing time = 5 minutes
Now, calculate the service rate and find the number of tellers needed to achieve the target mean queueing time.
Step 1: Convert arrival rate to customers per minute: λ = 18/60 = 0.3 customers per minute
Step 2: Calculate the service rate per teller: 1/μ = 1/(1/6) = 6 customers per hour = 0.1 customers per minute
Step 3: Determine the number of tellers (n) needed to achieve the target queuing time:
Using the formula:
n > λ / (μ * (Wq_target + 1/μ))
Here, Wq_target is the target mean queuing time in minutes.
n > 0.3 / (0.1 * (5/60 + 1/(6/60)))
After solving the inequality, we get:
n > 2.4
Since the number of tellers must be a whole number, therefore, at least 3 tellers should be used in the queueing model of the bank to keep the mean queueing time to less than 5 minutes.

A game is played by spinning the two spinners
shown. Players match the results of the
spinners to combinations on their game cards.
How many different combinations are possible?
There are 36 different combinations possible when spinning the two spinners in the game, obtained by multiplying the number of outcomes on each spinner (6 × 6 = 36).
What is combination?A combination is a way of selecting a group of items from a larger set without regard to the order, often represented as unordered arrangements of objects, used in mathematics, statistics, and various fields of science.
According to the given information:
To determine the total number of different combinations possible in the game, we need to multiply the number of outcomes on each spinner. The first spinner has six equally likely outcomes (1, 2, 3, 4, 5, or 6), and the second spinner also has six equally likely outcomes (A, B, C, D, E, or F). Therefore, the total number of different combinations possible is:
6 (number of outcomes on the first spinner) × 6 (number of outcomes on the second spinner) = 36
So, there are 36 different possible combinations that can be obtained from spinning the two spinners. These combinations can be used to match with the combinations on the players' game cards and determine the winner of the game.

Answer:
(d) 3 × [A2] + [A1] ⇒ [B1]
(c) -2 × [B1] + [B2] ⇒ [C2]
Step-by-step explanation:
Given three systems of equations, you want to know the operations that transform one system to the next.
A to BEquation B2 is unchanged from equation A2, eliminating choices B and C.
Equation B1 is not a simple multiple of equation A1, eliminating choice A.
Knowing the answer is choice D, we need to find the multiplier k of equation A2 that is being added to A1. We can find that using the x-coefficients:
k(-3) +5 = -4
-3k = -9 . . . . . subtract 5
k = 3 . . . . . . . divide by -3
Then we have ...
3 × [A2] + [A1] ⇒ [B1] . . . . . . . choice D
B to CUsing the same tactics as above, we see that [C1] is unchanged from [B1], eliminating choices A and D.
[C2] is not a simple multiple of [B2], eliminating choice B.
Using the y-coefficient to find k, we have ...
k(1) +2 = 0
k = -2 . . . . . . . . subtract 2
Then we have ...
-2 × [B1] + [B2] ⇒ [C2] . . . . . . . . choice C

Additional comment
We found the equation multiplier, which we called "k", by looking at an arbitrary variable coefficient. Which of the numbers we use in this process is immaterial. That is, we could use either coefficient, or the right-side constant, and we would get the same result.

The correct statements for the triangles are given as follows:
<Z is a right angle.The length of the hypotenuse of triangle STU is a² + b².The longest side of triangle XYZ is XY.What is the Pythagorean Theorem?The Pythagorean Theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
The theorem is expressed as follows:
c² = a² + b².
In which:
c is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.The Pythagorean Theorem holds true for triangle XYZ, hence:
<Z is a right angle -> as the Pythagorean Theorem is true.The longest side of triangle XYZ is XY -> hypotenuse.For triangle STU, the symbol shows that it a right triangle, hence the hypotenuse length is obtained as follows:
a² + b².
Which is equals to the hypotenuse length of XYZ.
