Answers:
right 1, down 3 (these two answers only)
Step-by-step explanation:
There are two transformations going on. The first of which is the horizontal or x translation (aka shifting) where the 'x' turns into 'x-1'. This moves the xy axis 1 spot to the left, giving the illusion that the graph moves 1 unit to the right.
The "-3" at the end shifts the graph down 3 units. If g(x) = f(x) - 3, then g(x) is the output of f(x) but 3 less than that, which is why it shifts down 3 units.
The function g(x) represents two transformations from its parent function f(x) = 1/x: a horizontal shift to the right by 1 unit and a vertical shift down by 3 units.
Explanation:When comparing the graph of the function g(x) = (1)/(x-1) - 3 with its parent function f(x) = 1/x, the transformations undergone by g(x) include:
The addition of -1 inside the parentheses with the independent variable x, which shifts the graph to the right by 1 unit.The subtraction of 3 from the entire expression, which translates the graph down by 3 units.These transformations can be understood with the help of given examples. For instance, adding or subtracting a number to/from the independent variable x, like f(x+1), results in a horizontal shift of the graph. Multiplying the independent variable by a number, say 2 as in f(2x), would cause a horizontal compression of the graph. In our case, since the function g(x) includes x-1, it is indicating a horizontal shift to the right, and since the -3 is subtracted from the entire function, it denotes a vertical shift downward.
Which equation is a point slope form equation for line AB ? y+1=2/3(x−4) y+1=3/2(x−4) y+1=−2/3(x−4) y+1=−3/2(x−4) A graph with a line running through point A, with coordinates (4, -1), and point B, with coordinates (-2, 3)
Answer:
C) y + 1 = -2/3(x - 4)
Step-by-step explanation:
The given line passes through the points A (4, -1) and B (-2, 3)
Let's find the slope now.
Slope (m) = (y2 - y1)/(x2 - x1)
= (3 - (-1)) / (-2 - 4)
= (3 + 1)/-6
= 4/-6
Slope (m) = -2/3
The equation of line y - y1 = m (x - x1)
y - (-1) = -2/3(x - 4)
y + 1 = -2/3(x - 4)
Answer: C) y + 1 = -2/3(x - 4)

Your school is planning a field trip to the zoo. There are two different bus companies that the school can use. Bus company A has a $25 rental fee of plus $4 for each student. Bus company B has a $115 rental fee plus $2 for each student. How many students will need to go in order for the bus to cost the same from both companies? a) 42 students b)73 students c)70 students d)45 students
Answer:
D. 45 students
25+4n=115+2n
-2n -2n
25+2n=115
-25 -25
2n=90
2n/2=90/2
n=45
The cost for both bus companies A and B is equal when there are 45 students on the trip. This result is achieved by setting the cost equations of the two companies equal to each other and solving for the number of students.
Explanation:To solve this problem, we set the cost equations for bus companies A and B equal to each other and solve for the number of students.
For company A, the cost is $25 (rental fee) + $4 per student. For company B, the cost is $115 (rental fee) + $2 per student.
So, the equation becomes: $25 + $4 * number of students = $115 + $2 * number of students.
If you rearrange that equation and solve for the student variable by subtracting $2 * students from both sides and subtracting $25 from both sides, you end up with $2 * students = $90.
This means that the number of students, when divided by $90 and $2, is equal to 45. Thus, 45 is the number of students for the bus cost from both companies to be equal. Therefore, the answer is (d) 45 students.

A nutrition label states that there are 36g of carbohydrates in each serving. This accounts for 12% of a daily value. How many grams of carbohydrates are recommended per day?
The recommended daily intake of carbohydrates is 300 grams per day based on a daily value of 12%.
To determine how many grams of carbohydrates are recommended per day based on a daily value of 12%, you can use the following calculation:
First, calculate what 1% of the daily value would be:
1% of daily value = 36 grams / 12% = 3 grams
Now, to find the recommended daily intake, simply multiply this by 100 since you want to find the recommended intake for 100% of the daily value:
Recommended daily intake = 3 grams/1% * 100% = 300 grams
So, the recommended daily intake of carbohydrates is 300 grams per day based on a daily value of 12%.

Write the explicit formula for the geometric sequence.
64, 32, 16, 8, ...
A) an = 8 · 4n-1
B) an = 8 · 2n-1
C) an = 32 · 0.5n-1
D) an = 64 · 0.5n-1
Which answer?
Answer:
Option D is correct.
Explicit formula for the geometric sequence is, [tex]a_n = 64 \cdot (0.5)^{n-1}[/tex]
Step-by-step explanation:
Geometric sequence states that a sequence of numbers in which the ratio between consecutive terms is constant,
we can write a formula for the nth geometric sequence in the form of:
[tex]a_n = a_1r^{n-1}[/tex] .....[1] where [tex]a_1[/tex] is the first term and r is the common ratio between successive term.
Given the sequence: 64, 32, 16 , 8......
Here, first term ([tex]a_1[/tex]) = 64.
Common ratio(r) = 0.5
Since,
[tex]\frac{32}{64} =0.5[/tex]
[tex]\frac{16}{32} = 0.5[/tex] ,
[tex]\frac{8}{16} = 0.5[/tex] ......
Substitute the value of a and r in [1] we get;
[tex]a_n = 64 \cdot (0.5)^{n-1}[/tex]
therefore, the explicit formula for the geometric sequence is, [tex]a_n = 64 \cdot (0.5)^{n-1}[/tex]
What is the absolute value of point D? A.-6 B.9 C.7 D.-7
The absolute value of a number is its distance from zero on the number line, which is always positive or zero. If point D is -7, its absolute value would be 7, matching option D in the given choices.
Explanation:The absolute value of a number is the distance of that number from zero on the number line, regardless of direction. Therefore, it is always a positive value or zero. In this case, whether point D is -6, 9, 7, or -7, the absolute value would be the positive counterpart of that number.
To find the absolute value of point D, we look for the option that falls in line with the definition of absolute value. For option A (-6), the absolute value is 6; for option B (9), the absolute value remains 9; for option C (7), the absolute value remains 7; and for option D (-7), the absolute value is 7.
Thus, considering point D is given a negative value in the question, the correct answer for the absolute value of point D is 7, which corresponds to choice C if the value of D is 7 or D if the value of D is -7.

Unable to determine the subject of the question due to lack of information.
Explanation:The arithmetic operations described pertain to the addition and multiplication of numbers and the result of their signs. For instance:
When two positive numbers add or multiply, the result is also positive (e.g., 3 + 2 = 5 and 2 x 3 = 6).
When two negative numbers add or multiply, the result is negative when adding and positive when multiplying (e.g., -4 + (-2) = -6 and (-4) x (-3) = 12).
For numbers with opposite signs, in addition, subtract the smaller number from the larger number and give the result the sign of the larger number, while in multiplication, the result will have a negative sign (e.g., -5 + 3 = -2 and (-3) x 2 = -6).
Regarding quantum numbers, the sets of quantum numbers provide information about the state of an electron in an atom. Each set of numbers must follow specific rules:
The principal quantum number n must be a positive integer.
The azimuthal quantum number l must be an integer ranging from 0 up to n - 1.
The magnetic quantum number mē must range from -l to +l.
The spin quantum number ms must be either +1/2 or -1/2.
Therefore, for the given quantum numbers a. {4, 2, -2, 1} is not an allowed set because the spin quantum number must be either +1/2 or -1/2, not 1. Similarly, set b. {3, 1, 0, -1/2} is a possible set because it follows all the designated rules for quantum numbers.
an advertiser will pay you $12 for every 100 viewers you have watching the show. based on the information above , how much will they give you?
Answer:
$17,600,000
Step-by-step explanation:
First, we need to count the amount of money we pay for each episode. If each episode costs you $200,000 to make, that would be subtracted from your total amount. If there are 150,000 viewers per episode, we can multiply 150,000 by 11, because there are 11 episodes. There are 1,650,000 people watching your show! Since the advertiser pays you $12 per person, we can simply multiply 12 times the number of people. You have earned $19800000. However, we need to subtract how much it took us to make the episodes, so we multiply the number of episodes, 11, by $200,000 and subtract the product from our total amount. Your amount of profit is $17,600,000.

what is the mass of aluminum?
Answer:
The mass of aluminum is 26.982 g/mol.
Step-by-step explanation:
The molar mass of an element is the mass in grams of 1 mole of the element. It is determined by taking the atomic weight of the element on the periodic table, and writing it as g/mol.
The mass of aluminum will depend on the quantity and context. Given quantities in chemical compounds range from 26.98g in AlPO4 to 80.94g in Al2S3 (for 1 mol). For specific quantities or other situations, the mass should be calculated proportionally.
Explanation:The mass of aluminum can be determined using the specific heat and molecular absorption principles. A known quantity of aluminum in a compound like AlPO4 contains 1.000 mol or 26.98 g Al, while an Al2Cl6 molecule contains 1.994 mol or 53.74 g Al. When considering an Al2S3 molecule, it contains 3.00 mol or 80.94 g Al, which is the greatest mass of Al among the examples.
To calculate the mass for a different quantity of aluminum, you need to adjust these figures proportionally. For instance, if you have only half a mol of Al2S3, the mass would not be 80.94g, but half of that. Also, regarding mass of atoms, it is often represented in atomic mass units (amu) or in kilograms.
These examples give a clear idea of how to determine the mass of aluminum in different situations. The specific condition determines which calculation or table to use.

Answer:
the desired equation is y = (1/6)x + 3/2.
Step-by-step explanation:
From the graph you can see immediately that the y-intercept is (0,3/2).
This is "b" in y = mx + b.
Focus on point (-3,1). Substitute -3 for x in y = mx + 3/2 and then 1 for y:
1 = m(-3) + 3/2
Clear this result of fractions by mult. all three terms by 2:
2 = m(-6) + 3. Solving for m, -6m = 2 - 3, or -6m = -1. Then m = 1/6, and the
desired equation is y = (1/6)x + 3/2.
Solve the system of equations using the substitution method. y = 7x – 16, y = 2(2x – 5) What is the solution? (, )
Answer:
Solving the system of equations using the substitution method, the solution is: x=2 and y=-2
Step-by-step explanation:
(1) y=7x-16
(2) y=2(2x-5)
Substituting "y" of the equation (1) in the equation (2)
(2) 7x-16=2(2x-5)
Applying the distributive property to eliminate the parentheses on the right side of the equation:
7x-16=2(2x)-2(5)
Multiplying:
7x-16=4x-10
Solving for x: Subtracting 4x and adding 16 both sides of the equation:
7x-16-4x+16=4x-10-4x+16
3x=6
Adding like terms:
Dividing by 3 both sides of the equation:
3x/3=6/3
x=2

The error in the given ratio table is that the values in the "total" row are not calculated correctly based on the provided "miles" and "gallon" values.
The values in the "total" row do not match the sum of the "miles" and "gallon" values for each corresponding column.
When miles = 0 and gallons = 0, the total should also be 0.
When miles = 10 and gallons = 2, the total should be 12.
When miles = 20 and gallons = 4, the total should be 24.
When miles = 30 and gallons = 6, the total should be 36.
When miles = 40 and gallons = 8, the total should be 48 (not 49).
When miles = 50 and gallons = 10, the total should be 60.
The error occurs in the row where miles = 40 and gallons = 8. The "total" value is listed as 49 instead of the correct value, which should be 48. So, the error in the table is that the "total" value for miles = 40 and gallons = 8 is incorrect.
