Answer:
Graph 2.
Step-by-step explanation:
When you replace x with x - h, the functions shifts horizontally h units.
Here you are replacing x with x + 4. To write x + 4 in the x - h form, you must write x - (-4) making h = -4. f(x + 4) has a shift of -4 units, or 4 units to the left, compared to f(x).
The function f(x) = x^3 included point (0, 0). It goes up to the right of (0, 0), and down tot eh left of (0, 0).
The answer is graph 2. which shows a shift of 4 units to the left compared with the graph of f(x) = x^3.

Describe a sequence of transformations that transforms the graph of the parent function f into the graph of the function g.
f(x)= x
g(x)= -3(x-4)+1
Answers
Step-by-step explanation:
Parent function f(x) = x
g(x)= -3(x-4) + 1
If any number added or subtracted with x then graph moves left or right
Here 4 is subtracted from x, so graph move 4 units to the right
If any number added or subtracted at the end then graph move up or down
Here 1 is added at the end, so graph move 1 unit up.
g(x) = -f(x), for negative sign the graph reflects across x axis
We have negative sign at first, so the graph reflects over x axis
The graph of [tex]\( g(x) \)[/tex] is the result of these transformations applied to the graph of the parent function [tex]\( f(x) \)[/tex].
The sequence of transformations that transforms the graph of the parent function [tex]\( f(x) = x \)[/tex] into the graph of the function [tex]\( g(x) = -3(x-4)+1 \)[/tex] involves a reflection across the x-axis, a horizontal shift, a vertical stretch, and a vertical shift.
1. Reflection across the x-axis: The negative sign in front of the function[tex]\( g(x) \)[/tex]indicates a reflection across the x-axis. This means that for every point \( (x, y) \) on the graph of [tex]\( f(x) \)[/tex], there will be a corresponding point [tex]\( (x, -y) \)[/tex] on the graph of [tex]\( g(x) \)[/tex].
2. Horizontal shift: The expression [tex]\( (x-4) \)[/tex] inside the function [tex]\( g(x) \)[/tex]indicates a horizontal shift to the right by 4 units. This means that every point on the graph of [tex]\( f(x) \)[/tex] is moved 4 units to the right along the x-axis to get the graph of [tex]\( g(x) \).[/tex]
3. Vertical stretch: The coefficient 3 in [tex]\( -3(x-4) \)[/tex] indicates a vertical stretch by a factor of 3. This means that for every point [tex]\( (x, y) \)[/tex] on the graph of the reflected function[tex]\( -f(x) \)[/tex], the y-coordinate is multiplied by 3 to get the corresponding point [tex]\( (x, 3y) \)[/tex] on the graph of [tex]\( g(x) \)[/tex].
4. Vertical shift: Finally, the[tex]\( +1 \)[/tex] at the end of the function [tex]\( g(x) \)[/tex]indicates a vertical shift upwards by 1 unit. This means that every point on the graph of [tex]\( -3f(x-4) \)[/tex] is moved 1 unit up along the y-axis to get the graph of [tex]\( g(x) \).[/tex]
Putting it all together, the sequence of transformations is as follows:
- Start with the parent function [tex]\( f(x) = x \).[/tex]
- Reflect the graph across the x-axis to get [tex]\( -f(x) \).[/tex]
- Shift the graph 4 units to the right to get [tex]\( -f(x-4) \).[/tex]
- Stretch the graph vertically by a factor of 3 to get [tex]\( -3f(x-4) \).[/tex]
- Shift the graph 1 unit upwards to get [tex]\( -3f(x-4) + 1 \),[/tex] which is the function [tex]\( g(x) \)[/tex].
Therefore, the graph of [tex]\( g(x) \)[/tex] is the result of these transformations applied to the graph of the parent function [tex]\( f(x) \)[/tex].

Answers
Answer:
0.45
Step-by-step explanation:
Ok so you start with -0.9. You need to find how much it will change in an hour and 30 minutes. So you subtract -0.9 from -0.9 and you'd get 0. Now, we have to subtract half of -0.9 (because 30 minutes is half an hour). Half of -0.9 is -0.45. Subtract 0 by -0.45 and you get 0.45.
Answer:
It varies 0,45. For 1,35 - 0,9 = 0,45

The gasoline tank in Deborahs car holds 13.2 gallons. When her gas gauge says that the tank is 1/4 full, how many gallons of gasoline does the tank have?
Answers
Answer:
3.3
Step-by-step explanation:
To find the amount of gasoline when Deborah's tank is 1/4 full, divide the tank's full capacity (13.2 gallons) by 4, which results in 3.3 gallons of gasoline in the tank at 1/4 full.
To find out how many gallons of gasoline Deborah's car has when the tank is 1/4 full, we need to calculate 1/4 of the total capacity of the tank. Since the tank holds 13.2 gallons when full, the amount of gasoline at 1/4 full is calculated as follows:
Divide the full tank capacity by 4 to find 1/4 of the tank's capacity: 13.2 gallons / 4 = 3.3 gallons.Therefore, when Deborah's gas gauge indicates that the tank is 1/4 full, it contains 3.3 gallons of gasoline.

A 20-foot ramp is used at the loading dock of a factory.lf the base of the ramp is placed 19 feet from the base of the dock,how high is the loading dock?
Answers
Answer:
6.24 feet (to nearest hundredth)
Step-by-step explanation:
Use the Pythagoras Theorem:-
20^2 = x^2 + 19^2 where x = height of the loading dock.
x^2 = 20^2 - 19^2 = 39
x = √39
= 6.2449 feet
The height of the loading dock is found to be approximately 6.24 feet.
To solve this problem, we will use the Pythagorean theorem, which is applicable when we have a right triangle. The theorem states:
a² + b² = c²
Here:
a is the height of the loading dock (which we need to find).
b is the base of the ramp (19 feet).
c is the length of the ramp (20 feet).
We can set up the equation as follows:
a² + 19² = 20²
a² + 361 = 400
a² = 39
a = √39 ≈ 6.24 feet
Thus, the height of the loading dock is approximately 6.24 feet.

write down an expression for the nth term of the following sequence, 7, 16, 25, 34, 43
Answers
Answer:9n-2
Step-by-step explanation:
1st = 9*1-2= 7
2nd = 9*2-2= 16
3rd = 9*3-2= 25
4th = 9*4-2 = 34
...
The nth term of the sequence 7, 16, 25, 34, 43, which is an arithmetic sequence with a common difference of 9, is given by the expression 9n - 2.
The sequence given is 7, 16, 25, 34, 43. To find the nth term expression of this sequence, first, we can observe the pattern that each term increases by 9. Therefore, the sequence is an arithmetic sequence. We can use the formula for the nth term of an arithmetic sequence, which is [tex]a_n = a_1 + (n - 1)d[/tex], where [tex]a_1[/tex] is the first term and d is the common difference.
The first term a1 is 7, and the common difference d is 9. So, the nth term is:
[tex]a_n = 7 + (n - 1) \times9[/tex]
To simplify, it will be:
[tex]a_n = 7 + 9n - 9a_n = 9n - 2[/tex]. This is the expression for the nth term of the given sequence.
Given the ordered pairs A (-6, 4) and B(8, 9). Show all work!

b. Find the equation of the line parallel to line AB and passes through the point (14, -6).
c. Find the equation of the line perpendicular to line AB and passes through the point (-5, -10).
Answers
Answer:
Step-by-step explanation:
Two points A and B are given
Using two point formula for straight lines we get
[tex]\frac{x+6}{8+6} =\frac{y-4}{9-4} \\5(x+6) = 14(y-4)\\5x+30 = 14y-56\\5x-14y+86 =0[/tex]
b) A line parallel to AB would be of the form
5x-14y +k=0
Since the line passes through (14,-6) substitute to get k
5(14)-14(-6)+k=0 Or k = -154
Line is 5x-14y-154 =0
c) A line perpendicular to AB would have form as
14x+5y =k1
Substitute (-5,-10) to get k
14(-5)+5(-10) =k1
Or k1 = -120
Hence equation is 14x+5y = -120

Add 28 to both sides
4x = 0.3x + 2.71 + 28
Simplify 0.3x + 2.71 + 28 to 0.3x + 30.71
4x = 0.3x + 30.71
Subtract 0.3x from both sides
4x - 0.3x = 30.71

As the first step, he decided to solve for y in the second equation because it had the smallest number as a coefficient. Max told him that there was a more efficient way. What reason can Max give for his statement?
The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.
The variable x in the second equation has a coefficient of 7 so it will be easy to divide 7 by 7.
The variable y in the second equation has a coefficient of 2 so it will be easy to divide the entire equation by 2.
The variable x in the second equation has the largest coefficient. When dividing by 7, the solution will be a smaller number.

A school district transported a total of 409 students and teachers to a zoo in buses and vans.
-Each bus transported a total of 55 students and teachers.
-Each van transported a total of 12 students and teachers.
-There were 5 buses than vans
What is the total number of students and teachers who rode to the zoo in buses? What is the total number of students as teachers who rode to the zoo in vans?
( 18 points guaranteed)
Answers
Answer: There are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.
Step-by-step explanation:
Since we have given that
Total number of students and teachers = 409
Let the number of vans be x
Let the number of buses be x+5
Number of students and teachers each bus transported = 55
Number of students and teachers each van transported = 12
According to question,
[tex]55(x+5)+12x=409\\\\55x+275+12x=409\\\\67x=409-275\\\\67x=134\\\\x=\frac{134}{67}\\\\x=2[/tex]
Total number of students and teachers who rode to the zoo in buses will be
[tex]55(x+5)\\\\=55(2+5)\\\\=55\times 7\\\\=385[/tex]
Total number of students and teachers who rode to the zoo in vans will be
[tex]12x\\\\=12\times 2=24[/tex]
Hence, there are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.
To find the total number of students and teachers who rode to the zoo in buses, we need to determine the number of buses and multiply it by the number of students and teachers each bus transported. Each bus transported 55 students and teachers, while each van transported 12. By solving the equation using the given information, we can find the total number of students and teachers in each type of vehicle.
Explanation:To find the total number of students and teachers who rode to the zoo in buses, we need to determine the number of buses and multiply it by the number of students and teachers each bus transported.
Let x be the number of vans.
Since there were 5 buses more than vans, the number of buses can be represented as x + 5.
Each bus transports 55 students and teachers, so the total number of students and teachers in buses is (x + 5) * 55.
Each van transports 12 students and teachers, so the total number of students and teachers in vans is x * 12.
Since there were a total of 409 students and teachers, we can create an equation: (x + 5) * 55 + x * 12 = 409.
Solving this equation will give us the value of x, which represents the number of vans. Once we know x, we can calculate the total number of students and teachers who rode to the zoo in buses and vans.
