Did you figure out a problem and you are celebrating?
What steps would you need to take to graph the function:
f(x)=-3x^3-6x^2+3x+6
Name any x-intercepts and y-intercepts in the graph of the function.
Describe the end behavior of the function.
For extra credit, draw a sketch of the function by hand or in Paint.
The x-intercepts in the graph are ( - 2, 0 ), ( 1, 0 ) and ( - 1, 0 ) and the y-intercepts of the graph is ( 0, 6). The graph of the function tends to infinity in the negative y-axis direction after intersecting the x-axis at ( 1, 0).
Consider the function,
f(x) = - 3x³ - 6x² + 3x + 6
To find the x-intercept of the function we substitute y = 0.
f(x) = y = - 3x³ - 6x² + 3x + 6
- 3x³ - 6x² + 3x + 6 = 0
3x³ + 6x² - 3x - 6 = 0
3x²( x + 2 ) - 3 ( x - 2) = 0
( x + 2 )( 3x² - 3) = 0
Therefore,
x = - 2 and;
3x² - 3 = 0
3x² = 3
x = ± 1
Hence, the x-intercepts are ( - 2, 0 ), ( 1, 0 ) and ( - 1, 0 ).
Now, the y-intercept will be when x = 0,
y = - 3x³ - 6x² + 3x + 6
y = - 3(0)³ - 6(0)² + 3(0) + 6
y = 6
Hence, the y-intercept is ( 0, 6).
The graph of the function intersects the x-axis at ( - 2, 0) and ( - 1, 0 ) and then intersects the y-axis at ( 0, 6) then after intersecting the x-axis at ( 1, 0 ) the graph tends to infinity in the negative x-axis direction.

One of the members of staff from the software organisation travels to Birmingham on a business trip. She pays for her ticket with three crisp £25 notes at the ticket office and is given £10.50 in change. Assuming that she bought a return ticket and that each leg of the journey cost the same amount, how much was one leg of the journey?
The cost of the one leg of the journey is 32.25 pounds.
Given that:-
Number of 25 pounds notes given by the member of staff travelling to Birmingham = 3
Change given to her = 10.50 pounds
It is assumed that she bought the return ticket as well and that each leg of the journey cost the same amount.
We have to find the cost of one leg of the journey.
Let the cost of one leg of the journey be x pounds.
Hence, we can write,
2x + 10.50 = 25*3
2x + 10.50 = 75
2x = 75 -10.50
2x = 64.50
x = 64.50/2
x = 32.25 pounds.
Hence, the cost of one leg of the journey is 32.25 pounds.

A party planner organized a dinner party. The party planner recorded the height of the candlesticks over time and graphed the relationship.
graph with the x axis labeled time in hours and the y axis labeled height of candlestick in inches and a line going from the point 0 comma 9 through the point 2 comma 6
Find and interpret the slope and y-intercept in this real-world situation.
The slope is negative two thirds, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases two thirds of an inch every hour.
The slope is negative three halves, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases three halves of an inch every hour.
The slope is 9, and the y-intercept is negative two thirds. The candle starts at a height of two thirds of an inch and decreases 9 inches every hour.
The slope is 9, and the y-intercept is negative three halves. The candle starts at a height of three halves of an inch and decreases 9 inches every hour.
The Slope of the line is 3/2 and the y-intercept is at (0,3)
Each solution in the two-variable scenario can be thought of as the Cartesian coordinates of a specific point on the Euclidean plane.
Each line in the Euclidean plane that is defined by a solution to a linear equation can be thought of as the sum of all solutions to a linear model with two variables.This is how equations in this class came to be referred to be "linear." A hyperplane of size n in Euclidean space is made up of all the solutions to an equation system with integer variables (a subdomain of dimension n1).The usage of linear equations is widespread throughout all fields of mathematics, physics, and engineering because they can commonly properly represent non-linear systems.The graph of the line passes through (0,9) and (2,6) .
Slope of the line = (6-9)÷(2-0) = 3/2
Hence the line will have the equation:
y - 6 = 3/2 ( x - 2 )
or, 2y - 12 = 3x - 6
or, 2y - 3x = 6
Now from the real world situation at y = 0, x = - 2
and at x = 0, y = 3
Hence the y-intercept is at (0,3)

In a relation, the input is the number of people and the output is the number
of backpacks.
Is this relation a function? Why or why not?
A. No, because you do not know how many people there are.
B. No, because the same number of people might have a different
number of backpacks.
C. Yes, because each person has one backpack.
D. Yes, because a given number of people always has the same
number of backpacks.
If input is number of people and output is number of backpack then it is not a relation because same person can have different number of backpacks.
When the input is the number of people an the output is the number of backpacks, it is not a relation,
The reason is, Because same number of people might have a different number of backpacks.
A function is a relation in which each and every input has an output, and each and every input has a unique output.
In this situation, it is not compulsory that each person carry a backpack.

A yoga studio charges a $140 yearly fee for membership plus $15 for each class. What is the average total cost per class if a studio member takes 50 classes per year?
The Average total cost per class if a studio member takes 50 classes per year will be 17.8$
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
Average = Sum of observations/the number of observations
Given that A yoga studio charges a $140 yearly fee for membership plus 15 dollars for each class.
Yearly charge = 140 $
Charge per class = 15 $
The Number of classes attended by; studio members per year = is 50
We want to find the average total cost per class for this member for a year.
The Total charge = Yearly charge + Number of classes attended x Charge per class
Total charge = 140 + 50 x 15
Total charge = 140 + 750
Total charge = 890$
Than the Average total cost per class =890/ 50

Considering the given systems of equations, the expressions to obtain the desired results are filled as follows:
No solution: -2x + 5 + 11x = 9x + 6. (11 and 6 fill the blanks). One solution: -2x + 5 + 8x = 9x + 6. (8 and 6 fill the blanks). Infinitely many solutions: -2x + 5 + 11x = 9x + 5. (11 and 5 fill the blanks). When does a system of equations has no solution?A system of equations will have no solution if it can be written in the following format:
0x = constant different of 0.
Hence:
-2x + 5 + 11x = 9x + 6(the final number can be any number different of 5)
As:
9x + 5 = 9x + 6
0x = 1 -> division by 0 does not exist, hence no solution.
When does a system of equations has one solution?A system of equations will have one solution if it can be written in the following format:
cx = d, c different of 0.
Hence:
-2x + 5 + 8x = 9x + 6(the final number on the left side can be any number different of 11)
6x + 5 = 9x + 6
-3x = 1
x = -1/3 (lone solution).
When does a system of equations has infinitely many solutions?A system of equations will have infinitely many solutions if it can be written in the following format:
0x = 0.
Hence:
-2x + 5 + 11x = 9x + 5
9x + 5 = 9x + 5
0x = 0 (0/0 results in any value).

[tex]\begin{gathered} A+\Delta A=\pi(r+\Delta r)^2 \\ =\pi(r^2+2r\Delta r+\Delta r^2) \end{gathered}[/tex]We can neglect the term Δr^2 since we are assuming that Δr is a very small quantity. Then:
[tex]A+\Delta A=\pi r^2+2\pi r\Delta r[/tex]Substitute A=πr^2 and isolate Δr from the equation:
[tex]\begin{gathered} \Rightarrow\pi r^2+\Delta A=\pi r^2+2\pi r\Delta r \\ \Rightarrow\Delta A=2\pi r\Delta r \\ \Rightarrow\Delta r=\frac{\Delta A}{2\pi r} \end{gathered}[/tex]Assuming that the ideal area of the disk is 1000in^2, calculate the ideal radius of the disk:

Answer:

Step-by-step explanation:
the sales of laptops makes 5% of his sales, so you can estimate his total sales of a month if you know his sales of laptops of the same month. This is done by multiplying the amount of sales of laptops that month, x, by 20. You do this because 5% x 20 = 100%.
