Write a function in any form that would match the graph shown below:
Answers
The function that would match the graph shown below is given as follows:
y = -5(x³ + 7x² + 8x - 16).
How to define the function?The function is defined using the Factor Theorem, as we have the x-intercepts of the graph, hence we can write the function as a product of it's linear factors.
Considering the x-intercepts, the roots are given as follows:
x = -4 with a multiplicity of 2, as the graph turns.x = 1 with a multiplicity of 1.Hence, considering the leading coefficient a, the function is defined as follows:
y = a(x + 4)²(x - 1)
y = a(x² + 8x + 16)(x - 1)
y = a(x³ + 7x² + 8x - 16).
When x = 0, y = 80, hence the leading coefficient a is obtained as follows:
-16a = 80
a = -5.
Hence the function is:
y = -5(x³ + 7x² + 8x - 16).

You want to determine the number of solutions to three different systems of equations.
Standard formA linear equation is written in standard form when the coefficients are mutually prime, and the leading coefficient is positive:
ax +by = c . . . . . . GCF(a, b, c) = 1, a > 0
The equations are easiest to compare when they are all written in standard form.
Numbers of solutionsA system will have an infinite number of solutions when the equations are identical.
A system will have zero solutions when it reduces to ...
(non-zero constant) = 0
A system will have one solution when the equations are different.
System 1A factor of 2 can be removed from the first equation:
2x -3y = 5
A factor of 3 can be removed from the second equation:
2x -3y = 5
These equations are identical, so have infinitely many solutions.
System 2Multiplying the first equation by 2 gives ...
2y = -3x +6
Adding 3x, we have ...
3x +2y = 6
When we subtract the second equation from this, we get ...
(3x +2y) -(3x +2y) = (6) -(3)
0 = 3
These equations have no solution.
System 3These equations are already in standard form, and are different. This system has one solution.

The correct answer is option B. That is the amount of plastic needed for making one plastic cylinder is 57 cm²
What is a cylinder?A cylinder is a three-dimensional geometric shape that has two congruent circular bases that lie parallel to each other and are connected by a curved surface. It can be thought of as a stack of circles or as a prism with a curved surface. Some common examples of cylinders include soda cans, water bottles, and pipes.
Given that the individual container of bubbles will be a plastic cylindrical tube with a diameter 2 cm and a height of 8 cm.
So radius = diameter/2 = 2/2 = 1 cm.
The surface area of the cylinder = 2πrh + 2πr²
SA = 2π × 1 ×8 + 2π × 1²
SA = 2π + 16π
SA = 18π
Substituting the value of π = [tex]\frac{22}{7}[/tex]

You work independently as a copier salesperson. Last month, you sold 26 printers at a cost of $1,750 each. The cost of goods sold for each printer is $975. Additional operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month). Use this information to calculate (a) your gross profit and (b) your net income.
Answers
To calculate the gross profit, we need to subtract the cost of goods sold (COGS) from the revenue generated by sales. The revenue generated by sales can be found by multiplying the number of printers sold by the selling price of each printer, which is $1,750.
Revenue generated by sales = 26 x $1,750 = $45,500
The cost of goods sold for each printer is $975, so the total cost of goods sold for all 26 printers is:
Total cost of goods sold = 26 x $975 = $25,350
Therefore, the gross profit can be calculated as:
Gross profit = Revenue generated by sales - Total cost of goods sold
Gross profit = $45,500 - $25,350
Gross profit = $20,150
The gross profit is $20,150.
To calculate the net income, we need to subtract all operating expenses from the gross profit. The operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month).
Total operating expenses = $3,000 + $50 + $550
Total operating expenses = $3,600
Therefore, the net income can be calculated as:
Net income = Gross profit - Total operating expenses
Net income = $20,150 - $3,600
Net income = $16,550
The net income is $16,550.
In summary, the gross profit is the revenue generated by sales minus the cost of goods sold, which in this case is $20,150. The net income is the gross profit minus all operating expenses, which in this case is $16,550.

The graph shows an upward parabola with vertex (minus 2, minus 6) and passes through (minus 5, 7), (minus 4, 0), (0, 0), and (1, 7)
Answers
The graph that represents the equation is:
The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).
Option B is the correct answer.
We have,
The equation y = (3/2)x² - 6x represents an upward parabola since the coefficient of x² is positive.
Now,
The vertex of the parabola.
x = -b/2a,
where a and b are the coefficients of x² and x, respectively.
So,
a = 3/2 and b = -6
x = -(-6)/(2(3/2)) = 6/3 = 2.
Plugging x = 2 into the equation,
We get y = 3/2(2)² - 6(2) = -6,
so the vertex is (2, -6).
We can eliminate options A and C since their vertices are not (2, -6).
Now,
To check which of the remaining options fits the equation, we can plug in the given points and see if they satisfy the equation.
Option B gives:
When x = -1, y = 3/2(-1)² - 6(-1) = 7
When x = 0, y = 3/2(0)² - 6(0) = 0
When x = 4, y = 3/2(4)² - 6(4) = 0
When x = 5, y = 3/2(5)² - 6(5) = 7.5
So option B fits the equation, and is the graph that represents
y = (3/2)x² - 6x.
Therefore,
The graph that represents the equation is:
The graph shows an upward parabola with vertex (2, -6) and passes through (-1, 7), (0, 0), (4, 0), and (5, 7).

On Team B 80% of the football players weigh more than 200 pounds. If 41 men are on the team, how many weigh more than 200 pounds?
Answers
Team B has 33 players that weigh more than 200 pounds.
How to calculate the percentage?To calculate the percentage, divide the amount by the total value and multiply the result by 100. The percentage is calculated using the formula: (value/total value)100%.
When 80% of the players weigh more than 200 pounds, 20% of the players weigh less than 200 pounds.
We can start by locating 20% of the players:
20% of 41 = 0.20 x 41 = 8.2
So we can guess that there are about 8 players weighing 200 pounds or fewer.
We may subtract this estimate from the total number of participants to obtain the number of players who weigh more than 200 pounds:
41 - 8 = 33
As a result, Team B has 33 players that weigh more than 200 pounds.

Answers
After filling Container B completely, there are approximately 209.56 cubic feet of water left in Container A.
How to solveContainer A:
Diameter = 14 feet
Radius = Diameter / 2 = 14 / 2 = 7 feet
Height = 11 feet
Volume of Container A = π * (7^2) * 11 ≈ 1,696.46 cubic feet
Container B:
Diameter = 10 feet

Aisha and Malik are making fruit salads for a picnic. Aisha mixes 4 cups of melon and 1 cup of apple and Malik mixes 13 cups of melon and 3 cups of apple. Use Aisha and Malik’s percent of melon to determine whose fruit salad will taste more melony.
Answers
Answer:
Maliks fruit salad will taste more melony
Step-by-step explanation:
To determine whose fruit salad will taste more "melony," we can calculate the percentage of melon in each fruit salad for Aisha and Malik.
For Aisha's fruit salad:
Total cups of fruit = 4 cups of melon + 1 cup of apple = 5 cups
Percentage of melon = (4 cups of melon / 5 cups of total fruit) x 100%
For Malik's fruit salad:
Total cups of fruit = 13 cups of melon + 3 cups of apple = 16 cups
Percentage of melon = (13 cups of melon / 16 cups of total fruit) x 100%
Now we can calculate the percentages:
Aisha's percentage of melon:
(4 cups of melon / 5 cups of total fruit) x 100% = 80%
Malik's percentage of melon:
(13 cups of melon / 16 cups of total fruit) x 100% ≈ 81.25%
Based on the calculations, Malik's fruit salad has a higher percentage of melon (81.25%) compared to Aisha's fruit salad (80%). Therefore, Malik's fruit salad is likely to taste more "melony" compared to Aisha's fruit salad.

Round your answers to the nearest integer.
Answers
The sample mean for the number of years worked is 12.9, and 35% of the employees in the sample worked for the company for at least 10 years.
To find the sample mean, we need to add up all the years worked and divide by the total number of employees:
8 + 13 + 15 + 3 + 13 + 28 + 4 + 12 + 4 + 26 + 29 + 3 + 10 + 3 + 17 + 13 + 15 + 15 + 23 + 13 = 258
So, the sample mean is 258/20 = 12.9 (rounded to the nearest tenth).
To find the percentage of employees who worked for at least 10 years, we need to count the number of employees who worked for 10 years or more.
From the data, we see that 7 employees worked for at least 10 years (Employee Number: 2, 3, 5, 10, 11, 15, and 19). So, 7 out of 20 employees worked for at least 10 years, which is 35%. Therefore, the answer is 35% (rounded to the nearest integer).

Answers
Answer:
Both solutions are valid, and depending on the context of the problem, one or both solutions may be useful in solving for different parameters, such as the maximum height or the time of flight of the projectile.
Step-by-step explanation:
In a projectile motion formula, such as the one that describes the height of an object in motion as a function of time, there are two solutions because the object can reach the same height at two different times during its trajectory.
The negative solution represents the time it takes for the object to reach its maximum height and then start falling back down to the ground. The positive solution represents the time it takes for the object to reach the same height on its way up.
So, both solutions are valid, and depending on the context of the problem, one or both solutions may be useful in solving for different parameters, such as the maximum height or the time of flight of the projectile.

Answers
The periodic deposit required to reach the financial goal of $1,000,000 in 45 years with a 6.75% annual interest rate compounded monthly is approximately $541.05.
And, Amount $292,593.00 comes from deposits and $707,407.00 comes from interest.
For the periodic deposit, we can use the formula:
P = (FV × r) / ((1 + r)ⁿ - 1)
where P is the periodic deposit, FV is the financial goal, r is the interest rate per period, and n is the total number of periods.
Using the given values, we get:
P = ($1,000,000 0.0675) / ((1 + 0.0675/12)^(45x12) - 1)
P ≈ $541.05
So, the periodic deposit required to reach the financial goal of $1,000,000 in 45 years with a 6.75% annual interest rate compounded monthly is approximately $541.05.
And, To determine how much of the financial goal comes from deposits and how much comes from interest, we can calculate the total amount of deposits made over the 45-year period:
Hence, Total deposits is,
P n = $541.05 (45 x 12)
≈ $292,593.00
Then we can subtract this amount from the financial goal to get the amount that comes from interest:
Amount from interest = FV - Total deposits
= $1,000,000 - $292,593.00
≈ $707,407.00
So , Amount $292,593.00 comes from deposits and $707,407.00 comes from interest.

Suppose a truck rental costs $20 plus $0.30 for each mile
driven. If your total cost of a rental was $39. 80, how many miles
did you drive?
Answers
If the total cost is $39.80, then the number of miles driven is 66 miles.
If your total cost of a rental was $39. 80, how many miles did you drive?Here we know that a truck rental costs $20 plus $0.30 for each mile driven.
Then we can model this with a linear equation where the y-intercept is 20, and the slope is 0.30 (where the independent variable will be the number of miles driven).
Then the total cost is modeled by the linear equation:
y = 20 + 0.3*x
If the total cost is $39.80, then we can solve:
39.8 = 20 + 0.3*x
39.8 - 20 = 0.3*x
19.8/0.3 = x
66 =x
There are 66 miles.

What is a translation?In Mathematics and Geometry, the translation a geometric figure or graph to the right simply means adding a digit to the value on the x-coordinate of the pre-image while the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.
Since the parent function is f(x) = |x|, g(x) would be created by translating f(x) the parent function one units to the right and one units downward as follows;
f(x) = |x|
g(x) = |x - 1| - 1

Describe Algebra?Algebra is a branch of mathematics that deals with the study of mathematical symbols and their manipulation. It involves the use of letters, symbols, and equations to represent and solve mathematical problems.
In algebra, we use letters and symbols to represent unknown quantities and then use mathematical operations such as addition, subtraction, multiplication, division, and exponentiation to manipulate those quantities and solve equations. We can use algebra to model and solve real-world problems in various fields such as science, engineering, economics, and finance.
Some common topics in algebra include:
Solving equations and inequalities
Simplifying expressions
Factoring and expanding expressions
Graphing linear and quadratic functions
Using logarithms and exponents
Working with matrices and determinants
First, we need to convert the length of the mural from feet to inches to match the unit of the sections.
20 feet x 12 inches/foot = 240 inches
Then, we need to determine the number of sections in the mural:
240 inches / 8 inches/section = 30 sections
Now, we can find the total time it will take Ms. Estrada to complete the mural:
30 sections x 50 minutes/section = 1500 minutes
Finally, we can convert the time to hours:
1500 minutes / 60 minutes/hour = 25 hours
Therefore, it will take Ms. Estrada about 25 hours to complete the mural.
