A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm, which quadratic equation best models the volume of the box?

V = lwh
P = 2(l + w)

Answers

Answer 1

Answer: V(x) = -5x^2 + 70x

Step-by-step explanation:

Let the length and width of the rectangular base be represented by x and y, respectively.

Since the perimeter of the rectangular base is 28 cm, we have:

2x + 2y = 28

x + y = 14

The height of the box is given as 5 cm.

The volume of the box is given by:

V = lwh = xy(5)

V = 5xy

We can solve for y in terms of x from the equation x + y = 14:

y = 14 - x

Substituting this into the equation for the volume, we get:

V = 5x(14 - x)

Simplifying:

V = 70x - 5x^2

The probability that a student chosen at random did not get a B 0.283 The probability of a student not getting a B is the number of students who did not get a B divided by the total number of students.

What does outcome mean?

Outcome can be an event, such as the sum of two dice, or it can be a variable, such as the number of heads from a coin toss.

In this case, there are 21 students who did not get a B (2 male A's, 19 female A's, and 10 female C's), compared to a total of 74 students. Therefore, the probability that a student chosen at random did not get a B

= 21/74

= 0.283

To calculate this probability, we used the total number of students who did not get a B (21) divided by the total number of students (74).

This gives us the probability that a student chosen at random did not get a B.

In addition to using this method to find the probability of a student not getting a B, we can also find the probability of a student getting a B by subtracting the probability of not getting a B from 1.

In this case, the probability of getting a B would be

1 - (21/74)

= 0.71622.

This method can be used to calculate the probability of any outcome given the probabilities of all other outcomes.

use compensation to add or subtract the following (a) 468+59. (b)458-49. (c) 499+599+699. d 10000- 599​

Answers

Answer: A = 527

Step-by-step explanation:

468+59 = 468+(1+58)=(468+1)+58=527

The given addition and subtraction can be done using compensation as follows.

What is Compensation?

Compensation is the method of adding or subtracting numbers by making the numbers easier.

(a) 468 + 59

We add 1 to 59 and make it 60, which make it easier to add.

468 + 60 = 528

Subtract the added 1.

528 - 1 = 527

(b) 458 - 49

Subtract 1 and make 49 to 50

458 - 50 = 408

Add 1 and we get, 408 + 1 = 409

(c) 499 + 599 + 699

Add 3 adding one to each, we get,

500 + 600 + 700 = 1800

Subtracting 3, 1800 - 3 = 1797

(d) 10000 - 599

Adding 1, 10000 + 600 = 9400

Subtracting the before added 1, 9400 - 1 = 9399

The height in inches of a candle that has been burning for x hours is represented by the equation h=12−x . What is the meaning of the y-intercept in the context of the burning candle?

Answers

the y-intercept of the equation h=12−x represents the initial height of the candle when it is first lit, which is 12 inches in this case.

How to solve the question ?

In the given equation, h represents the height of the candle in inches and x represents the number of hours for which the candle has been burning.

The y-intercept of the equation is the point where the graph of the equation intersects the y-axis, which occurs when x is equal to 0. Substituting x=0 in the equation, we get:

h=12-0

h=12

Therefore, the y-intercept of the equation is 12, which means that when the candle is first lit (x=0), its height is 12 inches.

In the context of the burning candle, the y-intercept represents the initial height of the candle before it starts to burn. This is the height of the candle when it is first lit and before any wax has melted. As the candle burns and wax melts, the height of the candle decreases, and this is represented by the negative slope of the equation.

In summary, the y-intercept of the equation h=12−x represents the initial height of the candle when it is first lit, which is 12 inches in this case.

Solving Systems of Linear Equations
Performance Assessment

You are the student council member responsible for planning a school dinner dance. You will
need to choose a caterer, hire a band, analyze costs, and choose flowers for decoration. You
need to keep the ticket price as low as possible and still cover the costs.

Part 1 Choosing a Band

Band A charges a flat fee of $500 to play for the evening.
Band B charges $350 plus $1.50 per student.

Part A: Write a system of equations to represent the cost of the two bands.
Part B: Graph the system of equations and find the number of students for which the cost of
the bands would be equal.

Part 2: Choosing a Caterer

A caterer charges a fixed amount for preparing a dinner plus a rate per student served. The
total cost is modeled by the equation:
Total cost = fixed amount + rate * number of students
You know that the total cost for 50 students will be $450 and the total cost for 150 students
will be $1050. Find the caterer's fixed cost and the rate per student served. Explain your
answer.

Part 3: Analyzing cost

What are linear equations?

The first-degree equations are linear equations. The straight line's equation can be found here. ax+by+c=0 is the most common form of a linear equation, where a and b are zeros.

Part 1:

Let x be the number of students.

Band A: Cost = $500

Band B: Cost $350 +$1.50x

The system of equations representing the cost of the two bands is:

CostA = 500

CostB = 350+ 1.5x

Part 2:

Let F be the fixed cost and R be the rate per student served.

From the given information, we can write two equations:

50R + F = 450

150R + F = 1050

Subtracting the first equation from the second, we

get:

100R = 600

Therefore, R = 6.

Substituting R in the first equation, we get:

50(6)+F450

Therefore, F = 150.

So, the caterer's fixed cost is $150 and the rate per student served is $6.

Part 3:

For 100 students:

CostA 500

CostB = 350+ 1.5(100) 500

Both bands have the same cost, but Band A has a lower variable cost.

So, we should choose Band A.

Total cost for 100 students = 500 + 150+ 6(100) =

$1250

Cost per ticket = Total cost / Number of students = 1250/100 = $12.50

For 200 students:

CostA = 500

CostB = 350+ 1.5(200) = 650

Band A still has a lower cost, so we should choose Band A.

Total cost for 200 students 500+ 150 + 6(200) = $1850

Cost per ticket = Total cost / Number of students =

1850/200 $9.25

Part 4:

Let D be the number of bouquets of daisies and R be the number of bouquets of roses.

The cost of daisies is $25 per bouquet and the cost of roses is $35 per bouquet. We want to spend no more than $500, so we can write:

25D +35R < 500

If we buy 15 bouquets of daisies, then we can spend at most $425 on roses:

25(15) + 35Rs 500

375 +35R ≤ 500

35R ≤ 125

If we buy 15 bouquets of daisies, then we can.

Mathematics College spend at most $425 on roses:

25(15)+35R ≤ 500

375 +35R≤ 500

35R ≤ 125

R≤ 3.57

So, we can buy at most 3 bouquets of roses.

Describe function ?

In mathematics, a function is a rule that assigns a unique output or value to each input or element in a given set. It is a mathematical object that describes how one quantity (the output) depends on another quantity (the input).

A function can be represented by a graph, a table, or an algebraic equation. The input values are usually denoted by the variable x, while the output values are denoted by the variable y, f(x), or some other symbol. The notation f(x) is read as "f of x" and is used to represent the output value of the function when the input value is x.

A function can be defined in various ways:

Geometrically, by specifying a curve or surface in the plane or in space.

Algebraically, by specifying a formula or equation that gives the output in terms of the input.

Numerically, by specifying a table of input-output pairs.

Verbally, by giving a description of how the output depends on the input.

Find the value of tan 2α if tanβ= 5/12 and sinα= 3/5

Answers

The value of tan2[tex]\alpha[/tex] = 6/7  where tan[tex]\beta[/tex] = 5/12 and sin[tex]\alpha[/tex] = 3/5.

What are the trigonometric identities are used to solve?

Trigonometric identities allow us to formulate tan 2[tex]\alpha[/tex] in terms of tan[tex]\beta[/tex] and sin[tex]\alpha[/tex] as follows:

[tex]tan 2\alpha = \frac{ 2 tan \alpha }{1 - tan² \alpha }[/tex]

We know sin[tex]\alpha[/tex], so we can use the Pythagorean identity to find cos[tex]\alpha[/tex]

cos² [tex]\alpha[/tex] + sin² [tex]\alpha[/tex] = 1

cos² [tex]\alpha[/tex] = 1 - sin² [tex]\alpha[/tex] = 1 - ([tex]\frac{3}{5}[/tex])² = [tex]\frac{16}{25}[/tex]

cos α = ±[tex]\sqrt{\frac{16}{25} }[/tex]= ±[tex]\frac{4}{5}[/tex]

sin[tex]\alpha[/tex] and tan[tex]\beta[/tex] are both in the first or third quadrants because they are both positive numbers. Since cos[tex]\alpha[/tex] is positive, we can use the following positive root:

cos α = [tex]\frac{4}{5}[/tex]

Now we can use the tangent identity to find tan α:

tan [tex]\alpha[/tex] = [tex]\frac{sin\alpha }{cos\alpha }[/tex]=[tex]\frac{\frac{3}{5} }{\frac{4}{5} }[/tex]= [tex]\frac{3}{4}[/tex]

Next, we can use the Pythagorean identity to find tan² [tex]\alpha[/tex]:

tan² [tex]\alpha[/tex] + 1 = sec² [tex]\alpha[/tex]

tan² [tex]\alpha[/tex] = sec² [tex]\alpha[/tex] - 1

sec [tex]\alpha[/tex] = 1/cos [tex]\alpha[/tex] = 5/4

tan² [tex]\alpha[/tex] = (5/4)² - 1 = 9/16

Now we can use the formula for tan 2[tex]\alpha[/tex]:

tan 2[tex]\alpha[/tex] = 2 tan α / (1 - tan² α)

tan 2[tex]\alpha[/tex] = 2(3/4) / (1 - 9/16)

tan 2[tex]\alpha[/tex]= 6/7

Therefore, tan 2[tex]\alpha[/tex] is equal to 6/7.

A circle is a two-dimensional shape that is defined as a set of all points in a plane that are equidistant from a fixed point called the center. The distance between the center and any point on the circle is called the radius, which is a constant value for all points on the circle.

A circle can be represented by its center point and radius or by its diameter, which is the distance across the circle passing through its center. Circles have several important properties, such as their circumference (the distance around the outside of the circle), their area (the amount of space enclosed by the circle), and their diameter (the longest distance across the circle).

Circles are used in many areas of mathematics, physics, engineering, and other sciences. They are also used in everyday life, such as in the design of round objects like wheels and in the creation of circular patterns in art and architecture.

Solve for x. x+8|=-2

Answers

Answer:

To solve for x in the equation x+8|=-2, we first need to isolate the absolute value expression on the left side of the equation. We can start by subtracting 8 from both sides: x + 8 | = -2 x + 8 - 8 | = -2 - 8 x | = -10 Now we can solve for x by considering the two cases for the absolute value: 1. x + 8 = -10 2. -(x + 8) = -10 Solving for x in each case, we get: 1. x = -18 2. x = 2 Therefore, the solutions for x are -18 and 2.

2x + 5y = 4
2x - y = -8

Answers

We get x = -3 and y = 2 on solving 2x + 5y = 4; 2x - y = -8

Let's find y from the second equation in terms of x:

2x - y = -8

-y = -2x - 8

y = 2x + 8

Now, we may enter the following expression in place of y in the first equation:

2x + 5y = 4

2x + 5(2x + 8) = 4

Simplifying this equation, we get:

12x + 40 = 4

Subtracting 40 from both sides, we get:

12x = -36

Dividing both sides by 12, we get:

x = -3

Now we can substitute this value of x into our expression for y:

y = 2x + 8 = 2(-3) + 8 = 2

Hence, x= -3 and y= 2 are the answers to the system of equations.

The complete question can be:

2x + 5y = 4

2x - y = -8

solve for x and y

Find the equation of a line perpendicular to y = -6 that contains the point (1, 3). Write the equation in slope-intercept form.

Answers

The equation of a line perpendicular to y = -6 that contains the point (1, 3) is x = 1 .

Evaluating equation in slope-intercept form :

We are given a line that runs through the point (1, 3) and is perpendicular to y = -6.

We want to write the equation for this line in slope-intercept form.

                           Slope-intercept form is y=mx+b,

where m is the slope and b is the value of y at the y intercept, hence the name. First, we need to find the slope (m) of the line.

               

                              Given line = y = -6

                            y = 0x - 6

compare with  y  = mx + C

therefore slope m = 0

the slope of the perpendicular line can be given as

M perpendicular = -1/m

M perpendicular = - 1/0

Keep in mind that we were given the line's perpendic subsequently, to find the slant of this line, we can do the accompanying condition

                                         0m=1

Partition the two sides by 0

                                                m = 1/0

This  is indistinct - subsequently, the line has a vague slant . If so, then, at that point, it implies the line is an upward line

An upward line is composed as

                                               x=k,

where k is the worth of x at the x side . The slope-intercept form cannot be used to write it.

                                   Substituting  1 for k

y- y₁ = m perpendicular - ( x- x₁)

y - 3 = - 1/0( x - x₁ )

0  = - ( x- 1 )

x-1 = 0

x = 1

because this value is the same as the value of x at every point along such a line; in this instance, as indicated by the point (1, 3), this value is 1.

Hence, the equation of a line perpendicular to y = -6 that contains point 1,3 is x = 1 .

d) Total Compoundings = 21

Compound interest:

Compound interest is the concept of adding interest to the principal amount of a loan or investment and then calculating the interest for the next period based on the new total.

This means that the interest earned or charged on an investment or loan is not only depends on the principal amount and the interest rate but also on the time period and the frequency of compounding.

Here we have

18% compounded every 4 months for 7 years

a) The annual interest rate as decimal = 18% = 18/100 = 0.18

b) Number of compoundings = 12/4  = 3

Step-by-step explanation:

enter an equation for which the solution is the daily room charge, in dollars per day, when a person stays at the hotel for 3 day and is charged a total of $234.

Answers

Using equations, the daily room charge, in dollars per day, is $78 per day.

What are Equations?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let x be the daily room charge, in dollars per day.

Then the total charge for staying for 3 days is 3x dollars.

According to the problem statement, the total charge for staying for 3 days is $234. So we can set up the equation:

3x = 234

To solve for x, we can divide both sides by 3:

[tex]3x/3 = 234/3[/tex]

x = 78

Therefore, the daily room charge, in dollars per day, is $78 per day.

It has led the world on a continuing adventure of human exploration, discovery, and achievement. The center has played an important role in bringing the United States into the 21st century through technological inventions and scientific discoveries. The people who work at JSC have made advances in science, technology, engineering, and medicine. This has helped people explore our world and outer space and gain endless knowledge from that exploration.2 The Johnson Space Center was established in 1961 as the Manned Spaceflight Center. It was the home and Mission Control Center for the U.S. human spaceflight program. In 1973, it was renamed in honor of the late President, and Texas native, Lyndon B. Johnson. The Johnson Center's complex occupies 1,620 acres of land southeast of downtown Houston. JSC presently serves as the home of mission control, lead for NASA's International Space Station operations and missions, home to the Orion Multi-Purpose Crew Vehicle, and base for many other advanced human exploration projects.3 The Lyndon B. Johnson Space Center holds several artifacts that are worth a visit. For example, several historic space capsules are on display at the space center. They include the Faith 7 Mercury capsule flown by Gordon Cooper; Gemini 5, flown by Gordon Cooper and Pete Conrad; and the Apollo 17 Command Module, flown to the Moon and back by Gene Cernan, Ronald Evans, and Harrison Schmitt. NASA's latest-generation space capsule, Orion, is also on display.4 Along with the space capsules, the JSC holds the famous Lunar Module; it hangs from the ceiling. This spacecraft, named LTA-8, served as a test unit for astronaut training. The spacecraft from which six astronauts descended to the surface of the Moon had the same design as LTA-8. Their Lunar Modules acted as their base while on the Moon. Later, it helped them return to the Lunar Orbit when their stay was over. The Apollo 13 Lunar Module acted as a lifeboat after that flight's Service Module was damaged. It helped the crew return safely to Earth.5 NASA's robots called Robonauts are also designed at the Johnson Space Center. One such robot is currently at the International Space Station. The Space Vehicle Mockup Facility in Building 9 at the space center is a good place to see the Robonauts. Some tours let people see the inside of the building from above. Other special tours take people across the building floor for a close-up look at Robonauts and other wonders at the space center.6 The Lyndon B. Johnson Space Center is a wondrous place that displays the history of space exploration and the technology of the future, all under one roof.Which of these is an important idea expressed in the article?A.Lately, NASA has spent a lot of money to develop advanced robots that will help astronauts in deep space exploration.B.In recent times, space exploration has taken a new leap as NASA is aiming to send people to space to explore other bodies.C.NASA's Space Center helps children gain interest in science and astronomy and motivates them to become scientists.D.NASA's Space Center constantly works hard to develop technology that helps people understand space better.
