Observa el siguiente rectángulo:Si su área es x² + x – 6, ¿cuál de las siguientes factorizaciones presenta correctamente el producto de su base por su altura? *

Answers

Answer 1

The perimeter of the rectangle is given by 4x+2.

The area of a rectangle is given by the formula A=l*w where l is the length and w is the width. In this case, the area is given by the equation x^2 + x - 6. To find the perimeter of the rectangle, we need to know the length and width. However, since the area is represented by an equation, we do not have a specific value for the length and width. The given equation x^2 + x - 6 is a quadratic equation which can be factorised as (x-2)(x+3). So, we can't find the length and width without the value of x. To find the perimeter of a rectangle we use the formula P=2(l+w). If we know the value of x, we can find the perimeter of rectangle. But, as we don't have the value of x, we can't find the perimeter of the rectangle

Assume that each full-time worker works four 40 hour work weeks per month and each part-time worker works four 40 hour weeks per month.

Answers

Answer

Full-time worker minimum monthly income = US$ 7,846.40

Part-time worker minimum monthly income  = US$ 7,846.40

Full-time worker hourly wage = US$ 49.04

Part-time worker hourly wage = US$ 98.08

Explanation:

1.Review the information

Monthly costs of a 2-adult and 3-children family in the Modesto metro area = US$ 5841

Full-time worker = 4 weeks of 40-hour per month

Part-time worker = 2 weeks of 40-hour per month

2. Let's calculate the minimum monthly income and hourly wage per worker

Full-time worker hourly wage = Monthly costs/160

Part-time worker hourly wage = Monthly costs/80

Full-time worker hourly wage = 5841/160

Part-time worker hourly wage = 5841/80

Full-time worker hourly wage = US$ 36.5

Part-time worker hourly wage = US$ 73

Full-time worker minimum monthly income = Hourly wage * 160

Part-time worker minimum monthly income  = Hourly wage * 80

Full-time worker minimum monthly income = US$ 5840

A rocket is launched upward in the air. The height of the rocket t seconds after it is released is approximated by the function.
h=16t^2+96t+10
a) Find the number of seconds that it takes for the rocket to reach the ground.

b) find the number of seconds that it will take the rocket to be at its highest maximum height.

c) find the maximum height of the rocket.

Answers

Step-by-step explanation:

a) To find the number of seconds that it takes for the rocket to reach the ground, we need to find the value of t when h = 0. We can set h = 0 and solve for t:

0 = 16t^2 + 96t + 10

To solve for t we need to use the quadratic formula:

t = (-b ± √(b^2 - 4ac))/2a

Where:

a = 16, b = 96 and c = 10

t = (-96 ± √(96^2 - 41610))/2*16

t = (-96 ± √(9216 - 640))/32

t = (-96 ± √(8576))/32

t = (-96 ± 92.8)/32

So the rocket will take approximately 2.89 seconds to reach the ground.

b) To find the number of seconds that it will take the rocket to be at its highest maximum height, we need to find the value of t when the derivative of h is equal to 0.

h' = 32t + 96

h' = 0

32t + 96 = 0

t = -3

So the rocket will take approximately -3 seconds to be at its highest maximum height.

c) To find the maximum height of the rocket, we need to substitute the value of t from part b into the equation for h:

h = 16(-3)^2 + 96(-3) + 10

h = 169 + 96(-3) + 10

h = 144 - 288 + 10

h = -134

So the maximum height of the rocket is approximately -134 feet.

Arnold is testing a new train locomotive on circular rail track with a radius of 0. 9 kilometers. How many times around the track does Arnold need to run the train to cover a distance of at least 50 kilometers?

Answers

So, Arnold needs to run the train 9 times around the track to cover a distance of at least 50 kilometers.

We know that the radius of the circular rail track is 0.9 kilometers, so the circumference of the track can be found using the formula C = 2πr, where C is the circumference and r is the radius of the circle.

C = 2 * 3.14 * 0.9 = 5.652 km

To find out how many times Arnold needs to run the train around the track to cover a distance of at least 50 kilometers, we need to divide 50 by the circumference of the track.

50 km / 5.652 km = 8.9

Arnold needs to run the train around the track approximately 8.9 times to cover a distance of at least 50 kilometers.

To be more precise, we can round up the result, so Arnold needs to run the train 9 times around the track to cover a distance of at least 50 kilometers.

What is the polynomial after simplification

The polynomial (x – 2)(x^2 + 1) – x(x – 3) can be written as:

ax^3 + bx^2 + cx + d = (x - 2)(x^2 + 1) - x(x - 3)

To find the values of a, b, c, and d, we need to multiply out the binomials and combine like terms. Using the distributive property, we get:

it takes bill 2 hours longer to do a certain job than it takes cindy. they worked together for 2 hours, then cindy left and bill finished the job in 1 hour. how long would it take each of them to do the job alone

Answers

It takes Cindy 1 hour to do the job alone and Bill 3 hours to do the job alone.

Let x be the time it takes Cindy to do the job alone, in hours. Then, it takes Bill x + 2 hours to do the job alone.

During the first 2 hours, when they worked together, they did 2/x + 2/(x + 2) = 1/2 of the job.

Bill finished the job in 1 hour after Cindy left, so he did 1/x + 2 = 1/3 of the job during that hour.

We can now set up a system of two equations to solve for x:

2/x + 2/(x + 2) = 1/2 (1)

1/x + 2 = 1/3 (2)

From equation (1), we can find x + 2:

2/x + 2/(x + 2) = 1/2

2x + 4 = x(x + 2)

2x + 4 = x^2 + 2x

x^2 - 2x + 4 = 0

(x - 4)(x - 1) = 0

x = 4 or x = 1

Since x represents the time it takes Cindy to do the job, we reject x = 4 and keep x = 1.

Substituting x = 1 into equation (2), we find:

1/1 + 2 = 1/3

3 = 3

So, it takes Cindy 1 hour to do the job alone and Bill 3 hours to do the job alone.

Therefore, It takes Cindy 1 hour to do the job alone and Bill 3 hours to do the job alone.

2x + 4 = x² + 2x

x² - 2x + 4 = 0

(x - 4)(x - 1) = 0

x = 4 or x = 1

Since x represents the time it takes Cindy to do the job, we reject x = 4 and keep x = 1.

Substituting x = 1 into equation (2), we find:

1/1 + 2 = 1/3

3 = 3

So, it takes Cindy 1 hour to do the job alone and Bill 3 hours to do the job alone.

Therefore, It takes Cindy 1 hour to do the job alone and Bill 3 hours to do the job alone.

a relation where every input has exactly one output

Answers

Function is a relation where each input has exactly one output.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output. Each function has a range, co domain, and domain. The usual way to refer to a function is as f(x), where x is the input.

The link between INPUT and OUTPUT is demonstrated by the relation. A function, on the other hand, is a relation that yields one OUTPUT for each given INPUT.

Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co domain, respectively.

geologists have an interest in the structure and the history of the earth. a geologist can go back in time by drilling deep into the ground, retrieving a core sample, estimating the ages of the various layers, and examining the composition. a timeline can be built of the entire area from where the core sample was drilled. a geologist may retrieve several core samples to confirm the history of the earth's structure in that sampled area. mountains, lakes, and unstable ground can easily impede a simple random sampling of a desired geographical area, therefore what is the most realistic sampling method that represents the actual drillings, comparisons, and scientific examinations of several core samples within the same geographical area?

Answers

The most realistic sampling method that represents the actual drillings, comparisons, and scientific examinations of several core samples within the same geographical area is Cluster Sampling technique.

In cluster sampling, the total population is divided into homogeneous groups known as clusters and a simple random sample of the groups is selected. The elements present in each cluster are then sampled like a sample. In other words we can say each cluster is represent a tiny population set. We have, geologists have an interest in the structure and the history of the earth. In this study, the whole population is divided into groups based on retrieving a core sample, estimating the ages of the various layers, and examining the composition. After that a timeline can be built of the entire area for drilling the core sample. So, each set work as small population i.e., clusters. The sampling technique which is used here to represent the actual drillings, comparisons, and scientific examinations of several core samples within the same geographical area is known as cluster sampling.

Why is the distance between two points always represented by a positive number?

Answers

Because the x and y coordinates are squared before being added together, the formula will always result in a positive number.

In math, what is a distance?

The length of the segment of the line that connects the supplied two points determines the distance between them.

                     The shortest segment of a line connecting a point to a line will have a length equal to the distance between them.

Why does the distance formula work?

The Pythagorean Theorem, which states that a side plus a side plus a side equals a side equals a side equals a side equals a side equals a side equals a side equals a side equals a side, is where the Distance Formula actually originates (known as the legs of a right triangle).

susie buys 3 pieces of pizza and 2 cookies for a total of 6.50. the next day she buys 1 piece of pizza and 1 cookie for 2.50. how much does a cookie cost

Answers

Answer:

  1.00

Step-by-step explanation:

You want to know the price of a cookie when 3 pizza slices and 2 cookies cost 6.50, while 1 pizza slice and 1 cookie costs 2.50.

Elimination

We can write equations for the costs as ...

  3p +2c = 6.50

  p + c = 2.50

Multiplying the second equation by 3 and subtracting the first equation eliminates the variable p.

  3(p +c) -(3p +2c) = 3(2.50) -(6.50)

  3p +3c -3p -2c = 7.50 -6.50 . . . . . . . eliminate parentheses

  c = 1.00 . . . . . . . . . simplify

The cost of a cookie is 1.00.
