## You used three methods of analysis to find the acceleration of the cart on the track: a two-point difference from v(t), an average of a(t) that was itself calculated by a succession of first differences of the v(t) data, and a line fit to v(t). some criteria to help you consider which method is best are part a in which type of graph(s) is it easiest to see whether the acceleration was constant?

The best way to find that you want is the line fit. When acceleration is constant the speed(v) changes smoothly every moment, so the v line must be straight. Differently, the accelaration changes.

We want to use the Addition-Subtraction method to solve
8.92x – 5.42y = 3.41             (1)
5.83x + 1.07y = 2.37             (2)

We shall eliminate y from the two equations by Addition.
Multiply (1) by 1.07 and multiply (2) by 5.42  to obtain
1.07*(8.92x – 5.42y) = 1.07*3.41
9.5444x – 5.7994y = 3.6487        (3)

5.42*(5.83x + 1.07y) = 5.42*2.37
31.5986x + 5.7994y = 12.8454   (4)

Add (3) and (4) to obtain
9.5444x – 5.7994y + 31.5986x + 5.7944y = 3.6487 + 12.8454
41.143x = 16.4941
x = 0.4009

From (2), obtain
1.07y = 2.37 – 5.83x
= 2.37 – 5.83*0.4009
= 0.0328
y = 0.0307

x = 0.4009
y = 0.0307

## What is a method of revealing information about a character by showing the characters words and actions

A method of revealing information about a character by showing the characters’ words and actions is called Indirect characterization.

Explanation:

There are two kinds of characterization direct and indirect. When a writer uses direct characterization they describe the character to the readers adding the adjectives that can describe them in the narrative. Indirect characterization uses different elements like Speech, Thought, Effect on others, Actions and Looks.

## How did advancements in physics, chemistry, and astronomy help cause the Enlightenment? Enlightenment thinkers applied the scientific method to social problems. Enlightenment philosophers began their careers as natural scientists. Knowledge of physics and chemistry enabled advances in weaponry and machinery. The study of science inspired great Enlightenment poets to write about nature.

The Enlightenment is known by that name because people considered the scientific progress brought a “new light” that could replace religion and leave the Middle Age behind. Also, different discoveries and studies in physics, chemistry, and astronomy established the scientific method as a reliable way to produce knowledge. Therefore, Enlightenment thinkers applied the scientific method to social problems, and since then, multiple social sciences like sociology or anthropology have adopted this method until the present day.

## Jason corporation has invested in a machine that cost \$75,000, that has a useful life of fifteen years, and that has no salvage value at the end of its useful life. the machine is being depreciated by the straight-line method, based on its useful life. it will have a payback period of six years. given these data, the simple rate of return on the machine is closest to: (ignore income taxes in this problem.)

We can solve
this problem by first calculating the annual net cash inflow. This can be
solved by remembering that:

Payback period
= Initial investment / Annual net
cash inflow

6 years = \$75,000
/ Annual net
cash inflow

Therefore,
Annual net
cash inflow = \$12,500

Next, we
calculate for the cost. The cost we will consider here is the depreciation
value of the machine.
Annual depreciation
= \$75,000 / 15 years = \$5,000

Therefore the annual net operating income is:
Annual net operating income = \$12,500 – \$5,000 = \$7,500

Simple rate of
return is calculated by:
Simple rate of
return = Annual net operating income / Initial
investment
Simple rate of
return = \$7,500 /
\$75,000 = 0.1 = 10%

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

## Which is the best method for visually representing the data for comparison

1. DNA

2. Prokariotic.

3. Crossing over.

4. Maple tree

5. Primary producers.

6. DIAGRAM NOT SHOWN

7. Lipids.

8. A

Explanation:

1. DNA is the macromolecule responsible for carrying the herederitary information of all cells, and even some viruses, with the exception of retroviruses.

2. Prokariotic cells (eubacteria and archeas) are cosmopolite, and lacks a membrane defined nucleus.

3. Crossing over.

During meiosis, homolog chromosomes pair and exchange genetic material, is also known as genetic recombination. This makes the chromosomes inherited not exactly equal to the corresponding from our fathers, or grandfathers.

4. Maple tree belongs to the clade Angiosperms: flowering plants, which produce seeds. Moss is a flowerless plant, this does not produce seeds. Lichen are composed from algae and cyanobacteria (so, not plants). Mushrooms are not plants.

5. Primary producers, such as bacteria and algae, can make organic  molecules from an abiotic source of energy.

6. DIAGRAM NOT SHOWN

7. Lipids are the main component of all biological membranes. In animals, specially cholesterols prevents the membrane from freezing, due its molecular structure. Tryglicerids, for example, provides besides thermal insulation, energy storage, filling space for keeping the organs together, among other functions.

8. The phosphorous is very slow, since it requires the extraction from rocks, starting from metereological processes (rain, erosion), Once in the soil, bacteria, fungi, plants and animals start to absorb it.

## Identify the sampling method used. every third student signing up for astronomy class is asked about telescope preferences.. a. systematic c. stratified b. random

The Venn diagram is not included, so I am going to explain the procedure and you will be able to calculate the result just plugging the numbers.

From Vend diagram you will be able to conclude two numbers:

1) the total number os students surveyed that participate in band (B)

2) the total number of students surveyed that participate in track (T)

3) the total number of students surveyed that participate in both band (B) and track (T) = B∩T

4) ) the total number of students surveyed, which is: total number of students in band B + total number of students in track – less the number of students that participate in both. = B + T – (B∩T)

So, the probability that one student that participate in band (B) also participate in track (T) =

Number of students that participate in both / number of students that participate in band = (B∩T) / B

Now, you just have to find B∩T and B from the diagram and plugg in into the formula (B∩T)/B. That’s it.

## What is the answer to 5x + 3y =31 and 2x+3y= 25 using elimination method

The basis to respond this question are:

1) Perpedicular lines form a 90° angle between them.

2) The product of the slopes of two any perpendicular lines is – 1.

So, from that basic knowledge you can analyze each option:

a.Lines s and t have slopes that are opposite reciprocals.

TRUE. Tha comes the number 2 basic condition for the perpendicular lines.

slope_1 * slope_2 = – 1 => slope_1 = – 1 / slope_2, which is what opposite reciprocals means.

b.Lines s and t have the same slope.

FALSE. We have already stated the the slopes are opposite reciprocals.

c.The product of the slopes of s and t is equal to -1

TRUE: that is one of the basic statements that you need to know and handle.

d.The lines have the same steepness.

FALSE: the slope is a measure of steepness, so they have different steepness.

e.The lines have different y intercepts.

FALSE: the y intercepts may be equal or different. For example y = x + 2 and y = -x + 2 are perpendicular and both have the same y intercept, 2.

f.The lines never intersect.

FALSE: perpendicular lines always intersept (in a 90° angle).

g.The intersection of s and t forms right angle.

TRUE: right angle = 90°.

h.If the slope of s is 6, the slope of t is -6

FALSE. – 6 is not the opposite reciprocal of 6. The opposite reciprocal of 6 is – 1/6.

So, the right choices are a, c and g.

Natural Forces Affecting the Driver:

1. While the car stops, the person continues moving the way that the car were moving and then hits the obstacle in the car or the person can be thrown out of the vehicle. If the person wears belt, he will stop moving with the vehicle and won’t hit the obstacle.

2. We count approximate kinetic energy using the formula K = v^2. So the vehicle which is moving at 30 mph will have four times less kinetic energy than vehicle which is moving at 60 mph. If they have the same road conditions, the breaking distance will be four times as great for the car moving twice as fast.

3. Kinetic energy depends on object’s mass and velocity and it has direct relationship with the stopping distance. The lesser mass of the vehicle = the lesser kinetic energy and lesser stopping distance. => If both vehicles have the same velocity, then small vehicle has lesser kinetic energy than large vehicle.

4. We know that kinetic energy has this relationship with velocity K = v^2. So the best way to prepare to enter sharp curves in the roadway is to lower the speed. The most appropriate speed is 20-30 mph, but it depends on road conditions and car’s breaks condition.

5. Car crashes can happen with everyone so the best way is to be prepared. First the driver should wear a seatbelt while he’s driving. He should check his tires and breaks condition regularly. And also it’s important to slow down the vehicle while entering sharp curves. Without following these rules, the driver can get catastrophic injuries in a car crash.

Signs, Signals, and Pavement Markings:

1. It doesn’t matter where you go. All you need is to learn highway code. It’s very different to know the meanings of every road sign. Also, it’s necessary to check your car’s conditions and you should take some spare parts for your car in case of accidents. So wherever you go, it’s important to be prepared.

2. You should stop before crossing and take few minutes to make sure there is no train approaching. If there is no train approaching, you can pass a railroad crossing. If you see approaching train, you should wait until it will pass a railroad crossing.

3. You should stop before the lights and wait to check the traffic movement and signs. Make sure that everything is safe and pass the intersection. Don’t move fast to avoid accidents.

4. Flashing yellow light means that it’s not necessary to stop but you should to pay attention on the traffic movement. So it would be better to yield before the lights and make sure if it’s safe to move. After that you can cross the intersection.

5. The line change means that the lane changes and you can’t cross solid lines. Pay more attention on road marking because it shows how you should behave on the road or highway.

6. As you approach the next exit and  your passengers need to use the restroom and get some food, you should look for green signs which indicate food and rest stops. You should to slow down if you don’t want to skip the sign.

7. When you take the exit ramp off the expressway and merge onto the next road, you see yellow lines dividing the roadway which indicates that there is oncoming traffic and this is a two-way highway.

Hey there!

Let’s assume that this question is referring to every digital calendar ever made. As in, even those made on devices without internet connectivity or any other fancy features that we utilize with many digital calendars today.

If a planning device that came with a digital calendar didn’t have internet connectivity, it wouldn’t be able to be connected to the cloud. Back when these devices were around, it wasn’t even plausible to store things like calendar events and contacts in what we know as the “cloud”. Also, these devices probably had to be hardwired to a computer and new software had to be downloaded to them, so the updates weren’t automatic. Archaic, right?

Also, consider the fact that even reputable websites/companies such as Google with Google Calendars or Apple with iCalendar will never go without their malfunctions or threats. Sometimes, these websites can be hacked and the data that they contain can be compromised, especially if they’re stored on the cloud. Also, even though it’s not realistic, Google or Apple could one day decide to completely get rid of their calendar programs altogether. So, this means that digital calendars are definitely able to be destroyed or lost.

That just leaves “They can be used anywhere”. This is true, even with those archaic devices specifically used for scheduling events and such. Nowadays, you have your phone and possibly a laptop on you at all times, which will likely have a calendar on it as a stock application. So, I think this is your answer.

Hope this helped you out! 🙂
