The correct answer is a. Amy: wildlife in or near water = turtles, crayfish, goldfish non-water wildlife = fox, deer, bobcat.

Explanation:

According to the question students were asked to contrast their observations based on the location so according to the location, animals should be differentiated into water animals and land animals.

So turtles, crayfish, goldfish are the wildlife found in or near the water and fox, deer, bobcat are non-water animals according to their location. Therefore the correct answer is a. Amy: wildlife in or near water = turtles, crayfish, goldfish non-water wildlife = fox, deer, bobcat.

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.

## Dense water near the poles sinks, creating a current towards the equator. What would you expect to happen to this current if temperatures at the poles increased? A. The current would move to the surface B. Nothing would happen to the current C. The current would decrease in speed D. The current would increase in speed

The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies.

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface.

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h.

So the time for the pencil and eraser to touch is T=1.3449 hours.

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

## A woman who had a cesarean birth of twins 6 hours ago reports shortness of breath and pain in her right calf. what complication should the nurse expect?

“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.

Lawrence Kohlberg felt that one of the only ways individuals will accomplish the objectives in each of his six stages was to participate in “consensus democracy” in small group settings.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s. The hypothesis is that when understudies are given the help they require while discovering some new information, they stand a superior possibility of utilizing that learning freely. Bruner suggests positive association and three methods of portrayal amid educating: activities, pictures, and dialect.

## Read this paragraph from The Dark Game. It may seem surprising that no Confederate sympathizers took action against Van Lew, given her strong and public views on secession and slavery. Surely there were suspicions, especially among her upper-crust neighbors, but the matter never went beyond those suspicions. Historians have suggested that the secessionists were victims of their own cultural bias, believing that no aristocratic person, and certainly not a lady, would ever consider taking part in anything as impolite as spying. A true lady managed her servants, prepared parties and gatherings, and blindly supported her husband. Such attitudes worked in Van Lew’s favor, diverting suspicion from her. What central idea is implied in this paragraph? A-Elizabeth Van Lew did not follow the rules society set forth for ladies of her time and social class. B-Elizabeth Van Lew was a successful spy because society did not expect a lady to serve in that role. C-Elizabeth Van Lew was able to disguise her spying activities because she kept her views about the war to herself. D-Elizabeth Van Lew created for herself an untrue but believable cover story: she was a wealthy lady living in a fancy neighborhood.

Hey there!

Correct answer is D. Comma or Period Inside Rule

A. Question mark or exclamation point inside: those are not really necessary.

B. Colon or semicolon: not, a semicolon would divide the whole sentence and it would be shorten; a colon would work but after requested, when there is already a comma.

C. Question mark or Exclamation Point Outside Rule: would not work, becase it is an very polite and affirmative sentence.

D: A comma or period inside rule: actually, just a comma would work. Please, Cooper’s dad requested, go… Cooper’s dad requested must be in between commas as it is a vocative.

## One would expect that the cross price elasticity of ski poles and skis would be a. positive since they are substitutes. b. negative since they are substitutes. c. positive since they are complements. d. negative since they are complements.

The following equation of parabola is given:

p(x)= – 5 x^2 + 240 x – 2475

where p(x) = y

This is a standard form of the parabola. We need to
convert this into vertex form of equation. The equation must be in the form:

y – k = a (x – h)^2

Where h and k are the vertex of the parabola. Therefore,

y = – 5 x^2 + 240 x – 2475

y = -5 (x^2 – 48 x + 495)

Completing the square:

y = -5 (x^2 – 48 x + 495 + _) – (-5)* _

Where the value in the blank _ is = -b/2

Since b = -48        therefore,

y = -5 (x^2 – 48 x + 495 + 81) + 405

y – 405 = -5 (x^2 – 48 x + 576)

y – 405 = -5 (x – 24)^2

Therefore the vertex is at points (24, 405).

The company should make 24 tables per day to attain maximum

## If 1,000 students take a test that has a mean of 40 minutes, a standard deviation of 8 minutes, and is normally distributed, how many would you expect would finish in less than 40 minutes?

The answer must take into account that the order is irrelevant, that is that it is the same J, Q, K that Q, K, J, and K, J, Q and all the variations of those the three cards.

The number of ways you can draw 50 cards from 52 is 52*51*50*49*48*47*…4*3 (it ends in 3).
,
But the number of ways that those 50 cards form the same set repeats is 50! = 50*49*49*47*….3*2*1

So, the answer is (52*51*50*49*48*….*3) / (50*49*48*…*3*2*1) =  (52*51) / 2 = 1,326.

Note that you obtain that same result when you use the formula for combinations of 50 cards taken from a set of 52 cards:

C(52,50) = 52! / [(50)! (52-50)!] = (52*51*50!) / [50! * 2!] = (52*51) / (2) = 1,326.

## Which word best describes Michelle Obama’s tone in this statement? “We as parents are our children’s first and best role models, and this is particularly true when it comes to their health. We can’t lie around on the couch eating French fries and candy bars, and expect our kids to eat carrots and run around the block. But too often, that’s exactly what we’re doing.”

Here are a few pointers; hope this is useful)

Ovation-by definition- is show of appreciation from an audience, for a person’s accomplishments or flaw.

“Everyone deserves a standing ovation because we all overcometh the world.”

A person’s accomplishment could be how they made a positive change in this world, strong leadership- that makes them a effective leader or simply helping others. A person’s flaw- mistakes in life, sin or even guilt should also be considered an appreciation- an ovation for representing mankind’s flaw and that humanity makes mistakes, fulfilling at least one deadly sin such as greed, lust, selfishness etc.

Thus, regardless of a person’s achievement or flaw- a person deserves an applause for, not the least, living in this society and this world that we are all living together and dying together.

That was just the introduction.. the best part is yet to come.. now it’s your turn!!

Shakespeare’s famous line “All the World’s a stage. That agrees with your line: “Everybody deserves a standing ovation…”

Shakespeare explains that men and women are like players: they live, and die, some being celebrated and some forever living in solitude till their death. Shakespeare states the world is a “stage” which symbolizes that mankind is in its peak. The world is changing everyday: little by little and humanity is falling behind.
Due to our world turning into machinery: factories, an automotive future: where humans only job to live (entrance) and to die (exit) the famous humans remembered and the flawed not recalled.

This is according to Shakespeare’s imagery.

I don’t know what grade your in, but I think simplifying Shakespeare’s word of mouth in your essay would be handy and useful as it has strong references of your quote, and agrees strongly in your essay.

Hope this helps 🙂

Stock A:

Zachary bought 40 shares of stock A at \$80 a share. So he paid 40*80 = 3200 dollars for the shares of stock A.

He then sells stock A at \$83 a share, so 83*40 = 3320 is the amount he gets back. The net result is 3320-3200 = 120. Divide this over the initial cost to get 120/3200 = 0.0375

So the rate of return (ROR) for stock A is 3.75%

—————————————

Stock B:

total cost = (number of shares of stock B)*(cost per share of stock B)
total cost = 80*160
total cost = 12800

Then he sells stock B at \$166 a share

80*166 = 13280

He nets 13280 – 12800 = 480 dollars from stock B

The ROR for stock B is 480/12800 = 0.0375 = 3.75%

So far, we see that the ROR for both stocks (A and B) are the same at 3.75%

—————————————

Bond:

par value = \$1000
coupon = (0.0525)*(1000) = \$52.50

ROR = (coupon)/(price) = 52.50/775 = 0.0677 = 6.77%

—————————————

In summary, we have

ROR for stock A = 3.75%
ROR for stock B = 3.75%
ROR for bond = 6.77%

Stock A and B have a tie for the lowest ROR

so that’s why the answer is choice 1) Stock A and Stock B

## Which property would you expect an element in Group 5 of the periodic table to possess? A. It will not be malleable. B. It will not transfer heat. C. It will conduct electricity. D. It will react with halogens.

The answers B,C, and D are correct.

Government is the governing authority of a nation or political unit, whose purpose is to regulate and organize society. The size of the government will vary according to the size of the state and may be local, regional and national. Within a government, there may be many types of political regimes, some that are highly concerned about the freedom and well being of the population such as minimal state – which is when there are few duties for the government and high economic, political and social freedom, and some historically bad government regimes such as tyranny. Despite them, we also have democracy, dictatorship, oligarchy, and so on.

In contemporary times, democracy is considered the most common political regime in governments and also the most demanded by the people. In general the government “good or useful” is elected by the community to remedy its deficiencies and represent its desires as a whole. Common desires are libraries, parks, transportation, schools and other public needs.

## How to answer what wage you expect on job applications?

b. they give foreign goods a competitive edge

c. they protect local industry

Protective tariffs are considered positive because they give foreign goods a competitive edge and they protect local industry.

Explanation:

Protective tariffs refer to taxes imposed on imported goods and services in order to increase prices of imports and protect local industries from competition. It is also imposed on imported goods to encourage the growth of local industries. This makes the sales of locally produced goods to rise and imported goods to come down.

## In autobiographies, narrators tell the story of their own lives. From which point of view would you expect an autobiography to be written? first person third person limited third person omniscient

The expected point of view in autobiographies is the following one:

First person.

Explanation:

Since autobiographies are books in which people narrate the events in their own lives, it is only natural that the point of view of choice will be first person, that is, with the prevalence of the pronoun “I”. Plus, a rather personal tone is used, as in this excerpt from “My Life”, by Bill Clinton, former President of the USA:

“At the end of my presidency, I picked a few special places to say goodbye and thanks to the American people. One of them was Chicago, where Hillary was born; where I all but clinched the Democratic nomination on St. Patrick’s Day 1992; where many of my most ardent supporters live and many of my most important domestic initiatives in crime, welfare, and education were proved effective; and, of course, where my parents went to live after the war. I used to joke with Hillary that if my father hadn’t lost his life on that rainy Missouri highway, I would have grown up a few miles from her and we probably never would have met.”

## We toss two dice 1,000 times. How many times do we expect to have the sum of the two dice equal to 4?

This question can be solved by a system of equations.
Let’s use x and y to represent the numbers.
“Sum” refers to addition, while “difference” refers to subtraction.
If the sum of x and y is 12, then that means x + y = 12.
If the difference between x and y is 4, then that means x – y = 4, or y – x = 4. Both work since neither are known and their order doesn’t change the outcome in the first equation either due to it being addition.

Now we have the system of equations of x + y = 12 and x – y = 4.
{ x + y = 12
{ x – y = 4
To solve this, change one of the equations into slope-intercept form and use the substitution method.
Steps to the substitution method:
– Isolate one of the variables in one of the equations in the system.
– Substitute the expression equal to that variable into the other equation.
– Solve the other equation for a variable.
– If needed, plug the value of the found variable into the still-unknown equation and solve.

Let’s isolate x in x – y = 4.
To isolate a variable, remove all other terms from the side of the equation the variable is on by doing the inverse of what is being done to those terms. Remember to do the same thing to both sides!
To isolate x in x – y = 4, add y to both sides.
x – y + y = x
4 + y = 4 + y
x = 4 + y
Now x is isolated!

Now plug the expression equal to x into the other original equation.
x = 4 + y
x + y = 12
(4 + y) + y = 12
We can remove the parentheses without affecting the outcome, since the order of addition doesn’t change the result.
4 + y + y = 12
Combine like terms.
The like terms in this case are y and y, which combine to get 2y.
4 + 2y = 12
Isolate the variable.
First, subtract 4 from both sides.
4 + 2y – 4 = 2y
12 – 4 = 8
2y = 8
Divide both sides by 2.
2y / 2 = y
8 / 2 = 4
y = 4

Now we know one of the numbers!
Now we plug the value of this known variable, y, into the other equation in the system so we can find the value of x.

x + y = 12
y = 4
x + 4 = 12
All we have to do is isolate the variable of x by subtracting 4 from both sides!
x + 4 – 4 = x
12 – 4 = 8
x = 8

Now we know both of the numbers!
The numbers who’s sum is 12 and difference is 4 is 8 and 4.

Let’s check this!
Sum of two numbers = 12
8 + 4 = 12
This works! Now let’s check the difference!
Difference = Subtraction
Difference of two numbers = 4
8 – 4 = 4
This is true as well, meaning 8 and 4 are the correct answers!

8 and 4

Hope this helps!

There are four variables which govern changes in population size.
births
deaths
immigration
emigration

A population gains individuals by birth and immigration and loses individuals by death and emigration.

Biotic Potential
Populations vary in their capacity to grow. The maximum rate at which a
population can increase when resources are unlimited and environmental
conditions are ideal is termed the population’s biotic potential. Each
species will have a different biotic potential due to variations in
the species’ reproductive span (how long an individual is capable of reproducing)
the frequency of reproduction (how often an individual can reproduce)
“litter size” (how many offspring are born each time)
survival rate (how many offspring survive to reproductive age)

There are always limits to population growth in nature. Populations
cannot grow exponentially indefinitely. Exploding populations always
reach a size limit imposed by the shortage of one or more factors such
as water, space, and nutrients or by adverse conditions such as disease,
drought and temperature extremes. The factors which act jointly to
limit a population’s growth are termed the environmental resistance. The interplay of biotic potential and density-dependent environmental resistance keeps a population in balance.
Carrying Capacity
For a given region, carrying capacity is the maximum number of
individuals of a given species that an area’s resources can sustain
indefinitely without significantly depleting or degrading those
resources. Determining the carrying capacities for most organisms is
fairly straightforward. For humans carrying capacity is much more
complicated. The definition is expanded to include not degrading our
cultural and social environments and not harming the physical
environment in ways that would adversely affect future generations.

For populations which grow exponentially, growth starts out slowly,
enters a rapid growth phase and then levels off when the carrying
capacity for that species has been reached. The size of the population
then fluctuates slightly above or below the carrying capacity.
Reproductive lag time may cause the population to overshoot the carrying
capacity temporarily. Reproductive lag time is the time required for
the birth rate to decline and the death rate to increase in response to
resource limits. In this scenario, the population will suffer a crash
or dieback to a lower level near the carrying capacity unless a large
number of individuals can emigrate to an area with more favorable
conditions. An area’s carrying capacity is not static. The carrying
capacity may be lowered by resource destruction and degradation during
an overshoot period or extended through technological and social
changes.

An example of dieback occurred in Ireland after a fungus infection
destroyed the potato crop in 1845. During this potato famine
approximately 1 million people died and 3 million people emigrated to
other countries. Increased food production due to improved agricultural
practices, control of many diseases by modern medicine and the use of
energy to make historically uninhabitable areas of Earth inhabitable are
examples of things which can extend carrying capacity. The question is
how long will we be able to keep increasing our population on a planet
with finite size and resources?
