Answer:
(a) f(x) = 4x+1 (b) x = -1/4
Explanation:
Given that,
[tex]f(x) = 2x^2 + x - 6[/tex]
(a) We need to find f'(x).
[tex]f'(x)=\dfrac{d}{dx}(2x^2+x-6)\\\\=4x+1[/tex]
(b) We need to find the value of x when f'(x) =0
Put f'(x) = 0
4x+1 = 0
[tex]4x=-1\\\\x=\dfrac{-1}{4}[/tex]
So, the value is -1/4 when f'(x) = 0.
As Earth warms:
• Ice cover melts, exposing soil or water
• Albedo (Reflectivity of sunlight) decreases
• More energy is absorbed by Earth's surface
• Global temperature rises
• More ice melts
IS THIS A NEGATIVE OR POSITIVE FEEDBACK LOOP AND WHY?
it is negative because as the ice has melted, dark ocean water is said to be released and this leads to a lot of changes in the surface.
Is there an albedo increase or decrease when ice melts?Note that in global warming, there is a rise in feedback when there is reflective ice (that is, one has a higher albedo) when compared to land or water surfaces.
Conclusively, it is negative because as the ice has melted, dark ocean water is said to be released and this leads to a lot of changes in the surface and thus cause an albedo effect.

Researchers have found that the more World Cup soccer a student watches the better they do on their exams. Students reported the amount of World Cup soccer they had watched in the two weeks leading up to their midterm exams. The more soccer watched, the better the student’s exam grades tended to be. Researchers are not yet sure why soccer viewing improves intelligence, but plan further research during the next World Cup qualifiers as well as research examining other sports. Which of the following BEST captures the most significant flaw in this research as it is written? What type of design is this? Using an exam score as a measure of intelligence is an example of?
Answer:there could be a placebo effect that accounts for results
Explanation:
There is not enough info about experiment nor is there a group that didn’t watch soccer
Following are the solution to the given question:
For question 1:
The study is correlational, but still makes a causal claim the correlation just reveals the direction and size of such an association between variables; correlation does not imply causation.For question 2:
This researcher establishes a link between two variables, namely football viewing, and scoring. This correlational research looks into correlations between variables without helping researchers control or manipulates any of them. It expresses the strength and/or direction of a link between two (or more) factors. This correlation's direction could be either positive or negative.For question 3:
Parsimony is demonstrated by using an exam score as a measure of intellect. It is defined as extreme frugality or the practice of spending money with great prudence. When you carefully consider every purchase and are wary about spending even tiny sums of money.Therefore, the answer is "Option 1, correlational, and parsimony".

Answer:
The best way to learn psychology is through studying for a degree in psychology at a university.
Psychology is an empirical science. Its aim is to describe and explain human experience and behavior, their development in the course of life and all the internal and external causes and conditions that are relevant for them.
Therefore, it is a science that combines medical and social factors, of such complexity that its study must be regulated by university scientific academies.
"We hold these truths to be self-evident: that all men and women are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness; that to secure these rights governments are instituted, deriving their just powers from the consent of the governed. Whenever any form of government becomes destructive of these ends, it is the right of those who suffer from it to refuse allegiance to it, and to insist upon the institution of a new government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience hath shown that mankind are more disposed to suffer. while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute despotism, it is their duty to throw off such government, and to provide new guards for their future security. Such has been the patient sufferance of the women under this government, and such is now the necessity which constrains them to demand the equal station to which they are entitled." (2)

Which of the following would most likely increase the negative effects of nitrogen pollution?
Answer:
Loss of biodiversity in the wetlands.
Explanation:
Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.

What is the difference between curacy and precision
A) Accuracy is how far out the measurement is taken while precision is how close miested
value is to its true value
B) Accuracy is how close a measured value is to its true value, While precision is how okre
measured values are to each other
C) Accuracy is how close a measured value is to its true Vokie, Winte precision is how else the
average value is to the true value
D) Accuracy and precision are two different words for the same thing
Answer:
B) Accuracy is how close a measured value is to its true value, while precision is how close measured values are to each other
Explanation:
i. The true value is the actual or correct value of the quantity measured. So that accuracy describes how close a measured value is to the true value.
For example, a pencil of actual length 10 cm is given to 3 students to measure individually.
Assume that each student measures; 9.5 cm, 9.65 cm, 9.95 cm. Then it can be observed that the 9.95 cm measure is accurate compared with the actual value.
ii. Precision describes the closeness of measured values to each other.
For example, a pencil of actual length 10 cm is given to 3 students to measure individually.
Assume that each student measures; 9.5 cm, 9.55 cm, 9.60 cm. Then their measurements are precise, though not accurate.

x = number of people in the sample of 15 that have a food allergy.
Answer:
Number of people that have food allergy = 1 person (approx.)
Explanation:
Given:
Percentage of American have food allergy = 6 %
Number of people in survey = 15
Find:
Number of people that have food allergy
Computation:
Number of people that have food allergy = Number of people in survey x Percentage
Number of people that have food allergy = 15 x 6 %
Number of people that have food allergy = 0.9
Number of people that have food allergy = 1 person (approx.)
AP Human Geography Help
A. Describe TWO forces that affect the economic stability of cities. Provide a specific example of each.
B. Identify and explain how the forces identified above relate to the growth of metropolitan areas and megalopolises.
Answer:
Two forces that affect the economic stability of cities are unemployment and inflation.
Unemployment is rate of people available for and looking for work, but without a job. In turn, inflation is the constant increase in the prices of goods and services during a certain period of time.
Both variables negatively affect the economic stability of cities, since, on the one hand, unemployment limits the productive capacity of the city and causes less money to circulate in the internal economy, limiting the population's consumption capacity and therefore hence the income of the city's companies. In turn, inflation causes a rise in prices that limits the consumption possibilities of the population, as each individual needs more money to acquire the same goods.
Both problems have a direct correlation with the population increase in cities: unemployment because an excessive increase causes an excess of people looking for work in a market that does not adapt to this need; and inflation because the higher the demand for the products, the higher the price of them.

________________ (name the theoretical perspective) uses and believes in the scientific method to explore society.
Functionalism
Positivism
Conflict Theory
Symbolic Interactionism
Answer: Positivism
Explanation:
Positivism as a theoretical perspective uses logic to explain things. People who follow it believe that the world should be explored through the lenses of the scientific method because everything can be explained based on statistics and are only factual if proven by the scientific method.
They are therefore against the notion that things work due to metaphysical forces and also believe that knowledge cannot be acquired unless events confirming that knowledge have been experienced.
