The correct answer is **imperialism**.

Imperialism is when one country tries to extend its power over another country or territory. This can be done through warfare or the signing of treaties/agreements. The quote by Beveridge is discussing how American society is producing more goods than its ever produced and that the US needs to expand its power and influence over other countries. This would allow the excess goods and services to be sold to new consumers, generating more profits for business owners.

85%A=

Part A.

Consider the 150 marigolds.

After the first month, 0.85*150 are left

After the second month, 0.85*0.85*150=

After the third month, 0.85*0.85*0.85*150 =

.

.

so After n months, marigolds are left.

in functional notation: is the function which gives the number of marigolds after n months

consider the 125 sunflowers.

After 1 month, 125-8 are left

After 2 months, 125-8*2 are left

After 3 months, 125-8*3 are left

.

.

After n months, 125-8*n sunflowers are left.

In functional notation: S(n)=125-8*n is the function which gives the number of sunflowers left after n months

Part B.

marigolds are left after 3 months.

S(3)=125-8*3=125-24=121 sunflowers are left after 3 months.

Part C.

Answer : equalizing M(n) to S(n) produces an equation which is very complicated to solve algebraically.

A much better approach is to graph both functions and see where they intersect.

Another approach is by trial, which gives 14 months

which are close numbers to each other.

What theory was developed to justify investing in joint-stock companies for the new world?

company b: 60$ plus 5 times (how many hours)

PART A 70+four(x) B 60+5x

THE VARIABLE REPRESENTS THE HOURS THE TRUCK WAS RENTED

PART B company a charges 9four dollars to rent the truck

company b charges 90 dollars to rent the truck

PART C: you would have to solve the equation like this to find PART C

A: 70+four(7)=98 B: 60+5(7)=95

so the answer for part c would be he saved 3 dollars

**Answer:**

**High School P has the most consistent attendance among its students. **

**School N should be awarded for the highest average attendance.**

**Step-by-step explanation:**

Consider the provided information.

Part A: If the school district wants to award the school that has the most consistent attendance among its students, which high school should it choose and why? Justify your answer mathematically.

**Standard deviation (σ) is a measure of how a data set is spread out.**

**If the standard deviation is low, this implies that the information tends to be near to the set mean, whereas a high standard deviation implies that the information points are spread across a wider spectrum of values.**

Therefore, for more consistency we need to look for the low standard deviation.

From the provided table we can see that the school P has low standard deviation (σ) i.e 31.5

**Hence, High School P has the most consistent attendance among its students.**

Part B: If the school district wants to award the school with the highest average attendance, which school should it choose and why? Justify your answer mathematically.

**The formula for mean is:**

Mean is the same as average.

The sum of mean or average will be larger if each students contributes more attendance.

For highest average attendance the school with higher mean should be awarded.

**Hence, School N should be awarded for the highest average attendance.**

So, the number of ways is which 30 competitors from 50 can qualify is given by the formula of combinations, which is:

C (m,n) = m! / (n! * (m -n)! )

=> C (50,30) = 50! / (30! (50 – 30)! ) = (50!) / [30! (50 – 30)!] = 50! / [30! 20!] =

= **47,129,212,243,960 different ways the qualifiying round of 30 competitors can be selected from the 50 competitors.**

So, if you are told that one term of the polynomial is 9 x ^ (negative something), it is necessary that the number after the negative sign be negative, given that negative times negative is positive.

Therefore, the only possible option from the answer choices is the option 3) -9.

**Answer: 3) – 9**

The correct answer is **A) Political bosses were against women’s suffrage because they feared women might use their votes to end corruption.
**

*What the cartoonist imply about political bosses and the issue of women’s suffrage is that Political bosses were against women’s suffrage because they feared women might use their votes to end corruption.
*

Political bosses of the time did not want change. They had their personal agendas and many interests with other factions. A transformation for them was out of the question. Women’s suffrage represented an option for women’s rights an the possibility to make her voice heard, among other things, against corruption and oppression.

There are 20 alligators in the swamp. Each year, the number of alligators increases by 25%. There are 25 crocodiles in the swamp. Each year, 10 new crocodiles join the swamp. Part B: How many alligators are in the swamp after 4 years? How many crocodiles are in the swamp after the same number of years? Part C: After approximately how many years is the number of alligators and crocodiles the same? Justify your answer mathematically.

So, if you are told that one term of the polynomial is 9 x ^ (negative something), it is necessary that the number after the negative sign be negative, given that negative times negative is positive.

Therefore, the only possible option from the answer choices is the option 3) -9.

**Answer: 3) – 9**

**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.**

The First Amendment secures a few fundamental opportunities in the United States including flexibility of religion, the right to speak freely, the flexibility of the press, the privilege to gather, and the privilege to appeal to the administration. It was a piece of the Bill of Rights that was included in the Constitution December 15, 1791.

**Answer:**

**The integral roots of the equation are 0 and -2**.

**Step-by-step explanation:**

Here, the given equation,

——(1),

Since, at x = – 2,

Thus, x + 2 is a factor of ,

By dividing by (x+2),

We get,

Hence,

By equation (1),

If x + 2 = 0 ⇒ x = -2,

While, if x – (3 ± √3 ) = 0 ⇒ x = 3 ± √ 3

Thus the roots of the given equation are, **x = 0, – 2, 3 ± √3**,

Since, 0 and – 2 are integers,

⇒ **The integral roots of the equation are 0 and -2**.

16)

A) ∠GAE≅∠GEA

17) if y° =22° so angle A = 2y=then angle A=44°

Since this triangle ABC is isosceles (AB=AC given), then Angle B= Angle C

In a triangle we know that the sum of all angles =180°, the 44°+2C=180

& C= (180-44)/2 = 68 (C)

18) C)BC≅CE is not necessarily true

19) Reflexive Property; Given

20) Right Triangles ABC & AED are congruent::

CB=ED (given)

Angle C = D (given)

Angle B = E =90° (given)

The 2 triangles are congruent ASA & AC = AD

Now we have the equalities:

1) BC=ED ===> x=y-1

And

2) AC=AD ===> 3x-2 = 2y+1

Let’ arrange these 2 equations:

x-y = -1

3x-2y =3

Solving this system with 2 variables x & y gives: X=5 & Y=6 (D)

The correct answer is C. Demonstrates a lack of organization

Explanation:

A rubric is a tool used to assess or evaluate the quality of someone’s work such as essays or presentations. Because of this, in educational contexts, rubrics are widely used tools to assess students performance in some task assigned by the teacher. Rubrics are usually charts that work as scoring guides and that contain the criteria to evaluate some specific work, in this way, rubrics usually contain the aspects that will be evaluated such as coherence, development of ideas, grammar accuracy or organization and the levels of performance of these aspects expressed by qualifying words such as excellent, good, needs improvement or by a rate of numbers in which 1 or 0 shows the lowest level of performance. Additionally, each chart of a rubric describes the criterion according to each rate, for example, if you receive a rate of 0 for coherence the criterion for this would be “complete lack of coherence” or “a text that is not logically connected”. Considering this, the criterion that would give Dana a score of 1 in the organization category would be “Demonstrates a lack of organization” as a score of 1 is a synonym of the lowest level of performance which means Dana essay is not well organized.
