Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Trigonometry

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a legb is another legc is the hypotenuse

Step-by-step explanation:

Step 1: Identify

We are given a right triangle. We can use PT to solve for the missing length a.

Step 2: Define

hypotenuse c = 15

leg b = 9

leg a = ?

Step 3: Find missing length a

Substitute in variables:                    a² + 9² = 15²Isolate a term:                                  a² = 15² - 9²Exponents:                                       a² = 225 - 81Subtract:                                           a² = 144Isolate a:                                           a = ±12

Since we are not dealing with a quadrant triangle, we can disregard the negative root of the quadratic.

a = 12 is our final answer.

What is the length and width of the rectangle? \text{Width} =Width=start text, W, i, d, t, h, end text, equals

Answers

Answer:

This means that the width = 3y²

The length = 4y+7y³

Step-by-step explanation:

Given

Area of the rectangle = 12y^2+21y^5

Width of the rectangle is the greatest common monomial of 12y^2 and 21y^5

First let us get the greatest common monomial of 12y^2 and 1^5

12y^2 = (3  * y * y) * 4

21y^5 = (3 * y*y)*y*y*y* 7

Hence the greatest common monomial is 3 * y * y = 3y²

Factor out 3y² from the area function;

12y^2+21y^5

3y² (4y+7y³) = Area of the rectangle

Length * Width = 3y² (4y+7y³)

On comparing both sides of the equation

This means that the width = 3y²

The length = 4y+7y³

4y^2

Scientists studying biodiversity of amphibians in a rain forest have discovered that the number of species is decreasing by 2% per year. There are currently 74 species of amphibians in the rain forest. Which logarithmic function models the time, , in years, it will take the number of species to decrease to a value of n?

Answers

Answer:

Option A: f(x) = log_0.98 (n/74)

Step-by-step explanation:

We are told that that the number of species is decreasing by 2% per year.

Thus, number of species each year is 98% or 0.98 of number of species the previous year. .

We are told that there are currently 74 species of amphibians in the rain forest.

Thus, n/74 will represent a fraction of the current number of species.

Thus, the logarithmic function that models the time can be written as;

f(x) = log_0.98 (n/74)

Answer:

A. f(n) = log0.98(n/74)

Which subtraction expression
has the difference 1 + 4i?

O (-2+ 6i) - (1 - 2i)
O (-2+ 6i) - (1 - 2i)
O (3 + 5i) - (2 - i)
O (3 + 5i) - (2 + i)

Answers

Answer: d, (3+5i)-(2+i)

Step-by-step explanation:

i’m smart

The subtraction expression that has the difference 1 + 4i is (3 + 5i) - (2 + i).

Option D is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can find the difference 1 + 4i by subtracting the complex numbers in each expression and checking which one gives us the result of 1 + 4i.

Let's start with option (a):

(-2 + 6i) - (1 - 2i) = -2 + 6i - 1 + 2i = -3 + 8i

This is not equal to 1 + 4i, so option (a) is not the correct answer.

Let's move on to option (b):

(-2 + 6i) - (1 - 2i) = -2 + 6i - 1 + 2i = -3 + 8i

We have already seen this expression and it is not equal to 1 + 4i. Therefore, option (b) is also not the correct answer.

Let's move on to option (c):

(3 + 5i) - (2 - i) = 3 + 5i - 2 + i = 1 + 6i

This is not equal to 1 + 4i, so option (c) is not the correct answer.

Finally, we have the option (d):

(3 + 5i) - (2 + i) = 3 + 5i - 2 - i = 1 + 4i

This is equal to 1 + 4i.

Thus,

The subtraction expression that has the difference 1 + 4i is (3 + 5i) - (2 + i).

Why were enslaved people under Dutch rule able to access some legal rights, such as owning property, getting married, or petitioning for freedom?2. What may have been the benefits/ challenges associated with owning land as an emancipated slave?TEXT: The largest number of New Amsterdams enslaved people, including Maria Van Angola, came from the Kingdom of Angola, a major trading ally of Portugal and Holland; they were probably trafficked through the port of Luanda.We have no portraits or images of the enslaved and free Africans in New Amsterdam, but Dutch and Flemish artists depicted African people from similar backgrounds in the Netherlands in the 1500s and 1600s.Maria Van Angolas name suggests that she was born in the kingdom of Angola and came to New Amsterdam on the first shipload of enslaved people in 1626. She originally appears in the historical record in 1640, when she witnessed a baptism in the Dutch Reformed Church. Two years later she had a son named Dominicus baptized there.The Dutch had no clear laws defining or regulating slavery in the early 1600s. It was unclear what rights enslaved people might have or how they might become free. In this ambiguous situation, Maria Van Angola and others used several strategies to secure rights and freedom for themselves and their families, including legal action, church membership, and control of land.The Dutch system gave marriages between enslaved people official status. In November 1642, Maria and Anthony Fernando Portuguese, the father of her child, formally married in the Dutch Reformed Church. Anthony had already survived a dangerous brush with the law. Over the next seven years they had five more children and embarked on a long struggle for freedom and security for their family.Some enslaved people achieved legal standing in Dutch courts; they could own property, work for wages, and sue when they were not paid. In fact, legal records show that Marias husband had once sued for damages that a merchants dog had done to his pig. Access to the legal system became an important tool for African people in obtaining and defending their freedom.Some African-Dutch people had already encountered Christianity in Africa, and many joined the Dutch Reformed church in New Amsterdam in hopes of gaining freedom for themselves or their children. Maria Van Angola was an active church member for at least 41 years and acted as a witness for many baptisms.In 1643, as the colony was at war with the Mohawk nation, the Company emancipated 11 people. Each received a small plot of land (about 510 acres) north of the wall on todays Wall Street, where they could act as a buffer against Native incursions. These Africans were half-free, meaning that they were still expected to pay fees to the Company and their children would not be legally free.Owning land meant more than a farmit was a key to status as a freeholder with political rights. Listed among the original owners of small farms was a woman called Marycke who may have been Maria Van Angola. Over the next 19 years, 22 more emancipated people received small land grants as well, including Marias husband, Anthony Portuguese, in 1645.Maria Van Angola took advantage of the openness of the Dutch system. But near the end of Dutch rule, that openness was shutting down. The church began discouraging baptisms of Africans and land grants to Africans became more rare. The English takeover in 1664 shut the system down further, ending land grants, discouraging emancipation, and barring Africans from testifying in court. After the English took over New Amsterdam and named it New York, most of the African landowners sold their small plots or lost them in seizures. The English also clamped down in their control of the enslaved population; unlike Anthony Portuguese who was pardoned in 1641, the suspected leaders of slave revolts in 1712 and 1741 were burned at the stake.Maria managed to hold on, however. She retained her freedom through the changeover to English rule, and in 1681 she married a second time, this time to Bastiaen Mattheuszen, an African leader. They were listed in the church record as both living on the great [Hudson] river.The record shows that Marias adopted daughter, Susanna, held on to the family land until at least 1717. Susannas brother, Jochim, became an apprentice, learned to read and write, and joined the Dutch church in Hackensack, NJ. These hints suggest that the next generations continued to benefit from the freedoms that Maria and Anthony had fought for. if jesuss can walk on water can he swim on land what is the anwser -4+3(x+4)=-4+5x How many times bigger is 2 1/4 than 2 Hi guys :D Lol I need help (again) Umm why the hec am I so freaking lazy *send help* IDK WHY T.F I'M ASKING BUT PLZ HELP FOR REALhow is the setting important in the gentleman of rio en medio?
