in the xy-coordinate plane, the points (4, 2) and (-1, k) are on a line that is perpendicular to the line y = 2x + 1. What is the value of k?
Answer: The value of x is 7/5
Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Letter C, E, and F: 2 8/10, 2.8, and 28/10
Step-by-step explanation: The shaded pillars/rectangles inside the squares account for the fractions. In this question, there are 10 pillars per square and 2 shaded in squares. Since there are two full squares, there are two wholes. In the third block, there are only 8 shaded. Because 8 out of ten are shaded, the fraction would be 8/10 (said as eight tenths). Overall, there are two wholes (the shaded squares) and 8/10 of a whole. Therefore, it is 2 8/10. 0.8 equals 8/10 (you can determine it by the way it is said ex: you would say “zero and ...” (and = decimal) “... eight tenths” or just “eight tenths” for .8, and 8/10 is said the same way). Since 2.8 and 2 8/10 are equal, 2.8 would also be an answer. 28/10 would be another correct answer because the two wholes/squares each have 10 pillars. In total, there are 20 pillars for the two wholes. If the 8/10 (8 out of 10) is added, the total would be 28/10. Hope this helps!

We know that the Angle Sum of a Triangle is equal to 180°.
So, Point A + Point B +Point C = 180°

A submarine is descending to examine the seafloor 2,100 feet below the surface. It takes the submarine 2 hours to make this descent. Write an equation to represent the relationship between the submarine's elevation and time.
Another submarine’s descent can be represented as y=-240x, where y is the elevation and x is time in hours. How long will it take this submarine to make the descent?
Answer:
-1050
Step-by-step explanation:
I know the answer because descending means going down so 2100 is the big number and its negative to if you do -2100 divided by 2 then you will get -1050.
It would take the submarine 8.75 hours to make the descent of 2100 feet.
Linear equationA linear equation is in the form:
y = mx + b
where m is the rate of change, y, x are variables, and b is the y intercept.
Let y represent the level of the submarine after x hours.
It takes the submarine 2 hours to make a descent of 2100 feet, hence:
y = mx
-2100 = 2m
m = -1050
y = -1050x
Given the equation y = -240x, for 2100 feet descent:
-2100 = -240x
x = 8.75 hours
It would take the submarine 8.75 hours to make the descent of 2100 feet.

early Christianity
decline and fall of the roman empire
development of the Byzantine Empire
Charlemagne's empire
Viking invasions
feudal Europe
Answer:
Step-by-step explanation:
Christianity developed in Judea in the mid-first century CE, based first on the teachings of Jesus and later on the writings and missionary work of Paul of Tarsus.
Originally, Christianity was a small, unorganized sect that promised personal salvation after death. Salvation was possible through belief in Jesus as the son of God—the same God the Jews believed in. Early Christians debated whether they should only preach to Jews, or if non-Jews could become Christians, too. Eventually, Christianity gained followers not only from Jewish communities but from throughout the Roman world.
In the decades after Jesus's death, the Apostle Paul wrote many letters that are now part of the New Testament of the Christian Bible. Paul was a Roman citizen and sent these letters to small communities of Christians living throughout the Roman Empire. The letters show us that Paul and his fellow Christians were still figuring out exactly what being a Christian meant. Issues related to the exact relationship between Judaism and Christianity, and between Christianity and the Roman government, were prominent topics of discussion.
Judaism had received the status of a legal religion in the Roman Empire with formal protections. Although Christianity developed out of Jewish traditions, it had no such legal protections. Christians were occasionally persecuted—formally punished—for their beliefs during the first two centuries CE. But the Roman state’s official position was generally to ignore Christians unless they clearly challenged imperial authority.
Rome becomes Christian
In 313 CE, the emperor Constantine issued the Edict of Milan, which granted Christianity—as well as most other religions—legal status. While this was an important development in the history of Christianity, it was not a total replacement of traditional Roman beliefs with Christianity.
In 325, Constantine called the Council of Nicaea, which was a gathering of Christian leaders to determine the formal—or orthodox—beliefs of Christianity. The result of this council was the Nicene Creed, which laid out the agreed upon beliefs of the council.
In 380 CE, the emperor Theodosius issued the Edict of Thessalonica, which made Christianity, specifically Nicene Christianity, the official religion of the Roman Empire. Most other Christian sects were deemed heretical, lost their legal status, and had their properties confiscated by the Roman state.
The Roman Empire did not become Christianized overnight. Roman religious beliefs changed slowly over time. At the time the Western Roman Empire fell in 476 CE, Christianity was still spreading. It is also important to remember that Christianity itself did not appear suddenly or fully-formed. Christianity grew out of Jewish traditions and was shaped by Roman cultural and political structures for several centuries.
To take one lasting example, the head of the Roman Catholic Church—the Pope—takes his title from the old Roman office of pontifex maximus—the high priest. Roman culture was not wholly replaced, but was often repurposed as it came into contact with other peoples and cultures.
Christianity was deeply influenced by both Judaism and Roman cultural institutions. We can't fully understand the development of the Christian religion without putting it into these contexts!

Answer:
A) r = -3
Step-by-step explanation:
4(-3) = -12
(-12 + 4) = -8
2(-8) = -16
-16 = -16
Making it true
Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅

15 = 12
500 = x
Cross multiply
15x = 12 × 500
Divide both sides by 15
\(\frac{15x}{15}\) = \(\frac{12 * 500}{15}\) (* means multiplication if you do not know)
