A student knows the mass of one of the reactants of a chemical reaction and wants to calculate the mass of one of the products of the reaction. which process should the student follow?
There are different ways to calculate math. What the student is to do in the above scenario are:
To Multiply the mass of the reactant by its molar mass to find the number of moles of the reactant. Use the chemical equation to find the number of moles of the product. Divide the number of moles of the product by its molar mass to find the mass of the product.
What is the mass of reactant?The law of conservation of mass is one that states that in form of chemical reaction, the total mass of reactants is known and regarded as equal to the total mass of products.
The steps in mass calculations are mass = moles × molar mass
Calculate moles = mass(Mg) ÷ molar mass, moles.

Evaluate the indefinite integral as an infinite series. arctan(x2) dx
The indefinite integral expressed as an infinite series is;
[tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]
How to find indefinite integral?We will first have to look for the Maclaurin series of arctan(x).
We'll recall that from online tables of integral, this Maclaurin series of arctan(x) will have the general formula;
[tex]arctan(x) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{x^{2n + 1} }{2n + 1}[/tex]
When we apply that general Maclaurin series of arctan(x) to our question of arctan(x²), we have the expression as;
[tex]arctan(x^{2} ) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x^2)^{2n + 1} }{2n + 1}[/tex]
⇒ [tex]= \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1}[/tex]
We now integrate the expression that we got above in the following manner to get;
[tex]\int\limitsarctan(x^{2} ) = \int\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1} dx[/tex]
⇒ [tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]
Thus, that expression gives us the indefinite integral of arctan(x²) as an infinite series.

A computer’s memory is composed of 8k words of 32 bits each. how many total bytes in memory?
The number of total bytes in memory is 32,000 bytes.
How many total bytes in memory?
We know that the memory is composed of 8k (or 8,000) words of 32 bits each.
To get the total memory, we just need to take the product between the number of words and the memory that each has.
This will give:
8,000*(32 bits) = 256,000 bits.
But we want this in bytes so we need to change the units, remember that:
1 bit = 0.125 byte.
Then we have:
256,000 bits = 256,000*( 0.125 byte) = 32,000 bytes.
The memory has 32,000 bytes in total.

Suppose the government in this economy decides to decrease government purchases by $250 billion. the decrease in government purchases will lead to a decrease in income, generating an initial change in consumption equal to . this decreases income yet again, causing a second change in consumption equal to . the total change in demand resulting from the initial change in government spending is .
When the government decides to decrease government purchases by $250 billion, this will lead to a $175 billion decrease in income.
How to calculate the decrease in income?From the information, the government decides to decrease government purchases by $250 billion. The decrease in income will be:
= $250 × 0.7
= $175 billion
This decrease in income yet again will cause a second change in consumption equal to:
= $175 × 0.7
= $122.5 billion
The total change in demand resulting from the initial change in government spending will be:
= $250 × (1/30%)

Answer:
So I turned homeschool not too long ago and you do need to the the SAT/ACT depending on which community college it is? If the high school or college offer ACT then the test you most likely need to take is the ACT. But if the test they offer is SAT then you should take that. Taking both of the SAT and ACT would only do better on your resume/aplication so it's really up to you. I plan to take both if I have the time. But I heard most people take the ACT. You should check what your community usually offer.

Explanation:
Answer: college admissions is handled very similarly for homeschoolers as it is for traditionally schooled students. In fact, many admissions offices actively seek out homeschoolers. Admissions officers evaluate each student within the context of his/her own background and the opportunities they've had. There are, however, a few differences regarding how homeschoolers submit certain application materials. As a homeschooled student, your parent or primary teacher is responsible for creating your high school transcript and for sending it to your colleges. Parents have a few different options for going about this:
1. Working under an umbrella school that produces official transcripts and diplomas
2. Creating their own transcript and diploma
3. Enlisting a service that specializes in transcript and diploma creation
4. Joining a homeschool group that produces professional transcripts and diplomas
Explanation:
Your transcript should include all of the following information:
Your name, the name of your homeschool (if applicable), address, and phone number
Your high school course list ordered by year (grades 9-12)
The institution where each class was taken (i.e. homeschool, online institution, community college)
The grade scale being used in your homeschool
Your overall GPA
Credits given per course (listed per semester and per year)
Expected graduation date
Parent signature with a date
Homeschoolers do not need a GED or a diploma to apply to college or qualify for financial aid; you just have to declare that your homeschool education meets state law requirements. Most homeschooled students choose not to take the GED if they have valid transcripts, as colleges will place the most emphasis on your transcript and standardized test scores. If you’re homeschooled through an online academy, virtual school, or organized homeschool program then they will award your diploma according to their own standards. If you’re homeschooled independently by your parents, then your parents have the option of issuing you a diploma if your transcripts indicate you’ve met the basic state requirements for graduation. When filling out the FAFSA, be sure to check “homeschooled” when it asks for your high school completion status. Even if your homeschool is administered through an umbrella organization, you should still check “homeschooled” instead of “high school diploma” to avoid any delays in the processing of your application.
