You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

whats the area of the shape?
Answers
Answer:
28 united squared
Step-by-step explanation:
Let us pretend this is a regular rectangle.
The area would be 32, however the bottom is cut off.
If we draw it in, we can see the base and height are 2 and 4 respectively.
We can then calculate this triangle which is (4*2)/2 = 4
We then subtract this from the rectangle of size 32, resulting in 28 units squared

how can you find the simplest form of 100/1,000?
Answers
Answer:
0.1
Step-by-step explanation:
To figure this out, since the numbers are pretty much the same with a 1 and 0's, we can take the 100 and subtract the number of zeros in 1,000, which is 3. So, take the decimal point which is by the last 0 on the 100 and move it 3 times because there are 3 zeros in 1,000:
100.0 (This is where the decimal would be in one hundred)
10.0 (This is one decimal point over)
1.0 (This is two decimal points over)
0.1 (This is three decimal points over)

The cost of a trail mix at the grocery store is normally $12 per pound but now the price has increased by 30%. What is the price per pound of trail mix now that the price has increased?
Answers
Answer:
15.6
Step-by-step explanation:
The price of trail mix has increased by $12 * 30/100 = $<<12*30/100=3.6>>3.6.
So the price per pound of trail mix now is $12 + $3.6 = $<<12+3.6=15.6>>15.6.
The required new price of the trail mix is $15.6 .
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
The normal cost of trail mix at the grocery store = $12 per pound.
Als0, the price of the trail mix increased by 30%.
To find the price of trail mix after increasing the price,
Use percentage property,
Let the initial price was 100 %
So after increasing 30%, the new price becomes 130%.
The new price = 12 x 130% = 12 x 130 / 100 = 1560/100 = 15.6
The increased price of the trail mix is $15.6.

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

please help with surface area of cylinder
Answers
Answer:
Step-by-step explanation:
The surface area of a cylinder can be calculated using the formula:
SA = 2πr^2 + 2πrh
where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is approximately equal to 3.14.
Looking at the given diagram, we can see that the height of the cylinder is 10 cm and the radius of the base is 6 cm.
So, substituting these values into the formula:
SA = 2π(6)^2 + 2π(6)(10)
SA = 2π(36) + 2π(60)
SA = 72π + 120π
SA = 192π
Using a calculator, we can approximate this value to:
SA ≈ 602.88 cm^2
Therefore, the surface area of the cylinder is approximately 602.88 cm^2.

17.3+v=22.32 what is the value of v
Answers
Answer:
5.02
Step-by-step explanation:
Reverse operation - 22.32-17.3=5.02
To check your work, you would do
17.3+5.02 which ends up with 22.32
Answer:
\(v = 5.02\)
Step-by-step explanation:
1) Subtract 17.3 from both sides.
\(v = 22.32 - 17.3\)
2) Simplify 22.32 - 17.3 to 5.02.
\(v = 5.02\)
Therefor, the answer is v = 5.02.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
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.

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.
