Alisha is correct; one should apply the quotient of powers rule by subtracting the exponents of the numerator and the denominator before cubing the expression. The simplified form is then found by raising the result to the third power, multiplying the exponents by three.
Explanation:Between Tyrone's and Alisha's claims, Alisha's approach is correct. The expression to simplify is ((m2n-3)/(m6n-1))3. According to the rules for dealing with exponents, when you have a fraction being raised to a power, you apply the quotient of powers rule before cubing the entire expression. This means that you first subtract the exponents within the numerator and the denominator before raising the simplified result to the third power.

In a train yard, there are 6 flatcars, 7 boxcars, and 3 livestock cars. A train is made up of 9 cars.
Which would you use to find the number of ways the train could be made up?
Answer:
The answer is A on edge
Step-by-step explanation:
The number of ways the train could be made up are 4,151,347,200.
What is permutation?A permutation of a set is an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.
Now the given cars are 6 flatcars, 7 boxcars, and 3 livestock cars.
So the total number of cars, n = 6 + 7 + 3
= 16
Now, a train is made up of 9 cars,
Therefore, r = 9
Hence the required number of ways the train could be made is nPr
nPr = n!/(n-r)!
nPr = 16!/(16-9)!
nPr = 16!/7!
nPr = 16*15*14*13*12*11*10*9*8
nPr = 4,151,347,200
Hence,the number of ways the train could be made up are 4,151,347,200.

Final answer:
To calculate the 7th year rent after a 10.5% annual increase starting from an initial rent of $1200, use the formula for compound interest. The rent amounts to approximately $2277.60 for the 7th year.
Explanation:
Calculating Future Rent Increase
To calculate the rent of the apartment during the 7th year after a consistent annual increase, we need to apply the percentage increase formula within a compound interest framework:
Rentₙ = Rent₀ × (1 + rate)ⁿ
Where Rentₙ is the rent after n years, Rent₀ is the initial rent, rate is the annual increase rate in decimal form, and n is the number of years.
For an initial rent of $1200 with a 10.5% increase per year:
Rent for the 7th year will be calculated as follows:
Rent₀ = $1200
rate = 10.5% or 0.105 in decimal form
n = 6 (since we are starting from year 1 to year 7)
Using the formula:
Rent₇ = $1200 × (1 + 0.105)⁶
Upon calculation, the rent for the 7th year is approximately:
Rent₇ = $1200 × (1.105)⁶ ≈ $1200 × 1.898 = $2277.60
Thus, the rent of the apartment during the 7th year of living there would be approximately $2277.60
A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the square? Use 3.14 for π, and round your answer to the nearest hundredth.
Answer:
38.47 square units
Step-by-step explanation:
All we have to do is first find the perimeter of the square (which is equal to the circumference of the circle), then find the radius of the circle and finally the area of the circle.
The square has a side that measures 5.5 units.
The perimeter of a square is given as:
P = 4L
where L = length of side of the square
Therefore, the perimeter of the square is:
P = 4 * 5.5 = 22 units.
This means that the circumference of the circle is 22 units.
The circumference of a circle is given as:
C = 2πR
and the area of a circle is given as:
[tex]A = \pi R^2[/tex]
where R = radius
Therefore:
22 = 2πR
=> R = 22 / (2 * 3.14)
R = 22 / (6.28)
R = 3.50 units
The area is therefore:
[tex]A = \pi * 3.50^2[/tex]
A = 38.47 square units
The area of the circle is 38.47 square units.
The area of the circle is approximately 15.64 square units, calculated using the perimeter of the square and circle formulas.
To find the area of the circle with a circumference equal to the perimeter of the square, we'll first calculate the perimeter of the square using its side length. Then, we'll use the circumference formula to find the radius of the circle. Finally, we'll use the area formula for a circle to find the area.
Step 1:
Calculate the perimeter of the square.
Perimeter of square = 4 * side length = [tex]\(4 \times 5.5 = 22\)[/tex] units.
Step 2:
Set up the equation for the circumference of the circle.
Circumference of circle =[tex]\(2\pi \times\)[/tex] radius = Perimeter of square.
Step 3:
Solve for the radius.
[tex]\[2\pi \times \text{radius} = 22\][/tex]
[tex]\[\text{radius} = \frac{22}{2\pi}\][/tex]
Step 4:
Use the radius to find the area of the circle.
Area of circle = [tex]\(\pi \times \text{radius}^2\)[/tex]
Step 5:
Substitute the value of the radius and calculate.
[tex]\[Area = 3.14 \times \left(\frac{22}{2\pi}\right)^2\][/tex]
[tex]\[Area \approx 15.64\][/tex]
The area of the circle with a circumference equal to the perimeter of the square is approximately [tex]\(15.64\)[/tex] square units.

Answer: The height of the monitor is 12 inches.
Step-by-step explanation:
First, you need to acknowledge the Pythagorean Theorum,
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
You already have the c and the b , so you just have to plug them in to find a!
This is what it looks like when you substitute:
a² + 16² = 20²
Then, simplify.
a² + 256 = 400
Now, to isolate the variable, you have to move 256 to the other side. This, of course, means it changes from a positive to a negative number.
a² = 400 - 256
a² = 144
Now, you have to remove the square root from a. But, don’t forget, what you do to one side, you have to do to the other side. So, your equation will now look like this:
√a² = √144
The square root of a squared is obviously just a! And the square root of 144 is 12. Therefore, we now know that:
a = 12
So, the height of the monitor was 12 inches.
What is the data point that is the farthest from other data points when the box plot is NOT symmetrical?
A. Median
B. Outliner
C. Greatest Point
need an answer ASAP
Answer: B. Outlier
Step-by-step explanation:
An outlier is an extremely large or extremely small data value in a data set such that it appears far from the other data points when we plot data points on scatter plot or box plot.
Thus, the data point that is the farthest from other data points when the box plot is NOT symmetrical is Outlier.
Its presence affects the value of mean directly. So when a data set have outliers , we prefer Median(Mid value of a data set) as the best measure of central tendency because existence of outliers does not effect Median .
Hence, the correct option is B. Outlier.

Sandra bought a boat for $28,800. According to her insurance company the value of the boat depreciates 7% each year. What will the value of the boat be x years after she purchased it?
We have been given that Sandra bought a boat for $28,800. According to her insurance company the value of the boat depreciates 7% each year. We are asked to find the value of the boat x years after Sandra purchased it.
We will use exponential decay formula to solve our given problem.
An exponential decay function is in form [tex]y=a(1-r)^x[/tex], where,
y = Final amount,
a = Initial amount,
r = Decay rate in decimal form,
x = Time.
Let us convert 7% into decimal form.
[tex]7\%=\frac{7}{100}=0.07[/tex]
Initial value of car is $28,800, so our function will be:
[tex]y=$28,800(1-0.07)^x[/tex]
[tex]y=$28,800(0.93)^x[/tex]
Therefore, the value of boat after x years would be [tex]y=$28,800(0.93)^x[/tex].

Find the slope of the line that passes through (57, -27) and (-19, -34)
Answer:
10.86
Step-by-step explanation:
m = Y2 - Y1 / X2 - X1 = -19 -57 / -34 +27 = -76 / -7 = 10.86
Answer:
y=7/76x-129/4
Step-by-step explanation:
I'm going to assume you want this in slope intercept form.
The equation of a line is equal to y = mx+b
Where m is the slope and b is the y-intercept.
The slope of a line is a measure of how steep the line is.
For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:
y2-y1/x2-x1
So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (57,-27), point #1, so the x and y numbers given will be called x1 and y1, and the second point will be x2 and y2.
So we just plug in the numbers, and find the slope to be 7/76.
What about b(the y-intercept), I can already hear you typing. Well, to do that, you plug in the coordinates of the points given and solve for b.
And there you have it:
y=7/76x-129/4 is the equation of the line.

Find a value of 3a+4b when a=17 and b=9. Then use the formula v=u+at when the initial velocity is 3 m/s, the acceleration is 1.5m/s squared and the time is 7 seconds.
Final answer:
The value of 3a+4b is 87 when a=17 and b=9. Using the kinematics equation v=u+at, the final velocity is calculated as 13.5 m/s given the initial conditions provided.
Explanation:
To find the value of 3a+4b when a=17 and b=9, we substitute the given values into the expression:
3(17) + 4(9) = 51 + 36 = 87.
Thus, the value of 3a+4b is 87.
The next part of the question involves using the kinematics equation v = u + at to find the final velocity v. We are given an initial velocity u = 3 m/s, an acceleration a = 1.5 m/s2, and a time t = 7 seconds. Plugging the values into the formula gives us:
v = 3 m/s + (1.5 m/s2)(7 s) = 3 m/s + 10.5 m/s = 13.5 m/s.
The final velocity after 7 seconds is therefore 13.5 m/s.

scale factor is 6/5 is the dilation an enlargement, reduction or congruence transformation? *
Answer:
Enlargement transformation
Step-by-step explanation:
A dilation is a transformation which produces an image of the same shape as the original, but may/may not be of the same size. A dilation could be an enlargement, reduction or a congruence.
The following rule applies(given the scale factor k)
If k > 1, there is an enlargement. If 0 < k < 1, there is a reduction. If k = 1, there is a congruence.therefore, since k=6/5=1.2>1, there is an enlargement transformation
Final answer:
When the scale factor is 6/5, it indicates that each dimension of the original figure is increased to achieve the new figure's dimensions, marking this transformation as an enlargement because the scale factor is greater than 1.
Explanation:
If a scale factor is 6/5, this means every dimension in the original figure is multiplied by 6/5 to get the dimensions of the new figure. Since the scale factor is greater than 1, each dimension of the original figure is increased to get the dimensions of the new figure. Therefore, this type of dilation is an enlargement, not a reduction or congruence transformation. An enlargement increases the size of an object while keeping its shape the same. In contrast, a reduction would mean the scale factor is less than 1, and a congruence transformation, which includes transformations like translation, rotation, and reflection, does not change the size at all.
PLEASE HELP!! Compare & Contrast how Completing the Square is used to Convert a quadratic function to vertex form with how it is used to Solve a quadratic equation.
Answer:
Step-by-step explanation:
Given a general quadratic formula given as ax²bx+c = 0
To generate the general formula to solve the quadratic equation, we can use the completing the square method as shown;
Step 1:
Bringing c to the other side
ax²+bx = -c
Dividing through by coefficient of x² which is 'a' will give:
x²+(b/a)x = -c/a
- Completing the square at the left hand side of the equation by adding the square of half the coefficient x i.e (b/2a)² and adding it to both sides of the equation we have:
x²+(b/a)x+(b/2a)² = -c/a+(b/2a)²
(x+b/2a)² = -c/a+(b/2a)²
(x+b/2a)² = -c/a + b²/4a²
- Taking the square root of both sides
√(x+b/2a)² = ±√-c/a + b²/√4a²
x+b/2a = ±√(-4ac+b²)/√4a²
x+b/2a =±√b²-4ac/2a
- Taking b/2a to the other side
x = -b/2a±√√b²-4ac/2a
Taking the LCM:
x = {-b±√b²-4ac}/2a
This gives the vertex form with how it is used to Solve a quadratic equation.

Regardless of the diameter, the radius is half the diameter. For this sphere, it is 5/2 m = 2.5 m.
__
The height of the sphere is equal to its diameter, so is 2r. The volume of a cylinder with radius r and height 2r is ...
V = πr²h = πr²(2r) = 2πr³
The volume of a sphere with radius r is ...
V = 4/3πr³
Then the ratio of sphere volume to cylinder volume is ...
(4/3πr³)/(2πr³) = (4/3)/2 = 2/3
The sphere volume is 2/3 that of a cylinder with the same radius and height.
