The polynomial (2m + 2n)6 = 12m + 12n.
For the long division, the quotient is x - 2, the remainder is 6, and the dividend can be written as (x - 2)(x² - 4x + 3) + 6.
How to divide polynomials?To expand the expression (2m + 2n)6, using the distributive property of multiplication over addition:
(2m + 2n)6 = 2m(6) + 2n(6)
Simplifying further, evaluate the products:
= 12m + 12n
Therefore, (2m + 2n)6 = 12m + 12n.
Using long division to divide the polynomial x³ - 6x² + 11x - 6 by the polynomial x² - 4x + 3. The steps are as follows:
x - 2
------------------
x² - 4x + 3 | x³ - 6x² + 11x - 6
- (x³ - 4x² + 3x)
- 2x² + 8x
- 2x² + 8x - 6
+ 6
Therefore, x³ - 6x² + 11x - 6 = (x - 2)(x² - 4x + 3) + 6.
So the quotient is x - 2, the remainder is 6, and the dividend can be written as (x - 2)(x² - 4x + 3) + 6.

Use the properties of exponents to create an equivalent expression for the given expression
shown below with no variables in the denominator.
(64x²)-^-1/6(32x^5)^-2/5
Answers
a^m * a^n = a^(m+n)
(a^m)^n = a^(mn)
(a*b)^m = a^m * b^m
a^(-m) = 1/a^m
Using these properties, we can simplify the given expression as follows:
(64x²)^(-1/6) * (32x^5)^(-2/5)
= (2^6 * x^2)^(-1/6) * (2^5 * 2x^5)^(-2/5)
= 2^(-6/6) * x^(-2/6) * 2^(-2/5) * (2x^5)^(-2/5)
= 2^(-1) * x^(-1/3) * 2^(-2/5) * 2^(-4/5) * x^(-2)
= 2^(-9/5) * x^(-7/3)
= (1/2^(9/5)) * (1/x^(7/3))
Thus, an equivalent expression with no variables in the denominator is (1/2^(9/5)) * (1/x^(7/3)).

Answers
Answer:
AB is not a tangent. The lengths 4, 12, and 13 do not form a right triangle.
√(4^2 + 12^2) = √160, which is not equal to 13.
Answer:
No
Step-by-step explanation:
if AB is a tangent the the angle BAC = 90°
using Pythagoras' theorem
then square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
BC² = 13² = 169
AB² + AC² = 12² + 4² = 144 + 16 = 160
since BC²≠ AB² + AC²
then Δ ABC is not a right triangle so AB is not a tangent

What is an equation of the line that passes through the points (0,-8) and (4, -3)?
=00
Answers
Hello!
To find the equation of the line that passes through the points (0,-8) and (4,-3), we can use the slope-intercept form of the equation:
y = mx + b
where m is the slope of the line and b is the y-intercept.
First, find the slope (m) of the line using the formula:
m = (y2 - y1)/(x2 - x1)
where (x1, y1) = (0,-8) and (x2, y2) = (4,-3).
m = (-3 - (-8))/(4 - 0) = 5/4
Now that we have the slope (m), we can use the point-slope form of the equation to find the equation of the line:
y - y1 = m(x - x1)
where (x1, y1) = (0,-8) and m = 5/4.
y - (-8) = (5/4)(x - 0)
Simplify the equation to get the slope-intercept form:
y + 8 = (5/4)x
y = (5/4)x - 8
Therefore, the equation of the line that passes through the points (0,-8) and (4,-3) is y = (5/4)x - 8.

The solution of "quadratic-equation" , 3x² - 6x + 2 = 0 is (b) x = (3 ± √3)/3.
A "Quadratic-Equation" is defined as a second-degree polynomial equation of the form : ax² + bx + c = 0,
where x = variable, and "a", "b", and "c" are constants, with a ≠ 0.
We use the "quadratic-formula" to solve : which is ⇒ x = (-b ± √(b²-4ac))/(2a),
In the quadratic equation "3x² - 6x + 2 = 0", We get , a = 3, b = -6, and c = 2.
Substituting the values,
we get,
⇒ x = (-(-6) ± √((-6)²-4(3)(2)))/(2×3),
⇒ x = (6 ± √(36-24))/6,
⇒ x = (6 ± √12)/6,
⇒ x = (6 ± 2√3)/6,

The height and radius of a cone are each multiplied by 3.
What effect does this have on the volume of the cone?
The volume of the cone is multiplied by
Answers
If both the height and radius of a cone are multiplied by 3, the new radius and height will be 3r and 3h, respectively.
We can substitute these values into the volume formula for the new cone:
V = (1/3)π(3r)^2(3h)
Simplifying the expression gives:
V = (1/3)π(27r^2h)
V = 9πr^2h
So, the volume of the new cone is 9 times larger than the volume of the original cone.
Therefore, if both the height and radius of a cone are each multiplied by 3, the volume of the cone is multiplied by 9
How can you eliminate the y-terms in this system?
Answers
To eliminate the y-terms in this system of equations, we can multiply the second equation by 2 and add it to the first equation.
We have,
To eliminate the y-terms in this system of equations, we can multiply the second equation by 2 and add it to the first equation.
This will result in the y-terms canceling out, and we will be left with only x-terms on one side of the equation, which we can then solve for x.
So, multiplying the second equation by 2, we get:
2(3x + 4y) = 2(5)
6x + 8y = 10
Now, adding this to the first equation, we get:
4x - 8y + 6x + 8y = 20 + 10
10x = 30
Dividing both sides by 10, we get:
x = 3
Now, we can substitute this value of x back into either of the original equations to solve for y.
4x - 8y = 2
So,
4(3) - 8y = 20
12 - 8y = 20
-8y = 8
y = -1
Therefore,
The solution to the system of equations is (x, y) = (3, -1).

Determine how many liters a right circular cylindrical tank holds if it is 6 m long and 13 m in diameter.
Answers
The tank holds approximately 994,040 liters.
To solve this problem
The volume of a right circular cylinder is given by the formula:
V = πr^2h
Where
r is the radius of the cylinderh is its height π is a mathematical constant approximately equal to 3.14159The cylinder's diameter is specified as 13 m, hence the radius may be computed using the formula: r = d/2 = 13/2 = 6.5 m
The cylinder is described as having a 6 m length.
These values are substituted into the volume calculation to produce the following result:
V = π(6.5)^2(6)
V ≈ 994.04 cubic meters
Since 1 cubic meter equals 1000 liters, we can convert the volume to liters by multiplying by 1000.
V = 994.04 cubic meters x 1000 liters/cubic meter
V = 994,040 liters

Answers
a. The magnitude of earthquake 7 is 1.259 times stronger than a magnitude 6 earthquake
b. The magnitude of earthquake 9 is 1.995 times stronger than a magnitude 6 earthquake
What is the magnitude of an earthquake?The magnitude of an earthquake is given by M = 10㏒(A/A₀) where A = intensity of eartquake and A₀ = standard intensity
a. To find out how much stronger is a magnitude 7 earthquake than a magnitude 6 earthquake, we proceed as folllows.
For a magnitude of 7,
M = 7 and intensity = A'So, M = 10㏒(A'/A₀)
7 = 10㏒(A'/A₀) (1)
For a magnitude of 6,
M = 6 and intensity = A"So, M = 10㏒(A'/A₀)
6 = 10㏒(A"/A₀) (2)
Subtracting (2) from (1), we have that
7 - 6 = 10㏒(A'/A₀) - 10㏒(A"/A₀)
1 = 10㏒[(A'/A₀) ÷ (A"/A₀)]
1 = 10㏒[(A'/A")
㏒[(A'/A") = 1/10
Taking inverse logarithm, we have
(A'/A") = ¹⁰√10
= 1.259
So, it is 1.259 times stronger
b. To find out how much stronger is a magnitude 9 earthquake than a magnitude 6 earthquake, we proceed as folllows.
For a magnitude of 9,
M = 9 and intensity = A'So, M = 10㏒(A'/A₀)
9 = 10㏒(A'/A₀) (1)
For a magnitude of 6,
M = 6 and intensity = A"So, M = 10㏒(A'/A₀)
6 = 10㏒(A"/A₀) (2)
Subtracting (2) from (1), we have that
9 - 6 = 10㏒(A'/A₀) - 10㏒(A"/A₀)
3 = 10㏒[(A'/A₀) ÷ (A"/A₀)]
3 = 10㏒[(A'/A")
㏒[(A'/A") = 3/10
Taking inverse logarithm, we have
(A'/A") = 10⁰°³
= 1.259

Peter’s teacher says he may have his report card percentage based on either the mean or the median and he can drop one test score if he chooses.
84%, 71%, 64%, 90%, 75%, 44%, 98%
Which measure of center should Peter choose so he can have the highest percentage possible?
Peter should choose the mean after dropping one test score.
Peter should choose the mean without dropping one test score.
Peter should choose the median after dropping one test score.
Peter should choose the median without dropping one test score.
Answers
Answer:
A.
Step-by-step explanation:
Peter should choose to base his report card percentage on the median if he wants to have the highest percentage possible. To calculate the median, Peter would first order the scores from lowest to highest: 44%, 64%, 71%, 75%, 84%, 90%, 98%. Then, he would select the middle score as the median, which is 75%. If Peter drops his lowest score (44%), his percentage based on the median would be 80% ((64%+71%+75%+84%+90%+98%)/6). If he were to choose the mean, his percentage would also be 80%. However, since the median is not affected by extreme values like the 44% score, it is a more reliable measure of central tendency in this case.
I did this on homework b4 and got It right so this Is 100 percent right.
Answer:
Peter should choose the median after dropping one test score so he can have the highest percentage possible.
If we calculate the mean of all seven test scores, we get:
(84+71+64+90+75+44+98)/7 = 73.14%
If we calculate the median of all seven test scores, we get:
Arrange the scores in ascending order:
44, 64, 71, 75, 84, 90, 98
The median is 75.
If we drop the lowest score (44) and calculate the mean of the remaining six test scores, we get:
(84+71+64+90+75+98)/6 = 80.5%
If we drop the lowest score (44) and calculate the median of the remaining six test scores, we get:
Arrange the scores in ascending order:
64, 71, 75, 84, 90, 98
The median is 79.5%.
Therefore, Peter should choose the median after dropping one test score to have the highest possible percentage.
26). Is Δ EFG ≅ Δ HIJ?
27). What is the scale factor of Δ EFG to Δ HIJ?
28). What is the ratio of their perimeters?
29). What is the ratio of their areas?
Answers
The triangles are not congruent.
Given that, two triangles, EFG and HIJ are similar,
So,
Since, the triangles are similar, but according to the definition of similarity, two objects that are similar are not necessarily congruent,
so the Δ EFG is not congruent to Δ HIJ.
Cos 30° = HI / HJ
√3/2 = 3/HI
HI = 3.5
Therefore, the scale factor Δ EFG to Δ HIJ = EF / HI = 10/3.5 = 2/0.7
The ratio of perimeter of similar objects are same as the scale factor,
so, the ratio of their perimeters = 2/0.7
The ratio of the areas of the similar objects are the ratios of the squares of the scale factor.
So, the ratio of their areas = 4/0.49
