(Factorise) 3m(Square) - 16mn - 12n (Square)
Answer:
(m - 6n)(3m + 2n)
Step-by-step explanation:
Given
3m² - 16mn - 12n²
Consider the factors of the product of the coefficient of the m² term and the n² term which sum to give the coefficient of the mn term
product = 3 × - 12 = - 36 and sum = - 16
The factors are - 18 and + 2
Use these factors to split the mn term
3m² - 18mn + 2mn - 12n² ( factor the first/second and third/fourth terms )
= 3m(m - 6n) + 2n(m - 6n) ← factor out (m - 6n) from each term
= (m - 6n)(3m + 2n)

Answer:
{196, 256, 484}
Step-by-step explanation:
14² = 196;
16² = 256;
19² = 361; 390 lies between 361 and 400, and is thus NOT a perfect square;
20² = 400;
22² = 484
564 lies between the two perfect squares 23² and 24², but is itself NOT a perfect square.
Thus, the perfect squares are {196, 256, 484}
The perfect squares out of the numbers 196, 256, 390, 484, 564 are 196, 256, and 484. A perfect square is a number that can be expressed as an integer multiplied by itself.

State the various transformations applied to the base function ƒ(x) = x^2 to obtain a graph of the function g(x) = −2[(x − 1)^2 + 3].
(A) A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 2 units to the right, and a vertical shift downward of 6 units.
(B) A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
(C) A reflection about the y-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
(D) A reflection about the y-axis, a vertical stretch by a factor of 2, a horizontal shift of 2 units to the right, and a vertical shift downward of 6 units.
Answer: Option B
A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
Step-by-step explanation:
If the graph of the function [tex]g(x)=cf(h-h) +b[/tex] represents the transformations made to the graph of [tex]y= f(x)[/tex] then, by definition:
If [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor c.
If [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor c
If [tex]c <0[/tex] then the graph is reflected on the x axis.
If [tex]b> 0[/tex] the graph moves vertically upwards b units.
If [tex]b <0[/tex] the graph moves vertically down b units
If [tex]h> 0[/tex] then the graph of f(x) moves horizontally h units to the left
If [tex]h <0[/tex] then the graph of f(x) moves horizontally h units to the right
In this problem we have the function [tex]g(x) = -2((x - 1)^2 + 3)[/tex] and our parent function is [tex]f(x) = x^2[/tex]
therefore it is true that [tex]c =-2<0[/tex] and [tex]b =-6 <0[/tex] and [tex]h=-1<0[/tex]
Therefore the graph is reflected on the x axis, stretched vertically by a factor 2. The graph of f(x) moves horizontally 1 units to the right and shift downward of 6 units.
The answer is (B) A reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift downward of 6 units.
Final answer:
The correct transformations from f(x) = x² to g(x) = −2[(x − 1)² + 3] are a reflection about the x-axis, a vertical stretch by 2, a horizontal shift 1 unit to the right, and a vertical shift 3 units upwards, which is option (B) in the list provided.
Explanation:
The function g(x) = −2[(x − 1)² + 3] has undergone several transformations from the base function f(x) = x^2. These transformations include a reflection about the x-axis due to the negative sign in front of the equation, indicating that a flip has happened vertically. A vertical stretch by a factor of 2 is also evident from the coefficient 2 before the parenthesis.
The term (x - 1) inside the parenthesis indicates a horizontal shift of 1 unit to the right since we subtract from x to move the graph to the right. Lastly, the +3 at the end of the equation signifies a vertical shift of 3 units upwards, which is a change in the y-value of every point on the graph.
Therefore, the correct sequence of transformations to obtain g(x) from f(x) is: a reflection about the x-axis, a vertical stretch by a factor of 2, a horizontal shift of 1 unit to the right, and a vertical shift of 3 units upwards, which corresponds to option (B) provided by the student.
What is 726,034 rounded to the nearest ten thousand
Answer:730000
Step-by-step explanation:
Follow below steps;
To round the number 726,034 to the nearest ten thousand, we must look at the thousands digit, which is 2. Since 2 is less than 5, we do not round up, and thus, leave the ten thousands place as it is.
The number 726,034 rounded to the nearest ten thousand is 720,000. We can see that the thousand's digit is less than 5, so we round down. This process aligns with the rounding rule stating that if the number you are rounding is followed by 0, 1, 2, 3, or 4, you round the number down.

What is the factored form of x^12y^18+1?
Answer:
[tex](x^{4}y^{6}+1)(x^{8}y^{12}-x^{4}y^{6}+1)[/tex].
Step-by-step explanation:
We want to expand: [tex]x^{12}y^{18}+1[/tex].
We can rewrite this as the sum of two cubes.
[tex](x^{4})^3(y^{6})^3+1=(x^{4}y^{6})^3+1^3[/tex].
Recall and use the sum of cubes identity: [tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]
By comparing our newly rewritten expression to this identity, we have [tex]a=x^4y^6[/tex] and [tex]b=1[/tex].
We substitute into the identity to get:
[tex](x^{4}y^{6})^3+1^3=[x^{4}y^{6}+1][(x^{4}y^{6})^2-(x^{4}y^{6})(1)+1^2][/tex].
We now use this rule of exponents :[tex](a^m)^n=a^{mn}[/tex] to get;
[tex](x^{4}y^{6}+1)(x^{8}y^{12}-x^{4}y^{6}+1)[/tex].

−10
−x = 4 − 3x + 6
Move the -3x to the other side and simplify 4+6.
2x= 10
Divide both sides by 2
x=5.
Answer: First option.
Step-by-step explanation:
Given the equation [tex]-x = 4- 3x + 6[/tex], you need to solve for the variable "x" to find its value.
Add the like terms on the right side of the equation:
[tex]-x = 10-3x [/tex]
Now you need to subtract 10 from both sides of the equation:
[tex]-x-10 = 10- 3x -10[/tex]
[tex]-x-10 =- 3x[/tex]
The next step is to add "x" to both sides of the equation:
[tex]-x-10+x = - 3x +x[/tex]
[tex]-10 = - 2x[/tex]
And finally, divide both side by -2:
[tex]\frac{-10}{-2}=\frac{-2x}{-2}\\\\x=5[/tex]
A company makes glass lawn ornaments with a radius of 9 inches. The glass to make the balls costs the company $0.03 per square inch. To the nearest cent, how much does the company pay for the glass to create one ornament?
Answer:

A. −1, 1, 2
B. −2, −1, 1
C. −3, −1, 1
D. −1, 1, 3
Answer:
The zeroes of the function are -3 , -1 , 1 ⇒ 3rd answer
Step-by-step explanation:
* Lets explain the meaning of the zeroes of the function
- The zeroes of the function are the values of x when f(x) = 0
- That means the coordinates of the intersection points between the
curve and the x-axis
- Ex: If the graph of f(x) intersects the x-axis at points (p , 0) , (q , 0) ,
(r , 0) then the zeroes of f(x) are p , q , r
* Lets solve the problem
- The graph starts at the bottom left
- It continues up through the x-axis at negative three
- That means it intersects the x-axis at point (-3 , 0)
∴ The first zero of the function is -3
- It goes to a maximum around y equals three
- It goes back down through the x-axis at negative one
- That means it intersects the x-axis again at point (-1 , 0)
∴ The second zero of the function is -1
- It goes to a minimum around y equals negative one
- It goes back up through the x-axis at one
- That means it intersects the x-axis again at point (1 , 0)
∴ The third zero of the function is 1
∴ The function has three zeroes -3 , -1 , 1
* The zeroes of the function are -3 , -1 , 1

The point slope form of the equation of the line that passes through (-5-1) and (10.-7) is
standard form of the equation for this line?
Answer:
The standard form of the equation for this line can be:
l: 2x + 5y = -15.
Step-by-step explanation:
Start by finding the slope of this line.
For a line that goes through the two points [tex](x_0, y_0)[/tex] and [tex](x_1, y_1)[/tex],
[tex]\displaystyle \text{Slope} = \frac{y_{1} - y_{0}}{x_{1} - x_{0}}[/tex].
For this line,
[tex]\displaystyle \text{Slope} = \frac{(-1) - (-7)}{(-5) - 10} = -\frac{2}{5}[/tex].
Find the slope-point form of this line's equation using
[tex]\displaystyle \text{Slope} = -\frac{2}{5}[/tex], andThe point [tex](-5, -1)[/tex] (using the point [tex](10, -7)[/tex] should also work.)The slope-point form of the equation of a line
with slope [tex]m[/tex] andpoint [tex](x_{0}, y_{0})[/tex]should be [tex]l:\; y - y_{0} = m(x - x_0)[/tex].
For this line,
[tex]\displaystyle m = -\frac{2}{5}[/tex], and[tex]x_0 = -5[/tex], and[tex]y_0 = -1[/tex].The equation in slope-point form will be
[tex]\displaystyle l:\; y - (-1) = -\frac{2}{5}(x - (-5))[/tex].
The standard form of the equation of a line in a cartesian plane is
[tex]l: \; ax + by = c[/tex]
where
[tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are integers. [tex]a \ge 0[/tex].
Multiply both sides of the slope-point form equation of this line by [tex]5[/tex]:
[tex]l:\; 5 y + 5 = -2x -10[/tex].
Add [tex](2x-5)[/tex] to both sides of the equation:
[tex]l: \; 2x + 5y = -15[/tex].
Therefore, the equation of this line in standard form is [tex]l: \; 2x + 5y = -15[/tex].

[tex]2x^{2} + 9x - 18 = 0[/tex]
Answer:
x = - 6, x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Assuming you require the solution to the equation
Given
2x² + 9x - 18 = 0
To factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 18 = - 36 and sum = + 9
The factors are + 12 and - 3
Use these factors to split the x- term
2x² + 12x - 3x - 18 = 0 ( factor the first/second and third/fourth terms )
2x(x + 6) - 3(x + 6) = 0 ← factor out (x + 6) from each term
(x + 6)(2x - 3) = 0
Equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]
what is the inverse of f(x) = -5x-4

Step-by-step explanation:
The question has provided an expression for the function [tex]f(x)[/tex] and is asking for its inverse, [tex]f^{-1}(x)[/tex].
Based on the definition of inverse functions,
[tex]f(f^{-1}(x)) = x[/tex].
Let [tex]y = f^{-1}(x)[/tex].
[tex]f(y) = x[/tex].
[tex]-5 y - 4= x[/tex].

What type of number is 25,747. whole number, integer, rational or irrational
Answer:
25747 is all you mentioned except irrational
Step-by-step explanation:
Whole numbers are counting numbers or also 0. If you can count to it and you can but no one wants to in this cases because that's a big number, then it is a whole number for sure. So 25747 is a whole number which means it is also an integer and also a rational number. It is definitely not irrational.
25,747 is a positive whole number and thus is classified as an integer. It is also a rational number, but it is not an irrational number. Therefore, 25,747 is both a whole number and a rational number.
The number 25,747 is an example of a positive whole number and can also be classified as an integer. In mathematics, an integer is defined as any whole number without a fractional or decimal component, which can be positive, negative, or zero. Since 25,747 is a whole number greater than zero, it is specifically a positive integer.
A rational number is a number that can be expressed as the ratio of two integers, such as fractions or any number that has a finite or repeating decimal expansion. Clearly, 25,747 qualifies as a rational number since it can be written as 25,747/1.
An irrational number, on the other hand, cannot be expressed as a simple fraction - examples include π (pi) and √2 (the square root of 2), both of which have non-repeating, non-terminating decimal expansions. Therefore, 25,747 is not irrational.
