In this case, this function is even
Answer:
The function [tex]f(x)=x^6-x^4[/tex] is:
Even
Step-by-step explanation:
A function f(x) is even if:
f(-x)= f(x)
A function f(x) is odd if:
f(-x)= -f(x)
Here, we are given a function f(x) as:
[tex]f(x)=x^6-x^4[/tex]
[tex]f(-x)=(-x)^6-(-x)^4\\\\ =x^6-x^4\\\\=f(x)[/tex]
f(-x)=f(x)
Hence, the function [tex]f(x)=x^6-x^4[/tex] is:

An equiangular triangle can never be scalene. true or false?
The given statement "An equiangular triangle can never be scalene." is true.
What is an equiangular triangle?An equiangular triangle is a triangle that has three equal angles.
What is a scalene triangle?A scalene triangle is a triangle that has three unequal sides.
Therefore, a scalene triangle has three different angles.
Therefore, an equiangular triangle and scalene triangle are two completely different triangles.
Hence, an equiangular triangle can never be a scalene triangle.

Find two consecutive even integers such that the smaller added to threetimes the larger gives a sum of 30.
The two consecutive even integers that satisfy the given condition are 6 and 8. When the smaller one (6) is added to three times the larger one (8), the sum is 30.
The student has asked for help in finding two consecutive even integers such that the smaller added to three times the larger gives a sum of 30. To solve this, let's designate the smaller even integer as x. Since the numbers are consecutive even integers, the next integer will be x + 2.
The equation based on the problem statement will look like this:
x + 3(x + 2) = 30
Expanding the equation gives:
x + 3x + 6 = 30
Combining like terms:
4x + 6 = 30
Subtracting 6 from both sides:
4x = 24
And dividing by 4:
x = 6
Now, the two consecutive even integers can be determined:
The smaller integer is 6, and the larger integer is 6 + 2, which equals 8. Therefore, the two integers are 6 and 8, and if we check:
6 + 3(8) = 6 + 24 = 30, which matches the required sum.

What is the product of -9(5-2x)
The product of -9(5-2x) is found by multiplying -9 by each term inside the parentheses resulting in -45 + 18x.
Explanation:The product of -9(5-2x) is found by distributing the -9 to both terms inside the parentheses. Following the rules of multiplication, when a negative number multiplies a positive number, the result is negative, and when a negative number multiplies a negative number, the result is positive. Hence:
-9 x 5 = -45
and
-9 x -2x = 18x.
Combining these results, we get the final expression:
-45 + 18x
Keep in mind that when simplifying expressions or performing multiplication, we need to adhere to the rules for multiplication of numbers with different signs, as described earlier.
Final answer:
The product of -9(5-2x) is calculated by using the distributive property to multiply -9 by each term inside the parentheses, yielding 18x - 45.
Explanation:
The product of -9(5-2x) can be found by applying the distributive property of multiplication over subtraction. This property states that you multiply the term outside the parentheses by each term inside the parentheses. Here are the steps:
Multiply -9 by the first term inside the parentheses (5), which is -45.
Multiply -9 by the second term inside the parentheses (-2x), which gives us +18x (note that a negative multiplied by a negative gives a positive).
Combine these two products to get the final result, -45 + 18x, or 18x - 45.
This demonstrates the rules of multiplication where multiplying two numbers with opposite signs results in a negative product, and multiplying two numbers with the same sign results in a positive product.
Find the area of the shaded portion in the square (assuming the center point of each arc is the corresponding central point of the line and the arcs intersect at the center point of the circle)
Answer:
The answer is 2. hope it helps!
Step-by-step explanation:
Answer: The area of the shaded portion is [tex](\pi-2)~\textup{sq. units}.[/tex]
Correct option is 2.
Step-by-step explanation: We are given to find the area of the shaded portion in the figure.
Since, the centre point of each arc is the corresponding central point of the line and the arcs intersect at the centre point of the circle,
so let us divide the figure into four equal parts, one of them is square ABCD as shown in the attached figure.
The area of the square ABCD will be
[tex]A_{ABCD}=\left(\dfrac{1}{2}\times 2\right)^2\\\\\\\Rightarrow A_{ABCD}=1~\textup{sq. units}.[/tex]
Now, area of the shaded portion inside the square ABCD will be
[tex]A_s=2\times \textup{area of the quarter circle with radius 1 unit}}-\textup{area of square ABCD}\\\\\Rightarrow A_s=2\times \left(\pi\times \left(\dfrac{1}{2}\right)^2\right)-A_{ABCD}\\\\\\\Rightarrow A_s=2\times\left(\dfrac{\pi}{4}\right)-1\\\\\\\Rightarrow A_s=\left(\dfrac{\pi}{2}-1\right)~\textup{sq. units}.[/tex]
Since all the four squares are identical in the attached figure, so the required area of the total shaded portion in the figure is
[tex]A=2\times\left(\dfrac{\pi}{2}\right)\\\\\\\Rightarrow A=(\pi-2)~\textup{sq. units}.[/tex]
Thus, the area of the shaded portion is [tex](\pi-2)~\textup{sq. units}.[/tex]

Given: What type of angles are ∠2 and ∠3 are adjacent angles.
Which of the following options describes the adjacent angles in terms of their sum? complementary angles, 90° complementary angles, 180° supplementary angles, 90° supplementary angles, 180°
Final answer:
Adjacent angles can be either complementary or supplementary depending on their sum. Complementary angles add up to 90°, while supplementary angles sum to 180°. The term for adjacent angles in terms of their sum is 'supplementary angles', adding up to 180°.
Explanation:
Adjacent angles are two angles that have a common side and vertex, and don't overlap. In terms of their sum, if adjacent angles add up to 90 degrees, they are called complementary angles. If they add up to 180 degrees, they are called supplementary angles. Since the question involves angles ∠2 and ∠3 as adjacent angles but does not provide their specific measures, it's not possible to definitively classify them as complementary or supplementary without additional information. However, the question asks which term describes adjacent angles in terms of their sum. The correct answer is supplementary angles, which have a sum of 180°.

The true solution to [tex]3 log 2+log8 =2log(4x)[/tex] is [tex]x=2[/tex]. The correct option is b. [tex]x=2[/tex].
Given expression is[tex]3 \log 2+\log8 =2\log(4x)[/tex].
We have to calculate the value of [tex]x.[/tex]
Properties of logarithm:We know that,
[tex]n \log m= \log(m)^n[/tex]
and
[tex]\log m + \log n = \log(mn)[/tex]
Solving the equation:
[tex]3 \log 2+\log8 =2\log(4x)[/tex][tex]\log(2)^3+\log8 =\log(4x)^2[/tex]
{using [tex]n \log m= \log (m)^n[/tex]}
[tex]\log8+\log 8= \log 16x^2[/tex]
[tex]\log (8 \times8)=\log16x^2[/tex] {using [tex]log m + log n = log(mn)[/tex]}
Since log is on both sides so it is eliminated from both sides,
[tex]8 \times8=16x^2\\64=16x^2\\[/tex]
[tex]x^{2} =\frac{64}{16}\\x^{2}=4\\x=2[/tex]
Hence the true solution to [tex]3 log 2+log8 =2log(4x)[/tex] is [tex]x=2[/tex].

Answer:
30 + 0.15m
Step-by-step explanation:
base rate = 40(1 − 0.25) = 40(0.75) = 30
per mile = 0.15m
thus,
30 + 0.15m
The correct expression represents the situation is,
⇒ 30 + 0.15m
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Here, He has a coupon for 25% off the daily base rate of $40.
And, He will also have to pay an additional $0.15 for each mile he drives.
Let m represents the number of miles.
Hence, We can formulate;
⇒ 40 (1 - 0.25) + 0.15m
⇒ 40 × 0.75 + 0.15m
⇒ 30 + 0.15m
Thus, The correct expression represents the situation is,

The floor plan of a factory is dilated by a factor of 4 to create a new, larger floor plan.
The area of the new floor plan is _______ times larger than the area of the original floor plan?
a. 4
b. 8
c. 16
d. 64
e. 256
The original floor could be rectangle in shape.
If we consider the length of floor to be 'L' and width of floor to be 'W',
then area of original floor = length x width = LW.
And if its dimensions are dilated by scale factor of 4 to make new floor, then new length and width would become four times of older values. So new length would be '4L' and new width would be '4W'
Now area of new floor = length x width = 4L x 4W = 16LW.
It is clear that the area of new floor is 16 times of the area of original floor.
So, option C i.e. 16 is the final answer.
