The given function is even.

Solution:

Given function:

[tex]f(x)=x^{6}-x^{4}[/tex]

If f(-x) = -f(x), then the function is odd.

If f(-x) = f(x), then the function is even.

[tex]f(x)=x^{6}-x^{4}[/tex]

Substitute x = -x

[tex]f(-x)=(-x)^{6}-(-x)^{4}[/tex]

          [tex]=x^{6}-x^{4}[/tex]

          = f(x)   (given)

   f(-x) = f(x)

From the definition, it is even.

Hence the given function is even.

Answer:

(6, 9 ) and r = 3

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

x² + y² - 12x - 18y + 108 = 0

Rearrange the x- terms and the y- terms together and subtract 108 from both sides, that is

x² - 12x + y² - 18y = - 108

To obtain standard form use the method of completing the square

add ( half the coefficient of the x and y terms )² to both sides

x² + 2(- 6)x + 36 + y² + 2(- 9)y + 81 = - 108 + 36 + 81

(x - 6)² + (y - 9)² = 9 ← in standard form

with centre = (6, 9 ) and r = [tex]\sqrt{9}[/tex] = 3

The circumference of the soccer ball can be found using the formula for the circumference of a circle, to which 10 inches is then added to find the total length of the ribbon Regina needs.

The problem involves understanding the mathematical concept of circumference. The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. In this case, the soccer ball has a radius of 4.5 inches. Therefore, the circumference of the soccer ball would be C = 2π(4.5) inches.

Then, the problem states that the ribbon needs to be 10 inches longer than the circumference of the ball. So the total length of the ribbon that Regina needs is C + 10 inches. By substituting the values, we get the length of the ribbon needed.

Answer:

y = -5

Step-by-step explanation:

x= (-22+2y)/4 = -3+y

-22+2y = 4(-3+y)

-22+2y = -12+4y

-22+12 = 4y-2y

-10 = 2y

-10/2 = y

-5 = y

Answer:

x = -8

y = -5

Step-by-step explanation:

From the given expression, let's make two equations

4x   -   2y =   - 22--------------------------(i)

-x    +   y  =     3-----------------------------(ii)

to easily substitute, lets make another equation from equation (ii)

y  =  3  +   x

substitute (y=3+x) in equation (i)

4x   -   2 (x+3)   =   -22

4x  -   2x   -  6   =   -22

2x  -  6   =   -22

2x       =   -22   +  6

2x    =  -  16

x   = -16  /  2

x  =   -  8

lets solve for (y) by substituting   (x =  - 8) in equation   (ii)

-  (- 8)  +  y = 3

8  +  y  =   3

8  +  y  = 3

y  =  3  -  8

y  =  -  5

Therefore:

x  =  -  8

y  =  -  5

Answer:

For x=20: difference is 22

Step-by-step explanation:

For f: y increased 5 units (from 1 to 6) when x went from 0 to 10. Being linear, when x=20, f will increase with another 5 units, being 6+5=11.

For g: g(20)=1.5×20+3=33

So, for x=20, f(20)-g(20)=11-33=-22

So the difference is 22.

x= 2,3

Step-by-step explanation:

a. $0.811

b. $0.75

c.  10-ounce package of cashews costs $8.11 is better then a 16-ounce package of cashews costs $12

Step-by-step explanation:

Here we have , 10-ounce package of cashews costs $8.11, and a 16-ounce package of cashews costs $12.  

a. What is the cost per ounce for the 10-ounce package of cashews?

​cost per ounce for the 10-ounce package of cashews = [tex]\frac{8.11}{10}[/tex]

​cost per ounce for the 10-ounce package of cashews = $[tex]0.811[/tex]

b. ​What is the cost per ounce for the 16-ounce package of cashews?

cost per ounce for the 16-ounce package of cashews = [tex]\frac{12}{16}[/tex]

cost per ounce for the 16-ounce package of cashews = $[tex]0.75[/tex]

c. Which package is the better buy?

10-ounce package of cashews costs $8.11 is better then a 16-ounce package of cashews costs $12 , because cost per ounce for the 10-ounce package of cashews = $[tex]0.811[/tex] is greater then cost per ounce for the 16-ounce package of cashews = $[tex]0.75[/tex]

The cost per ounce for the 10-ounce package of cashews is $0.811, and the cost per ounce for the 16-ounce package is $0.75. The 16-ounce package is the better buy.

a. To find the cost per ounce for the 10-ounce package of cashews, we divide the total cost by the number of ounces. $8.11 ÷ 10 ounces = $0.811 per ounce.

b. To find the cost per ounce for the 16-ounce package of cashews, we divide the total cost by the number of ounces. $12 ÷ 16 ounces = $0.75 per ounce.

c. The better buy is the package with the lower cost per ounce. Therefore, the 16-ounce package of cashews is the better buy.

This results in a final answer of 94.

The question asks for the calculation of 2 times the difference of 73 and twice the sum of 9 and 4. Let's break it down step by step:

Therefore, 2 times the difference of 73 and twice the sum of 9 and 4 equals 94.

Answer:

15% discount means you're paying 85% of the marked price because total is 100% and 100-15 = 85%

Let X be the naked price

Paid = marked price - discount

Paid = X - (15/100 × X)

Using distribution property,

Paid = X(1 - 15/100)

Paid = X[(100-15)/100]

Paid = X(85/100)

Which is 85/100 × X

Hence 85% of X

Answer: 85% = 0.85

While 15% = 0.15

Step-by-step explanation:

Percentage is a fraction whose denominator is 100. So if we say 15%, we mean 15/100 = 0.15.

If want to find 15% of a 100, it means 15% of 100 = 15/100 × 100 = 15.

To find 85 % of 100 means 85/100 × 100= 85

hence subtraction of 15% from 100% is 85%

Therefore 15% = 15/100 = 0.15

While 85% is 85/100 = 0.85

Answer:

Yes, this is true.

Step-by-step explanation:

If you substitue x for -1 you get -3(-1+8)=-21, Then you add -1 and 8 so you should get 7. After, you multiply 7 times -3 you get -21. Proving this statement is correct.

Answer:

See below.

Step-by-step explanation:

We can solve for x:

−3(x+8) = −21

Distribute the -3 over the parentheses:

-3x - 24 = -21

Add 24 to both sides:

-3x -24 + 24 = -21 + 24

-3x = 3

Divide both sides by -3:

x = -1.

So that proves the original equation.

Answer:

A) 12k + 10

B) $160

Step-by-step explanation:

6(2k + 5) - 20

12k + 30 - 20

12k + 10

k = 12.5

12(12.5) + 10 = 160

Answer:

12k +10

Final cos = 160

Step-by-step explanation:

6(2k + 5) - 20

Distribute the 6

6*2k + 6*5 -20

12k +30 -20

12k +10

Let k =12.5

12*12.5 +10

The coordinates for the shape are;

a = (0, 0), b = (a, 0), c = (a, a), and d = (0, a).

Step-by-step explanation:

Step 1:

First, we must assign letters to the four vertices of the given shape.

Assume the lower-left vertex is a, the lower-right vertex is b, the upper-right vertex is c and the upper-left vertex is d.

So the vertices for the shape are a, b, c, and d.

Step 2:

The coordinates for a point on a graph is given by (x coordinate, y coordinate).

So we need to determine the x and y coordinates for the four points on the shape abcd.

Step 3;

The x coordinate for vertex a = 0, the y coordinate for vertex a = 0,

so the coordinates of vertex a = (0, 0).

The x coordinate for vertex b = a - 0 = a, the y coordinate for vertex b = 0,

so the coordinates of vertex b = (a, 0).

The x coordinate for vertex c = a- 0 =a, the y coordinate for vertex c = a- 0= a, so the coordinates of vertex c = (a, a).

The x coordinate for vertex d = 0, the y coordinate for vertex d = a - 0 =a,

so the coordinates of vertex d = (0, a).

Step-by-step explanation:

15% as a decimal is 0.15

40*0.15 is 6

6 guests arrive early

6 people arrive early to the party.

Calculating the Number of People Who Arrive Early to a Party

To calculate the number of people who arrive early to a party where 40 people are expected, we use the given percentage of guests that arrive early, which in this case is 15%. The calculation process is straightforward:

Convert the percentage to a decimal by dividing by 100, which gives us 0.15.

Multiply the decimal by the total number of people expected at the party to find the number of people who arrive early.

So, the calculation is:

0.15 x 40 = 6

Therefore, 6 people arrive early to the party.

Answer: 3/4

Step-by-step explanation:

To take this ratio to its simplest form, we have to divide by a value divisible by the numerator and denominator.

12 ÷ 3 = 4

Thus, 9/12 = 3/4

By applying formula of area of rectangle we got that if susie is painting a wall that is 12 feet tall and 9 feet wide if each can of paint has enough paint to cover 8 square feet then total 12 cans of paint will susie need to cover the whole wall​

Rectangle is a regular quadrilateral with all angle equal to right angle.

Given that wall that is 12 feet tall and 9 feet wide

So area of rectangle = length[tex]\times[/tex]width

Area= [tex]12\times 8=96[/tex]

Given that each can of paint has enough paint to cover 8 square feet
