Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. there is nothing to do

Answers

Answer:

Step-by-step explanation: There are no solutions whenever k=4,5mod9.

This holds since it is not difficult to verify that for every integer n, we have n3=0,±1mod9.

Up till this year, there were just two values for k in the range 1..100 for which it was not known if there were a solution. These values are k=33,42.

Both values are now known to have solutions. See 42 is the answer to the question “

How is pH and hydronium concentration related?


Please help I am so confused

Answers

The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH.

If the hydronium concentration increases, the pH decreases, causing the solution to

become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution

Write an equation of the line in slope-intercept form (0,-2) ,(2,2)

Answers

Answer:

y=2x-2

Step-by-step explanation:

Slope intercept Formula: y=mx+b

y= Y coordinate

m = slope

x = x coordinate

b = y intercept

Point Slope Formula: y-y1=m(x-x1)

Slope Formula: m= y2-y1 / x2-x1

2 - (-2) / 2-0 = 4 / 2 = 2

y- (-2) = 2 (x - 0) = y+2=2x-0

y=2x-2

Answers

Answer:

y=9x+60

Step-by-step explanation:

An equation in slope-intercept form to find the height (in feet) of the tree, y, after x years is y=9x+60.

Given that, the tree grows at an approximate rate of 9 inches per year.

What is the slope intercept form?

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

We know that, 1 feet =12 inches

So, 5 feet =60 inches

Let the height of the tree be y and the number of years be x.

Now, equations is y=9x+60

Therefore, an equation in slope-intercept form to find the height (in feet) of the tree, y, after x years is y=9x+60.

Answer:

A

Step-by-step explanation:

3n+17=26 Inverse operation of addition is subtraction so subtract 17 from both sides of the equation

3n-17+17=26-17

3n=19 Inverse operation of multiplication is division, so divide 3 from both sides of the equation so you can get n alone

3n/3=9/3

n=3

Laura paid 9.35 for 3.4 pounds of ground beef. How much does one pound of ground beef cost?

Answers

Answer:

One pound of ground beef costs $2.75.

Step-by-step explanation:

To solve this you want to divide both numbers by 3.4 this is because you want to find out much the ground beef costs per 1 pound and 3.4 / 3.4 = 1. Additionally, what you do to one side you must do to the other!

3.4 / 3.4 = 1

9.35 / 3.4 = 2.75

One pound of ground beef costs $2.75.

simplify 2(x + 5) − 3(x − 2)

Answers

Answer:

-x + 16

Step-by-step explanation:

We need to use the distributive property to solve this!

We can isolate this into 2 parts that we will need to combine later on, but isolating them will make it less confusing to simplify:

2(x+5) is one part, and the second is -3(x-2)

The first part simplifies to 2x + 10, and the second simplifies to -3x + 6. Now we need to combine the 2 values.

2x + 10 - 3x + 6

Combine like terms

-x + 16 is your answer!

Answer:

Step-by-step explanation:

2x+10 - 3x -5 and for the fun of it the answer will be..

you will subtract 10 and 5 and that gives you 5

then you do -3+2 = -1x

5 divided by -1 gives you

Graph the parabola.
y=3(x-2)²+1
Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function
button.

Answers

Answer
Vertex:(2,1)
Focus:(2, 13/12)
Axis of symmetry: x=2
Directrix: y=11/12

A parabola is a curve with a focus and a directrix. The focus is any point is at an equal distance while the directrix  is a fixed line. The vertex of the parabola is (2,1), the two points to the right are (3,4) & (4,13) while the two points to the left are (1,4) & (0,13).

Given that:

[tex]y = 3(x - 2)^2 + 1[/tex]

A parabola is represented as:

[tex]y = a(x - h)^2 + k[/tex]

Where:

[tex]Vertex = (h,k)[/tex]

So, by comparison; the vertex of the function is:

[tex]Vertex = (2,1)[/tex]

To plot two points to the right, we select x values greater than 2.

Let: [tex]x = 3[/tex]

So, we have:

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(3 - 2)^2 + 1[/tex]

[tex]y = 4[/tex]

Let [tex]x = 4[/tex]

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(4 - 2)^2 + 1[/tex]

[tex]y =13[/tex]

To plot two points to the left, we select x values less than 2.

Let: [tex]x=1[/tex]

So, we have:

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(1 - 2)^2 + 1[/tex]

[tex]y = 4[/tex]

Let [tex]x = 0[/tex]

[tex]y = 3(x - 2)^2 + 1[/tex]

[tex]y = 3(0 - 2)^2 + 1[/tex]

[tex]y =13[/tex]

In conclusion:

The vertex of the parabola is (2,1)The two points on the right are (3,4) and (4,13)The two points on the left are (1,4) and (0,13)
