A student went on a two-day hike. • On day one, the student hiked 11 kilometers. On day two, the student hiked at a rate of 2 kilometers per hour for x hours. Which of the following graphs represents y, the total distance, in kilometers, the student hiked over both days after hiking for x hours on day two?​

Answers

Answer 1

The slope is 2, which equals the distance travelled each hour. The total distance hiked at the start of the second day is represented by the y-intercept, which is 4, which is also the y-value. intercept's

Explain about the Slope?

We locate the rise/run before calculating the slope. Since the line increases by 2 between each point, the rise is 2. It travels over 1 between the points, hence the run is 1. The slope is now 2/1, or 2.

Given that it is rise/run, this gives us miles/hours, which indicates the number of miles she treks per hour.

The line's crossing of the y-axis is known as the y-intercept. At four, this is.

The fact that the y-value at this time is 4 and the x-value at this point is 0 tells us that she has trekked 4 miles in the 0 hours since the start of the second day, which is the distance she has covered so far.

mr. and mrs. zeta want to name their baby zeta so that its monogram (first, middle, and last initials) will be in alphabetical order with no letters repeated. how many such monograms are possible?

Answers

Mr. and Mrs. Zeta want to make sure that their baby's monogram, which consists of the first, middle, and last initials, is in alphabetical order with no letters repeated. We may utilize the idea of permutations to determine the number of possible monograms.

A permutation is a way to arrange a group of things in a particular sequence. In this instance, we are examining the alphabet's set of letters (from A to Z), and we are trying to determine how many different ways there are to arrange them so that the monogram is composed entirely of unique letters.

The breakdown of the computation is as follows:

There are 26 different alternatives for the first initial (A to Z).

Since the monogram must be in alphabetical sequence, the letter for the second initial must appear after the first initial. There are so 25 possibilities left (the letters that come after the first initial in the alphabet).

There are 24 possibilities left for the final initial (the remaining letters that come after the second initial in the alphabet).

By multiplying the alternatives for each initial, we can calculate the total number of possible monograms using the basic counting principle:

26 x 25 x 24 = 15,600

Because they must be in alphabetical order and contain no repeating letters, there are 15,600 number of monograms are possible .

an element in a ring is called an idempotent if . prove that the only idempotents in an integral domain are and . find a ring with a idempotent not equal to 0 or 1.

Answers

A ring with a idempotent not equal to 0 or 1 is 3 and 4.

Make (R,+) a domain that is integral.

As a commutative ring with two elements, R, ab = 0 when either an or b are equal to zero.

If a ∈ R is an idempotent element, then a ≠ 0,a ≠ 1 will result.

[tex]a^{2}[/tex] = a

We can take multiple of 1 because the same number return if we multiply 1 to any number.

[tex]a^{2}[/tex] = a·1

Subtract a·1 on both side, we get

[tex]a^{2}[/tex] - a·1 = 0

Taking a common

a(a -1) = 0

(a -1) = 0 or a =0

R has no zero divisors.

So, a = 1 or a = 0

As a result, the only idempotent elements in the integral domain R are 0 and 1.

A ring that is not equal to 0 or 1 and is idempotent.

A ring with respect to addition and multiplication is the set R = 0 through 5.

Let 3 ∈ R,

[tex]3^{2}[/tex] = 6+3 = 0+3 = 3

Let 4 ∈ R.

[tex]4^{2}[/tex] = 16 = 12+4 = 2

For example, if the polynomial is given as [tex]ax^{2}[/tex] + bx + c, then the zeros can be determined by solving the equation [tex]ax^{2}[/tex] + bx + c=0.

Step 1: To determine the zeros of the polynomial, set the polynomial equal to 0 and solve for x.

f(x) = [tex]x^{3}[/tex] - [tex]3x^{2}[/tex] + 4 = 0

Step 2: Factor the polynomial to solve for x.

[tex]x^{3}[/tex] - [tex]3x^{2}[/tex] + 4 = 0

x([tex]x^{2}[/tex] - 3x + 4) = 0

Step 3: Factor the quadratic equation.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences. The modern definition of function was first given in 1837 by the German mathematician Peter Dirichlet.

This relationship is commonly symbolized as y = f(x)—which is said “f of x”—and y and x are related such that for every x, there is a unique value of y. That is, f(x) can not have more than one value for the same x. To use the language of set theory, a function relates an element x to an element f(x) in another set.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The first linear equation is - x + 3y = 5

The second linear equation is - -3x - 2y = 20

On evaluating individually the equation obtained is -

-3x - 2y + x + 3y = 20 + 5

-2x + y = 25

Multiply equation (1) with 3 -

3(x + 3y) = 5 × 3

3x + 9y = 15.....(3)

Adding equation (3) and (2) -

-3x - 2y + (3x + 9y) = 20 + 15

-3x - 2y + 3x + 9y = 35

-2y + 9y = 35

7y = 35

y = 35/7

y = 5

Substituting the value of y in equation (1) -

x + 3y = 5

x + 3(5) = 5

x + 15 = 5

x = 5 - 15

x = -10

B) Horizontal Asymptote

C) Vertical Asymptote

D) Domain

Answers

Answer:

B) Horizontal Asymptote

A horizontal asymptote is a horizontal line that the graph of a function approaches as the input values get larger or smaller. The end behavior of a rational function is determined by the degree of the numerator and denominator. If the degree of the numerator is less than the degree of the denominator, the function will approach a horizontal asymptote as the x-values get larger or smaller. If the degree of the numerator is greater than the degree of the denominator, the function will not have a horizontal asymptote.

What is volume ?

Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

As we know Volume of sphere V=

[tex]V=\frac{4}{3} \pi r^3\\dv/dt=6\\Given\\radius=3cm\\[/tex]

so, we need to find dr/dt

Since there is no t in our equation. So differentiate using chain rule

[tex]\frac{dv}{dt} =\frac{dv}{dr} *\frac{dr}{dt} \\[/tex]

Since, in question it is given dv/dt=6

[tex]6=\frac{dv}{dr} .\frac{dr}{dt} \\[/tex]

To find dv/dr differentiate

 [tex]4/3\pi r^3\\dv/dr(\frac{4}{3} \pi r^3)=4\pi r^2\\6=4\pi r^2\frac{dr}{dt} \\[/tex]

Dividing

[tex]\frac{10}{4\pi (3)^2} =dr/dt\\dr/dt=\frac{10}{36\pi } \\[/tex]

The radius is increasing at rate of 10/36π

What is volume ?

Volume' is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

As we know Volume of sphere V= 4/3 πr³

dv/dt =6

Given  r = 3 cm.

so, we need to find dr/dt

Since there is not in our equation. So differentiate using chain rule

dv/dt =dv/dr * dr/dt

Since, in question it is given dv/dt=6

6 =dv/dr * dr/dt

To find dv/dr differentiate

dv/dr (4/3πr³) = 4πr²

6 = 4πr² dr/dt

Finally,

dv/dt = 10/36π

Hence, The radius is increasing at rate of 10/36π

The row percentage of A is 0% , B is 83.3% and of C is 15.4%.

Percentage describes the relative value of a number. Its shows the 100th part of the number with respect to a number whose value is provided in the problem.

Here various data is given about A, B and C in the format of two tables and this shows the relationship between the two.

Now, the row  percentage of A is

[tex]\frac{0}{5} * 100=0%[/tex]%

Then, the row percentage of B is

[tex]\frac{10}{12}*100 = 83.3%[/tex]%
