Hello Person!!

Here's the correct answer choice! ^^

There are three steps.

The steps are at 8 from 0 to 1, at 12 from 1 to 2, and at 16 from 2 to 3.

Closed circles are on the left side of each step, and open circles are on the right.

Step-by-step explanation:

Because,

Given that y=4 is the equation

This is on the interval [0,3]

Since y=4 for all x, we get

when x=0, y=4. when x =1, y=4 and so on.

In other words, if we connect (0,4),(1,4)...(3,4) we get a horizontal line parallel to x axis passing through the above points from x=0 to x=3

ii) x=2 on [0,3]

Here x is constant but  y varies from 0 to 3

When y takes values from 0 to 3, x =2 always

Hence a vertical line placed parallel to y axis a a disance of 2 units from  y axis.

P.S Tell me if this is wrong....

Answer:

Step-by-step explanation:

steps are in picture.

Note: if you have any question about it you can ask.

Answer:

y= (x^2-3) + 2

Step-by-step explanation:

It is plus two on the end to go up 2 on the y axis since the question says up two units and in the parenthesis is where you can move the start of and line, exponential line, or parabola to the left or to the right. When in the parenthesis, if you do however many x's and whatever exponent there is if you plus it will go into the negatives, ot left, and minus will go positive, or right. Therefore the answer is y= (x^2-3) +2.

BTW, when writing exponents,  this: ^, is an exponent sign but working on certain platforms will allow you to write them like in the image, and if it can then you should write it like that.

Hope this helps!

What is inequality ?

In mathematics, an inequality represents the connection between two values in an imbalanced algebraic statement. A sign of inequality can be used to show that one of the two variables is larger than, greater than or equal to, less than, or equal to another value.

According to question

a represents the number of tables sold and y represents the number of chairs sold

Using a and y as variables, we get

a + y ≤ 18

100y + 400a ≥ 2900

Simplified,

100(y + 4a) ≥ 2900

y + 4a ≤ 29

Given the minimum number of tables that need to be sold, we evaluate using a = 10

y + 4(10) ≥ 29

y ≥ -11

y represents the number of chairs sold

therefore, y ≥ 0

Since we can't purchase -11  chair, we round up our result giving us y ≥ 0

Now

the store must sell a minimum of 10 tables and tables for $400 each

then

10*400 = $4000

which is more than worth of chairs and tables $2900

hence Zero possible solution.

The vector normal to the plane passing through the points (-7,2,-1), (-2,1,-5), and (-2,2,-3) is <4,17,11>.

To find the vector normal to the plane passing through three given points, we need to first find two vectors lying on the plane. We can do this by taking the difference between the first two points and the last two points.

Vector 1: (-7,2,-1) - (-2,1,-5) = <-5,1,4>

Vector 2: (-2,2,-3) - (-2,1,-5) = <0,1,2>

Next, we take the cross product of these two vectors to get the normal vector:

<4,17,11> = <-5,1,4> x <0,1,2>

The resulting vector is perpendicular to both vector 1 and vector 2, and hence lies on the plane passing through the three given points.

Step-by-step explanation:

The probability of selecting a boy for president is 7/12, the ratio of the number of boys to the number of candidates. Then the probability of selecting a girl for vice president is 5/11, the ratio of the number of girls to the remaining number of candidates. The joint probability is ...

We can also look at this another way.

The number of ways two candidates can be selected from 12 is 12P2 = 132. The number of ways that the first can be a boy and the second can be a girl is (7)(5) = 35. Then the probability of a (BG) pair from the 12 candidates is 35/132.

Therefore, when the number of copies made in a month is above 4000, company A's charges are higher than company B's charges in the given equation.

Let's start by setting up an equation to represent the cost of renting a copier from each company:

Cost for company A = 0.10x + 200

Cost for company B = 0.05x + 400

where x is the number of copies made in a month.

To find the number of copies above which company A's charges are higher than company B's charges, we need to set the two equations equal to each other and solve for x:

0.10x + 200 = 0.05x + 400

0.05x = 200

x = 4000

I tried my best and I think this is right?

When a person walks 5.0 kilometers north, they are moving in a straight line towards the north direction.

If they then walk 5.0 kilometers east, they are moving in a straight line towards the east direction. To find the person's displacement, we need to calculate the straight-line distance between their starting point and their ending point.

We can use the Pythagorean theorem to do this. If we draw a right-angled triangle with the northward distance as the vertical leg and the eastward distance as the horizontal leg,

The hypotenuse of the triangle will be the straight-line distance between the starting and ending points.

Using the Pythagorean theorem, we can calculate the hypotenuse as follows: hypotenuse^2 = (northward distance)^2 + (eastward distance)^2, hypotenuse^2 = (5.0 km)^2 + (5.0 km)^2, hypotenuse^2 = 50 km^2, hypotenuse = sqrt(50) km.

hypotenuse = 7.07 km (rounded to two decimal places), Therefore, the person's displacement is closest to 7.07 kilometers. This means that the straight-line distance between their starting and ending points is 7.07 kilometers, even though they walked a total distance of 10 kilometers.

The displacement can be found by using the Pythagorean theorem, as it represents the shortest distance between the initial and final points of the person's journey. In this case, we have a right triangle with legs of 5.0 kilometers north and 5.0 kilometers east.

Applying the Pythagorean theorem, we get:

Displacement^2 = (5.0 km)^2 + (5.0 km)^2
Displacement^2 = 25 km^2 + 25 km^2
Displacement^2 = 50 km^2

To find the displacement, take the square root:
Displacement ≈ √50 km ≈ 7.07 km
So, the person's displacement is closest to 7.07 kilometers in the northeast direction.

The value of x when y = 84 is 14

From the question,

The value of y varies directly with x

That is,

y ∝ x

Introducing the constant of proportionality, k

We get,

y = kx

Also, from the question

If x = 3, then y = 18

Putting these values into the equation, we can determine the value of k

\(y = kx\)

\(18 = k \times 3\)

Now, divide both sides by 3

\(\frac{18}{3}=\frac{k \times 3}{3}\)

\(6 = k\)

∴ k = 6

Now, to determine the value of x when y = 84

We will put y = 84 and the value of k =6 into the equation

\(y = kx\)

\(84 = 6 x\)

Divide both sides by 6

\(\frac{84}{6} = \frac{6x}{6}\)

\(14 = x\)

∴ \(x = 14\)

Hence, the value of x when y = 84 is 14

The largest area that can be enclosed if 88 feet of fencing material is available is 484 feet².

Given, a barn has a perimeter of 88 feet.

Now, the perimeter of the rectangle i.e. Barn is 88 feet.

Perimeter = 2(l + b)

88 = 2(l + b)

l + b = 44

b = 44 - l

Now, area = l × b

Area = l × (44 - l)

Area = 44l - l²

On differentiating both the sides, we get

A' = 44 - 2l

On putting A' = 0

44 - 2l = 0

l = 22

Now, for l = 22 the area will be the largest.

if l = 22

then, 22 + b = 44

b = 22

So, the largest area will be 22×22 = 484

Hence, the largest area that can be enclosed if 88 feet of fencing material is available is 484 feet².

The addition of the polynomial \(x^{3}+3xy-2xy^{2} +y^{3}\) with \(2x^{3}-5x^{2} y-3xy^{2}-2y^{3}\) is  \(3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}\).

What is a polynomial?

⇒ A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

⇒ In the addition of polynomials, the like terms are added while in subtraction, the like terms are subtracted.

Calculation;

We have been given two polynomial which we have to add   \(x^{3}+3xy-2xy^{2} +y^{3}\) and \(2x^{3}-5x^{2} y-3xy^{2}-2y^{3}\)

The sign after addition or subtraction will always be of the variable having more value.

\((x^{3}+3xy-2xy^{2} +y^{3} )+(2x^{3}-5x^{2} y-3xy^{2}-2y^{3})\)

On adding like terms with each other

⇒ \((x^{3} +2x^{3})+ 3xy-5x^{2} y-(2xy^{2}+3xy^{2})+(y^{3}-2x^{3})\)

⇒ \(3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}\)

Hence the addition of the polynomial\(x^{3}+3xy-2xy^{2} +y^{3}\) and \(2x^{3}-5x^{2} y-3xy^{2}-2y^{3}\) is \(3x^{3}+3xy-5x^{2} y-5xy^{2}-y^{3}\).
