Answer:

A polynomial is an algebraic expression made up of two or more terms subtracted, added, or multiplied. A polynomial can contain coefficients, variables, exponents, constants, and operators such as addition and subtraction.

It is also important to note that, a polynomial can’t have fractional or negative exponents. Examples of polynomials are; 3y2 + 2x + 5, x3 + 2 x 2 − 9 x – 4, 10 x 3 + 5 x + y, 4x2 – 5x + 7) etc. Like number, polynomials can undergo addition, subtraction, multiplication, and division.

We saw addition, subtraction, multiplication, and long division of polynomials previously.

Answer:

731,100

7.311 × 10^5

Step-by-step explanation:

The computation of the number of sheet used by other department is given below:

Given  that

The company used 7.4 × 10^5 sheets of paper So it would be 740,000  

And, The accounting department used 8.9 × 10^3 sheets so it would be 8,900  

Now the number of sheet used by other department is

= 740,000 - 8,900

= 731,100

= 7.311 × 10^5

Answer:

8 dimes

7 quarters

Step-by-step explanation:

Let number of

Dimes = x ; quarters = y

10x + 25y = 255 ___(1)

25x + 10y = 270 ___(2)

From (1)

10x = 255 - 25y

x = (255 - 25y) / 10

x = 25.5 - 2.5y

Put x = 25.5 - 2.5y in (2)

25(25.5 - 2.5y) + 10y = 270

637.5 - 62.5y + 10y = 270

-52.5y = - 367.5

y = 367.5 / 52.5

y = 7

x = 25.5 - 2.5(7)

x = 25.5 - 17.5

x = 8

Answer:

  x = 10

Step-by-step explanation:

Half of the triangle makes a 30°-60°-90° "special" triangle. We know the side ratios of that are 1 : √3 : 2. The long side is 1/3 of the perimeter, so is 60/3 = 20 = 10×2. Then the altitude is 10 times the middle ratio value: 10√3 ≈ 17.32.

Comparing this with x√3, we find x = 10.

Answer:

X = 25

Step-by-step explanation:

To solve this question, we'll first of all find determine the side length of the triangle from the perimeter.

Perimeter of an equilaterial triangle = 3 * s

S = side length

Perimeter = 150cm

150 = 3s

S = 150 / 3

S = 50cm

The side lengths are 50cm each since they are all equal.

To find x,

We have to divide the triangle equally into two different part.

Check the first attachment for better illustration on how the equilaterial triangle is.

Check the second attachment for better illustration on the triangle when its divided into a right angle triangle.

From the right angle triangle, we can use pythagorean theorem to solve for x

a² = b² + c²

a = 50cm

b = 25cm

c = x√(3)

50² = [x√(3)]² + 25²

2500 = x² * 3 + 625

2500 - 625 = 3x²

1875 = 3x²

X² = 1875 / 3

X² = 625

X = √(625)

X = 25

Answer:

explanation

6.022*10^23 molecules=40g.

7.00*10^23=40*7.00*10^23/6.022*10^23 g =46.5 g

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.65g  are  7.00 x 10²²  molecules of NaOH.

The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of NaOH= 7.00 x 10²² atoms

Substituting the values

mole=7.00 x 10²²÷ 6.022×10²³

mole =0.116 moles of NaOH

mass of NaOH= Molar mass of NaOH× moles of NaOH

= 40 × 0.116

= 4.65g

Therefore, 4.65g are  7.00 x 10²²  molecules of NaOH.

It looks like a "V" going straight up from 0, and hits both 4 and -4 y while going up perfectly

The graph opens upward, and it has a vertex of (0,0)

The vertex of an equation is the minimum or the maximum point on the graph of the equation

The equation of the graph is given as:

[tex]f(x) = 4|x|[/tex]

The above equation represents an absolute value function

An absolute value function is represented as:

[tex]f(x) = a|x -h| + k[/tex]

So, by comparison, we have:

[tex]a = 4[/tex]

[tex]h = 0[/tex]

[tex]k = 0[/tex]

This means that the graph opens upward, and it has a vertex of (0,0)

See attachment for the graph of [tex]f(x) = 4|x|[/tex]

Answer:

Middle answer is right

Step-by-step explanation:

The first answer is obliviously wrong so therefore it is the last two options

-(x+1)^2

= -(x^2+2x+1)

= -x^2-2x-1-3             (add the -3)

= x^2-2x-4

y intercept make x=0 therefore y=-4

AOS is x= -b/2a

x=2/2 which is 1
