Step-by-step explanation:

if multiply the 3 factors together you get

(x² - x - 2)(x - 3) - trinomial x binomial

x³ - 3x²- x² + 3x - 2x + 6 - polynomial

x³ - 4x² + x + 6, this is the polynomial with those factors.

Poly means many so it could be a bigger polynomial with more factors but if it is limited to only these factors than there is just the one polynomial.

The polynomial is x³ - 4x² + x + 6 with factors (x-2), (x+1), and (x-3)

A polynomial is the defined as mathematical expression that have a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

Given that ,

P(x) has three factors (x-2), (x+1), and (x-3).

Multiplying the 3 factors together, we get

⇒ (x-2)(x+1)(x-3)

⇒ [x(x-3) - 2(x+1)](x-3)

⇒ (x² - x - 2)(x - 3)

⇒ x³ - 3x²- x² + 3x - 2x + 6

Rearrange the terms likewise and apply arithmetic operations

⇒ x³ - 4x² + x + 6

Hence, the polynomial is x³ - 4x² + x + 6 with factors (x-2), (x+1), and (x-3).

Answer: A) 21.25 ≤ x ≤ 22.75

Step-by-step explanation:

Given, Average weight of basketballs = 22 ounces

It is possible for its weight to vary at most 0.75 ounces from this average.

Let x denotes the weight of the basket ball.

Then, the required range  for a basketball's weight:

Average-0.75 ≤ x ≤ Average+0.75

⇒22-0.75 ≤ x ≤ 22+0.75

⇒21.25 ≤ x ≤ 22.75

Hence, the range for a basketball's weight: 21.25 ≤ x ≤ 22.75 .

Correct option: A) 21.25 ≤ x ≤ 22.75

4,500 Codes

Step-by-step explanation:

Given that, the access code consists of 4 digits.

Since, the First digit cannot be zero, and the last digit has to be even.

Therefore, Locks can only use numbers (0-9), which means the first digit has 9 possible outcomes ( 1-9),

the 2nd has 10 possible outcomes (0-10),

the same with the 3rd (0-10) and

finally the 4th has only 5 possible outcomes (0,2,4,6,8),

which we assume that zero is not excluded.

Finally, Mulitply 9 x 10 x 10 x 5 = 4,500.

Answer:

nine added to seven times a number.

Step-by-step explanation:

''x'' is the unknown number which is being multiplied by 7. Than 9 is added to it.

y = 2x+1 and y = 2x-2 have the same slope, but different y intercepts. This means the lines are parallel. So the boundary lines are parallel.

y > 2x+1 indicates we'll shade above the y = 2x+1 boundary line

y < 2x-2 tells us to shade below the y = 2x-2 boundary line

Both boundary lines are solid lines (and not dashed line) because of the "or equal to" portion

What results is similar to what you see in choice A. However, the red boundary line should go through (0,1) and not (0,2). The blue boundary line should go through (0,-2) and not (0,-1)

Basically take the graph of choice A and shift everything down 1 unit and you'll have your final answer.

This graph shows the solution to the system of linear inequalities

y ≥ 2x + 1

y ≤ 2x - 2

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Answer:

43 cups

Step-by-step explanation:

Subtract the height of the one cup from the stack

73 - 10

63

The rest of the cup each add 1.5 cm to the stack

take the remaining height and divide by 1.5 for each cup

63  cm/ 1.5 cm per cup

42 cup

There are 42 cups in the remaining part of the stack

Plus the 1 cup that is 10 cm

42+1 = 43 cups total in the stack

Answer:

[tex]\boxed{\sf 43 \ cups}[/tex]

The stack is 73 cm tall, one cup is 10 cm.

Let’s subtract the height of the one cup from the height of the stack.

[tex]\sf 73 - 10\\=63[/tex]

The cups left each add 1.5 cm.

Let x be the cups left.

[tex]\sf 1.5x=63\\x=\frac{63}{1.5} \\x=42[/tex]

Add the 1 to the cups left, because that first cup was subtracted from the height of the stack.

Answer:

Step-by-step explanation:

A term, loosely defined, is a product of numbers and variables. Terms are separated from one another with a + or a - sign. So we have 2 terms here.

The degree of the polynomial, because it is just in terms of x and no other variable, is the highest degree'd term.  Our highest degree of x is 3, so this is a third degree polynomial.

It is classified by its number of terms:

1 term is a monomial, 2 terms is a binomial, 3 is a trinomial, and anything higher is just called a "polynomial". This has 2 terms so it is a binomial.

The answer is:

Work/explanation:

Here's how we classify polynomials based on the number of terms:

monomial - has only one term

binomial - has two terms

trinomial - has three terms

polynomial - has four terms or more

As for degrees, those are the highest exponents the polynomial.

Now, [tex]\sf{14x^3+x^2}[/tex] has 2 terms so it's a binomial; the highest exponent is 3.

Answer:

The correct option is;

B. The robot filters the expected amount of air and water, but it doesn't use the expected amount of energy

Step-by-step explanation:

The given requirements are;

Volume of air and water to be filtered by the robot = 343 liters

The amount of energy consumed by the robot < 49 joules

The number of minutes the robot filters air and water to filter more than 343 liters = 12A + 8W > 343

The number of minutes the robot filters air and with less than 49 Joule of energy = 3A + 4W < 49

Given that filtering air takes 20 minutes, filtering water takes 15 minutes, we have;

To filter more than 343 liters, we have

12*20 + 8*15 = 360 > 343

The robot meets the amount of air and water requirement

To filter with less than 49 joules we have

3*20 + 4*15 = 120 > 49

Therefore, the robot does not meet the energy requirement

The correct option is the robot filters the expected amount of air and water, but it doesn't use the expected amount of energy.

Factoring out the i was never needed.

Answer:

She shouldn't have factored out the i.

Step-by-step explanation:

In both parentheses, only one of the two additives had an "i" in it, so only one of them could have i factored out of it. If she wanted to factor out the i, the equation would look like this:

Answer:

the answer is XY = 24 units.

Step-by-step explanation:

Given:

XY is tangent to the circles with center P and O respectively.

OX=16 units

PY=6 units

OP=26 units

To find:

Side XY = ?

Solution:

As per given statement, the diagram of two circles and their tangent is shown in the diagram.

We need to do one construction here,

Draw a line parallel to tangent XY from P towards OX such that it meets OX at A .

Now, let us consider triangle [tex]\triangle OAP[/tex]. It is a right angled triangle.

With sides Hypotenuse, OP = 26 units  

Perpendicular, OA = 16 -6  = 10 units

Base AP is equal to XY.

If we find the value of Base AP, the value of XY is calculated automatically.

Let us use pythagorean theorem in [tex]\triangle OAP[/tex]:

According to pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OP^{2} = AP^{2} + OA^{2} \\\Rightarrow 26^2=XY^2+10^2\\\Rightarrow XY^2 = 676- 100\\\Rightarrow XY = \sqrt{576}\\\Rightarrow XY = 24\ units[/tex]

Hence, the answer is XY = 24 units.

Answer:

Options (2), (3) and (4) are correct.

Step-by-step explanation:

The given function is f(x) = [tex]-\sqrt[3]{x}[/tex]

1). First derivative of the function = f'(x) = [tex]\frac{d}{dx}(-\sqrt[3]{x} )[/tex]

  f'(x) = [tex]-\frac{1}{3}(x)^{-\frac{2}{3}}[/tex]

  Since derivative is negative, function will be decreasing everywhere.

  Therefore, Option (1) is incorrect.

2). Since value of the function is true for every value of all real values of x.

  Domain of the function is (-∞, ∞).

  Therefore, Option (2) is correct.

3). For the given domain, range of the function will be all real values of y Or (-∞, ∞)

  Therefore, Option (3) is correct.

4). Function 'f' when reflected across x axis, equation of the reflected function will be g(x) = [tex]\sqrt[3]{x}[/tex].

 Therefore, Option (4) is correct.

5). For a point (3, -27),

  -27 = [tex]-\sqrt[3]{3}[/tex]

  Therefore, Option (5) is incorrect.

let price of sugar was 100

So total expense = 100*10=1000

But now new expense =1100 (I,e.10% more than 1000)

and new price =120(i,e. 20% more than 100)

So new consumption = new expense/ new price=

Answer:

1. [tex]\bold{S=f(P) = 0.07P}[/tex]

2. x = 16

3. Part 1: P is the independent variable and S is the dependent variable.

Part 2: x is the independent variable and y is the dependent variable.

Step-by-step explanation:

1. To write the function notation for:

Sales tax is 7% of the total price.

Let the total price be [tex]P[/tex].

And sales tax be [tex]S[/tex].

As per the given statement:

[tex]S = 7\% \ of\ P\\\Rightarrow S =\dfrac{7}{100}P\\\Rightarrow S=0.07P[/tex]

Writing it in the function notation:

[tex]\bold{S=f(P) = 0.07P}[/tex]

2. To find the value of x such that [tex]f(x) = 14[/tex] and

[tex]f(x) = \dfrac{1}4x + 10[/tex]

Putting the value of [tex]f(x) = 14[/tex]

[tex]14 = \dfrac{1}4x + 10\\\Rightarrow \dfrac{1}4x =14-10\\\Rightarrow \dfrac{1}4x =4\\\Rightarrow x =4\times 4\\\Rightarrow \bold{x =16}[/tex]

3. To find the dependent and independent variable.

Independent variables are those whose value is not dependent on the other variable's values.

Dependent variables are dependent on the value of other variables.

In question 1:

[tex]\bold{S=f(P) = 0.07P}[/tex]

P is the independent variable.

S is the dependent variable.

In question 2:

If we write it as follows:

[tex]y=f(x) = \dfrac{1}4x + 10[/tex]

x is the independent variable and y is the dependent variable.
