Answer:

r = ± [tex]\sqrt{q^2-p^4[/tex]

Step-by-step explanation:

p² = [tex]\sqrt{q^2-r^2}[/tex] ( square both sides )

(p² )² = q² - r²

[tex]p^{4}[/tex] = q² - r² ( subtract q² from both sides )

[tex]p^{4}[/tex] - q² = - r² ( multiply through by - 1 )

q² - [tex]p^{4}[/tex] = r² ( take square root of both sides )

± [tex]\sqrt{q^2-p^4}[/tex] = r

Answer:

[tex]\frac{b}{4}+2=-1[/tex]

Subtract 2 from both sides:

[tex]\frac{b}{4}+2-2=-1-2[/tex]

[tex]\frac{b}{4}=-3[/tex]

Multiply 4 to both sides:

[tex]4*\frac{b}{4} =-3*4[/tex]

[tex]b=-12[/tex]

Answer:

(-2.5,3) is x1 y1 respectivelly. Apart from this, what part of the question are you struggling with?

Option D is correct, the value of the rational expression when x = –3 is undefined.

An expression is combination of variables, numbers and operators.

The given expression is x/x²-9

x divided by x square minus nine.

Now let us find the value of the expression when x is minus three,

Plug in x as -3 in the above expression.

-3/(-3)²-9

-3/9-9

-3/0

Anything divided by zero then the value is undefined.

Hence, Option D is correct, the value of the rational expression when x = –3 is undefined.

A

Step-by-step explanation:

Given a polynomial in standard form

The leading coefficient is the coefficient of the variable with the largest exponent.

The term with the largest exponent of the variable is

[tex]\frac{1}{4}[/tex] [tex]x^{5}[/tex]

Then the leading coefficient is [tex]\frac{1}{4}[/tex] → A

Answer:

125.1698 Ft

Step-by-step explanation:

Answer: 0.1125

Step-by-step explanation:

To divide decimals, you move the decimal (.) to the end.

In this case of 0.009 /0.08,

you move the period in 0.08 to the end so it become 8.

And since you moved it two spaces to the right, you do the same for the 0.009 (you move the period 2 spaces to the right), so it becomes 0.9

Then you divide.

Hopefully, that makes sense.

c

Step-by-step explanation:

c represents adding 5 and n together, and multiplying it by four.

Four times the sum of five and a number equivalent expression is 4(5 + n) which is the correct answer would be an option (C).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs arithmetic operations is called arithmetic operator.

Operators let do basic mathematical calculations.

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

For example 4 + 2 = 6

Let the number be n

To determine the four times the sum of five and a number

The sum of five and a number as

⇒ 5 + n

So, four times the sum of five and a number as

⇒ 4*(5 + n)

Hence, four times the sum of five and a number equivalent expression is  4(5 + n).

Answer:

the negative 5 is showing that you are losing grain in the silo because you are letting some out.

Answer:

58 divided by 4 = 14. 5 mph

72.5 Divided by 4 = 14.5 mph

87 divided by 6 = 14.5 mph

k = 14.5 mph

Y= Kx = 14.5X

answer is 14.5 and 14.5X

Step-by-step explanation:

The student went from x+y = 2 to 2x+2y = 2, which is not correct. They multiplied the left side by 2, but forgot about the right hand side.

They should have gone from x+y = 2 to 2x+2y = 4 after multiplying both sides by 2.

So they should have this new equivalent system

[tex]\begin{cases}3x-2y = 8\\2x+2y = 4\end{cases}[/tex]

Add straight down and we end up with the new equation 5x = 12 which solves to x = 12/5 = 2.4

Use that x value to solve for y. You should get y = -2/5 = -0.4

variable

Step-by-step explanation:

1st Rate of change is 18 - 0 / 0.5 - 0 = 18/0.5 = 36

2nd rate of change is 32 - 18 / 1.5 -0.5 = 14 / 1 = 14

3rd rate of change is 26 - 32 / 2 - 1.5 = -6/0.5 = -12

so the rates of change are variable

Answer:

x + 9y²

Step-by-step explanation:

A prime polynomial is simply an irreducible polynomial.

x + 9y² is a prime polynomial

First, we test the options.

x + 9y²

The above function cannot be reduced further.

Hence, x + 9y² is a prime polynomial

3m + 9n

Factor out 3

3 (m + 3n)

3m + 9n is not a prime because it can be factored as 3 (m + 3n)

8x^7 - 9x + 12x²

Factor out x

x(8x^6 - 9 + 12x)

8x^7 - 9x + 12x² is not a prime because it can be factored as x(8x^6 - 9 + 12x)

Hence, x + 9y² is a prime polynomial
