Answer:

The sequence is 1 , 2 , 3 , 4.

Step-by-step explanation:

From the questions we can observe that

1 = $1^{3}$

8 = $2^{3}$

27 = $3^{3}$

64 = $4^{3}$

∴ The sequence is 1 , 2 , 3 , 4.

Use the functions f(x)=7x3−3x2−x+14 f x = 7 x 3 - 3 x 2 - x + 14 and g(x)=2x3+2x+5 g x = 2 x 3 + 2 x + 5 as examples to show tha

Answer:

<h3>The given set of polynomials f(x) and g(x) are closed under subtraction.</h3>

Step-by-step explanation:

Given that the functions f ad g are defined by

$f(x)=7x^3-3x^2-x+14$ and $g(x)=2x^3+2x+5$ respectively.

<h3>To show that the set of polynomials is closed under subtraction :</h3>

Now subtract the given polynomials

$f(x)-g(x)=(f-g)(x)$

$=7x^3-3x^2-x+14-(2x^3+2x+5)$

$=7x^3-3x^2-x+14-2x^3-2x-5$

$=5x^3-3x^2-3x+9$

∴ $f(x)-g(x)=5x^3-3x^2-3x+9$

When subtracting the polynomials the variables and their exponents remains same only variation in their coefficients.

<h3>Hence the given polynomials f(x) and g(x) are closed under subtraction.</h3>

∴ $f(x)-g(x)=5x^3-3x^2-3x+9$ are closed under subtraction,

Hence showed.

Lines k and n are perpendicular. If the slope of line k is -6, what is the slope of line n?

CaHeK987 [17]

Lines k and n are perpendicular

The slope of line k is -6

Fact: The product of slopes of two perpendicular lines = -1

So the slope of line n = -1 ÷ -6 = 1/6

The correct choice is 'D.'
