The ordered pairs (1, 1), (2, 8), (3, 27), (4, 64), and (5, 125) represent a function. What is a rule that represents this funct
Zarrin [17]
The functions would be:

D. y=x³

We can check it out.

(1,1); x=1; y=1 ⇒1=(1)³=1*1*1=1
(2,8); x=2; y=8 ⇒8=(2)³=2*2*2=8
(3,27); x=3; y=27 ⇒27=3³=3*3*3=27
(4,64): x=4; y=64 ⇒64=4³=4*4*4=64
(5,125); x=5; y=125 ⇔ 125=5³=5*5*5=125

Rewrite the following expression using the properties of rational exponents. Be sure your answer is in simplest form.
Nookie1986 [14]

Answer:

(2\cdot 6)^{\frac{3}{2}}=24(3)^{\frac{1}{2}}

Step-by-step explanation:

The given expression is (2*6)^{\frac{3}{2}}

We multiply within the parenthesis to get:

(12)^{\frac{3}{2}}

Recall that: a^{\frac{m}{n} } =\sqrt[n]{x^m}

We apply this property to get:

(12)^{\frac{3}{2}}=\sqrt{12^3}

(12)^{\frac{3}{2}}=\sqrt{12^2*12}

This simplifies to

(12)^{\frac{3}{2}}=12\sqrt{12}

We can simplify further

(12)^{\frac{3}{2}}=12\sqrt{4*3}=12*2\sqrt{3}=24\sqrt{3}

We rewrite as rational exponent  24(3)^{\frac{1}{2}}

What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3).
Rina8888 [55]

Sum of standard form polynomials means adding the terms of same variable. The sum of the given polynomial in standard form is,

-x^2+2x-3

<h3>What is polynomial equation?</h3>

A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.

Here, <em>n</em> is any real number.

In the polynomial equation the the terms are added or subtracted from each other only when the power of the variable is same.

Given information-

The first polynomial equations given in the problem is,

(x^2 - 3x)

The second polynomial equations given in the problem is,

(-2x^2+ 5x - 3).

To find the sum of these two polynomials, add the two terms together as,

(x^2 - 3x)+(-2x^2+ 5x - 3)

Let the result of the sum is f(x). Thus,

f(x)=(x^2 - 3x)+(-2x^2+ 5x - 3)\\f(x)=x^2-3x-2x^2+5x-3

Separate the similar power variable as,

f(x)=(x^2-2x^2)+(-3x+5x)-3\\f(x)=-x^2+2x-3

Thus the sum of the given polynomial in standard form is,

-x^2+2x-3
