Use this scenario: A truck rental agency offers two kinds of plans. Plan A charges
Luba_88 [7]

we conclude that for 500 miles, both plans will have the same cost.

<h3>For how many miles both plans have the same cost?</h3>

Plan A charges a fixed amount of $75, plus $0.10 per mile, so if you drive x miles, the cost equation is:

A(x) = $75 + $0.10*x

For plan B we will have the similar equation:

B(x) = $100 + $0.05*x

The cost is the same in both plans when:

A(x) = B(x)

So we need to solve the linear equation:

$75 + $0.10*x =  $100 + $0.05*x

$0.10*x - $0.05*x = $100 - $75

$0.05*x = $25

x = $25/$0.05 = 500

So we conclude that for 500 miles, both plans will have the same cost.

there are 3 seniors for every 2 juniors in the concert choir. if there are 21 seniors in all, how many jurors are in the concert
Oxana [17]

The ratio ...

... seniors : juniors = 3 : 2

can be multiplied by 7 to get

... = 21 : 14

indicating there are 14 juniors for the 21 seniors in the choir.

Answer:

SUMMARY:

x^4+\frac{5}{x^3}-\sqrt{x}+8                               →    Not a Polynomial

-x^5+7x-\frac{1}{2}x^2+9                           →    A Polynomial

x^4+x^3\sqrt{7}+2x^2-\frac{\sqrt{3}}{2}x+\pi              →    A Polynomial

\left|x\right|^2+4\sqrt{x}-2                                   →    Not a Polynomial

x^3-4x-3                                        →    A Polynomial

\frac{4}{x^2-4x+3}                                              →    Not a Polynomial

Step-by-step explanation:

The algebraic expressions are said to be the polynomials in one variable which consist of terms in the form ax^n.

Here:

n = non-negative integer

a = is a real number (also the the coefficient of the term).

Lets check whether the Algebraic Expression are polynomials or not.

Given the expression

x^4+\frac{5}{x^3}-\sqrt{x}+8

If an algebraic expression contains a radical in it then it isn’t a polynomial. In the given algebraic expression contains \sqrt{x}, so it is not a polynomial.

Also it contains the term \frac{5}{x^3} which can be written as 5x^{-3}, meaning this algebraic expression really has a negative exponent in it which is not allowed. Therefore, the expression x^4+\frac{5}{x^3}-\sqrt{x}+8 is not a polynomial.

Given the expression

-x^5+7x-\frac{1}{2}x^2+9

This algebraic expression is a polynomial. The degree of a polynomial in one variable is considered to be the largest power in the polynomial. Therefore, the algebraic expression is a polynomial is a polynomial with degree 5.

Given the expression

x^4+x^3\sqrt{7}+2x^2-\frac{\sqrt{3}}{2}x+\pi

in a polynomial with a degree 4. Notice, the coefficient of the term can be in radical. No issue!

Given the expression

\left|x\right|^2+4\sqrt{x}-2

is not a polynomial because algebraic expression contains a radical in it.

Given the expression

x^3-4x-3

a polynomial with a degree 3. As it does not violate any condition as mentioned above.

Given the expression

\frac{4}{x^2-4x+3}

\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}

Therefore, is not a polynomial because algebraic expression really has a negative exponent in it which is not allowed.

SUMMARY:

x^4+\frac{5}{x^3}-\sqrt{x}+8                               →    Not a Polynomial

-x^5+7x-\frac{1}{2}x^2+9                           →    A Polynomial

\frac{4}{x^2-4x+3}                                              →    Not a Polynomial
