Use The Equation Of The Polynomial Function F(x)=2x3x To Complete The Following.(a) State The Degree

Answers

Answer 1

The function given is,

[tex]f(x)=-2x^3-x[/tex](a)

We need to find the degree and leading coefficient of the function.

The degree is the highest power of the polynomial.

We can see that it is a cubic polynomial, or, a third degree function.

The leading coefficient is the coefficient of the highest degree term.

In our case, -2 is the leading coefficient because it is the coefficient of x^3.

(b)

The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity.

Let's graph the function:

From the graph, we can see,

• As x approaches infinity, the function approaches negative infinity

,

• As x approaches negative infinity, the function approaches positive infinity

This describes the end behavior of the function.

(c)

From our function graphed above, we see that "D", from the answer choices, represents the correct graph of this function.

Answer(s)(a)

The degree of the polynomial is 3 and the leading coefficient is - 2.

(b)

The curve opens down to the right because the leading coefficient is negative. Because the polynomial is cubic, the graph has end behaviors in the opposite direction, so the other end opens up to the left.

(c)

Answers

Answer:

6 points

Explanations:

Let the number of points scored by Michael be m

Rajesh is filing single and he has an adjusted gross income (AGI) of $84,000 for the 2018 tax year. He qualifies for the standard deduction of $12,000. Use the following 2018 Federal tax rate schedule to calculate his 2018 Federal income tax.

If your filing status is single;

Answers

Rajesh's tax in 2028 is $11,779.50 based on his adjusted gross income (AGI), standard deduction, and filling status.

How to find the tax?

First, find the taxable income:

= adjusted gross income (AGI) - standard deduction

= 84,000 - 12,000

= $72,000

This taxable income is in the $38,700 - $82,500 bracket so Rajesh's tax in 2018 would be:

= 4,453.50 + 22% of the excess over $38,700:

Solving for the tax to be paid by Rajesh in 2018 is:

= 4,453.50 + ( 22% x (72,000 - 38,700))

= $11,779.50

In conclusion, the tax that Rajesh would pay in 2018 is $11,779.50.

1 month bet Rented 3 movies and 2 videos games for a total of $21 the next month she rented 8 movies and four game for a total of $49 find the rental cost for each movie and each video game

Answers

Let "m" represent the cost of one movie rent and "v" represent the cost of one videogame rent.

One month she rented 3 movies and 2 videogames for a total of $21, you can express the total cost for this month as:

[tex]3m+2v=21[/tex]

Another month she rented 8 movies and 4 video games for a total of $49, you can express the rental costs for this month as follows:

[tex]8m+4v=49[/tex]

These expressions form an equation system. To solve it, the first step is to write one of the equations in terms of one of the variables, for example, write the first equation for "v"

[tex]\begin{gathered} 3m+2v=21 \\ 3m-3m+2v=21-3m \\ 2v=21-3m \\ \frac{2v}{2}=\frac{21}{2}-\frac{3}{2}m \\ v=\frac{21}{2}-\frac{3}{2}m \end{gathered}[/tex]

Next, replace the expression obtained for "v" into the second equation and solve for "m"

[tex]\begin{gathered} 8m+4v=49 \\ 8m+4(\frac{21}{2}-\frac{3}{2}m)=49 \end{gathered}[/tex]

-Distribute the multiplication on the parentheses term:

[tex]\begin{gathered} 8m+4\cdot\frac{21}{2}-4\cdot\frac{3}{2}m=49 \\ 8m+42-6m=49 \end{gathered}[/tex]

-Order the like terms together and simplify them:

[tex]\begin{gathered} 8m-6m+42=49 \\ 2m+42=49 \end{gathered}[/tex]

-Pass 42 to the right side of the equation by applying the opposite operation to both sides of the equal sign:

[tex]\begin{gathered} 2m+42-42=49-42 \\ 2m=7 \end{gathered}[/tex]

-Divide both sides by 2 to determine the value of m:

[tex]\begin{gathered} \frac{2m}{2}=\frac{7}{2} \\ m=\frac{7}{2}\approx3.5 \end{gathered}[/tex]

-Replace the value obtained for "m" on the expression for "v" to determine the rental cost of one video game:

[tex]\begin{gathered} v=\frac{21}{2}-\frac{3}{2}m \\ v=\frac{21}{2}-\frac{3}{2}\cdot\frac{7}{2} \\ v=\frac{21}{2}-\frac{21}{4} \\ v=\frac{21}{4}\approx5.25 \end{gathered}[/tex]

The rental cost for the movies is m=$3.50/movie and the rental cost for the videogames is v=$5.25/video game

a radio disc jockey has 8 songs. on the upcoming playlist:2 rock songs3 reggae songs3 country songsthe disc jockey Randomly choose the 1st song to play, then Randomly choose the 2nd song from the remaining ones. what is the Probability that the 1st song is a Rock song? the 2nd song is a Country song?* write as fraction

Answers

Probabilities

We have the following elements to choose from:

Rock songs (R) = 2

Reggaes songs (G) = 3

Country songs (C) = 3

It's required to find two probabilities:

a) The first is a rock song

As stated above, there are R = 2 rocks songs and there are 8 songs in total, thus the probability of randomly picking a rock song is:

[tex]\begin{gathered} p(R)=\frac{2}{8} \\ \text{Simplify:} \\ p(R)=\frac{1}{4} \end{gathered}[/tex]

b) The second song is a country song.

This is quite more complex to calculate. Let's assume the first song was not a Country song (NC). This has a probability of:

[tex]P(NC)=\frac{5}{8}[/tex]

Since there are 5 non-country songs out of 8. For the second pick, we have all of the country songs unplayed out of 7, thus the probability of selecting it is:

[tex]P(C)=\frac{3}{7}[/tex]

The probability of this 'brank' of events is:

[tex]P(NC,C)=\frac{5}{8}\cdot\frac{3}{7}=\frac{15}{56}[/tex]

Now assume the first song was actually a country song. It has a probability of:

[tex]P(C)=\frac{3}{8}[/tex]

For the second pick, we now have only 2 country songs out of 7, so the probability of selecting another country song is:

[tex]P(C)=\frac{2}{7}[/tex]

The probability of this 'branch' of events is:

[tex]\begin{gathered} P(C,C)=\frac{3}{8}\cdot\frac{2}{7}=\frac{6}{56} \\ Simplify\colon \\ P(C,C)=\frac{3}{28} \end{gathered}[/tex]

The total probability of selecting a country song as the second song is:

[tex]\begin{gathered} P(B)=\frac{15}{56}+\frac{3}{28} \\ P(B)=\frac{15}{56}+\frac{6}{56} \\ P(B)=\frac{21}{56} \\ P(B)=\frac{3}{8} \end{gathered}[/tex]

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

We have to determine the slope of the line :

⇒ m = (y₂ - y₁)/(x₂ -x₁ )

⇒ m = (560 - 359)/(10-0)

⇒ m = 20.1

This represents new assistants per year

Given that a store purchased an item for $90.

They want a profit of 40% of their costs.

What is a fraction?

A number that represents a rational number is called a common fraction. A decimal, percent, or negative exponent can all be used to represent the same number. For instance, the fraction 1/100 is equivalent to the values 0.01, 1%, and 102. The implicit denominator of an integer can be conceived of as being one (for instance, 7 = 7/1). The term "set of rational numbers" in mathematics refers to the collection of all numbers that can be stated in the form a/b, where a and b are integers and b is not zero. This collection is denoted by the letter Q, which stands for quotient. When a number can be expressed in that way, it is said to be a rational number (i.e., as a common fraction).

1/7 + 2/5

= (5 + 14)/35
