Which of the following is a root of the polynomial shown below?
Mademuasel [1]

Answer:

We conclude that option A is true as x = 1 is the root of the polynomial.

Step-by-step explanation:

Given the polynomial

f\left(x\right)\:=\:x^2\:+\:2x^2\:-\:x-2

Let us determine the root of the polynomial shown below.

\:0=\:x^2\:+\:2x^2\:-\:x-2

0=3x^2-x-2

switch sides

3x^2-x-2=0

as

3x^2-x-2=\left(3x+2\right)\left(x-1\right)

so the equation becomes

\left(3x+2\right)\left(x-1\right)=0

Using the zero factor principle

3x+2=0\quad \mathrm{or}\quad \:x-1=0

solving

3x+2=0

3x=-2

\frac{3x}{3}=\frac{-2}{3}

x=-\frac{2}{3}

and

x-1=0

x=1

The possible roots of the polynomial will be:

x=-\frac{2}{3},\:x=1

Therefore, from the mentioned options, we conclude that option A is true as x = 1 is the root of the polynomial.

Emily leaves her house at exactly 8:25 a.m. to bike to her school, which is 3.42 miles away. When she passes the post office, wh
mafiozo [28]
First, let's find out the number of minutes Emily has to get to school. From 8:25 to 8:50, there are 25 minutes.

Next, let's find out  the number of minutes before Emily looks at her watch. From 8:25 to 8:28.50, there are 3.5 minutes.

Now let's calculate Emily's speed in miles per minute. To do so, divide the distance traveled by the time it took:

\frac{0.75}{3.5} miles/minute

Now let's calculate how far Emily can travel in 25 minutes going this speed. To do so, we multiply her speed by the time traveled:

\frac{0.75(25)}{3.5} =5.357 miles

5.357 miles is greater than 3.42 miles, so yes, Emily will make it to school on time.

Need Help. Will give brainiest for correct answer with reason/work.
Alexxandr [17]

Answer: y=1/x is the blue line and it goes straight up and down the y and x axis.

y=x^2 is the green line which is a thin "u" like shape. its going up the y axis.

y=\frac{x^{3}}{x^{2}-9} is the red line it goes up and down the y axis and diagonally across the middle of both axis'.

Step-by-step explanation: I went to desmos calculator and typed in your equation and it automatically gave me this graph. (See Picture for more details.)
