What are the linear factors of the function f(x) = 2x^3 − 3x^2 − 2x + 3? Select each correct answer.
(x − 2)
(2x − 3)
(x − 1)
(2x + 3)
(x + 1)
(x + 2)
Edit: I ended up getting the answer the old fashioned way, working it out. The answers are (2x - 3), (x - 1), and (x + 1).
Answer:
The factors of the polynomial are (x+1), (2x-3) and (x -1)
Step-by-step explanation:
Here, we want to know the linear factors of the function.
What we simply want to calculate are those factors when multiplied with each other gives the polynomial in question.
We start by looking at the polynomial itself, we discover that the polynomial in question is a polynomial of degree three. What this means is that the polynomial will have three roots.
In this kind of question, we make use of testing.
Testing in the sense that since we know that the factor of a polynomial if substituted in that polynomial will give no remainder( 0)
So let’s say we start with one of the options (x-1)
We set this to 0
x -1 = 0
This implies that x = 1
So make a substitution of x= 1 in the polynomial
We will get;
2(1)^3 - 3(1)^2 -2(1) + 3 = 2-3-2+3 = 0
This means that (x-1) is actually a factor
The next thing to do is to use the polynomial long division; That will be;
(2x^3 − 3x^2 − 2x + 3)/ (x-1)
This gives ;
2x^2 -x -3
We can now proceed to factorize the quadratic equation;
That will be;
2x^2 + 2x -3x -3
= 2x(x + 1) -3( x + 1)
So the factors are;
(2x-3)(x+ 1)
These are the two other factors aside (x-1)

Show your work and steps. If your answer is not an integer, explain what two integers your answer is between. 2. What is the mean change in the forecasted low temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.
Answer:
The table is missing in the question. The table is provided below.
Step-by-step explanation:
1. In the table, it is given the difference of high temperature. They are :
-7, -7, 2, 5, -3, -2
Now adding the differences of high temperatures and taking out its average.
-7 + (-7) + 2 + 5 + (-3) + (-2)= -12
Average : [tex]$-\frac{12}{6}=-2$[/tex]
Thus the answer is an integer.
2. In the table, it is given the difference of high temperature. They are :
0, -3, -7, -1, 1, 0
Now adding the differences of high temperatures and taking out its average.
0 + (-3) + (-7 )+ (-1) + 1 + 0= -10
Average : [tex]$-\frac{10}{6} = -1.66$[/tex]
Thus, the answer is not an integer. The answer lies between the integers -2 to -1.

Find two functions defined implicitly by the given relation y^2-64x^2=64
Answer: The two functions are
f(x) = sqrt(64x^2+64)
g(x) = -sqrt(64x^2+64)
Graphing these together forms a hyperbola
To get these two functions, we need to solve for y
y^2 - 64x^2 = 64
y^2 = 64x^2 + 64
y = sqrt(64x^2 + 64) or y = -sqrt(64x^2 + 64)
The last line is similar to how x^2 = 9 has two solutions (x = plus or minus 3)

Answer:
[tex]v(t)=\dfrac{3\pi}{5}\cos{(3\pi t)}[/tex]
Step-by-step explanation:
The velocity is the derivative of position.
[tex]s(t)=3+ \dfrac{1}{5} \sin{(3\pi t)}\\\\v(t)=s'(t)=\dfrac{1}{5}(3\pi)\cos{(3\pi t)}\\\\\boxed{v(t)=\dfrac{3\pi}{5}\cos{(3\pi t)}}[/tex]
. Mount Everest is 29,028 feet above sea level. The bottom of the Mariana Trench is 36,070 feet below sea level. What is the difference between these two elevations?
The difference between these two elevations is 7024 feet.
Given,
Mount Everest is 29,028 feet above sea level.
The bottom of the Mariana Trench is 36,070 feet below sea level.
We need to find out what is the difference between these two elevations.
How do we measure the distance above and below sea level?When we measure the distance above sea level we measure it as a positive distance but when we measure the distance below the surface we measure it as a negative distance.
Find the distance of Mount Everest above sea level.
= 29.028
Find the distance of the Mariana trench below sea level.
= 36,070
Find the difference in distance between them.
We are to find the difference in distance between them not the distance between them.
So,
Mariana trench is higher than Mount Everest by:
= 36,070 - 29,028
= 7024 feet
Thus the difference between these two elevations is 7024 feet.

what is front-end estimation
Front-end estimation is a particular way of rounding numbers to estimate sums and differences.
To use front- end estimation, add or subtract only the numbers in the greatest place value. Then add the decimals rounded to the nearest tenth.
Step-by-step explanation:
In front end estimation we are going to replace the original number with a number that is close by but only has one non zero digit. Examples: {20, 300, -50, 1,000, 80,000}. For example take the number 32, the choices to replace it with are 30 or 40 (they both have only one non-zero digit).

Write an equation of the line that passes through the given points (-2, -6) and (1, 2).
Answer: 3y - 8x + 2 = 0
Step-by-step explanation:
The formula is
y - y₁ y₂ - y₁
------- = ---------- where x₁ = -2, x₂ = 1, y₁ = -6, y₂ = 2,
x - x₁ x₂ - x₁
Now we substitute for the values in the above equation and then solve.
y - (-6) 2 - (-6) 2 + 6 8
---------- = ----------- = --------- = ----
x - (-2) 1 - (-2) 1 + 2 3
y + 6 8
-------- = ---- , we now cross multiply to get the required equation.
x + 2 3
3( y + 6 ) = 8( x + 2 )
3y + 18 = 8x + 16
3y - 8x + 18 - 16 = 0
3y - 8x + 2 = 0

Explain the steps you would take to graph 2x-3y>15
Answer:
Step-by-step explanation:
In order to graph this properly, you will have to rewrite the inequality first
To do this you will have to get y by itself
First subtract 2x from both sides of the inequality
This will give you -3y>15-2x
Then you will divide -3 from both sides. When dividing by a negative, both sides of the inequality will flip
-3y/-3 < 15/-3 + -2x/-3
This should end up looking like this once it's divided
y < -5+ 2x/3
Rewrite in slope intercept form
y < 2/3x -5
Your slope= 2/3
Your y-intercept=(0,-5)
In order to graph this you will have to mark your y-intercept at (0,-5) From there you will plot the points going up and down using your slope 2/3.
Remember 2/3= rise over run, meaning you will go up 2 and across right 3 to receive your second point going up. When you are graphing down it will be two down and across left 3.
