What is factor of the polynomial?
A polynomial with coefficients in a certain field or in integers is expressed as the product of irreducible factors with coefficients in the same domain in mathematics and computer algebra, which is known as polynomial factorization.
A polynomial can be factored by expressing it as the product of two or more components; this is somewhat the opposite of multiplying.
From the given graph we can see that, graph crosses x - axis at points
x = 1 and x = 8.
That means x = 1, 8 are the zero of the polynomial.
Since, if x = a is a zero of the polynomial, then (x - a) is the factor of the polynomial.
As x = 1, 8 are zero of the polynomial so (x - 1) and (x - 8) are the factors of the polynomial.
Hence, from the given options (x - 1) is factor of the polynomial.

So first you need to get x on its own, so you you need to get rid of -16 by adding +16 which you get 0.
so now x=-88
whatever you do on one side you do on the other, so add 16 to the other side (-88) so you get -72.

What is the Poisson Distribution Formula?The Normal, Binomial, and Poisson Distributions are the three types of continuous and discrete data-based distributions used in probability and statistics. The distribution of unusual occurrences is another name for the Poisson distribution. This is mostly used to forecast the likelihood of future events based on how frequently the past events occurred. It offers the chance that a specific number of events might happen during a particular time frame.
The formula for Poisson distribution is given below:
P(x) = (e^-x * m^x) / x!
Here we have,
flaws in a carpet tend to occur randomly and independently at a rate of one every 270 square feet
Given the dimensions of carpet = 7 feet × 12 feet
=> area of the carpet = 84 feet²
=> the expected mean of defects m = [1/270]*84 = 0.311
Now use the Poisson formula
P[x] = e^-m × m^x / x!

you want to order posters to advertise your band. a company charges $109.95 for the first 100 posters and $65 for each additional 100 posters. a. write the equation where $y$ represents the total cost (in dollars) as a function of $x$ , the number (in hundreds) of posters ordered.
Answers
The required question based on number of posters is y = 109.95 + 65x.
The cost of additional posters = 65x, based on the mentioned information.The 100 posters make 1 set. Assuming the total number of posters be x. So, the additional sets will be calculated by the formula = (x - 100)/100.
Now, the equation will be the sum of the cost of first 100 posters and the cost of remaining posters.
y = 109.95 + 65x
Thus, the equation with the total cost (in dollars) as a function of the number (in hundreds) of posters ordered is y = 109.95 + 65x.

x + 40° + 58° = 180°
x + 98° = 180°
subtract 98°
x = 82°
Answer:
x = 82°
Step-by-step explanation:
The sum of the internal angles of a triangle = 180°

What is the equation of line that passes through the given point and parallel to the given equation?The equation of line is expressed as;
y = mx + b
The point-slope formula is expressed as;
y - y₁ = m( x - x₁ )
Where m is slope and b is the y-intercept.
Given the data in the question;
Equation: x - y = 3Point: (2,-4)
x = 2y = -4First, reorder the given equation in slope-intercept form and determine the slope.
x - y = 3
x = 3 + y
3 + y = x
y = x - 3
Hence,
The slope m = 1
To find the line parallel to the equation, the slope must be equal.
Find the line using point-slope formula.
y - y₁ = m( x - x₁ )
Plug in slope m = 1 and point: (2,-4)
y - ( -4 ) = (1)( x - 2 )

What is an equation of the line that passes through the points (4, −2) and (2, 3)?
Answers
The equation of the line, in slope-intercept form, that passes through
(4, 2) and (-2, -3) is y = 5/6 x - 4/3.
What is slope-intercept form?
The meaning of slope-intercept form is the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
Using two points and slope-intercept form we can find the equation of the line.
According to the given question:
The formula to find the slope of two points (x₁, y₁) and (x₂, y₂) is
m = (y₂ - y₁) / (x₂ - x₁)
The points given are (4, 2) and (-2, -3)
m = (-3 - 2) / (-2 - 4)
m = -5/ -6
m = 5/6
Now using the slope and the point (4, 2) the y intercept is
y = mx + b
2 = 5/6 (4) + b
2 = 10/3 + b
By further calculation,
b = 2 - 10/3
Taking LCM
b = (6 - 10)/3 = -4/3
By writing the equation in slope intercept form
y = mx + b
y = 5/6x - 4/3
Therefore, the equation of the line in slope intercept form is
y = 5/6 x - 4/3.

How to get the degree of a polynomial?
For any given polynomial, we define the degree as the largest exponent on the polynomial.
On this case we have:
f(x) = 2x^3 - 3x^5 - x^2 + 1
We can see that the largest exponent is 5, so the degree is 5.
Now, for the ending behavior.
If we have an odd degree (like in this case) we will have opposite ending behaviors in both ends of the domain.

if 1,000 points are selected randomly inside the square with all points equally likely to be selected, how many of those points are expected to lie inside the circle?
Answers
The number of points that are expected to lie inside the circle is 785.
A circle is a closed two-dimensional figure. In a circle, all points are equidistant from the centre.
As per the given question, the circle is inscribed in a square,
The radius of the circle ( r ) = 1 The side length of the square ( s ) = 2⇒ The area of the circle = π × r × r
= π × 1 × 1
∴ The area of the circle = π
⇒ The area of the square = s × s
= 2 × 2
∴The area of the square = 4
The probability that a randomly selected point inside the square will lie inside the circle,
p = π / 4
The probability that a randomly selected point inside the square will lie outside the circle,
q = 1 - p
q = 1 - ( π / 4 )
⇒ Binomial trial with n = 1000 and p = π / 4,
Number of points expected to lie inside the circle(N) = n × p
= 1000 × ( π / 4 )
= 1000 × ( 3.14 / 4 )
= 1000 × ( 0.785 )
N = 785
Therefore, 785 expected points lie inside the circle.

For a debt of 10%:

Step-by-step explanation:
Hello,
So first step is we would use the bi-weekly net pay of $1465.87 then times it by 26 so it would look like this
1465.87 × 26 = 38112.62
Then we would divide 38112.62 by 12
38112.62 ÷ 12 = 3176.0516
Then, we would determine how much the social worker can spend if the monthly budget for debt is between 5% and 10%.
3176.0516 × 5% = 158.80
3176.0516 × 10% = 317.61
So, therefore the answer is $158.80 ≤ m ≤ $317.61.

Answer:
All the answer are A
Step-by-step explanation:
Area = length times width
405 = x15 Divide both sides by 15
27 = x
For the x intercept Let y = o and solve for x
5x - 3y -15 = 0
5x - 3(0) -15 = 0
5x -15 = 0 Add 15 to both sides of the equation
5x = 15 Divide both sides by 5
x = 3
The x intercept is (3,0)
For the y intercept Let x = 0 and sole for y
5x -3y -15 = 0
-3y -15 = 0 Add 15 to both sides of the equation
-3y = 15 Divide both sides by -3
y = -5
The y intercept is (0,-5)
4x + 3y + 7x - y Combine the like terms
