Which of the following polynomial functions is graphed below?
A. f(x)=(x+5)(x+1)^2(x-1)
B. f(x)=(x-5)(x-1)^2(x-1)
C. f(x)=(x+2)^2(x-3)(x+1)
D. f(x)=(x-2)^2(x+3)(x-1)
Considering the graph shown, the polynomial represented is
A. f(x) = (x + 5) (x + 1)² (x - 1)How to determine the equation graphedThe x-intercept(s) of the function's graph, or the actual zero of a function, is the location on a graph where the function's graph crosses the x-axis.
Tracing the graph, the zeros or the x intercepts on the graph it can be traced to be:
x = -5x = -1x = 1solving the zeros
x = -5, x + 5 = 0
x = -1, x + 1 = 0
x = 1, x - 1 = 0

In linear equation, 44 is the total admission cost.
What in mathematics is a linear equation?
An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Linear equations with two variables, and so forth, are what the equation is known as if it has two variables.

We can write the given expression (3x² - 10x + 7/ x + 4) in synthetic form as :
- 4 |3 -10 7
What is Synthetic Division?In algebra, the synthetic division is one of the methods used to manually perform the Euclidean division of polynomials. The division of polynomials can also be done using the long division method. But, in comparison to the long division method of polynomials, the synthetic division requires lesser writing and fewer calculations. That means the synthetic division is the shorter method of the traditional long-division of a polynomial for the special cases when dividing by a linear factor.Given is the expression as -
(3x² - 10x + 7/ x + 4)
We can write the given expression in synthetic form as -
- 4 |3 -10 7
Therefore, we can write the given expression (3x² - 10x + 7/ x + 4) in synthetic form as :
- 4 |3 -10 7

in a savings account earning 4.25%
simple interest per year.
How much interest will Bianca earn for a period of 3
years?
Bianca will earn interest of $382.5 for a period of 3years.
What is simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same.
Simple interest is calculated with the following formula:
S.I. = P × R × T,
where P = Principal, R = Rate of Interest in % per annum, and T = Time
Given,
Principal P = $3000
Rate of interest R = 4.25% = 4.25/100 = 0.0425
Time T = 3 years
Simple interest S.I. = P × R × T
= 3000 × 0.0425 × 3
= 127.5 × 3
S.I. = $382.5
Hence, Interest Bianca will earn in 3 years = $382.5

3, 3/4, 3/16 find the 6th term
The sixth term is [tex]\frac{3}{1024}[/tex] .
Given series : 3, [tex]\frac{3}{4}[/tex] , [tex]\frac{3}{16}[/tex] and so on.
We need to find the sixth term, so n = 6.
The given series is in Geometric Progression.
To find the [tex]n^{th}[/tex] term of a Geometric Progression,
[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]
a is the first term of any series. Here, a = 3
r is common ratio. Here, r = [tex]\frac{1}{4}[/tex]
According to the question,
[tex]a_{6}[/tex] = 3[tex](\frac{1}{4} )^{6-1}[/tex]
⇒ [tex]a_{6}[/tex] = 3 × [tex](\frac{1}{4} )^{5}[/tex]
⇒ [tex]a_{6}[/tex] = 3 × [tex]\frac{1}{1024}[/tex]
⇒ [tex]a_{6}[/tex] = [tex]\frac{3}{1024}[/tex]
So, the sixth term is [tex]\frac{3}{1024}[/tex].
If 1st number is a series of consecutive odd numbers is 6 less than the last one in the series, how many numbers are there is the series.
Let's call the first number in the series "x", and the last number in the series "y".
We know that the series is a consecutive series of odd numbers, and we also know that y is 6 less than the last number in the series.
Since the series is a consecutive series of odd numbers, we can say that the difference between any two consecutive numbers in the series is 2.
So, we can write an equation to represent this information:
y = x + (n-1) * 2
where n is the number of numbers in the series.
We also know that y is 6 less than the last number in the series, so we can add this information to our equation:
y = x + (n-1) * 2 - 6
To solve for n, we can rearrange the equation:
n = (y - x + 6) / 2 + 1
Now, if we know the value of x and y we can substitute them in the equation and find the number of terms in the series.

No statements are included in the question. Several observations are noted.
Step-by-step explanation:
y = 6x + 2
y = 6x + 1
y=mx+b is the equation for a straight line, where m is the slope and b the y-intercept.
Observations
1. These are both straight lines.
2. The slopes are both the same: +6. The lines are parallel.
3. Since they are parallel, they will never intersect (within the solar system)
4. The second line is one unit lower than the first: it's y-intercept is +1, comapared to +2 for the first.
5. Since they do not intercept, there is no solution for this system of equations.

What are periodic functions?If there is a positive real number P such that f(x + P) = f(x), for all x being real numbers, then the function y= f(x) is said to be periodic. The fundamental period of a function is the least value of the positive real number P. The period during which a function repeats itself is also known as the fundamental period of the function.
f(x + P) = f(x).
From the graph, we conclude it is a sine function.

Linear regression:
A fundamental and popular technique for predictive analysis is linear regression. Regression's overarching objective is to look at two things:
Accurately can a group of predictor variables forecast an outcome (dependent) variable.
Factors in particular, and how do they affect the outcome variable, are strongly predictive of both.
There are three main functions for regression analysis:
Assessing predictor power, foreseeing an outcome, and trend forecasting.
The regression equation's simplest version, y = c + b*x, has one dependent and one independent variable.

If Dr. Goldsman wants to buy the brand that covers the most area per pound, which brand should he buy?
The Best Lawn covers the most area per pound is better choice to buy.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Xtra Green covers 1/20 of an acre with 1/2 of a pound of fertilizer granules.
So, area per pound covered by Xtra Green
= (1/20) /(1/2)
= 1/20 x 2/1
= 1/10
= 0.1
Best Lawn covers 1/15 of an acre with 1/5 of a pound of fertilizer granules.
So, area per pound covered by Best Lawn
