what is a cubic polynomial function with zeros 3,3 and -3? show your work.
Answers
Answer:
Cubic polynomial function with zeros 3,3 and -3 is [tex]\mathbf{x^3-3x^2-9x+27=0}[/tex]
Step-by-step explanation:
We need to find a cubic polynomial function with zeros 3,3 and -3.
If zeros of polynomial are: 3,3,and -3
we can write:
x=3, x=3, x=-3
Or
We can write:
x-3=0, x-3=0, x+3=0
Now, we can write them as:
(x-3)(x-3)(x+3)=0
Multiplying the terms, we can find the polynomial:
[tex](x-3)(x-3)(x+3)=0\\(x(x-3)-3(x-3))(x+3)=0\\(x^2-3x-3x+9)(x+3)=0\\(x^2-6x+9)(x+3)=0\\x(x^2-6x+9)+3(x^2-6x+9)=0\\x^3-6x^2+9x+3x^2-18x+27=0\\x^3-6x^2+3x^2+9x-18x+27=0\\x^3-3x^2-9x+27=0[/tex]
So, cubic polynomial function with zeros 3,3 and -3 is [tex]\mathbf{x^3-3x^2-9x+27=0}[/tex]

Step-by-step explanation:
Given the data:
Dependent Independent
Variable Variable
Y ___ X
5 __ 15
7 __ 12
9 __ 10
11 __ 7
The general regression equation is of the form /
Y = B0 + BiX
Y = dependent variable ; B0 = intercept ` B1 = slope ; X = independent variable
Using calculator, the model obtained for the model is :
Y = 16.41176 - 0.7647x
Hence,
Least square estimate for b1 = - 0.7647
Least square estimate for b0 = 16.41176
Correlation Coefficient (R) = - 0.99705
The Coefficient of determination (R²) = - 0.99705^2 = 0.994108

A researcher measures water drawn from 52 points a city's system in order to check the claim that the average lead content in the city's water is no more than 7 micrograms per deciliter. She finds an average of 5 micrograms per deciliter. Please match each of these terms:
a. Population
b. Sample
c. Parameter
d. Statistic
1. the 52 water draws
2. 7 micrograms per deciliter
3. 5 micrograms per deciliter
4. 7/52 lead measurements
Answers
Answer:
a. Population - 1. the 52 water draws
b. Sample - 4. 7/52 lead measurements
c. Parameter - 2. 7 micrograms per deciliter
d. Statistic - 3. 5 micrograms per deciliter
Step-by-step explanation:
If the value is from a population, it is a parameter.
Otherwise, if the value is from a sample, it is a statistic.
A population is an entire group of people, or of something, while a sample is a small number of observations from this group.
In this question:
The entire population is the measures drawn from the 52 points in the city's system.
In the entire system, the average is no more than 7 micrograms per deciliter. This is a value from the entire population, so this is a parameter.
To found the average of 5 micrograms, she took 7 of these measurements. So the 7 measurements are the sample and the average os 5 micrograms is a statistic.
So the correct matching is:
a. Population - 1. the 52 water draws
b. Sample - 4. 7/52 lead measurements
c. Parameter - 2. 7 micrograms per deciliter
d. Statistic - 3. 5 micrograms per deciliter

y-4=m(x+3)
SECOND SET
y-1=m(x-2)
I am having a hard time interpreting your pasted copy of the possible answers. However, I can see that the slope is considered negative in all but the last answer.
Slope is defined as change-of-y divided by change-of-x...
m=(y-y1)/(x-x1)

m=(4-1)/(-3-2)

Answers
Answer:
7 0
Step-by-step explanation:
The next two numbers of the series is 27.5 and 44.
What is sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The complete question is:
Mr. jones asks his students to generate the next two numbers in the sequence beginning –5.5, 11, .... taquan suggests that the sequence is geometric and the next two numbers are –22 and 44. julia suggests that the sequence is arithmetic and the next two numbers are 27.5 and 44. which best explains which student is correct?
Given AP = -5.5, 11, ...
a = 5.5
d= 11 - (-5.5) =16.5
Now, a₃ = a₂ + d
a₃ = 11 + 16.5
a₃ = 27.5
and, a₄ = 27.5 + 16.5
a₄ = 44
Now, Taquan case:
a = -5.5
r = 110/-5.5
r = -2
now, a₃ = -2(11) = -22
a₄ = -2(-22) = 44

If A1

BRAINLIEST TO ANYONE
Answers
Answer:
25
Step-by-step explanation:
a1 = 9
a2 = a1 + 4
a2 = 9 + 4
a2 = 13
a3 = a2 + 4
a3 = 13 + 4
a3 = 17
a4 = 21
a5 = 21 + 4
a5 = 25
This can more easily be done by using this formula
L = a1 + (n - 1) * d
a1 = 9
n = 5
d = 4
L = 9 + (5 -1)*4
L = 9 + 4*4
L = 9 + 16
L = 25
