the value 5 is a an upper bound for the zeros of the function shown below f(x)=x^4+x^3-11x^2-9x+18
A. TRUE
B. FALSE
Answers
Answer:
Answer to this question is TRUE.
Step-by-step explanation:
The graph of the function:
[tex]f(x)=x^4+x^3-11x^2-9x+18[/tex] is attached to the answer.
Clearly by looking at the graph we could see that the zeros of the function f(x) are -3, -2, 1 and 3.
All the zeros are distinct.
" Also upper bound of a number 'p' means the set of all those numbers which are greater than 'p' ".
Here 5 will be an upper bound for the zeros of the function f(x) since all the 4 zeros of f(x) are less than 5.
Hence, the given statement that the value 5 is an upper bound for the zeros of the function f(x) is TRUE.

What is the length of segment CE if AE = 15 inches and ED = 5 inches and EB = 3 inches?
A. 45 inches
B. 9 inches
C. 15 inches
D. 14 inches
Answers
We have to determine the length of segment CE if AE = 15 inches and ED = 5 inches and EB = 3 inches.
Since ,we can observe that AB and CD are chords intersecting at point E.
Therefore, by intersecting chord theorem which states:
" When two chords intersect each other inside a circle, the products of their segments are equal"
So, [tex] AE \times EB= CE \times ED [/tex]
[tex] 15 \times 3= CE \times 5 [/tex]
[tex] 45= CE \times 5 [/tex]
[tex] CE = \frac{45}{5} [/tex]
CE = 9 inches.
So, the measure of segment CE is 9 inches.
So, Option B is the correct answer.

Suppose y varies directly with x and y=-25 when x=5. find y when x=3
Answers
Final answer:
To solve for y when x = 3, we first determined the constant of proportionality (k) using the given values (y = -25 when x = 5). With k found to be -5, we then calculated y for x = 3 to find that y = -15.
Explanation:
The question asks us to find the value of y when x = 3 given that y varies directly with x and that y = -25 when x = 5. Because y is directly proportional to x, we can write the relationship as y = kx, where k is the constant of proportionality.
First, we solve for k:
Set up the equation based on the given information: y = kx
Substitute the known values: -25 = k(5)
Solve for k: k = -25 / 5 = -5.
Now that we have found k, we can use it to find y when x = 3:
Use the determined value of k: y = -5(3)
Multiply to find y: y = -15.
Therefore, when x = 3, y is -15.

The results of a survey indicate that between 76% and 84% of the season ticket holders are satisfied with their seat locations.
What is the survey’s margin of error?
Enter your answer in the box. ± ___ %
The answer goes on the underscores
Answers
[tex]C.I.=\hat{p}\pm M.E.[/tex]
where: [tex]\hat{p}[/tex] is the sample proportion, which is midway between the two intervals and M.E. is the margin of error which is the difference between each of the intervals and the sample proportion.
i.e.
[tex]\hat{p}= \frac{76+84}{2} \% \\ \\ = \frac{160}{2} \%=80\%[/tex]
Therefore, the margin of error is 4%.
Final answer:
The margin of error for the survey, given a range between 76% and 84% satisfaction for seat locations, is calculated to be ±4%.
Explanation:
The margin of error in a survey indicates how much the survey results might differ from the actual opinions of the total population.
In this case, the survey indicates a satisfaction range between 76% and 84% for seat locations among season ticket holders.
The margin of error is half of the width of the range, which is the difference between the upper and lower percentage bounds of the confidence interval divided by two.
To calculate the margin of error, subtract the lower percentage (76%) from the upper percentage (84%) and then divide by 2. That is, (84 - 76) / 2 = 8 / 2 = 4.
Thus, the margin of error for the survey is ±4%.
In a circle, a 225 degrees sector has area 490pi in2. What is the radius of the circle?
Answers
area of a sector=(∅*pi/360°)*r²--------> when ∅ is in degree
r=√[360°*(area of a sector)/(∅*pi)]
area of a sector=(∅/2)*r²--------> when ∅ is in radians
r=√[2*(area of a sector)/∅]
let's calculate the radius of the two ways
1) r=√[360°*(area of a sector)/(∅*pi)]
area of a sector=490*pi in²
∅=225°
r=√[360°*(490*pi)/(225°*pi)]-------> r=√784-----> r=28 in
2) r=√[2*(area of a sector)/∅]
area of a sector=490*pi in²
∅=225°-----> convert to radians-----> ∅=225°*pi/180-----> ∅=1.25*pi
r=√[2*(490*pi)/(1.25*pi)]----> r=√[980/1.25]---> r=√784----> r=28 in
the answer is
the radius is 28 in

The original vertices of a quadrilateral are (-2,3), (4,6), (4,2), and (3, -2). After a transformation, the new coordinates are (-1,1.5), (2,3),(2,1), and (1.5,-1). Are the two images similar? Justify your answer.
A) no; The transformation is not rigid; therefore, the quadrilaterals are not similar.
B) no; The transformation is a translation which only results in the size of the quadrilaterals being preserved.
C) yes; This is a rigid transformation which preserves angle measurement and size of the original quadrilateral.
D) yes; The transformation is a dilation which results in similar quadrilaterals by preserving angle measurements.
Answers
The answer would be D) yes; The transformation is a dilation that results in similar quadrilaterals by preserving angle measurements.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
The original vertices of a quadrilateral are (-2,3), (4,6), (4,2), and (3, -2).
After a transformation, the new coordinates are (-1,1.5), (2,3),(2,1), and (1.5,-1).
As we know that dilation is a process for creating similar figures by changing the size.
This means that the two images are similar, as they have the same shape and size, despite having different positions and orientations in the coordinate plane.
Hence, the given transformation is a dilation that results in similar quadrilaterals by preserving angle measurements.

The prime factorization of 18 is 2 x 3², dividing 18 first by 2 and then by 3 twice.
Explanation:The prime factorization of a number represents that number written as the product of its prime factors. Let's take 18 as an example. First, we will find the smallest prime number that can divide 18, which is 2. When 18 is divided by 2, the quotient is 9. Then, we continue to divide 9 by the smallest possible prime number, which is 3. We can divide 9 by 3 two more times. Therefore, the prime factorization of 18 is 2 x 3², where 2 and 3 are the prime factors and ² is an exponent indicating that 3 is a factor twice.
