Which of the following is not a factor of the polynomial p(x) = x³ - 23x² + 142x - 120?
Options :
A(x - 1)
B(x - 10)
C(x - 5)
D(x - 12)
no spam answers and explain how you got the solution.
Answer:
The correct answer is C- (X-5)Solution
Given -
polynomial p(x) = x³ - 23x² + 142x - 120
Now see the coefficients
coefficient of x³ is 1 x² is -23 x is 142 and then -120
when you'll add this coefficients
i.e.
1-23+142-120=0
When sum of the coefficient turn out 0 then x = 1
using x=1, x-1 = 0
devide the given polynomial p(x) = x³ - 23x² + 142x - 120 by x-1 you'll get rest two factors hence

A painting is going to be reprinted as posters. The dimensions of the painting are 3/4 of a yard to and 1/2 of a yard wide, The poster company is trying to determine how big to make the poster For each yard of width, how many yards of height are needed??
Answer:
3/8 yards
Step-by-step explanation:
3/4 yard tall and 1/2 yard wide
Multiply the two fractions
3/4 (1/2)
= 3/8 yards
If the width of the rectangular painting is one unit then the height of the painting will be 3/8 yards. Then the correct option is A.

For which weight of clothing is the ratio of weight to dye different from the other ratios?
21 pounds
42 pounds
84 pounds
105 pounds
Answer: The answer is 42
Step-by-step explanation:
I did the test too :)
The weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.
To determine which weight of clothing has a ratio of weight to dye different from the other ratios, we need to compare the ratios for each weight.
Let's calculate the ratios for each weight of clothing by dividing the weight of clothing (in pounds) by the cups of dye:
For 21 pounds of clothing: 21 pounds / 3 cups = 7 pounds per cup
For 42 pounds of clothing: 42 pounds / 9 cups = 4.67 pounds per cup
For 84 pounds of clothing: 84 pounds / 12 cups = 7 pounds per cup
For 105 pounds of clothing: 105 pounds / 15 cups = 7 pounds per cup
From the calculations, we can see that for weights of 21 pounds, 84 pounds, and 105 pounds of clothing, the ratios of weight to dye are the same, which is 7 pounds per cup. However, the ratio for 42 pounds of clothing is different, which is 4.67 pounds per cup.
Therefore, the weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

After how many years will an investment of $100 compounded quarterly at 6% annually be worth $450? (round to the nearest year)
Answer:
The investment will be worth $450 after 25.255 years which is about 25 years and 3 months.
Step-by-step explanation:
You have to use the following formula to calculate the number of years:
t=ln(A/P) / n(ln(1 + r/n)), where:
t=time in years
A=Accrued amount=450
P=Principal amount=100
n=number of compounding periods per time period=4
r=interest rate=0.06
Now, you can replace the values in the formula:
t=ln(450/100)/4(ln(1+(0.06/4)))
t=ln(4.5)/4(ln(1.015))
t=1.50/0.059
t=25.255
According to this, the answer is that the investment will be worth $450 after 25.255 years which is about 25 years and 3 months.

If line segment AB,A(9,3) and B(-6,-9), what scale factor was used to dilate if new line is at A'(3,1) and B'(-2,-3)?
Answer:
The scale factor is 1/3
Step-by-step explanation:
Here, we want to get the scale factor used in dilating the original segment
As we can see;
(9,3) turned to (3,1)
looking at this , we can see that both coordinate values were divided by 3
So what this mean is that the particular scale factor used is reduction by 1/3
This is the case with the other point as (-6,-9) turned to (-2,-3)

Can you give me an example on why it’s not foolish to fear ?
Answer:
It is not foolish to fear—it is a matter of survival. The physical responses we have to objects or situations that we fear are often grouped together and characterized as a “fight or flight” instinct. Something alarms you, and instantly your brain causes a number of chemicals to be released into your bloodstream.
Answer:
Fear is already a part of human nature. In fact, fear is used as a defense mechanism of our ancestors long time ago. They used to live on caves, jungles, and not so sturdy shelters that would make them vulnerable enough to different predators. Thus having the feeling of fear saves them by backing down and to retreat unto safer places. Therefore I can say that it's not foolish to fear since it's already a part of us human beings. Even the bravest persons in the world have their own fears too. We can't just separate it from ourselves and let's just embrace it and try to do something to lessen it.

EASY- Han has to build the figure below, which will serve as a counterweight, for his robotics project. Find the VOLUME of the finished object assuming it is empty inside.
Given:
A combined figure of a triangular prism and a cuboid.
To find:
The volume of the finished object assuming it is empty inside.
Solution:
From the given figure it is clear that the dimensions of the cuboid are 6 cm, 8 cm and 5 cm.
So, the volume of the cuboid is:
[tex]V_1=length\times width\times height[/tex]
[tex]V_1=6\times 8\times 5[/tex]
[tex]V_1=240[/tex]
The volume of the cuboid is 240 cubic cm.
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Thus, the base area of the triangular prism whose base is 8 cm and height 4 cm, is:
[tex]B=\dfrac{1}{2}\times 8\times 4[/tex]
[tex]B=16[/tex]
The volume of a triangular prism is:
[tex]V_2=Bh[/tex]
Where, B is the base area and h is the height of the prism.
The base area of the triangular prism is 16 square cm and the height is 5 cm. So, the volume of a triangular prism is:
[tex]V_2=16(5)[/tex]
[tex]V_2=80[/tex]
Now, the volume of the given figure is:
[tex]V=V_1+V_2[/tex]
[tex]V=240+80[/tex]
[tex]V=320[/tex]
Hence, the volume of the finished object is 320 cubic cm.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 8 out of the last 18 children to enroll at the daycare center were elementary school students,
We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:
= 8/18
= 4/9
This means that 4 out of every 9 children enrolled were elementary school students.
If we want to predict how many of the next 9 children to enroll will be elementary school students,
We can use this ratio:
4/9 of 9 children
= (4/9) x 9
= 4
Therefore,
We would expect that 4 of the next 9 children to enroll will be elementary school students.
