1.0, 5, 2
2.-3,-5,3,-1
5. 2 mult.2, -4
3.-5, 2 + i
4.-1, 2i
The polynomial expressions are P(x) = x(x - 5)(x - 2), P(x) = (x + 3)(x + 5)(x - 3)(x + 1), P(x) = (x + 5)(x² - 4x + 5) and P(x) = (x + 5)(x² + 4)
How to determine the polynomial expressionsZeros (1): 0, 5, 2
This means that
Roots: x = 0, x = 5 and x = 2
The equation can be represented as
P(x) = (x - root)
So, we have
P(x) = (x - 0)(x - 5)(x - 2)
Evaluate
P(x) = x(x - 5)(x - 2)
Zeros (2): 0, 5, 2
Here, we have
Roots: x = -3, x = -5, x = 3 and x = -1
Using the form in (a), we have
P(x) = (x + 3)(x + 5)(x - 3)(x + 1)
Zeros (3): 0, 5, 2
Here, we have
Roots: x = -5, x = 2 + i
Using the form used abov]e, we have
P(x) = (x + 5)(x - 2 - i)(x - 2 + i)
Expand
P(x) = (x + 5)((x - 2)² + 1)
So, we have
P(x) = (x + 5)(x² - 4x + 5)
Zeros (4): -1 and 2i
Here, we have
Roots: x = -1, x = 2i
Using the form used abov]e, we have
P(x) = (x + 1)(x - 2i)(x + 2i)
Expand
P(x) = (x + 5)(x² + 4)

ind the difference and write the resulting polynom (19x^(4)-17x-18)-(12x^(4)-8x+5)
The difference of the two polynomials is 7x^(4) - 9x - 23.
The difference of the two polynomials (19x^(4)-17x-18)-(12x^(4)-8x+5) can be found by subtracting the corresponding terms of the two polynomials.
Subtract the first term of the second polynomial from the first term of the first polynomial: 19x^(4) - 12x^(4) = 7x^(4)
Subtract the second term of the second polynomial from the second term of the first polynomial: -17x - (-8x) = -17x + 8x = -9x
Subtract the third term of the second polynomial from the third term of the first polynomial: -18 - 5 = -23
Write the resulting polynomial by combining the terms 7x^(4) - 9x - 23
Therefore, the difference of the two polynomials is 7x^(4) - 9x - 23.

What is a graph?Theoretical physicists use graphs to analytically chart or visually represent claims rather than values. A graph point typically depicts the relationship between any number of things. A specific type of non-linear train assembly made up of clusters and lines is known as a graph. Glue should be used to connect the networks, also referred as the boundaries. In this network, the nodes had the numbers 1, 2, 3, and 5, whilst edges had the numbers 1, 2, 3, and 4, as well as the numbers (2.5), (3.5), (4.5), and yet also (4.5). (4.5).
Here,
We can use the following method to determine the general term of an arithmetic series:
=> f(n) = a + (n-1)d
where the usual difference is "d" and "a" is the first term.
Since the series begins at 7, "a" is 7, as shown by the graph. Additionally, since each term reduces by 2, we can see that the common difference is 2.
Consequently, the following is the arithmetic sequence's stated rule:
A) f(n) = 7 - 2(n-1)

totaling more than $40,000 with 95% confidence to within 1%. Calculate the sample size you would
need. Use the sample proportion to estimate the population proportion
The sample size that would be required to estimate the confidence interval with a margin of error of 1% is given as follows:
n = 9604.
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The margin of error is modeled as follows:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
We have no estimate of the proportion, hence it is used as follows:
[tex]\pi = 0.5[/tex]
The margin of error is of M = 0.01, hence the sample size is obtained as follows:
[tex]0.01 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]
[tex]0.01\sqrt{n} = 1.96 \times 0.5[/tex]

Cλ=3,μ=10
DNone of these
The value of λ and μ for which the system of equations x+y+z=6,x+2y+3z=10 and x+2y+λz=μ are none of this. The correct answer is option D, None of these.
To find the value of λ and μ for which the system of equations has no solution, we can use the determinant method. The determinant of a system of equations is given by:
| a1 b1 c1 |
| a2 b2 c2 | = a1(b2c3 - b3c2) - b1(a2c3 - a3c2) + c1(a2b3 - a3b2)
| a3 b3 c3 |
For the given system of equations, the determinant is:
| 1 1 1 |
| 1 2 3 | = 1(2λ - 3μ) - 1(3 - 3) + 1(2 - 2)
| 1 2 λ |
Simplifying, we get:
2λ - 3μ = 0
For the system of equations to have no solution, the determinant must be equal to 0. Therefore, we need to find the values of λ and μ that satisfy the equation 2λ - 3μ = 0.

The solution to the system of equations using elimination is:
x = 1058/1890
y = 26/90
To solve this system of equations using elimination, we will add the two equations together and rearrange the terms.
2y = x - 5
2y = x + 5
Add the equations together:
2y + 2y = x - 5 + x + 5
4y = 2x + 0
Rearrange the terms:
4y - 2x = 0
We will now use this equation and the equation x + 2y = 13 to solve for x and y.
Substitute 4y - 2x = 0 into x + 2y = 13:
x + 2(4y - 2x) = 13
x + 8y - 4x = 13
Rearrange the terms:
5x + 8y = 13
Substitute 4y - 2x = 0 into 5x + 8y = 13:
5x + 8(4y - 2x) = 13
5x + 32y - 16x = 13
Rearrange the terms:
21x + 32y = 13
Divide by 21:
x + (32/21)y = 13/21
Rearrange the terms:
x = 13/21 - (32/21)y
Substitute x = 13/21 - (32/21)y into 4y - 2x = 0:
4y - 2(13/21 - (32/21)y) = 0
4y - (26/21) + (64/21)y = 0
Rearrange the terms:
(90/21)y = 26/21
y = (26/21) / (90/21)
y = 26/90
Substitute y = 26/90 into x = 13/21 - (32/21)y:
x = 13/21 - (32/21)(26/90)
x = 13/21 - (832/1890)
x = 1058/1890

To find the number of degrees for each part of the museum visitors graph, we need to know the total number of visitors for that month. Let's assume that the total number of visitors for the month is 10,000.
Age 18 and under:
Let's assume that the number of visitors aged 18 and under is 3,000. To find the number of degrees for this section of the graph, we need to use the formula: (Number of visitors in the age group / Total number of visitors) x 360 degrees. So, (3000/10000) x 360 = 108 degrees.
Age 19 – 44:
Let's assume that the number of visitors aged 19-44 is 5,000. Using the same formula as above, we get (5000/10000) x 360 = 180 degrees.
Age 45 – 64:
Let's assume that the number of visitors aged 45-64 is 1,500. Using the same formula as above, we get (1500/10000) x 360 = 54 degrees.
Age 65 and over:

A drawing of a 78-foot long building was built using a scale of 1in:8ft. What is the length of the drawing??
Answer:
Step-by-step explanation:
Given: Length of the building = 78 ft
Scale = 1 in : 8 ft
To find: Length of the building in the drawing
Now we have the scale where
8 ft = 1 inch
So using unit rule
1 ft = (1/8) in
So
78 ft = (1/8)(78) in = 9.75 inch
So length of the building in the drawing is 9.75 inch.
The length of the drawing is 9.75 inches.
To calculate the length of the drawing, find out how many inches correspond to 78 feet using the scale provided.
Since the scale is 1in:8ft, this means that 1 inch on the drawing represents 8 feet in real life.
To determine the length of the drawing, divide the length of the building by the scale factor:
Length of drawing = Length of building / Scale factor
Length of drawing = 78 ft / 8
Length of drawing = 9.75 inches
Hence, the drawing is 9.75 inches long.

Any point can be located using a Cartesian coordinate system or coordinate system, and that point can be plotted as an ordered pair (x, y) known as Coordinates. The origin, symbolized by the letter "O," is the point where the two number lines intersect. The horizontal number line is known as the X-axis, and the vertical number line is known as the Y-axis.
Given that the coordinates of Jason's house is (-4,-5). The coordinates of his school is (-10,-11).
The formula distance between two points (x₁, y₁) and (x₂, y₂) is √[(x₂ - x₁)² + (y₂ - y₁)²].
Here, x₁ = -4, y₁ = -5,x₂= -10, y₂ = -11
The distance between points is
√[(-10-(-4))² + (-11 - (-5))²]
=√(6² + 6²)
= √(36+36)
= √72
= 6√2
= 8.48
≈ 8 miles
