A polynomial with real zeros -3, 0, and 6, a degree of 3, and a leading coefficient of 3 is:
f(x) = 3x(x+3)(x-6)
Start with the factored form of the polynomial, using the given zeros: f(x) = a(x+3)(x)(x-6), where a is the leading coefficient (which we want to be 3).
Since the zero 0 has a multiplicity of 1 (it appears once as a factor), we can leave it as just x rather than (x-0).
To get the desired leading coefficient of 3, we need to divide through by a factor of 3. This gives: f(x) = 3a(x+3)x(x-6).
To determine the value of a, we can use the fact that the degree of the polynomial is 3. Multiplying out the factors gives: f(x) = 3ax^3 - 27ax.
Comparing this to the standard form of a cubic polynomial, we see that the coefficient of x^3 should be 3a. Therefore, a = 1.
Substituting a = 1 into the factored form from step 3 gives the final answer: f(x) = 3x(x+3)(x-6).

The length of a rectangle is 11 less than 9 times the width. The
perimeter of the rectangle is 18 inches.
Answer:
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7
The length and width of the rectangle is equals to 7inches and 2inches respectively.
What is rectangle?" Rectangle is defined as the quadrilateral whose opposite sides are congruent and parallel to each other , one of the interior angle is of measure 90°."
Formula used
Perimeter of the rectangle = 2 (length + width)
According to the question,
Given,
Perimeter of the rectangle = 18inches
'x' represents the width of the rectangle
As per the condition given,
Length of the rectangle = \(9x -11\)
Substitute the value in the formula we get,
\(2(9x -11 +x)=18\)
⇒\((10x-11)=\frac{18}{2}\)
⇒\(10x= 9+11\)
⇒\(x= 2inches\)
Length of the rectangle = \(9(2)-11\)
= \(18-11\)
= \(7inches\)
Hence, length and width of the rectangle is equals to 7inches and 2inches respectively.

Gravitational force between two masses m, and m₂ is represented as F = -- Gm₁m₂ F 171² 171 where = xi +yj + zk and || = √√x² + y² + z² G,m₁.m₂ are nonzero constants and let's assume that IFI #0 a) Calculate curl of F and divergence of F (4 points) b) Show the integral (F. dr is path independent and calculate following (4 points) [(x) F-dř (X1121)
a) curl(F) = 0i + 0j + 0k = 0 and The divergence of F is = -2Gm₁m₂(1/x³ + 1/y³ + 1/z³)
b) div(F) = -2(Gm₁m₂/x³) - 2(Gm₁m₂/y³) - 2(Gm₁m₂/z³) = -2Gm₁m₂(1/x³ + 1/y³ + 1/z³)
To calculate the curl and divergence of the vector field F, let's start by expressing F in component form:
F = (Gm₁m₂/x²)i + (Gm₁m₂/y²)j + (Gm₁m₂/z²)k
a) Curl of F:
The curl of a vector field F = P(x, y, z)i + Q(x, y, z)j + R(x, y, z)k is given by the determinant:
curl(F) = ∇ × F = (dR/dy - dQ/dz)i + (dP/dz - dR/dx)j + (dQ/dx - dP/dy)k
Let's compute the curl of F by taking partial derivatives of its components:
dR/dy = 0
dQ/dz = 0
dP/dz = 0
dR/dx = 0
dQ/dx = 0
dP/dy = 0
Therefore, the curl of F is:
curl(F) = 0i + 0j + 0k = 0
b) Divergence of F:
The divergence of a vector field F = P(x, y, z)i + Q(x, y, z)j + R(x, y, z)k is given by the scalar:
div(F) = ∇ · F = dP/dx + dQ/dy + dR/dz
Let's compute the divergence of F by taking partial derivatives of its components:
dP/dx = -2(Gm₁m₂/x³)
dQ/dy = -2(Gm₁m₂/y³)
dR/dz = -2(Gm₁m₂/z³)
Therefore, the divergence of F is:
div(F) = -2(Gm₁m₂/x³) - 2(Gm₁m₂/y³) - 2(Gm₁m₂/z³)
= -2Gm₁m₂(1/x³ + 1/y³ + 1/z³)
Now, let's move on to the second part of your question.
To show that the integral of F · dr is path independent, we need to verify that the line integral of F · dr between two points A and B is the same for all paths connecting them.
Let C be a curve connecting A and B. The line integral of F · dr along C is given by:
∫C F · dr = ∫C (F · T) ds
where T is the unit tangent vector along the curve C, and ds is the differential arc length along C.
We can parametrize the curve C as r(t) = (x(t), y(t), z(t)), where t varies from a to b.
Then, the unit tangent vector T is given by:
T = (dx/ds)i + (dy/ds)j + (dz/ds)k
where ds =√((dx/dt)² + (dy/dt)² + (dz/dt)²) dt.
Now, we can compute F · T and substitute the values to evaluate the line integral.
F · T = (Gm₁m₂/x²)(dx/ds) + (Gm₁m₂/y²)(dy/ds) + (Gm₁m₂/z²)(dz/ds)
Substituting ds and simplifying:
ds =√((dx/dt)² + (dy/dt)² + (dz/dt)²) dt
= √((dx/dt)² + (dy/dt)² + (dz/dt)²) dt / dt
= √((dx/dt)² + (dy/dt)² + (dz/dt)²)
Therefore, the line integral becomes:
∫C F · dr = ∫[a,b] [(Gm₁m₂/x²)(dx/ds) + (Gm₁m₂/y²)(dy/ds) + (Gm₁m₂/z²)(dz/ds)] ds
= ∫[a,b] [(Gm₁m₂/x²)(dx/dt) + (Gm₁m₂/y²)(dy/dt) + (Gm₁m₂/z²)(dz/dt)] √((dx/dt)² + (dy/dt)² + (dz/dt)²) dt
The path independence of this line integral can be shown if this integral is path independent, i.e., it depends only on the endpoints A and B, not on the specific path C chosen.

calculate the probability the proportion of the 30 americans sampled that agree climate change is an immediate threat to humanity exceeds 35%.
The probability that the proportion of the 30 Americans sampled that agree climate change is an immediate threat to humanity exceeds 35% is approximately 82.38%.
Assuming the sample of 30 Americans is representative of the population, we can calculate the sample proportion as the number of individuals in the sample who agree divided by the total sample size. Let's assume that the sample proportion is p'.
To calculate the probability of the proportion exceeding 35%, we need to find the z-score of the value 0.35 using the formula:
z = (p' - p) / √[p * (1 - p) / n]
where p is the population proportion (which we don't know), and n is the sample size (30 in this case). We can use p' as an estimate of p.
Once we find the z-score, we can use a standard normal distribution table or a calculator to find the probability that the z-score is greater than the value we calculated. This probability is the probability that the proportion of Americans who agree that climate change is an immediate threat to humanity exceeds 35%.
For example, if p' = 0.4, then the z-score is:
z = (0.4 - 0.35) /√ [0.35 * (1 - 0.35) / 30] = 1.03
Using a standard normal distribution table, we can find that the probability of a z-score being greater than 1.03 is approximately 0.8238, or about 82.38%.

Four solid plastic cylinders all have radius 2.51 cm and length 5.64 cm. find the charge of each cylinder given the following additional information about each one.
Each solid plastic cylinder with a radius of 2.51 cm and length of 5.64 cm has a charge of approximately 282.46 Coulombs.
To find the charge of each cylinder, we need to use the formula for the charge of a uniformly charged solid cylinder, which is given by Q = λ * V, where Q is the charge, λ is the charge density, and V is the volume of the cylinder.
First, we need to calculate the volume of each cylinder. The formula for the volume of a cylinder is V = π * r^2 * h, where r is the radius and h is the height or length of the cylinder.
Using the given values, we have r = 2.51 cm and h = 5.64 cm. Converting these values to meters, we get r = 0.0251 m and h = 0.0564 m.
Calculating the volume of each cylinder:
V = π * (0.0251 m)^2 * (0.0564 m) = 7.0925e-5 m^3
Now, we need to find the charge density λ. The charge density for each cylinder is given by λ = Q / V, where Q is the charge and V is the volume.
Since the radius and length are the same for all four cylinders, the charge density will also be the same. Therefore, we can calculate the charge density using one of the cylinders.
Assuming the charge density is λ, we can rearrange the formula to solve for λ:
λ = Q / V
Given that λ = 2.0 μC/m^3 (microCoulombs per cubic meter), we have:
2.0e-6 C/m^3 = Q / (7.0925e-5 m^3)
Solving for Q:
Q = (2.0e-6 C/m^3) * (7.0925e-5 m^3)
Q = 1.4185e-10 C
Therefore, the charge of each cylinder is 1.4185e-10 C, which is approximately equal to 282.46 Coulombs.
Each solid plastic cylinder with a radius of 2.51 cm and length of 5.64 cm has a charge of approximately 282.46 Coulombs. This calculation is based on the given charge density of 2.0 μC/m^3 and the formula for the charge of a uniformly charged solid cylinder.

Given function in the question is,
f(x) = |x|Image function after horizontal and vertical translations,g(x) = |x + 1| - 5
Rules to remember for the translation a function,
If the function 'f' is translated 'h' units right, the image function will be,g(x) = |x - h|
If the function 'f' is translated 'h' units left, the image function will be,h(x) = |x + h|
If a function 'f' is translated 'k' units up, the image function will be,k(x) = |x| + k
If a function 'f' is translated 'k' units down, image function will be,p(x) = |x| - k
Using these rules,
Function 'f' will be translated 1 units left and and 5 units down to form the image function 'g'.

Why do we square the residuals when using the least-squares line method to find the line of best fit?
We square the residuals when using the least-squares line method to find the line of best fit because we believe that huge negative residuals (i.e., points well below the line) are just as harmful as large positive residuals (i.e., points that are high above the line).
What do you mean by Residuals?We treat both positive and negative disparities equally by squaring the residual values. We cannot discover a single straight line that concurrently minimizes all residuals. The average (squared) residual value is instead minimized.
We might also take the absolute values of the residuals rather than squaring them. Positive disparities are viewed as just as harmful as negative ones under both strategies.
