btract polynomials Subtract the polynomials. ((3)/(2)c^(2)-(4)/(3)c+9)-((1)/(6)c^(2)+(1)/(9)c+2)

Answers

Answer 1

Subtracting the polynomial (1/6)c² + (1/9)c + 2 from (3/2)c² - (4/3)c + 9 will result to the polynomial (4/3)c² + (-13/9)c + 7.

To subtract the polynomials, we need to subtract the corresponding terms. That is, we subtract the coefficients of the c² terms, the coefficients of the c terms, and the constant terms. The result will be a new polynomial. Here is the solution:

((3)/(2)c² - (4)/(3)c + 9) - ((1)/(6)c² + (1)/(9)c + 2)
= (3/2)c² - (4/3)c + 9 - (1/6)c² - (1/9)c - 2
= (3/2 - 1/6)c² + (-4/3 - 1/9)c + (9 - 2)
= (8/6)c² + (-13/9)c + 7
= (4/3)c² + (-13/9)c + 7

So the answer is (4/3)c² + (-13/9)c + 7.

On average, a clothing store gets 120 customers per day. What is the probability that the store will have fewer than 12 customers in the first two hours? (Assume the store is open 12 hours each day. Round your answer to four decimal places. )

Answers

The probability that clothing store have fewer than 12 customers in first 2 hours is 0.0003.

We know that, the store is open for 12 hours and gets an average of 120 customers per day, the expected number of customers in a 2-hour period can be calculated as:

The Expected number of customers in 2 hours = 120×(2/12) = 20 customers,

We, use the Poisson distribution to find the probability of having fewer than 12 customers in the first two hours.

The Poisson distribution is given by : P(X = k) = (e^(-λ) × λ^k)/k! ;

where X = random variable (the number of customers), λ = expected value of X (in this case, λ = 20), k = number of customers we want to calculate the probability for, and k! is the factorial of k.

To find the probability of having fewer than 12 customers in the first 2 hours, we need to calculate the probability for k = 0, 1, 2, ..., 11 and add up the probabilities.

So, we have,

⇒ P(X < 12) = e⁻²⁰×(20⁰/0!) + e⁻²⁰×(20¹/1!) + ... + e⁻²⁰×(20¹¹/11!);

On solving, We get,

⇒ P(X < 12) = 0.0003,

Therefore, the required probability is 0.0003.

What is the linear pair theorem?

In Mathematics, the linear pair theorem is sometimes referred to as linear pair postulate and it states that the measure of two angles would add up to 180° provided that they both form a linear pair.

This ultimately implies that, the measure of the sum of two adjacent angles would be equal to 180° when two parallel lines are cut through by a transversal.

According to the linear pair theorem, we have the following supplementary angles:

About 71 % of the residents in a town say that they are making an effort to conserve water or electricity. 110 residents are randomly selected.
1) Mean:
2) Standard Deviation:
3) What is the probability that the proportion of sampled residents who are making an effort to conserve water or electricity is greater than 80%?

Answers

About 71 % of the residents in a town say that they are making an effort to conserve water or electricity. 110 residents are randomly selected. The mean is 0.71. Standard Deviation is 0.043. The probability that the proportion of sampled residents who are making an effort to conserve water or electricity is greater than 80% is 0.0183.

1) Mean:
The mean of a proportion is simply the proportion itself, so the mean is 0.71.

2) Standard Deviation:
The standard deviation of a proportion is given by the formula:
σ = √(p(1-p)/n)
where p is the proportion, and n is the sample size. Plugging in the values given in the question:
σ = √(0.71(1-0.71)/110)
σ = 0.043

3) To find this probability, we need to use the normal distribution. We will use the z-score formula:
z = (x - μ) / σ
where x is the proportion we are interested in (0.8), μ is the mean (0.71), and σ is the standard deviation (0.043). Plugging in the values:
z = (0.8 - 0.71) / 0.043
z = 2.09
Using a z-table, we find that the probability of getting a z-score greater than 2.09 is 0.0183. So the probability that the proportion of sampled residents who are making an effort to conserve water or electricity is greater than 80% is 0.0183.

Answers

The simplified form of the left side of the equation is $2 \tan x$.

The left side of the equation can be simplified using the quotient and reciprocal identities. The quotient identity states that $\tan x = \frac{\sin x}{\cos x}$ and the reciprocal identity states that $\sec x = \frac{1}{\cos x}$ and $\csc x = \frac{1}{\sin x}$. By substituting these identities into the equation, we can simplify the left side:

\[ \begin{aligned} \frac{\sec x+\tan x \csc x}{\csc x} & =\frac{\frac{1}{\cos x}+\frac{\sin x}{\cos x} \cdot \frac{1}{\sin x}}{\frac{1}{\sin x}} \\ & =\frac{\frac{1}{\cos x}+\frac{1}{\cos x}}{\frac{1}{\sin x}} \\ & =\frac{2 \cdot \frac{1}{\cos x}}{\frac{1}{\sin x}} \\ & =\frac{2}{\cos x} \cdot \frac{\sin x}{1} \\ & =\frac{2 \sin x}{\cos x} \\ & =2 \tan x \end{aligned} \]

To finish the job using the unitary method, multiply the subsets measures taken from this microsecond section by two. In a nutshell, when a wanted thing is present, the characterized by a variable group but also colour groups are both eliminated from the unit technique. For instance, 40 changeable-price pencils would cost Inr ($1.01). It's conceivable that one nation will have complete control over the strategy used to achieve this. Almost all living things have a unique trait.

Here,

Magnus had to fill up his skiff with 6 gallons and 3 quarts of gas on Monday. We can observe that 1 quart is equivalent to 0.25 gallons to express this in decimal form:

=> 6 gallons 3 quarts = 6 + 3/4 = 6.75 gallons

Magnus used 6.75 litres of fuel on Monday as a result.

He required twice as much petrol on Saturday as he did on Monday:

=> 13.5 gallons from

=> 2 (6.75" gallons).

So on Saturday, he consumed 13.5 litres of fuel.

Overall, he employed:

The following illustrates an application of optimization using parabolas.
A study found that the cost C per pupil of operating a high school in a certain country depends on the number n of students enrolled. The cost is given by
C = 70,000 − 500n + n2 dollars per pupil.
What enrollment produces the minimum cost per pupil?
n = students

Answers

The minimum cost per pupil is $7,500 when 250 students are enrolled.

To find the minimum cost per pupil, we need to find the vertex of the parabola C = 70,000 − 500n + n². The vertex of a parabola in the form y = ax² + bx + c is given by the formula x = -b/2a. In this case, a = 1, b = -500, and c = 70,000.

Plugging these values into the formula, we get:
x = -(-500)/2(1) = 500/2 = 250

So the minimum cost per pupil occurs when n = 250 students are enrolled.

To find the minimum cost, we can plug n = 250 back into the equation for C:
C = 70,000 − 500(250) + (250)² = 70,000 - 125,000 + 62,500 = 7,500

we have proved that H ◃ G ↔ N(H) = G.

Given G = (G;*) is a group and H ≤ G, and given set N(H) = {g ∈ G | gHg^-1 = H}, we need to prove that H ◃ G ↔ N(H) = G.

First, let's assume that H ◃ G. This means that H is a normal subgroup of G. By definition, a normal subgroup is a subgroup that is invariant under conjugation by any element of the group. In other words, for any g ∈ G and h ∈ H, we have gHg^-1 = H. This is exactly the condition for an element to be in N(H), so we can conclude that N(H) = G.

Now, let's assume that N(H) = G. This means that every element of G is in N(H), which means that for any g ∈ G and h ∈ H, we have gHg^-1 = H. This is the definition of a normal subgroup, so we can conclude that H ◃ G.

What is the domain and range of y = log(-x + 3) - 1?

Answers

Answer:

The argument of the logarithmic function should be greater than zero.

Thus, for y = log(-x + 3) - 1 to be real-valued, we need:

-x + 3 > 0

or

x < 3

So, the domain of the function is all real numbers less than 3.

To find the range, let's consider the behavior of the logarithmic function.

As x approaches 3 from the left, the argument of the logarithm approaches zero from the negative side, which means the logarithm approaches negative infinity.

As x approaches negative infinity, the argument of the logarithm becomes very large and negative, which means the logarithm approaches negative infinity.

Therefore, the range of the function y = log(-x + 3) - 1 is all real numbers.

The given rectangle is not fully defined, as it is missing some measurements such as the length and width. Without this information, it is not possible to accurately calculate the perimeter of the rectangle.

However, assuming that the missing measurement is the width of the rectangle, then the expressions given by the five students would be:

2(3x + 4x + 3) = 14x + 6

2(6x + 6) + 2(4x + 6) = 20x + 24

Write a quadratic function f whose zeros are -2 and 9 .

Answers

To write a quadratic function f whose zeros are -2 and 9 , we have to factor the function by (x+2) and (x-9).

How to find the quadratic function of f?

A quadratic function is a second-degree mathematical function whose graph is a parabola. The general form of a quadratic function is given by f(x) = ax² + bx + c, where a, b and c are constants and a cannot be equal to zero. The variable x represents the input of the function and f(x) represents the output or result of the function. To find the quadratic function of f we first need to multiply these factors, like this:

f(x)= (x+2) (x-9)Expanding the product, we have:f(x)= x²-7x-18

So the quadratic function whose zeros are -2 and 9 is:

f(x)=x²-7x-18

15.F(x)=−529, F(x)=x^2+33; h(x)=∣x∣−233 ; g(x)=2x

Answers

The values of F(x), h(x), and g(x) when x=3 are 42, -230, and 6, respectively.

The given functions are F(x)=−529, F(x)=x^2+33, h(x)=∣x∣−233, and g(x)=2x.

To find the value of F(x) when x=3, we can substitute x=3 into the equation F(x)=x^2+33 and solve for F(x):
F(x)=x^2+33
F(3)=3^2+33
F(3)=9+33
F(3)=42

Similarly, to find the value of h(x) when x=3, we can substitute x=3 into the equation h(x)=∣x∣−233 and solve for h(x):
h(x)=∣x∣−233
h(3)=∣3∣−233
h(3)=3−233
h(3)=-230

And to find the value of g(x) when x=3, we can substitute x=3 into the equation g(x)=2x and solve for g(x):
g(x)=2x
g(3)=2(3)
g(3)=6

Therefore, the values of F(x), h(x), and g(x) when x=3 are 42, -230, and 6, respectively.

Suppose vector d = vector a - vector b where vector vector a has components ax = 4, ay = 5 and vector vector b has components bx = -4, by = -4

Answers

The vector representing D = A - B has following values,

1. x- component of vector D = 9 and y- component of vector D = 9.

2. Magnitude and direction of vector D is equal to 12.73 and 45° above the positive x-axis.

Here, Vector D= A-B  __(1)

Components of vector A are,

Ax=5

Ay=5

Components of vector B are,

Bx= -4,

By= -4

1. Subtract the x- and y-components of vector B from vector A, respectively by substituting in (1) we get,

Dx = Ax - Bx

    = 5 - (-4)

    = 5 + 4

    = 9

Dy = Ay - By

     = 5 - (-4)

     = 5 + 4

     = 9

2. Magnitude of vector D, use the Pythagorean theorem,

|D| = √(Dx² + Dy²)

    = √(9² + 9²)

    = √(162)

     ≈ 12.73

Direction of vector D, use trigonometry.

Angle θ represents vector D makes angle with positive x-axis is ,

θ = tan⁻¹(Dy / Dx)

   = tan⁻¹(9 / 9)

   = tan⁻¹(1)

    = 45°

Therefore, required value of the vectors are,

1. x- and y-components of vector D are 9 and 9, respectively.

2. Magnitude of vector D is 12.73, and direction is 45° above the positive x-axis.

The value for the quadratic equation is C(t) = t² + 3.

What is vertex?

When two lines or rays intersect and cross at one endpoint or vertex, a vertex angle is created. This angle, which is expressed in degrees, is occasionally confused with face angle. Two intersecting lines at the corner of a 2D object, such a polygon, generate a vertex angle. In 3D forms, however, multiple angles are conceivable since there are more than two lines.

The standard form of the quadratic function is given as:

C(t) = at² + bt + c

Using different values of t from the table we have:

a(-2)² + b(-2) + c = 7

a(-1)² + b(-1) + c = 4

a(0)² + b(0) + c = 3

Simplifying the equations we have:

4a - 2b + c = 7

a - b + c = 4

c = 3

Substituting the value of c = 3 in equation 2:

a - b = 1

Further solving the equation for a and b we have:

a = 1

b = 0

Hence, the equation for the quadratic equation is C(t) = t² + 3.
