Use a generating function for modeling the number of different selections of r hot dogs when there are four types of hot dogs.

Answers

Answer 1

Using generating function number of different selections of r hot dogs when there are four types of hot dogs are g(x) = ( 1/(1-x) )⁴.

What is Generating function?

For a sequence a₀,a₁,...,aₙ,... the corresponding generating function f(x) is the sequence

f(x)=a₀+a₁x+...+aₙxₙ+...= ∑aᵢxᵢ , 0 ≤ i ≤ ∞

Since here we have 4 types of hot dogs, from which we need to select "r" hot dogs, we would use a generating function as follows:

There can be any number of selections from any pile of hot dogs ( repitions is allowed). therefore, from each pile, you could pick up 1 or 2 or 3 or ... hot dogs. The same would go for all types of hot dogs. Therefore ,the generating function for the same would be,

g(x) = (1 + x + x² + x³ + x⁴ + ...)(1 + x + x² + x³ + x⁴ + ...)(1 + x + x² + x³+ x⁴ + ...)(1 + x + x² + x³+ x⁴+ ...)

Therefore, g(x) = (1 + x + x² + x³ + x⁴ + ...)⁴

This is an infinite geometric series, which can be solved to give the sum: g(x) = ( 1/(1-x) )⁴. Therefore, our required the coefficient of xʳ in (1/ (1-x) )⁴.

James T-shirt business uses the demand function P = -Q+31 and the supply function P = Q-17. According to these functions, what will the
equilibrium point (P.Q) be for James T-shirt business?

Answers

The equilibrium point for James T-shirt business is (P, Q) = (7, 24).

To find the equilibrium point (P, Q) for James T-shirt business

we need to set the demand function equal to the supply function and solve for the values of P and Q.

Demand function: P = -Q + 31

Supply function: P = Q - 17

Setting them equal:

-Q + 31 = Q - 17

Adding Q to both sides and subtracting 31 from both sides:

2Q = 48

Dividing both sides by 2:

Q = 24

Now, we can substitute this value of Q into either the demand or supply function to find the corresponding value of P.

P = Q - 17

P = 24 - 17

P = 7

Therefore, the equilibrium point for James T-shirt business is (P, Q) = (7, 24).

Answers

The area of the rectangle is 2w² + 3w

What is area of rectangle?

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel.

The area of a rectangle is expressed as;

A = l× w

where l is the length and w is the width

the length is 3 more that twice the width

l = 3 + 2w

A = l × w

A = (3 + 2w)w

A = 3w + 2w²

Every ideal of S is principal when f:R⇒S be a surjective homomorphism of rings with identity.

In a homomorphism, corresponding elements of two systems behave very similarly in combination with other corresponding elements. For example, let G and H be groups. The elements of G are denoted g, g′,…, and they are subject to some operation ⊕.

In algebra, a homomorphism is a structure-preserving map between two algebraic structures of the same type (such as two groups, two rings, or two vector spaces). The word homomorphism comes from the Ancient

We know that,

Since f is sufficient homomorphism.

So, f⁻¹(I) is an ideal of R.

Since R is PID so ∈ r ∈ R such that

MARS On Mars, the gravity acting on an object is less than that on Earth. On Earth, a golf ball hit with an initial upward velocity of 26 meters per second will hit the ground in about 5.4 seconds. The height h of an object on Mars that leaves the ground with an initial velocity of 26 meters per second is given by the equation h=−1.9t2+26t
. How much longer will it take for the golf ball hit on Mars to reach the ground? What is the maximum height of the golf ball on Mars? Round your answer to the nearest tenth.



It takes about
seconds longer for the golf ball hit on Mars to reach the ground.

The maximum height of the golf ball on Mars is about
meters.

Answers

The maximum height of the golf ball on Mars is approximately 89.1 meters.

To find out how much longer it will take for the golf ball hit on Mars to reach the ground, we need to determine the time it takes for the height (h) to reach zero.

We can set the equation for height (h) equal to zero and solve for time (t):

\(-1.9t^2 + 26t = 0\)

Factoring out a common factor of t gives us:

\(t(-1.9t + 26) = 0\)

Using the zero product property, we have two possible solutions:

t = 0 (starting time)

\(-1.9t + 26 = 0\)

Solving the second equation:

\(-1.9t + 26 = 0\)

\(-1.9t = -26\)

\(t = \frac{-26}{-1.9}\)

\(t \approx 13.68\) seconds

So, it will take approximately 13.68 seconds for the golf ball hit on Mars to reach the ground.

Since the initial time was 0 seconds (starting time), the additional time it takes for the ball to reach the ground on Mars is approximately

\(13.68 - 0 = 13.68\) seconds.

To find the maximum height of the golf ball on Mars, we can determine the vertex of the quadratic equation.

The vertex of a quadratic equation in the form of \(h = at^2 + bt + c\) is given by the formula:

\(t_{vertex}=\frac{-b}{(2a)}\)

In this case, a = -1.9 and b = 26. Substituting the values:

\(t_{vertex}= \frac{ -26}{(2 \times -1.9)}\)

\(t_{vertex}\approx 6.8421 seconds\)

Now, substituting this value of t_vertex back into the equation

\(h = -1.9t^2 + 26t\):

\(h = -1.9(6.8421)^2 + 26(6.8421)\\\)

\(h \approx -1.9(46.764) + 177.948\)

\(h \approx -88.852 + 177.948\)

\(h\approx 89.096 meters\)

So, the maximum height of the golf ball on Mars is approximately 89.1 meters.

First translate \(5\frac{1}{3}\) into an improper fraction.

\(5\frac{1}{3}\) = \(\frac{16}{3}\)

So that means: \(\frac{3}{4}\) ÷ \(\frac{16}{3}\).

Now you have to switch \(\frac{16}{3}\) to its reciprocal to multiply.

Find the area of a trapezoid with bases of 16 feet and 10 feet and a height of 3 feet. 39 ft2 78 ft2 240 ft2 480 ft2

Answers

Answer: 39 ft2

Step-by-step explanation:

The area of the trapezoid is 39 square feet.

To find the area of a trapezoid, you can use the formula:

Area = (1/2) × (base1 + base2) × height

Given that the bases of the trapezoid are 16 feet and 10 feet, and the height is 3 feet, we can substitute these values into the formula:

Area = (1/2) × (16 + 10) × 3

Area = (1/2) × 26 × 3

Area = (1/2) × 78

Area = 39 ft^2

Therefore, the area of the trapezoid is 39 square feet.

The length of a rectangle is twice its width. Find its lenght and width, if its perimeter is 7 1/3 cm.

Answers

The length of the rectangle is twice its width. If its perimeter is 7 1/3 cm, its length will be 22/9 cm, and the width is 11/9 cm.

Let's assume the width of the rectangle is "b" cm.

According to the given information, the length of the rectangle is twice its width, so the length would be "2b" cm.

The formula for the perimeter of a rectangle is given by:

Perimeter = 2 * (length + width)

Substituting the given perimeter value, we have:

7 1/3 cm = 2 * (2b + b)

To simplify the calculation, let's convert 7 1/3 to an improper fraction:

7 1/3 = (3*7 + 1)/3 = 22/3

Rewriting the equation:

22/3 = 2 * (3b)

Simplifying further:

22/3 = 6b

To solve for "b," we can divide both sides by 6:

b = (22/3) / 6 = 22/18 = 11/9 cm

Therefore, the width of the rectangle is 11/9 cm.

To find the length, we can substitute the width back into the equation:

Length = 2b = 2 * (11/9) = 22/9 cm

So, the length of the rectangle is 22/9 cm, and the width is 11/9 cm.

According to this rule:

Approximately 68% of scores lie within 1 standard deviation of the mean.

Approximately 95% of scores lie within 2 standard deviations of the mean.

Approximately 99.7% of scores lie within 3 standard deviations of the mean.
