(a) The solution of the seasonal-growth model is

P(t) = P0[tex]e^{(k/r sin(rt))}[/tex]

(b) After solving we get [tex]\lim_{t \to \infty} P(t)[/tex] = NONE . As, t approaches to infinity

(a) To solve the differential equation DP/dt = kPcos(rt-[tex]\theta[/tex]),

The variables can be split apart and integrat:

∫(1/P) dP = ∫k cos(rt-[tex]\theta[/tex] ) dt

ln|P| = (k/r)sin(rt- [tex]\theta[/tex] ) + C

where

C is the constant of integration.

By solving for P, we get:

P(t) = [tex]e^{(k/r sin(rt- \theta ) + C)}[/tex]

We can determine the value of C by using the initial condition P(0) = P0:

P(0) = [tex]e^{(k/r sin(- \theta) + C)}[/tex]= P0

C = ln(P0) - (k/r)sin(-[tex]\theta[/tex] )

C = ln(P0) + (k/r)sin([tex]\theta[/tex] )

By substituting this into the expression for P(t), we get:

P(t) = [tex]e^{(k/r sin(rt-\theta) + ln(P0) + (k/r)sin(\theta))}[/tex]

By simplifying, we get:

P(t) = P0[tex]e^{(k/r sin(rt-\theta) + k/r sin(\theta))}[/tex]

P(t) = P0[tex]e^{(k/r sin(rt))}[/tex]

(b) We must take into account the behavior of sin(rt) as t approaches infinity in order to determine the limit of P(t) as t approaches infinity. Sin(rt) will fluctuate between -1 and 1 as t grows because the sine function oscillates between -1 and 1.

As a result, the term [tex]e^{(k/r sin(rt))}[/tex] will bounce between [tex]e^{(-k/r)}[/tex] and [tex]e^{(k/r)}[/tex] as t approaches infinity, but it won't converge to a single value.

As a result, there is no P(t) limit as t approaches infinity.

Hence, the answer is:

[tex]\lim_{t \to \infty} P(t)[/tex] = NONE.

Therefore , the solution of the given problem of cardinality comes out to be A×B×C is 3 .

A's cardinality is equivalent to its element count if A has a finite amount of elements. Say |A|=5 if A=2, 4, 6, 8, 10. The outcome of a numbering process is referred to as "cardinality". A set's cardinality is determined by the number of components in it. For illustration, the group 1, 2, 3, 4, and 5 has a greater cardinality of five than the set 1, 2, 3, and 5, each of which has an attributes of three.

Here,

a)

I "Chinese New Year of 2023" has one cardinal element, making it one-dimensional.

ii) Since there are three elements in S and each element can either be included in a subset or not, the power set P(S) of S=1,,apple has 23 = 8 elements.

iii) xRx2=3 has two components because the squares of two real numbers, 3 and -3, are both 3.

iv) Since "0" is regarded as one element and there are five other distinct elements in the collection,  {{0,1,2},3,4,5,∅,{{0}}}  has six elements.

b)

=> A={0,1,2}, B={apple}, and C={apple}

The set difference between C and A is only the element 0, which is absent from C, so A=apple0,1,2=apple.

Consequently, A, B, and C include the following components:

the perimeter of D'E'F is 5 times larger than the perimeter of DEF.

If the scale from DEF to D'E'F is 5:1, then the corresponding side lengths are multiplied by a factor of 5 when going from DEF to D'E'F. This means that if the perimeter of DEF is P, then the perimeter of D'E'F is 5P.

To see why this is true, consider the perimeter of DEF:

P = DE + EF + FD

The correct answer is C. 6 seconds.

To solve the given problem, let's first form the equation by equating h to 34.48 (since this is the height we are looking for):34.48 = 14.5 cos(2πt/5) + 30Next, let's subtract 30 from both sides:4.48 = 14.5 cos(2πt/5)Now, let's divide both sides by 14.5:cos(2πt/5) = 4.48/14.5Now we can solve for t:2πt/5 = cos^-1(4.48/14.5)t = (5/2π) cos^-1(4.48/14.5)Using a calculator, we can evaluate this expression to get t ≈ 3.59 seconds. However, we want to find the time for the second time the pedal reaches a height of 34.48 inches. Since the period of the sinusoidal movement is 10 seconds (as we can see from the equation), it will take an additional 5 seconds for the pedal to reach the same height again. Therefore, the total time for the pedal to reach a height of 34.48 inches for the second time is:t = 3.59 + 5 = 8.59 seconds Rounding to the nearest second, we get an answer of C. 6 seconds. Therefore, the correct answer is C. 6 seconds.

The price per unit that yields maximum revenue is $400.

We can start by finding the demand function for the product. Since the demand is assumed to be linear, we can use two data points to find the equation of the line:

(40, 300) and (45, 275)

Using the point-slope form of a line, we get:

(275 - 300) / (45 - 40) = -5/25 = -1/5

y - 300 = (-1/5)(x - 40)

y = (-1/5)x + 320

where y is the number of units sold per week and x is the price per unit.

The revenue function is simply the product of the price and the number of units sold:

R = xy

Substituting the demand function, we get:

R = x(-1/5)x + 320x

Simplifying, we get:

R = -1/5x^2 + 320x

To find the price per unit that yields maximum revenue, we need to take the derivative of the revenue function with respect to x and set it equal to zero:

dR/dx = -2/5x + 320 = 0

Solving for x, we get:

x = 800/2 = $400

The y-intercept of the graph is located at (0, 0). So, the value of c is 0.

What is graph?

A graph is a visual representation of data that displays the relationship between two or more variables. It consists of a set of points, called vertices or nodes, which are connected by lines or curves, called edges or arcs. The vertices represent the variables, while the edges represent the relationship between them.

To find the y-intercept of the graph of y = -7x + 140y, we need to substitute x = 0 into the equation and solve for y. This will give us the y-coordinate of the point where the graph intersects the y-axis.

Substituting x = 0, we get:

y = -7(0) + 140y

y = 140y

Simplifying the equation, we get:

139y = 0

Dividing both sides by 139, we get:

y = 0

Therefore, the y-intercept of the graph is located at (0, 0). So, the value of c is 0.

In geometry, a coordinate system is a method that uses one or more numbers or coordinates to determine the precise arrangement of points or other geometrical objects on a manifold, such as Euclidean space. Coordinates are pairs of numbers that are used to locate a point or object on a two-dimensional plane. A point's location on a 2D plane is represented by two numbers known as the x and y coordinates. a set of digits that represent precise locations. Typically, the figure has two numbers. The first number represents the front-to-back distance, while the second number represents the top-to-bottom distance. As in (12.5), when there are 12 units below and 5 above.  

To conduct a dilation with a scale factor of 1/2 around the origin, multiply each point's coordinates by 1/2. If the initial coordinates of point A are (x,y), then the dilated point A' coordinates are:

A' = (1/2 * x, 1/2 * y)

The area of one slice of a large pizza with a diameter of 24 inches is 56.52 square inches.

The formula for calculating the area of a circle is A = πr^2, where A is the area of the circle, π is the constant pi (3.1415) and r is the radius of the circle. To calculate the area of a slice, we must first calculate the radius of the pizza. To do this, we divide the diameter of the pizza (24 inches) by 2, which yields a radius of 12 inches.

Now that we have the radius, we can calculate the area of one slice. Plugging the radius of 12 inches into the equation, we get A = 3.1415*12^2 = 452.16 square inches. Since each pizza is cut into 8 equal slices, each slice would have an area of 452.16/8 = 56.52 square inches.

To calculate a rate, divide two quantities with different units; to calculate a unit rate, divide a rate by the quantity being measured.

What is rate ?

In mathematics, a rate is a ratio that compares two quantities with different units. It is typically expressed as the amount of change of one quantity with respect to another quantity. Rates are often used in the context of describing how quickly or slowly something changes over time or space.

To calculate a rate, we need to divide two quantities that have different units. For example, if we want to find the rate of a car's speed, we divide the distance traveled (in miles) by the time taken to travel that distance (in hours).

The formula for rate is:

rate = quantity / time

To calculate a unit rate, we need to divide a rate by the quantity being measured. For example, if the rate is the number of miles traveled per hour, the unit rate would be the number of miles traveled in one hour. To find the unit rate, we divide the rate by 1 hour.

The formula for unit rate is:

unit rate = rate / 1

When calculating rates or unit rates, it is important to make sure that the units of the quantities being divided are consistent. If the units are not the same, we need to convert them to the same unit before performing the division.

Therefore, to calculate a rate, divide two quantities with different units; to calculate a unit rate, divide a rate by the quantity being measured.
