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.

The normal curve can be used to approximate the binomial probability as all conditions are met, with at least 10 successes and failures, a success rate of less than 10%, and a sample size of at least 20.

Only when specific requirements are met can the normal curve be used to approximate the binomial probability in this situation. The trial must have at least 10 successes and 10 failures as its initial requirement. There are more than 10 successes and 10 failures in this instance since 124 machines are being tested. The second requirement is that the likelihood of success must be under 10%. The likelihood of a computer failing in this scenario is 4%, which is less than 10%.

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

When we scale up by a factor of 5, we get:

D'E' + E'F' + F'D' = 5DE + 5EF + 5FD

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.

we can deduct that the angle on the L vertex is 25°, because that way all three angles will result in 180°.

We know that JKLM is a parallelogram, which means that its opposite sides are parallels, such that: JK // ML and JM // KL.

So, we know that the angle MLJ equals 25°, and JK // ML, from this we can say that angles LJK and MLJ are equal, because they are ''internal alternate angles'', since that they are inside the parallels.

So, angle LJK is 25, and JKL is a triangle, which has the angle at K vertex equal to 130°. We know that internal angles in a triangle must sum 180°.

Since that, two angles, in the triangle JKL, measure 130° + 25° = 155°; we can deduct that the angle on the L vertex is 25°, because that way all three angles will result in 180°.

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:

For Milton to fill the 3-gallon aquarium with water, the 1-quart container will need to be filled and emptied 12 times.

The 3-gallon aquarium must first be converted to quarts. A 3-gallon aquarium holds 12 quarts since 1 gallon equals 4 quarts.

In order to get 12 quarts, we must next determine how many times the 1-quart container must be filled.

12 quarts divided by one quart equals 12 containers.

(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.

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)

We negate the x-coordinate while keeping the y-coordinate constant to represent the dilated point A' over the y-axis. As a result, the final coordinates of A" are:

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

A translation transformation rule describes how to move an object in the plane without changing its shape, size, or orientation. A reflection transformation rule describes how to flip an object across a line or plane. A scaling transformation rule describes how to change the size of an object by multiplying its coordinates by a scalar factor. A rotation transformation rule describes how to rotate an object around a fixed point by a certain angle.

From the graph, we can see,

The coordinates of the figure A are (-2, 0), (-2, 3) and (-5, 2)

The coordinates of the figure A' are (2, 0), (2, 3) and (5, 2)

The reflection across the y-axis, according to the rule is: [tex](x, y)[/tex] → [tex](-x, y)[/tex]
