Let's first write out the proportionality statement based on the information given:

distance ∝ time^2

We can then write an equation for the relationship between the distance and time:

distance = k(time^2)

where k is the constant of proportionality. We need to solve for k in order to use this equation to answer the question.

We know that when the egg falls for ½ second, it falls 8 feet. Plugging in these values, we get:

8 = k(0.5^2)

8 = 0.25k

k = 32

Now that we have k, we can use the equation to find the time it takes the egg to fall 200 feet. We rearrange the equation to solve for time:

distance = k(time^2)

time^2 = distance/k

time = sqrt(distance/k)

Plugging in the values, we get:

time = sqrt(200/32) = 2.5 seconds

Therefore, it will take the egg 2.5 seconds to fall 200 feet.

a. The London population data cannot be accurately modeled by a linear function because the population growth is not constant over time. A quadratic function may be able to fit the data, but it is unlikely to accurately model the population growth in the long term. An exponential function is a more suitable choice because it can model exponential population growth, which is common in real-world scenarios.

b. Using a logistic growth equation, we can determine if the London population data can be accurately modeled by a logistic equation. We can use a regression analysis to find the values of a, b, and c that best fit the data, and then compare the predicted values to the actual population data to determine the accuracy of the model.

c. The logistic growth equation P(t) = 1 / (a + be^(-b(t-c))) produces an S-shaped curve, which represents the growth of a population that is initially slow, then accelerates, and finally levels off as it approaches a carrying capacity. The value of a represents the initial population size, b represents the growth rate, and c represents the time at which the population growth rate is highest. As a increases, the curve shifts upwards, indicating a larger initial population size. As b increases, the curve becomes steeper, indicating faster population growth. As c increases, the curve shifts to the right, indicating a later time at which the population growth rate is highest.

The total surface area of tumbler designed like cube with cylindrical hole is 700.48cm² and cost of glass to make tumbler is $3 (round off).

Shape of the tumbler is cube.

Side length of the edges = 10cm

Radius of the cylindrical hole = 4cm

Depth of the cylindrical hole = 8cm

Total surface area of the tumbler = surface area of the cube and the surface area of the cylinder - (surface area of the cylindrical hole ).

The surface area of a cube with edge length 10 cm is,

6 × (10 cm)² = 600 cm²

The surface area of a cylinder with radius 4 cm and height 8 cm is,

2π(4 cm)² + 2π(4 cm)(8 cm) = 96π cm²

Surface area of the cylindrical hole is the lateral area of a smaller cylinder with radius 4 cm and height 8 cm,

2π(4 cm)(8 cm) = 64π cm²

So the total surface area of the tumbler is,

= 600 cm² + 96π cm² - 64π cm²

= 600 cm² + 32π cm²

≈ 700.48 cm²

Total volume of the tumbler = volume of the cube - volume of the cylindrical hole.

The volume of a cube with edge length 10 cm is,

(10 cm)³ = 1000 cm³

The volume of the cylindrical hole is,

π(4 cm)²(8 cm) = 128π cm³

So the total volume of the tumbler is,

= 1000 cm³ - 128πcm³

≈ 598.08 cm³

The cost of the glass needed to make the tumbler

= cost of one cubic centimeter of glass × total volume of the tumbler.

Since one cubic centimeter of glass costs half a cent.

The cost of the glass needed to make the tumbler is,

= 0.5 cents/cm³ × 598.08 cm³

≈ 299.04cents

≈ $3

Therefore, total surface area of tumbler is 700.48cm² approximately and  cost of glass needed to make tumbler is approximately $3.

Answer:

To find the coordinates of the vertex of the graph of the function -3x^2+12, we can use the formula x = -b/2a to find the x-coordinate of the vertex, and then substitute it back into the function to find the y-coordinate.

In this case, the function is in the form f(x) = -3x^2+12, so we can see that a = -3 and b = 0.

Using the formula x = -b/2a, we get:

x = -0/(2*(-3)) = 0

So the x-coordinate of the vertex is 0.

To find the y-coordinate of the vertex, we can substitute x = 0 into the function:

f(0) = -3(0)^2+12 = 12

So the y-coordinate of the vertex is 12.

Therefore, the coordinates of the vertex of the graph of the function -3x^2+12 are (0, 12).

The limit of (x + x²)/(2 − 3x²) as x approaches infinity is -1/3.

To find the limit of (x + x²)/(2 − 3x²) as x approaches infinity, we can use l'Hospital's Rule.

First, we need to check if the limit is in the indeterminate form 0/0 or ∞/∞. As x approaches infinity, both the numerator (x + x²) and the denominator (2 - 3x²) approach infinity.

Therefore, the limit is in the indeterminate form ∞/∞, and we can apply l'Hospital's Rule.

l'Hospital's Rule states that if the limit is in the indeterminate form 0/0 or ∞/∞, we can take the derivative of the numerator and denominator separately, and then find the limit of the ratio of their derivatives.

Numerator's derivative: d/dx(x + x²) = 1 + 2x Denominator's derivative: d/dx(2 - 3x²) = -6x

Now, we'll find the limit of the ratio of their derivatives as x approaches infinity: lim (1 + 2x)/(-6x) as x→∞

We can use l'Hospital's Rule again, as this limit is also in the indeterminate form ∞/∞. Numerator's second derivative: d/dx(1 + 2x) = 2

Denominator's second derivative: d/dx(-6x) = -6

Now, we'll find the limit of the ratio of their second derivatives as x approaches infinity: lim (2)/(-6) as x→∞ Since the limit involves constants only, it does not depend on x, and we can directly compute the limit: 2 / (-6) = -1/3

Therefore, the limit of (x + x²)/(2 − 3x²) as x approaches infinity is -1/3.

The statement the area of bottom of round pan is greater than area of bottom of rectangular pan by about 8.5 square inches is correctly describes how the area of the bottom of the round pan compares to the area of the bottom of the rectangular pan.

What is a area of a surface?

In mathematics, the area of a surface refers to the measurement of the size of a two-dimensional region enclosed by a closed boundary or surface. It is typically expressed in square units such as square inches, square meters, or square feet. The concept of area is used in various fields such as geometry, physics, engineering, and many others to calculate the amount of material needed to cover a surface, to determine the capacity of a container, or to estimate the amount of paint required to paint a wall. The formula for calculating the area of a surface varies depending on the shape and complexity of the surface, but typically involves finding the product of two or more dimensions of the surface or using integration techniques in calculus to calculate the area under a curve.

To find the relation we have to find the areas of the pans.

Area of round pan nr 3.14 x 52 78.5 square = 78.5 inches.

Area of the rectangular pan = length x breadth = 10 x 7 = 70 square inches.

ans

If a relay lasts 5.92 miles and there are 4 runners on the team, we can divide the total distance by the number of runners to find the distance each person runs.

5.92 miles / 4 runners = 1.48 miles per runner

Therefore, each person on the relay team would run a distance of 1.48 miles, assuming that each runner runs in the same direction in the race.

It's important to note that in a relay race, each runner usually runs a specific distance that is predetermined by the race organizers. This distance may be different from the total distance of the race, and it may also be different for each runner on the team. However, if all runners on the team are running equal distances, as in this case, then we can simply divide the total distance by the number of runners to find the distance each person runs.

The correct answer is: a translation of 3 units down.

Step-by-step explanation:

To identify the transformation that occurred after the dilation, we can compare corresponding points on both parallelograms.

The point (-4,0) on parallelogram P was dilated to the point (3,0) on parallelogram P'. This means the x-coordinate was multiplied by 2, since 3 = -4 x 2.

Similarly, the point (-2,0) on parallelogram P was dilated to the point (7,0) on parallelogram P', indicating again that the x-coordinate was multiplied by 2 since 7 = -2 x 2.

Therefore, the dilation was a scale factor of 2 in the x-direction about point P.

To transform parallelogram P' from its position after the dilation to its final position, we can see that corresponding points have been translated 3 units down. For example, the point (3,0) was transformed to (3,-3), and the point (1,-6) was transformed to (-4,-6).

Thus, the transformation that occurred after the dilation was a translation of 3 units down.

The angle of rotation about O that maps IJ to RF is 120 degrees.

A hexagon is a polygon with six sides and six angles. It is a two-dimensional geometric shape that can be formed by connecting six straight line segments, where each segment intersects two others to form the six corners or vertices of the shape.

To find the angle of rotation about O that maps IJ to RF, we can follow these steps:

Note that IJ and RF are opposite sides of the regular hexagon, and since the hexagon is regular, they have the same length.

Since the hexagon is regular, we know that the angle between adjacent sides is 120 degrees.

Therefore, the angle between IJ and one of the dashed line segments must be 60 degrees (since it is the supplement of the 120 degree angle).

Let x be the angle of rotation about O that maps IJ to RF.

After the rotation, the angle between IJ and the dashed line segments will be x + 30 degrees (since the dashed line segments form 30 degree angles).

Similarly, the angle between RF and the dashed line segments will also be x + 30 degrees after the rotation.

Since IJ and RF are opposite sides of the regular hexagon, they form a 60 degree angle.

Therefore, we have the equation:

[tex]2(x + 30) + 60 = 360[/tex]

The left-hand side of the equation represents the sum of the angles around O after the rotation. The factor of 2 comes from the fact that each of the dashed line segments contributes to the angle twice.

Simplifying the equation, we get:

[tex]2x + 120 = 360[/tex]

[tex]2x = 240[/tex]

[tex]x = 120[/tex]

Therefore, the angle of rotation about O that maps IJ to RF is 120 degrees.

If the original price of the football is $22.00, and the store is offering a 20% discount, then the new price of the football before tax would be:

New price before tax = Original price - Discount

= $22.00 - (20% x $22.00)

= $17.60

Now, we need to calculate the price of the football after adding the sales tax of 5%. To do this, we can calculate the amount of sales tax first, and then add it to the new price before tax:

Sales tax = 5% x $17.60

= $0.88

Price after tax = New price before tax + Sales tax
