Answers

Answer 1
The coordinates of the center of this circle will be the average between the extreme points


C = ( (xo+x1)/2 , (yo+y1)/2)

Where,

xo = 3 and x1 = 9

yo = 8 and y1 = 16

Then us stay with"


C = ( (3+9)/2 , (8+16)/2)

Answer: y = 4/5 - 6.2

y = mx + b

first get the 2 points and plug it in to the equation

y - y1 = m (x -x1)

y - 3 = 4/5 (x - 4)

y - 3 = 4/5x - 3.2

add 3 on both sides

Find the curvature and the radius of curvature at the point t=0. x=e
t
cos(t),y=e
t
sin(t),z=11e
t
κ=

Answers

The magnitude of the cross product is imaginary, the curvature at t = 0 is undefined, and therefore, the radius of curvature is also undefined.

To find the curvature κ at the point where t = 0, we need to calculate the first derivative, second derivative, and the magnitude of the cross product of the first and second derivatives.

Given:

x = e^t * cos(t)

y = e^t * sin(t)

z = 11e^t

First, let's find the derivatives:

dx/dt = -e^t * sin(t) + e^t * cos(t)

dy/dt = e^t * cos(t) + e^t * sin(t)

dz/dt = 11e^t

Now, let's find the second derivatives:

d^2x/dt^2 = -e^t * cos(t) - e^t * sin(t) - e^t * sin(t) - e^t * cos(t)

         = -2e^t * sin(t) - 2e^t * cos(t)

d^2y/dt^2 = -e^t * sin(t) + e^t * cos(t) + e^t * cos(t) + e^t * sin(t)

         = 2e^t * cos(t)

d^2z/dt^2 = 11e^t

Now, we can calculate the cross product of the first and second derivatives:

r' = [dx/dt, dy/dt, dz/dt]

r'' = [d^2x/dt^2, d^2y/dt^2, d^2z/dt^2]

cross product = r' x r'' = [dy/dt * d^2z/dt^2 - dz/dt * d^2y/dt^2, dz/dt * d^2x/dt^2 - dx/dt * d^2z/dt^2, dx/dt * d^2y/dt^2 - dy/dt * d^2x/dt^2]

Substituting the values, we get:

cross product = \([(e^t * cos(t))(11e^t) - (11e^t)(2e^t * cos(t)), (11e^t)(-2e^t * sin(t)) - (-e^t * sin(t))(11e^t), (-e^t * sin(t))(2e^t * cos(t)) - (e^t * cos(t))(2e^t * sin(t))]\)

Simplifying further:

cross product =\([11e^{(2t)} * cos(t) - 22e^{(2t)} * cos(t), -22e^{(2t)} * sin(t) + 11e^{(2t)} * sin(t), -2e^{(2t)} * sin(t) * cos(t) + 2e^{(2t)} * sin(t) * cos(t)]\)

cross product = \([11e^{(2t)} * cos(t) - 22e^{(2t)} * cos(t), -11e^{(2t)} * sin(t), 0]\)

Now, we can find the magnitude of the cross product:

|cross product| \(= \sqrt{((11e^{(2t)} * cos(t) - 22e^{(2t)} * cos(t))^2 + (-11e^{(2t)} * sin(t))^2 + 0^2)\)

               \(= \sqrt{((121e^{(4t)} * cos^2(t) - 484e^{(4t)} * cos^2(t) + 242e^{(4t)} * cos(t) * sin(t) + 121e^{(4t)} * sin^2(t)))\)

At t = 0

:

|cross product| = \(\sqrt{((121 * 1 - 484 * 1 + 242 * 0 + 121 * 0))}\)

                         =  \(\sqrt{(-242)}\)

Since the magnitude of the cross product is imaginary, the curvature at

t = 0 is undefined, and therefore, the radius of curvature is also undefined.

The standard error of the mean for a sample of 100 is 30. In order to cut the standard error of the mean to 15, we would a) increase the sample size to 200. b) increase the sample size to 400. c) decrease the sample size to 50. d) decrease the sample to 25.

Answers

In the event of shortening the standard error of mean to 15 we have to increase the size to 400. Therefore, the correct answer is Option B.


The  given standard error of the mean for a sample of 100 is 30. So to cut the standard error of the mean to 15, we have to proceed by increasing the sample size to 400.


The  formula for evaluating the standard error of mean
SEM = SD / √(n)
here, SEM = standard error of the mean,
SD = standard deviation
n = sample size
Staging the values
15 = SD / √(100)
15 x √(100) = SD
SD = 150
Now evaluating for the value of n
15 = 150 / √(n)
15 x √(n) = 150
√(n) = 10
n = 100
Now looking at the formula, we need to decrease SEM by half,


So we proceed by increasing the  sample size by a factor of 4.


In the event of shortening the standard error of mean to 15 we have to increase the size to 400. Therefore, the correct answer is Option B.

The mass of the sun is about ten million times greater than the mass of the moon. What is the approximate mass of the sun? Write in exponential form. The mass of the moon is 7.342 × 10²² kg (kilograms), and the mass of the sun is approximately 10 million times greater.

Therefore, the mass of the sun is approximately 10 million times the mass of the moon. Mass of the sun in exponential form can be expressed as: M = 10,000,000 × 7.342 × 10²² kg= 7.342 × 10²² × 10⁷ kg= 7.342 × 10²⁹ kg

Answers

The throw of the dice or the drawing of a card is known as random behavior.

Random behavior refers to events that occur by chance, without any predictability or pattern. These events cannot be influenced or controlled, and their outcomes are determined by the laws of probability. In games such as dice and card games, the outcomes are determined by random variables, such as the position of the dice or the shuffle of the deck.

Random behavior can also occur in other contexts, such as weather patterns or the stock market, where events are subject to unpredictable fluctuations. Understanding random behavior is important in many fields, including mathematics, statistics, and economics, as it can help us make informed decisions based on the probability of different outcomes.

An estuary is where a river pours into the ocean. So that means fresh water mixes with salt water here. This allows us to rule out choices A and B.

According to NOAA, their site says "Estuaries are one of the most productive ecosystems in the world, so there is a great diversity of animals and plants that live there". In other words, a lot of plants and animals live here, so we can rule out choice C.

Choice D is the answer because tides do affect estuaries. This is simply because the ocean is pretty much right next to it, or attached to it. So it's expected that a high tide would cause the water level in an estuary to increase.

How do you find the volume of cubes and rectangular prisms?

Answers

To find the volume of a cube or rectangular prism, multiply the length, width, and height of the shape. The formula is V = l × w × h, where V represents volume, l represents length, w represents width, and h represents height.

Cubes and rectangular prisms are both three-dimensional shapes, which means they have volume. Volume is the amount of space an object occupies. To find the volume of a cube or rectangular prism, you need to know its dimensions. The dimensions of a cube or rectangular prism are its length, width, and height.
Volume of a Cube
A cube is a three-dimensional shape that has six equal square faces. To find the volume of a cube, you need to know the length of one of its sides. The formula for finding the volume of a cube is:
Volume = side x side x side
Or
V = s³
Where V is the volume and s is the length of one of its sides.
Volume of a Rectangular Prism
A rectangular prism is a three-dimensional shape that has six faces. The faces of a rectangular prism are rectangles. To find the volume of a rectangular prism, you need to know the length, width, and height of the shape. The formula for finding the volume of a rectangular prism is:
Volume = length x width x height
Or
V = lwh
Where V is the volume, l is the length, w is the width, and h is the height of the rectangular prism.

Answers

The total cost before the sales tax was 19.828 pounds.

For a party, Jordan purchased 3.8 pounds of turkey, 2.2 pounds of cheese, and 3.6 pounds of egg salad.

We have to determine the total cost before sales tax.

As per the question, we have prices as:

cost of turkey = 3.95 per pound

cost of egg cheese = 1.3 per pound

cost of egg salad = 0.89 per pound

The total cost of turkey = 3.8 × 3.95  = 15.01 pounds

The total cost of cheese = 2.2 × 1.3 = 2.86 pounds

The total cost of egg salad = 2.2 × 0.89 = 1.958 pounds

The total cost before sales tax = 15.01 + 1.958 +2.86

4) the volumes of soda in quart soda bottles are normally distributed with a mean of 32.3 oz and a standard deviation of 1.2 oz. what percentage of bottles contain less than 32 oz of soda?

Answers

40.13  percentage of the bottles contain less than 32 oz of soda.

Mean (μ) = 32.3 oz

Standard Deviation (σ) = 1.2 oz

Threshold value (X) = 32 oz

We can use the standard normal distribution (Z-distribution) to calculate the cumulative probability.

First, let's standardize the threshold value using the formula

Z = (X - μ) / σ

Z = (32 - 32.3) / 1.2 Z ≈ -0.25

Next, we'll look up the cumulative probability corresponding to Z = -0.25 in the standard normal distribution table or use a calculator.

From the standard normal distribution table or calculator, we find that the cumulative probability for

Z = -0.25 is approximately 0.4013.

This means that approximately 40.13% of bottles contain less than 32 oz of soda.

Therefore, about 40.13% of the bottles contain less than 32 oz of soda.
