Answer:

-1/10, 2/10, and 4/10

Step-by-step explanation:

A rational number is a number that is in the form of p/q, where p and q are integers, and q is not equal to 0.

First, what is the lcm of 5 and 2? the lcm is 10, because that is the lowest number than can be divided separately by 5 and 2 and the results would still be a whole number.

We now need to find 3 rational numbers between -2/10 and 5/10. It's easy now that I've explained it, right?

-1/10, 2/10, and 4/10 are between -1/5 and 1/2 and are integers with the given explanation.

Therefore, the decimal number 0.00086 written in scientific notation is 8.6 × 10-4 and it has 2 significant figures.

In inferential statistics, we calculate statistics of sample data to estimate the characteristics of the entire population from which the sample was taken. The process involves drawing inferences about a population from a random sample of data taken from that population.

The sample statistics are used to estimate the parameters of the population. To make an inference, we use a hypothesis test or confidence interval based on the sample statistics. The key to inferential statistics is random sampling, which allows us to make generalizations about the population based on the characteristics of the sample.

In order to ensure that the sample is representative of the population, we use a variety of sampling techniques, including simple random sampling, stratified sampling, cluster sampling, and systematic sampling.

Each of these techniques has its own advantages and disadvantages, and the choice of technique depends on the characteristics of the population being studied and the research questions being asked.

Once we have a representative sample, we use statistical methods to draw conclusions about the population. This allows us to make predictions and to test hypotheses about the population with a high degree of confidence.

Answer:

A because a prism is the only solid they can be used in that way

the computer component will cost approximately $72.90 in three years.

The decrease in the price of the computer component at a rate of 10% per year indicates an exponential decrease. This is because a constant percentage decrease over time leads to exponential decay.

To calculate the cost of the component in three years, we can use the formula for exponential decay:

\[P(t) = P_0 \times (1 - r)^t\]

Where:

- \(P(t)\) is the price of the component after \(t\) years

- \(P_0\) is the initial price of the component

- \(r\) is the rate of decrease per year as a decimal

- \(t\) is the number of years

Given that the component costs $100 today (\(P_0 = 100\)) and the rate of decrease is 10% per year (\(r = 0.10\)), we can substitute these values into the formula to find the cost of the component in three years (\(t = 3\)):

\[P(3) = 100 \times (1 - 0.10)^3\]

\[P(3) = 100 \times (0.90)^3\]

\[P(3) = 100 \times 0.729\]

\[P(3) = 72.90\]

Answer: y = 7x + 5 (maybe, please make sure, I'm very doubtful of myself sometimes)

Step-by-step explanation:

1. With the given numbers, m is slope, so 7 is the slope and b is y-intercept, and 5 is the y-int in this case.

2. This is hinting that the equation is in slope intercept form, which is      y = mx + b.

3. Since y = mx + b is the formula, then it means y = 7x + 5 is the likely answer

The pigeonhole principle states that if there are more pigeons than pigeonholes, then at least one pigeonhole must contain more than one pigeon. We can apply this principle to prove the following statements:

(a) Given any seven integers, there will be two that have a difference divisible by 6.

We can divide the integers into six pigeonholes based on their remainders when divided by 6: {0}, {1}, {2}, {3}, {4}, and {5}. Since there are seven integers, by the pigeonhole principle, at least two integers must belong to the same pigeonhole. If two integers belong to the same pigeonhole, then their difference will be divisible by 6.

(b) Given any five integers, there will be two that have a sum or difference divisible by 7.

We can divide the integers into six pigeonholes based on their remainders when divided by 7: {0}, {1}, {2}, {3}, {4}, {5}, and {6}. Since there are five integers, by the pigeonhole principle, at least two integers must belong to the same pigeonhole. If two integers belong to the same pigeonhole, then their sum or difference will be divisible by 7.

Note that if the two integers have the same remainder when divided by 7, then their difference will be divisible by 7. If they have different remainders, then their sum will be divisible by 7.

Here is the program that draws a pyramid of circles based on user input. The user is asked to input the number of rows for the pyramid. Each row has an increasing number of circles as you go down the pyramid.```# Importing turtle module import turtle# Function to draw circledef draw_circle(radius):    turtle.circle(radius)

# Function to move turtle to specified coordinatesdef move_turtle(x, y):    turtle.penup()    turtle.goto(x, y)    turtle.pendown()# Main function def main():    # User input for number of rows in pyramid    rows = int(input("Enter the number of rows for the pyramid: "))    x = -50    y = 0    radius = 10    distance = 30    for i in range(rows):        for j in range(i+1):  draw_circle(radius)            move_turtle(x, y)            x += distance        x = -50        y -= distance    turtle.done()# Calling main function if __name__ == '__main__':    main()```

The program starts by importing the turtle module, which is used to draw the circles. The program then defines two functions: `draw_circle()` and `move_turtle()`. The `draw_circle()` function takes a radius as an argument and uses the turtle module to draw a circle with that radius.

................................................i dont know

The largest value that f(4) can possibly be is 29.

The mean value theorem states that for a function f(x) that is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), there exists a number c in the open interval (a, b) such that:

f(b) - f(a) = f'(c)(b - a)

In this case, we are given that f(0) = -3 and that f'(x) ≤ 8 for all values of x. To determine how large f(4) can possibly be, we can use the mean value theorem with a = 0 and b = 4:

f(4) - f(0) = f'(c)(4 - 0)

Substituting the given values:

f(4) - (-3) = f'(c)(4)

f(4) + 3 = 4f'(c)

Since f'(x) ≤ 8 for all values of x, we can say that f'(c) ≤ 8. Therefore:

f(4) + 3 ≤ 4f'(c) ≤ 4(8) = 32

Therefore, we have:

f(4) ≤ 32 - 3 = 29

The correct answer to this question is A. 9.4 x \(10^{-8}\), 9.25 x \(10^{-6}\), 2.5 x \(10^{3}\), 7 x

Explanation:

These numbers are written in scientific notation. In this system, the exponent shows the number of spaces the period has been moved to make the number shorter. Additionally, a positive exponent shows the number has a certain number of digits to the right, while a negative exponent shows the number has digits to the left. In this way, the numbers presented can be converted as:

9.4 x \(10^{-8}\) = 0.000000094 (Exponent indicates eight spaces to the left)

9.25 x \(10^{-6}\) = 0.00000925 (Exponent indicates six spaces to the left)

2.5 x \(10^{3}\) = 2500 (Exponent indicates three spaces to the right)

7 x \(10^{3}\) =  7000 (Exponent indicates three spaces to the right)

To determine the local behavior of the function f(x) = -4x(x^2)(x-4), we can examine the signs and multiplicity of the factors involved.

This will help us identify the intervals where the function is increasing or decreasing, as well as locate any local extrema (maximum or minimum points).

Let's analyze the factors of the function:

x:

The factor x appears once, so it changes signs at x = 0.

It is a linear factor, so it has a slope of 1 and passes through the origin.

(x^2):

The factor (x^2) appears with an even power, which means it is always non-negative.

It is a quadratic factor, so its graph is a parabola that opens upwards.

(x-4):

The factor (x-4) appears once, so it changes signs at x = 4.

It is a linear factor, so it has a slope of 1 and passes through the point (4, 0).

Now, let's consider the local behavior of the function:

At x = 0:

The factor x is zero, so f(0) = 0.

Since (x^2) and (x-4) are non-zero, their effect does not change the sign of the overall function.

Therefore, we have a potential local minimum at x = 0.

Between x = 0 and x = 4:

The factor x remains non-zero and positive in this interval.

The factor (x-4) changes signs from negative to positive.

The overall function f(x) will be negative in this interval.

At x = 4:

The factor (x-4) is zero, so f(4) = 0.

Since x and (x^2) are non-zero, their effect does not change the sign of the overall function.

Therefore, we have a potential local maximum at x = 4.

For x > 4:

The factor (x-4) remains non-zero and positive in this interval.

The factor x changes signs from positive to negative.

The overall function f(x) will be positive in this interval.

Based on this analysis, we can summarize the local behavior of the function f(x) = -4x(x^2)(x-4) as follows:

There is a potential local minimum at x = 0.

There is a potential local maximum at x = 4.

The function is negative between x = 0 and x = 4.

The function is positive for x > 4.

Please note that these conclusions are based on the factors and their signs, and additional analysis might be necessary to confirm the nature of the local extrema.

The total number of positive integers with exactly three proper divisors and each divisor less than 50 is \(7+18=\boxed{25}$.\)

To have exactly three proper divisors, a number must be of the form \(p_1^2$ or $p_1p_2$\), where \($p_1$\) and \($p_2$\) are prime numbers.

For the case of \(p_1^2$,\) there are only 7 prime numbers less than 50. So, there are 7 possible numbers of the form \(p_1^2$.\)

For the case of \($p_1p_2$\), we can choose 2 prime numbers from the 7 available prime numbers, which can be done in \($\binom{7}{2} = 21$\) ways. However, we must exclude the numbers that are squares of primes, which are already counted in the previous case. There are 3 such numbers: \(2^2$, $3^2$,\)and $5^2$. So, there are \($21-3=18$\) possible numbers of the form \(p_1p_2$.\)

The diffusion time of the red blood cell to take oxygen through the membrane is 25uS.

The small capillaries in the lungs are in close contact and it takes a red blood cell 0.5 seconds to squeeze through the capillary.

The diffusion time for the oxygen across the 1 um thick membrane separating the air is given by,

t = x²/2D

Where,

t is the diffusion time,

x is the thickness of the membrane,

D is the diffusion coefficient.

Putting values,

t = (1 x 10⁻⁹)²/2 x 2 x 10⁻¹¹

t = 10⁻⁷/4

t = 25 x 10⁻⁹ seconds.

t = 25 uS.
