Therefore, the relationship of the fluxions using Newton's rules for the equation y²-a²-x is given as: dy/dx = 2y = 2/2a = 1/a.
Newton's law of fluxions is a set of statements that describe how to compute the derivative of a function using the limit of difference quotients, the derivative being referred to as a "fluxion."
To find the relationship of the fluxions using Newton's rules for the equation y²-a²-x, we have to first find the derivative of the given equation. The derivative of the given function is given as follows:
dy/dx = -1
Differentiating with respect to x gives:
dy/dx (y²-a²-x) = dy/dx(y²) - dy/dx(a²) - dy/dx(x) = 2y(dy/dx) - 0 - 1
Now, since the slope is zero at x = a, we have dy/dx = 0
when x = a, the equation becomes dy/dx(y²-a²-a) = 2ay - 1= 0
Hence, we can solve for y at x = a by rearranging the equation as follows:
2ay = 1y = 1/2a
Therefore, the relationship of the fluxions using Newton's rules for the equation y²-a²-x is given as:
dy/dx = 2y = 2/2a = 1/a.

Step-by-step explanation:
Find the equation of a line that has the same slope as y = 5 - 9x and the same y-intercept as y=-8x - 10.
Answer:
y=-9x-10
Step-by-step explanation:
First, start by putting the first equation into slope intercept form:
y=-9x+5
We know that in the standard slope intercept formula (y=mx+b), m is the slope and b is the y intercept. Thus, line with the same slope as the one above would have a slope of -9.
To have the same y intercept as y=-8x-10, the y intercept would have to be -10.
Therefore, the formula would be y=-9x-10
Answer:
y = - 6/5x + 8/9
Step-by-step explanation:
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Consider these three numbers expressed in scientific notation: 8. 2 × 10-3, 5. 2 × 10-6, and 4. 1 × 10-6. Which number is the greatest, and by how many times is it greater than the smallest number? A. The greatest number is 8. 2 × 10-3. It is 20 times greater than the smallest number. B. The greatest number is 5. 2 × 10-6. It is 20 times greater than the smallest number. C. The greatest number is 8. 2 × 10-3. It is 2,000 times greater than the smallest number. D. The greatest number is 5. 2 × 10-6. It is 2,000 times greater than the smallest number.
You can convert from scientific notation to simple notation using the fact that negative powers can be converted to division.
The correct option is given by
Option C. The greatest number is 8. 2 × 10-3. It is 2,000 times greater than the smallest number.
How does negative power work?Suppose you have got \(a^{-b}\)
Then we have
\(a^{-b} = \dfrac{1}{a^b}\)
Converting from scientific notation to normal decimal notation\(8.2 \times 10^{-3} = \dfrac{8.2}{10^3} = \dfrac{8.2}{1000} = 0.0082\\\\5.2 \times 10^{-6} = \dfrac{5.2}{10^6} = \dfrac{5.2}{1000000} = 0.0000052\\\\4.1 \times 10^{-6} = \dfrac{4.1}{10^6} = \dfrac{4.1}{1000000} = 0.0000041\)
Thus, we can see that
The greatest number among given numbers is \(8.2 \times 10^{-3}\)
The smallest number among the given numbers is \(4.1 \times 10^{-6}\)
Dividing greatest number by smallest to see how many times the greatest number is greater than the smallest number
\(\dfrac{8.2 \times 10^{-3}}{4.1 \times 10^{-6}} =\dfrac{8.2}{4.1} \times \dfrac{10^{-3}}{10^{-6}} = 2 \times 10^{-3 - (-6)} = 2 \times 10^3 = 2000\)
Remember that when base are same, and there is division, then power gets subtracted, that's why we got \(\dfrac{10^{-3}}{10^{-6}} = 10^{-3 - (-6)} = 10^3\)
Thus, we have the greatest number 2000 times bigger than the smallest number among the numbers given.
Thus, the correct option is
Option C. The greatest number is 8. 2 × \(10^{-3}\). It is 2,000 times greater than the smallest number.

The distribution of SAT scores for college bound male seniors has a mean of 1512 and a standard deviation of
322. The distribution of SAT scores for college bound female seniors has a mean of 1486 and a standard deviation of
311. What is the probability that a randomly selected female senior will have a lower score than a male senior?
The probability that a randomly selected female senior will have a lower score than a male senior with a score of 1512 is approximately 0.788, or 78.8%.
What is the probability?
Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1. An event with a probability of 0 cannot occur, while an event with a probability of 1 is certain to occur.
To find the probability that a randomly selected female senior will have a lower score than a male senior, we need to use the standard normal distribution table, which gives the probability that a randomly selected value from a normal distribution with a mean of 0 and a standard deviation of 1 will be less than a certain value.
We can use the z-score formula to standardize the female senior's SAT score, which is given by:
z = (x - mean) / standard deviation
Where x is the female senior's SAT score, mean is the mean of the distribution of SAT scores for college bound female seniors, and standard deviation is the standard deviation of the distribution of SAT scores for college bound female seniors.
So the z-score for a female senior with a score of 1512 (the same as the mean of the male seniors) is:
z = (1512 - 1486) / 311 = 0.8
Looking at the standard normal distribution table, we can see that the probability that a value from a standard normal distribution is less than 0.8 is approximately 0.788.
Hence, the probability that a randomly selected female senior will have a lower score than a male senior with a score of 1512 is approximately 0.788, or 78.8%

solve the logarithmic equation 2log4-log3+2logx-4=0.
The logarithmic equation 2log4 - log3 + 2logx - 4 = 0 can be solved by rewriting the equation using logarithmic properties and then solving for x. The exact value of x depends on the logarithmic base used.
To solve the logarithmic equation 2log4 - log3 + 2logx - 4 = 0, we can start by applying logarithmic properties. Using the properties
log(a) - log(b) = log(a/b) and log(a^b) = b log(a), we can rewrite the equation as log(4^2) - log(3) + log(x^2) - log(10,000) = 0.
Simplifying further, we have 2 log(16) - log(3) + 2 log(x) - 4 = 0.
Next, we can combine the logarithmic terms using the property
log(a) + log(b) = log(a * b). This gives us log(16^2 * x^2 / 3) - 4 = 0. Simplifying the logarithm, we have log(256x^2/3) - 4 = 0.
To isolate the logarithm, we can apply the property a = b implies 10^a = 10^b. In this case,
10^(log(256x^2/3) - 4) = 10^0. This simplifies to 256x^2/3 = 10^4.
Finally, we solve for x by rearranging the equation. Multiplying both sides by 3/256, we get x^2 = (3/256) * 10^4. Taking the square root of both sides, we have x = ±√(3/256) * 10^2. Thus, the exact value of x depends on the logarithmic base used, but this provides the general form of the solution.

The expression to represent the p pages David has read is: p = 18 + (1/4)x, where x is the total number of pages in the book.
David has read 18 pages more than 1/4 pages of a book. The expression to represent the p pages that David has read would be: p = 18 + (1/4)x, where x is the total number of pages in the book. The reasoning behind this is as follows:
David has already read 18 pages more than 1/4 of the book, so we have to add 18 pages to whatever the pages of the book are. Since we don't know what the actual number of pages are, we'll call that x. Therefore, David read 1/4 of the book (or 1/4 of x) plus 18 pages.
Hence, the expression is: p = 18 + (1/4)x.

which of the following is one of the requirements for using a one-way, between-subjects anova?
The following is one of the requirements for using a one-way, between-subjects Anova is the data must be measured on a continuous scale.
Between-subjects ANOVAOne of the requirements for using a one-way, between-subjects ANOVA is that the data must be measured on a continuous scale. This means that the variable being measured (such as time, weight, or temperature) should be able to take on any value within a certain range.
Another requirement for using a one-way, between-subjects ANOVA is that the data must be independent. This means that the observations for each group should not be related to one another in any way. For example, if the groups being compared are different treatment groups in a medical study, it would not be appropriate to use a one-way, between-subjects ANOVA if the patients in each group were related to one another (such as siblings or close friends).
The third requirement is that the data should be approximately normally distributed in each group. A normal distribution is a probability distribution that has a bell shape, which means that the data is symmetric and the mean, median, and mode are equal. The ANOVA assumes that the data is normally distributed and if the data is not normally distributed, the results may be unreliable. This requirement can be checked by using normality test such as Shapiro-Wilk test.

A 10' tall wall is to be poured using 150 PCF concrete at a rate of 7 feet per hour with an expected temperature of 50 degrees. what is the expected vertical load on the foundation? a) 1050 PSF b) 1500 PSF c) 150 PSF d) 1200 PSF
The expected vertical load on the foundation is option b) 1500 PSF (pounds per square foot)
To calculate the expected vertical load on the foundation, we need to consider the weight of the concrete and the height of the wall.
The weight of the concrete can be determined using the unit weight of concrete, which is given as 150 pounds per cubic foot (PCF). Since the wall is 10 feet tall, we can calculate the weight of the concrete per square foot of the wall.
Weight of concrete per square foot = unit weight of concrete * height of the wall
Weight of concrete per square foot = 150 PCF * 10 feet = 1500 pounds per square foot (PSF)
Therefore, the expected vertical load on the foundation is 1500 PSF (option b).
This means that for every square foot of the foundation, it is expected to bear a load of 1500 pounds due to the weight of the poured concrete.
It is important to note that factors such as soil conditions, additional loads, and structural considerations may influence the actual load on the foundation. It is recommended to consult with a structural engineer for precise calculations and design requirements.

Patrick received a total of approximately $6,785.97 over the course of 52 weeks.
To calculate the total amount of money Patrick received over the 52 weeks, we can use the concept of a geometric sequence. The first term of the sequence is $10, and each subsequent term is 10% more than the previous term.
To find the sum of a geometric sequence, we can use the formula:
Sn = a * (r^n - 1) / (r - 1),
where Sn is the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms.
In this case, a = $10, r = 1 + 10% = 1.1 (common ratio), and n = 52 (number of weeks).
Plugging these values into the formula, we can calculate the sum of the sequence:
S52 = 10 * (1.1^52 - 1) / (1.1 - 1)
After evaluating this expression, we find that Patrick received approximately $6,785.97 over the 52 weeks.
As a result, Patrick collected about $6,785.97 in total over the course of 52 weeks.
