The function f(x)= 2x +4x^-1 has one local minimum and one local maximum.
This function has a local maximum at x=?
with value ?
and a local minimum at x=?
with value ?
The requried, local minimum and maxium for the given function is √2 and -√2.
We need to find the local maximum and local minimum of the function \(f(x) = 2x + 4x^{(-1)}.\)
First, we find the derivative of f(x):
\(f'(x) = 2 - 4x^{(-2)} = 2 - 4/x^2\)
Setting f'(x) = 0 to find the critical points:
\(2 - 4/x^2 = 0\)
Solving for x, we get:
x = ±√2
To determine whether these critical points are local maxima or minima, we need to examine the sign of the second derivative:
\(f''(x) = 8x^{(-3)}\)
When x = √2, f''(√2) = 8/(√2)³ = 8√2 > 0, so x = √2 is a local minimum.
When x = -√2, f''(-√2) = 8/(-√2)³ = -8√2 < 0, so x = -√2 is a local maximum.

Step-by-step explanation:
Review the proof of the identity cos(-A) = -COSA. at which step was an error made
The given identity is
\(\cos (\pi-A)=-\cos A\)Step 1 is about the trigonometric identify of angle difference which states
\(\cos (\pi-A)=\cos \pi\cdot\cos A+\sin \pi\cdot\sin A\)So, the first step is wrong since they used subtraction instead of addition.
Step 2 is about solving each trigonometric function of pi. We know that the cosine of pi is -1, and the sine of pi is 0. So, we have
\((-1)\cdot\cos A+0\cdot\sin A\)The second step is correct.
Steps 3 and 4 are about solving the products.
\((-1)\cdot\cos A+0\cdot\sin A=-\cos A+0\)Steps 3 and 4 are correct.
Step 5 is also correct since the zero doesn't change the cosine function.

Simplify the expression.
(4m²n² +6m²n)-(8m²n^ -7m²n²-13m²n)-(14m²n -2m^n² +9m²n)
Answer:
To simplify this expression, we need to combine like terms. To do that, we need to combine terms that have the same variables raised to the same powers.
First, we will combine the terms in the first set of parentheses:
(4m²n² + 6m²n)
We see that the terms have the same variables, m and n, and the same powers, 2 and 1, respectively. We can combine these terms by adding their coefficients:
(4m²n² + 6m²n) = (4 + 6)m²n = 10m²n
Next, we will combine the terms in the second set of parentheses:
(8m²n^ - 7m²n² - 13m²n)
In this case, we see that the first two terms have the same variables and powers, so we can combine them by adding their coefficients:
(8m²n^ - 7m²n² - 13m²n) = (8 - 7)m²n^ - 13m²n = m²n^ - 13m²n
We can then combine the remaining term with the first term in the expression:
m²n^ - 13m²n + 10m²n = m²n^ + (-13 + 10)m²n = m²n^ - 3m²n
Finally, we will combine the terms in the third set of parentheses:
(14m²n - 2m^n² + 9m²n)
In this case, we see that the first two terms have the same variable and power for the m variable, but the powers of the n variable are different. Since we cannot combine these terms, we will need to leave them as is. We can, however, combine the remaining term with one of the other terms:
(14m²n - 2m^n² + 9m²n) = 14m²n - 2m^n² + (9 + (-14))m²n = 14m²n - 2m^n² - 5m²n
We can then combine this expression with the previous one:
14m²n - 2m^n² - 5m²n + m²n^ - 3m²n = (14 - 1)m²n - 2m^n² - (5 - 3)m²n = 13m²n - 2m^n² - 2m²n
Finally, we have simplified the expression as much as possible:
(4m²n² + 6m²n) - (8m²n^ - 7m²n² - 13m²n) - (14m²n - 2m^n² + 9m²n) = 13m²n - 2m^n² - 2m²n

Using derivative of a function
f(x) = cosx and a = πWhat is the derivative of a function?The derivative of a function is its limit as the change in the independent variable tends to zero.
Now, since we have the \(\lim_{h \to 0}\frac{cos(\pi + h) - (- 1)}{h}\).
We know that the definition of the derivative of a function f(x) is
\(f'(x) =\lim_{h \to 0}\frac{f(x + h) - f(x)}{h}\)
Now, comparing both equations, we see that
f(x + h) = cos(x + h), f(x) = -1
Now, since f(x + h) = cos(x + h), we notice that f(x) must be a cosine function.
So, f(x) = cosx
Now, f(a) = -1
cosa = -1
a = cos⁻¹(-1)
= π
So, substituting this into the derivative equation, we have
\(f'(x) =\lim_{h \to 0}\frac{f(x + h) - f(x)}{h}\)
\(f'(x) =\lim_{h \to 0}\frac{cos(x + h) - (-1)}{h}\\=\lim_{h \to 0}\frac{cos(x + h) - cos(x)}{h}\\=\lim_{h \to 0}\frac{cos(\pi + h) - cos(\pi )}{h}\\= -sin\pi \\= 0\)

The machinery in a cereal plant fills 350 g boxes of cereal. The specifications for the machinery permit for a certain amount of fill tolerance. It is found that the weights of filled cereal boxes are normally distributed with a mean of 350 g and a standard deviation of 4 g. What is the probability that a box of cereal is under filled by 5 g or more?
There is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.
To find the probability that a box of cereal is underfilled by 5 g or more, we need to calculate the probability of obtaining a weight measurement below 345 g.
First, we can standardize the problem by using the z-score formula:
z = (x - μ) / σ
Where:
x = the weight value we want to find the probability for (345 g in this case)
μ = the mean weight (350 g)
σ = the standard deviation (4 g)
Substituting the values into the formula:
z = (345 - 350) / 4 = -1.25
Next, we can find the probability associated with this z-score using a standard normal distribution table or a statistical calculator.
The probability of obtaining a z-score less than -1.25 is approximately 0.1056.
However, we are interested in the probability of underfilling by 5 g or more, which means we need to find the complement of this probability.
The probability of underfilling by 5 g or more is 1 - 0.1056 = 0.8944, or approximately 89.44%.
Therefore, there is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.

If the area between the diagonal line of absolute equality and the Lorenz curve is greater for China than for United States, we can conclude that theA) distribution of income in China is closer to being equal than in the United States
B) distribution of the income in China is as equal as in United States
C) distribution of income in China is less equal than in the US*
D)relative distributions of income in the two countries are the same
If the area between the diagonal line of absolute equality and the Lorenz curve is greater for China than for United States, we can say that a) Distribution of income in China is less equal than in the United states.
Lorenz Curve:
In economics, the Lorentz curve is a graphical representation of the distribution of income or wealth. Developed by Max O. Lorenz in 1905 to show inequality in the distribution of wealth.
This curve plots the percentage of total income or wealth received by the bottom x% of the population, which is not always true for a finite population. Often used to describe income distribution, it shows what percentage (y%) of total income the bottom x% of households have. The X-axis shows household percentage and the Y-axis shows income percentage. It can also be used to represent the distribution of wealth. Used in this way, many economists see it as a measure of social inequality.
Distribution of Income:
Income distribution shows how a country's total GDP is distributed among its population. Economic theory and policy have long made income and its distribution a central concern. Unequal distribution of income causes economic inequality, which is a concern in almost every country in the world.
Classical economists such as Adam Smith (1723-1790), Thomas Malthus (1766-1834), and David Ricardo (1772-1823) focused on the distribution of factor income, i.e. production (land, labor, capital). . Modern economists have also addressed the issue of income distribution, but have focused more on the distribution of income between individuals and households. An important theoretical and policy concern is the balance between income inequality and economic growth, and their often inverse relationship.

Ms. Keenan is a high school teacher who wants to know how much time students spend studying each day. She finds that the average student spends 3.00 hours a day studying (s - 0.75). Assuming that studying hours is normally distributed, what percentage of students study less than 2.50 hours a day?
© 25.14 percent
© 19.15 percent
© 10.93 percent
© 24.86 percent
The requried, percentage of students who study less than 2.50 hours a day is approximately 25.14 percent.
What is the Z -a score?A Z-score is stated as the fractional model of data point to the mean using standard deviations.
We need to convert 2.50 hours to a standard score (z-score) using the formula,
z = (x - μ) / σ
where x is the value we want to convert, μ is the mean, and σ is the standard deviation.
z = (2.50 - 3.00) / 0.75
z = -0.67
This means that 2.50 hours is 0.67 standard deviations below the mean.
We can use a standard normal distribution table or a calculator to find the percentage of the distribution that falls below this standard score. For example, using a standard normal distribution table, we can look up the area to the left of z = -0.67 and get:
P(z < -0.67) = 0.2514
So the correct answer is (a) 25.14 percent.
