Answer:

This contradict of the chain rule.

Step-by-step explanation:

The given functions are

\(f(x)=x^2\)

\(g(x)=|x|\)

It is given that,

\((f\circ g)(x)=|x|^2=x^2\)

\((g\circ f)(x)=|x^2|=x^2\)

According to chin rule,

\((f\circ g)(c)=f(g(c))=f'(g(c)g'(c)\)

It means, \((f\circ g)(c)\) is differentiable if f(g(c)) and g(c) is differentiable at x=c.

Here g(x) is not differentiable at x=0 but both compositions are differentiable, which is a contradiction of the chain rule

To create a 240-pound mixture with 8% protein, you would need 80 pounds of soybean meal and 160 pounds of cornmeal.

To determine the amounts of soybean meal and cornmeal needed to create a 240-pound mixture with 8% protein, we can set up a system of equations based on the protein content.

Let's assume x represents the amount of soybean meal (in pounds) and y represents the amount of cornmeal (in pounds) in the mixture.

We know the following information:

1. Soybean meal is 12% protein, which means 0.12x pounds of protein come from the soybean meal.

2. Cornmeal is 6% protein, which means 0.06y pounds of protein come from the cornmeal.

3. The total weight of the mixture is 240 pounds.

4. The resulting mixture should have 8% protein, which means the protein content is 0.08 times the total weight of the mixture.

Based on the above information, we can set up the following equations:

Equation 1: x + y = 240 (total weight equation)

Equation 2: 0.12x + 0.06y = 0.08(240) (protein content equation)

Simplifying Equation 2:

0.12x + 0.06y = 19.2

Now we can solve the system of equations to find the values of x and y. Using the substitution method, we can solve Equation 1 for x:

x = 240 - y

Substituting this value into Equation 2:

0.12(240 - y) + 0.06y = 19.2

28.8 - 0.12y + 0.06y = 19.2

-0.06y = 19.2 - 28.8

-0.06y = -9.6

Dividing by -0.06:

y = -9.6 / -0.06

y = 160

Now we can substitute this value of y back into Equation 1 to find x:

x + 160 = 240

x = 240 - 160

x = 80

Therefore, to create a 240-pound mixture with 8% protein, you would need 80 pounds of soybean meal and 160 pounds of cornmeal.

Answer:

The probability of drawing a face card or a 4 is approximately 0.2885, or 28.85%.

Step-by-step explanation:

To find the probability of drawing a face card or a 4 from a well shuffled deck of 52 cards, we need to count the number of cards that are either a face card or a 4, and divide that number by the total number of cards in the deck.

There are 12 face cards in a deck (4 kings, 4 queens, and 4 jacks) and 4 cards with the number 4, but the card with 4 is also a face card (the four of hearts), so we need to subtract one card from the total. Therefore, there are 15 cards in the deck that are either a face card or a 4.

The total number of cards in the deck is 52. Therefore, the probability of drawing a face card or a 4 from a well shuffled deck of cards is:

P = number of desired outcomes / total number of possible outcomes P = 15/52 P = 0.2885 (rounded to four decimal places)

So the probability of drawing a face card or a 4 is approximately 0.2885, or 28.85%.

The standard deviation of the sampling distribution of the sample proportion (standard error) is approximately 0.0324

The standard deviation of the sampling distribution of the sample proportion, also known as the standard error, can be calculated using the formula:

Standard Error = sqrt((p * (1 - p)) / n)

Where:

p is the proportion of defective parts in the population

n is the sample size

In this case, the population size is 500 and the proportion of defective parts is 0.35. The sample size is 212.

Plugging in the values into the formula, we have:

Standard Error = sqrt((0.35 * (1 - 0.35)) / 212)

Calculating this, we get:

Standard Error = sqrt(0.22775 / 212)

Standard Error ≈ 0.0324 (rounded to four decimal places)

Therefore, the standard deviation of the sampling distribution of the sample proportion (standard error) is approximately 0.0324

Why not? Focus on the two points (0,2) and (0,4)

We have the x value x = 0 show up twice. Any time x repeats itself like this, it leads to "not a function" as the result.

In other words, the input x = 0 leads to multiple outputs y = 2 and y = 4 at the same time. A function is only possible if every x input leads to exactly one y output.

If you are a visual learner, then plot all of the points on the same xy grid. Then notice how (0,2) and (0,4) fail the vertical line test to show we don't have a function.

Side note: The y values can repeat themselves in a function.

The limit of the function lim(θ→0) sin(2θ)/θ can be estimated by using a graph.

To estimate this limit graphically, you would first plot the function y = sin(2θ)/θ on a graph with the x-axis representing θ and the y-axis representing the function value. Since θ is measured in radians, make sure your graph is set to radians as well. As θ approaches 0, observe the behavior of the function.

Based on the graph, you will notice that the function approaches a value of 2 as θ approaches 0. Therefore, lim(θ→0) sin(2θ)/θ ≈ 2.

The given system of equations is:

\(\displaystyle\sf \begin{align}2x - y &= -4\\3x - 2y &= -6\end{align}\)

To solve this system, we can use the method of elimination or substitution. Let's use the method of elimination:

First, we'll multiply the first equation by 2 to make the coefficients of \(\displaystyle\sf y\) in both equations equal:

\(\displaystyle\sf \begin{align}4x - 2y &= -8\\3x - 2y &= -6\end{align}\)

Now, we can subtract the second equation from the first equation to eliminate the variable \(\displaystyle\sf y\):

\(\displaystyle\sf (4x - 2y) - (3x - 2y) = -8 - (-6)\)

Simplifying the expression:

\(\displaystyle\sf x = -2\)

Now that we have found the value of \(\displaystyle\sf x\), we can substitute it back into either of the original equations to solve for \(\displaystyle\sf y\). Let's substitute it into the first equation:

\(\displaystyle\sf 2(-2) - y = -4\)

Simplifying the expression:

\(\displaystyle\sf -4 - y = -4\)

Solving for \(\displaystyle\sf y\):

\(\displaystyle\sf -y = 0\)

\(\displaystyle\sf y = 0\)

Hence, the solution to the system of equations is \(\displaystyle\sf x = -2\) and \(\displaystyle\sf y = 0\).

Mathematicians examine numbers with their modifications, equations and associated structures, forms and their locations, and feasible positions for these things. The term "function" indicates the connection between a collection of inputs, each of which has a corresponding output. A function is a connection of inputs and outputs where each supply leads to a specific, identifiable outcome. Each function is assigned a domain, a codomain, or a scope. The letter f is widely used to denote functions (x). The symbol for entry is an x. The four primary types of accessible capabilities are on functions, yet another skills, so multiple capabilities, in capabilities, and on operations.

f(x) = a * bx, where a and b are unknown constants. We have two places through which the function passes, which implies we have two equations:

\(f(5) = a * b^5 = 32567 f(4) = a * b^4 = 16189\)

When we divide these two equations, we get:

\(b^5 / b^4 = 32567 / 16189 b = (32567 / 16189)^(1/1) = 1.007044628\)

We may solve for a by substituting this value of b in any of the equations:

\(a = 16189 / b^4 = 16189 / (1.007044628)^4 = 14000\)

(i) To find the solution for yt in the given equation yt = yt−1 + εt + 0.3εt−1, we can rewrite it as yt - yt−1 = εt + 0.3εt−1. By applying the lag operator L, we have (1 - L)yt = εt + 0.3εt−1.

Solving for yt, we get yt = (1/L)(εt + 0.3εt−1). The solution for yt involves lag operators and depends on the values of εt and εt−1.  (ii) For the equation yt = 1.2yt−1 + εt, to find the s-step-ahead forecast Et[yt+s], we can recursively substitute the lagged values. Starting with yt = 1.2yt−1 + εt, we have yt+1 = 1.2(1.2yt−1 + εt) + εt+1, yt+2 = 1.2(1.2(1.2yt−1 + εt) + εt+1) + εt+2, and so on. The s-step-ahead forecast Et[yt+s] can be obtained by taking the expectation of yt+s conditional on the available information at time t.

To make this model stationary, we need to ensure that the coefficient on yt−1, which is 1.2 in this case, is less than 1 in absolute value. If it is greater than 1, the process will be explosive and not stationary. To achieve stationarity, we can either decrease the value of 1.2 or introduce appropriate differencing operators.

(iii) For the equation yt = yt−1 + t + εt, finding the solution for yt and the s-step-ahead forecast Et[yt+s] involves incorporating the time trend t. By recursively substituting the lagged values, we have yt = yt−1 + t + εt, yt+1 = yt + t + εt+1, yt+2 = yt+1 + t + εt+2, and so on. The s-step-ahead forecast Et[yt+s] can be obtained by taking the expectation of yt+s conditional on the available information at time t.

To make this model stationary, we need to remove the time trend component. We can achieve this by differencing the series. Taking first differences of yt, we obtain Δyt = yt - yt-1 = t + εt. The differenced series Δyt eliminates the time trend, making the model stationary. We can then apply forecasting techniques to predict Et[Δyt+s], which would correspond to the s-step-ahead forecast Et[yt+s] for the original series yt.

Let's call the height of the kite above the ground "h". Then, in the right triangle formed by Savannah, the kite, and the ground, the opposite side is "h", the adjacent side is 75 feet (the length of the string), and the angle of elevation is 32 degrees.

We can use the tangent function to find the value of "h":

tan(32) = h/75

To isolate "h", we can multiply both sides by 75:

h = 75 × tan(32)

The derivative of the function is y'(x) = 24x(x² + 8)^2.

Given: y = 4(x² + 8)^3, and f(u) = 4eu.

First, we need to find the function g(x) such that y = f(g(x)). Comparing y and f(u), we get:

4(x² + 8)^3 = 4e^(g(x))

We can deduce that g(x) must be of the form:

g(x) = ln((x² + 8)^3)

Now, let's find the derivatives f'(u) and g'(x).

f'(u) = d(4eu)/du = 4eu

g'(x) = d[ln((x² + 8)^3)]/dx = 3(x² + 8)^2 * (2x) / (x² + 8)^3 = 6x / (x² + 8)

Lastly, we'll find the derivative of the function y(x) using the chain rule:

y'(x) = f'(g(x)) * g'(x)

y'(x) = [4e^(ln((x² + 8)^3))] * [6x / (x² + 8)]

y'(x) = [4(x² + 8)^3] * [6x / (x² + 8)]

y'(x) = 24x(x² + 8)^2

So the derivative of the function y(x) is:

(b) The length of the major axis and minor axis are : 12 units and 16 units.

For the given ellipse equation x²/36 + y²/64 = 1, we can determine various properties of the ellipse.

(a) The vertices of the ellipse can be found by taking the square root of the denominators in the equation. The vertices are located at (±6, 0), which means the ellipse is elongated along the x-axis.

The foci of the ellipse can be determined using the formula c = √(a² - b²), where a and b are the lengths of the semi-major and semi-minor axes, respectively. In this case, a = 8 and b = 6, so c = √(64-36) = √28. Therefore, the foci are located at (±√28, 0).

The eccentricity of the ellipse can be calculated using the formula e = √(1 - b²/a²). Plugging in the values, we get e = √(1 - 36/64) ≈ 0.8.

(b) The length of the major axis is given by 2a, where a is the length of the semi-major axis. In this case, a = 6, so the major axis has a length of 2a = 12 units.

The length of the minor axis is given by 2b, where b is the length of the semi-minor axis. In this case, b = 8, so the minor axis has a length of 2b = 16 units.
