The second derivative is negative at x = 0.408, we know that this critical point corresponds to a local maximum.

Calculus uses the second derivative test as a technique to identify a function's concavity and local extrema. It entails taking a function's second derivative and checking the sign at a crucial point. A local minimum or maximum is indicated by a positive second derivative and the opposite is true for a negative second derivative.

To find the critical points of the function\(f(x) = -64x^4 + 42x - 4\), we need to find where the derivative of the function is equal to zero or undefined. Taking the derivative of f(x) gives us:

\(f'(x) = -256x^3 + 42\)

Setting\(f'(x) = 0\), we can solve for x:

\(-256x^3 + 42 = 0\\x^3 = 42/256\\x = (42/256)^(1/3) = 0.408\)

So the only critical point of the function is x = 0.408.

To apply the second derivative test, we need to take the second derivative of f'(x):

\(f''(x) = -768x^2\)

Plugging in our critical point x = 0.408, we get:

\(f''(0.408) = -768(0.408)^2 = -125.3\)

Since the second derivative is negative at x = 0.408, we know that this critical point corresponds to a local maximum.

Step-by-step explanation:

I dont know the answer sorry

the amount of $723, when earns interest at a rate of 2.9% compounded twice a year, then in 23 years it becomes $1401.95.

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially—rather than linearly—over time.

Given is a boy named Elliot who deposited $723 in a savings account which earns interest at a rate of 2.9 % compounded twice a year.

The total amount of money in the account can be calculated using the formula -

A = P(1 + r/n)^nt

From the question, we can write -

P = $723

r = 2.9% = 0.29

n = 2         [n = number of times interest applied per time period]

t = 23 years

The final amount will be -

A = 723(1 + 0.29/2) ^ 2 x 23

A = 1,401.95

Therefore, the amount of $723, when earns interest at a rate of 2.9% compounded twice a year, then in 23 years it becomes $1401.95.

3 Terms and Degree is 6

Step-by-step explanation:

3 Terms and Degree is 6

How to find degrees:

4 + 2 = 6

The slope-intercept form of (5,-3) and (4,0) is y = -3x + 12.

The slope intercept form is simply writing an equation of a line so that the slope or steepness and y-intercept i.e. where the line crosses the vertical y-axis are immediately apparent.

The slope-intercept equation is y = mx + c, where x and y are two variables, and m is slope.

Slope m = \(\frac{y2-y1}{x2-x1}\)

Let,

(x1, y1) = (5, -3)

(x2, y2) = (4, 0)

Slope (m) = \(\frac{0 - (-3) }{4 - 5}\)

                = \(\frac{3}{-1}\)

                = -3

By substituting x, y, and m values in the equation we can get the value of c.

Consider x = 4 , y = 0, m = -3

y = mx + c => 0 = (-3)4 + c

                      c = 12

Therefore, the slope-intercept form of (5,-3) and (4,0) is y = -3x + 12.

The perimeter of the front of a 10-ounce cereal box is 20 inches. The height is 2 inches more than the width. What are the width and height of the front of the box?

The upper and lower limits for the sample mean control chart are:

UCL = 6.66

LCL = 3.36

To calculate the upper and lower limits for the sample mean control chart, we need to use the given data and formulas.

Sample size (n) = 15

Sample mean values: 13.30, 3.16, 3.21, 3.30, 3.27, 3.20

Range values: 0.49, 1.41, 2, 3, 0.47, 14, 5, 6, 0.49, 0.46, 0.54

First, we calculate the average range (R-bar) using the range values:

R-bar = (Sum of ranges) / (Number of samples)

R-bar = (0.49 + 1.41 + 2 + 3 + 0.47 + 14 + 5 + 6 + 0.49 + 0.46 + 0.54) / 11

R-bar ≈ 2.86 (rounded to 2 decimal places)

Next, we use the average range (R-bar) to calculate the control limits for the sample mean chart:

Upper Control Limit (UCL) = X-double bar + A2 * R-bar

Lower Control Limit (LCL) = X-double bar - A2 * R-bar

Where X-double bar is the average of sample means and A2 is a constant based on the sample size (n). For n = 15, A2 is 0.577.

Calculating the average of sample means (X-double bar):

X-double bar = (Sum of sample means) / (Number of samples)

X-double bar = (13.30 + 3.16 + 3.21 + 3.30 + 3.27 + 3.20) / 6

X-double bar ≈ 5.01 (rounded to 2 decimal places)

Calculating the control limits:

UCL = 5.01 + 0.577 * 2.86 ≈ 5.01 + 1.65 ≈ 6.66 (rounded to 2 decimal places)

LCL = 5.01 - 0.577 * 2.86 ≈ 5.01 - 1.65 ≈ 3.36 (rounded to 2 decimal places)

Therefore, the upper and lower limits for the sample mean control chart are:

UCL = 6.66

LCL = 3.36

Step-by-step explanation:

A 99% confidence interval for the population proportion of adults who have started paying bills online in the last year, based on a survey of 3091 adults where 1413 reported doing so, is approximately (0.448, 0.492). This means that we can be 99% confident that the true population proportion falls within this interval.

To construct a confidence interval for the population proportion, we can use the formula:

CI = p ± z * sqrt((p * (1 - p)) / n)

where p is the sample proportion, z is the z-score corresponding to the desired confidence level (99% in this case), and n is the sample size.

Given that 1413 out of 3091 adults in the survey reported starting to pay bills online in the last year, the sample proportion is p = 1413/3091 ≈ 0.457.

Using a z-score for a 99% confidence level, which corresponds to approximately 2.576, and substituting the values into the formula, we can calculate the margin of error as follows:

ME = 2.576 * sqrt((0.457 * (1 - 0.457)) / 3091) ≈ 0.022

Therefore, the confidence interval is approximately 0.457 ± 0.022, which simplifies to (0.435, 0.479) when rounded to three decimal places.

Interpretation: We can be 99% confident that the true proportion of adults who have started paying bills online in the last year is between 0.448 and 0.492. This suggests that a significant portion of the adult population has transitioned to online bill payments.

Answer:

Step-by-step explanation:

The values of p1, p2, p3 that minimize Var(X) are p1 = 0, p2 = 1/3, and p3 = 2/3.

We can use the following formulas to find the variance of X:

Var(X) = E[X^2] - (E[X])^2

E[X] = p1 + 2p2 + 3p3

E[X^2] = p1 + 4p2 + 9p3

Substituting these expressions into the formula for the variance, we get:

Var(X) = p1 + 4p2 + 9p3 - (p1 + 2p2 + 3p3)^2

Simplifying this expression, we get:

Var(X) = -\((p1^2 + 2p2^2 + 3p3^2) + 2p1p2 + 6p1p3 + 4p2p3\)

To maximize Var(X), we want to maximize this expression subject to the constraint p1 + p2 + p3 = 1. We can use Lagrange multipliers to find the maximum. Let:

L(p1, p2, p3, λ) = -\((p1^2 + 2p2^2 + 3p3^2) + 2p1p2 + 6p1p3 + 4p2p3 + λ(1 - p1 - p2 - p3)\)

Taking partial derivatives and setting them equal to zero, we get:

-2p1 + 2p2 + 6p3 - λ = 0

4p1 - 4p2 + 4p3 - λ = 0

6p1 + 8p2 - 6p3 - λ = 0

p1 + p2 + p3 = 1

Solving these equations, we get:

p1 = 2/7, p2 = 3/7, p3 = 2/7, λ = 4/7

Therefore, the values of p1, p2, p3 that maximize Var(X) are p1 = 2/7, p2 = 3/7, and p3 = 2/7.

To minimize Var(X), we want to minimize the expression \(-(p1^2 + 2p2^2 + 3p3^2) + 2p1p2 + 6p1p3 + 4p2p3\) subject to the constraint p1 + p2 + p3 = 1. We can use the same Lagrange multiplier method to find the minimum. Taking partial derivatives and setting them equal to zero, we get:

-2p1 + 2p2 + 6p3 - λ = 0

4p1 - 4p2 + 4p3 - λ = 0

6p1 + 8p2 - 6p3 - λ = 0

p1 + p2 + p3 = 1

Solving these equations, we get:

p1 = 0, p2 = 1/3, p3 = 2/3, λ = 2/3

Therefore, the values of p1, p2, p3 that minimize Var(X) are p1 = 0, p2 = 1/3, and p3 = 2/3.

12/1 = 8.4/x (where x is the height from which the ball was dropped to bounce 56 inches)

12x = 470.4

x = 39.2 inches

Therefore, the tennis ball was dropped from a height of 39.2 inches to bounce 56 inches.
To solve this problem, we can set up a proportion using the given information:

(height bounced from 12 inches) / (height dropped from 12 inches) = (height bounced from unknown height) / (unknown height)

(8.4 inches) / (12 inches) = (56 inches) / (unknown height)

Step-by-step explanation:

Since there are only three possible outcomes on the spinner (1, 2, or 3), we can find the probability of spinning a 2 by subtracting the probabilities of spinning a 1 or a 3 from 1

P(2) = 1 - P(1) - P(3)

P(2) = 1 - 7/25 - 2/5

P(2) = 1 - 35/125 - 50/125

P(2) = 1 - 85/125

P(2) = 40/125

P(2) = 8/25

Therefore, the experimental probability of spinning a 2 is 8/25 or 0.32.

(A) This differential equation is not separable, but it is homogeneous since the degree of both terms in the brackets is the same and equal to \($2.$\) (B) The solution to the given differential equation is: \($$\boxed{y^2 = \frac{Cx^2}{2} - \frac{x^2}{2} \ln(1 + \frac{y^2}{x^2})}$$\) where \($C$\) is the constant of integration. (C) The solution to the initial value problem is: \($$y^2 = \frac{(2\ln(5) + 8)x^2}{2} - \frac{x^2}{2} \ln(1 + \frac{y^2}{x^2})$$\)

a) To determine whether the differential equation is separable or homogenous, let us check whether the equation can be written in the form of:

\($$N(y) \frac{dy}{dx} + M(x) = 0$$\) or in the form of:

\($$\frac{dy}{dx} = f(\frac{y}{x})$$\)

For the given equation:

\($$(x^2 + y^2) + 2xy \frac{dy}{dx} = 0$$\)

Upon dividing both sides by:

\($x^2$,$$\frac{1}{x^2}(x^2 + y^2) + 2 \frac{y}{x} \frac{dy}{dx} = 0$$or$$1 + (\frac{y}{x})^2 + 2 \frac{y}{x} \frac{dy}{dx} = 0$$\)

This equation is not separable, but it is homogeneous since the degree of both terms in the brackets is the same and equal to \($2.$\)

b) We can solve the given differential equation using the method of substitution.

First, let \($y = vx.$\)

Then, \($\frac{dy}{dx} = v + x \frac{dv}{dx}.$\)

Substituting these values into the equation, we get:

\($$x^2 + (vx)^2 + 2x(vx) \frac{dv}{dx} = 0$$$$x^2(1 + v^2) + 2x^2v \frac{dv}{dx} = 0$$$$\frac{dv}{dx} = -\frac{1}{2v} - \frac{x}{2(1 + v^2)}$$\)

Now, this differential equation is separable, and we can solve it using the method of separation of variables.

\($$-2v dv = \frac{x}{1 + v^2} dx$$$$-\int 2v dv = \int \frac{x}{1 + v^2} dx$$$$-v^2 = \frac{1}{2} \ln(1 + v^2) + C$$$$v^2 = \frac{C - \ln(1 + v^2)}{2}$$$$y^2 = \frac{Cx^2}{2} - \frac{x^2}{2} \ln(1 + \frac{y^2}{x^2})$$\)

Therefore, the solution to the given differential equation is:

\($$\boxed{y^2 = \frac{Cx^2}{2} - \frac{x^2}{2} \ln(1 + \frac{y^2}{x^2})}$$\)

where \($C$\) is the constant of integration.

c) Given the differential equation above and \($y(1) = 2,$\) we can substitute \($x = 1$ and $y = 2$\) in the solution equation obtained in part (b) to find the constant of integration \($C\).

\($$$y^2 = \frac{Cx^2}{2} - \frac{x^2}{2} \ln(1 + \frac{y^2}{x^2})$$$$2^2 = \frac{C \cdot 1^2}{2} - \frac{1^2}{2} \ln(1 + \frac{2^2}{1^2})$$$$4 = \frac{C}{2} - \frac{1}{2} \ln(5)$$$$C = 2\ln(5) + 8$$\)

Thus, the solution to the initial value problem is: \($$y^2 = \frac{(2\ln(5) + 8)x^2}{2} - \frac{x^2}{2} \ln(1 + \frac{y^2}{x^2})$$\)
