The family will travel approximately 0.0037075 miles in Total.
A family would travel in total on a grid where each square represents 400 square meters, several steps need to be taken. First, we need to determine the area covered by the family.
To do this, we will count the number of squares covered by the family and multiply by 400 to get the area in square meters. Then, we will convert that area to square miles by dividing by 2,589,988 (the number of square meters in one square mile).
Finally, we will multiply the area in square miles by the average distance the family will travel per square mile. Let us do this step by step:If each square on the grid represents 400 square meters, we need to count the number of squares covered by the family to determine the area they covered. From the grid, it can be seen that the family covered 12 squares. Therefore, the area covered by the family is 12 × 400 = 4800 square meters.
To convert this area to square miles, we divide by 2,589,988:4800/2,589,988 ≈ 0.00185375 square miles. Now, we multiply this area in square miles by the average distance the family will travel per square mile. Let's assume the family walks 2 miles per square mile. Therefore, the total distance they will travel is 0.00185375 × 2 = 0.0037075 miles.
Therefore, the family will travel approximately 0.0037075 miles in total.

The fixed costs for a company are $1,596.00 per month, and their variable cost per unit is $3.20. Suppose the company insists on producing 140 units, the selling price per unit required to break even is $
When the company insists on producing 140 units then the selling price per unit required to break even is approximately $14.60.
To calculate the selling price per unit required to break even, we need to consider the fixed costs, variable cost per unit, and the desired production quantity.
Given:
Fixed costs = $1,596.00 per month
Variable cost per unit = $3.20
Production quantity = 140 units
To break even, the total revenue should cover both the fixed costs and the variable costs.
The total cost can be calculated as follows:
Total cost = Fixed costs + (Variable cost per unit × Production quantity)
Plugging in the given values:
Total cost = $1,596.00 + ($3.20 × 140)
Total cost = $1,596.00 + $448.00
Total cost = $2,044.00
To break even, the total revenue should be equal to the total cost.
The selling price per unit required to break even can be calculated as:
Selling price per unit = Total cost / Production quantity
Plugging in the values:
Selling price per unit = $2,044.00 / 140
Selling price per unit ≈ $14.60
Therefore, the selling price per unit required to break even is approximately $14.60.

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line.
y = 5x^3, y = 5x, x ≥ 0; about the x-axis
V=?
Sketch the region.
Sketch the solid, and a typical disk or washer.
The volume (V) of the solid obtained by rotating the region bounded by the curves y = 5x^3, y = 5x, x ≥ 0 about the x-axis is V = ∫[0,1] 2πx((5x) - (5x^3))dx.
To find the volume of the solid, we can use the method of cylindrical shells. We will integrate the volume of each shell as it rotates around the x-axis.
First, let's sketch the region bounded by the curves. The curve y = 5x^3 intersects with the line y = 5x at two points: (0, 0) and (1, 5). The region between these curves is bounded by the x-axis and the curves. It looks like a "bowl" shape, opening upwards, with the bottom touching the x-axis.
Next, let's visualize a typical cylindrical shell. Imagine taking a thin strip of thickness Δx at a distance x from the x-axis. When this strip rotates around the x-axis, it forms a cylindrical shell. The height of this shell is the difference between the two curves: (5x) - (5x^3). The circumference of the shell is 2πx since it is the distance around the axis of rotation. The thickness of the shell is Δx.
The volume of the shell is given by V_shell = 2πx((5x) - (5x^3))Δx. To find the total volume, we need to sum up all these shells by integrating with respect to x.
Integrating V_shell from x = 0 to x = 1, we get V = ∫[0,1] 2πx((5x) - (5x^3))dx.
Evaluating this integral will give us the volume of the solid obtained by rotating the region about the x-axis.

The function is not symmetric about the y-axis or the origin, which is consistent with the conclusion that it is neither odd nor even. A function can be categorized as odd, even or neither depending on its symmetry about the y-axis and the origin of the graph.
To determine whether a function is odd, even or neither, we need to check whether the function satisfies the following conditions:If f(-x) = f(x), then the function is evenIf f(-x) = -f(x), then the function is oddIf f(-x) ≠ f(x) and f(-x) ≠ -f(x), then the function is neither.
Now let's evaluate whether the given function f(x) = 3 − 4|x| is even, odd or neither. Evaluating f(-x) and f(x) :f(-x) = 3 - 4|(-x)|f(-x) = 3 + 4|x|Comparing the value of f(-x) and f(x) :f(-x) ≠ f(x) and f(-x) ≠ -f(x).

Let C be a closed contour and let zo ∈ C be a point not lying on C. The winding number of C about zo is defined by the integral.
n(C,zo) = 1/2πi ∫ 1/(z-zo)dz.
The winding number of a closed contour C about a point zo is defined as the integral of the function 1/(z - zo) over the contour C, divided by 2πi.
The winding number, denoted as n(C, zo), measures how many times the contour C wraps around the point zo in the counterclockwise direction. It is a topological property of the contour and is an integer value.
To calculate the winding number, we evaluate the integral 1/(z - zo)dz along the contour C. The contour must be positively oriented (counterclockwise) and enclose the point zo. The integral measures the net change in the argument of the complex number z - zo as we traverse the contour.
The value of the integral divided by 2πi gives us the winding number, which represents the number of times the contour wraps around the point zo in the counterclockwise direction.

Step-by-step explanation:
The following differential equation describes the movement of a body with a mass of 1 kg in a mass-spring system, where y(t) is the vertical position of the body in meters) at time t. y" + 4y + 5y = -21 To determine the position of the body at time t complete the following steps. (a) Write down and solve the characteristic (auxiliary) equation. (b) Determine the complementary solution, yc, to the corresponding homogeneous equation, y" + 4y' + 5y = 0. (c) Find a particular solution, Yp, to the nonhomogeneous differential equation, Y" + 4y' + 5y = e-21. Hence state the general solution to the nonhomogeneous equation as y = Ye + yp. (d) Solve the initial value problem if the initial position of the body is 1 m and its initial velocity is zero.
After considering the given data we conclude that
a) r = -2 + i and r = -2 - i value generated after solving the auxiliary equation
b)[tex]y_c = c_1e^{(-2t)} cos(t) + c_2e^{(-2t)} sin(t)[/tex] complementary solution
c) general solution to the nonhomogeneous equation is [tex]y = y_c + Y_p = c_1e^{(-2t)} cos(t) + c_2e^{(-2t)} sin(t) + (1/26)e^{(-21)} .[/tex]
d) initial value problem is [tex]y(t) = e^{(-2t)} (cos(t) + 2sin(t))/2 + (1/26)e^{(-21)} .[/tex]
To determine the position of the body at time t, we can apply the given differential equation to solve for y(t). To do this, we can follow the steps below:
(a) the characteristic (auxiliary) equation is
The characteristic equation is obtained by setting the coefficients of the differential equation to zero, which gives us the equation [tex]r^2 + 4r + 5 = 0.[/tex]Solving this quadratic equation, we get r = -2 + i and r = -2 - i.
(b) evaluate the complementary solution, yc, to the corresponding homogeneous equation, [tex]y" + 4y' + 5y = 0.[/tex]
The complementary solution is given by[tex]y_c = c_1e^{(-2t)} cos(t) + c_2e^{(-2t)} sin(t),[/tex]where [tex]c_1[/tex] and [tex]c_2[/tex] are constants determined by the initial conditions.
(c) Calculate a particular solution, Yp, to the nonhomogeneous differential equation, [tex]Y" + 4y' + 5y = e^{(-21)}[/tex]. Hence state the general solution to the nonhomogeneous equation as [tex]y = y_c + y_p.[/tex]
To describe a particular solution, we can use the method of undetermined coefficients and guess a solution of the form [tex]Yp = Ae^{(-21)}[/tex], where A is a constant to be determined.
Staging this into the differential equation, we get A = 1/26. Therefore, the particular solution is [tex]Y_p = (1/26)e^{(-21)}[/tex]. The general solution to the nonhomogeneous equation is [tex]y = y_c + Y_p = c_1e^{(-2t)} cos(t) + c_2e^{(-2t)} sin(t) + (1/26)e^{(-21)}[/tex]
(d) Solve the initial value problem if the initial position of the body is 1 m and its initial velocity is zero.
Applying the initial conditions, we can solve for the constants [tex]c_1[/tex] and [tex]c_2[/tex] in the complementary solution. Since the initial velocity is zero, we have [tex]y'(0) = -2c_1 + c_2 = 0[/tex], which gives us [tex]c_2 = 2c_1.[/tex]
Applying the initial position, we have [tex]y(0) = c_1 = 1[/tex], which gives us [tex]c_2 = 2.[/tex]Therefore, the solution to the initial value problem is [tex]y(t) = e^{(-2t)} (cos(t) + 2sin(t))/2 + (1/26)e^{(-21)}[/tex]

c = ln(50)
So, we have
[tex]y = e^{-\frac{x^2}{2} + \ln(50)}[/tex]

The probability which is in a random sample of 133 people from State College, more than 50 are not college students is 0.0000313 (rounded to 4 decimal places).
Given that in State College, Pennsylvania, the proportion of college students in the population is 71.1%.
We need to find the probability that in a random sample of 133 people from State College, more than 50 are not college students.
We need to round the final answer to at least 4 decimal places and intermediate z-value calculations to 2 decimal places.
The proportion of college students in State College, Pennsylvania is 71.1%.
Therefore, the proportion of non-college students in State College, Pennsylvania is 100% - 71.1% = 28.9%.
Let X be the number of non-college students in a sample of 133 people from State College, Pennsylvania.
As the sample is random, X follows the binomial distribution with parameters n = 133 and p = 0.289.
The probability of getting more than 50 non-college students can be obtained using the normal distribution approximation to the binomial distribution.
Using the normal distribution approximation, we can convert the binomial distribution to a standard normal distribution using the following formula: Z = (X - np) / sqrt(npq)
Where q = 1 - p is the proportion of college students in the population, and np = 133 x 0.289
= 38.397 and npq = 133 x 0.289 x 0.711 = 9.728.
The probability of getting more than 50 non-college students is : P(X > 50)
= P(Z > (50 - 38.397) / sqrt(9.728))
= P(Z > 3.92)
= 0.0000313 (rounded to 4 decimal places).

Find any vertical or slant asymptotes. Consider the following.
f(x) = x^3/ (x² - 49)
The function [tex]f(x) = x^3 / (x^2 - 49)[/tex]has a vertical asymptote at x = 7 and x = -7. There are no slant asymptotes. To find the vertical asymptotes of the function f(x), we need to identify the values of x for which the denominator becomes zero, as division by zero is undefined.
In this case, the denominator is (x² - 49). To determine when it equals zero, we set it equal to zero and solve for x:
x² - 49 = 0
This equation can be factored as the difference of squares:
(x - 7)(x + 7) = 0
Setting each factor equal to zero, we find that x = 7 and x = -7. Therefore, the function has vertical asymptotes at x = 7 and x = -7.
On the other hand, to determine if there are any slant asymptotes, we need to check if the degree of the numerator (x³) is greater than the degree of the denominator [tex](x^2 - 49)[/tex]. In this case, the degree of the numerator is 3, while the degree of the denominator is 2. Since the degree of the numerator is greater, there are no slant asymptotes for this function.
In summary, the function [tex]f(x) = x^3 / (x^2 - 49)[/tex] has vertical asymptotes at x = 7 and x = -7. There are no slant asymptotes.

c) The correct interpretation of the mean is: Out of every 27 people, on average, 2.43 of them are left-handed.
d) The standard deviation is approximately 1.49
a) The random variable is X, which represents the number of 27 randomly selected people that are left-handed.
b) Given values:
n = 27 (sample size)
p = 0.09 (probability of a person being left-handed)
c) To compute the mean, you can multiply the sample size by the probability:
Mean (μ) = n * p
μ = 27 * 0.09 = 2.43
The correct interpretation of the mean is:
Out of every 27 people, on average, 2.43 of them are left-handed.
d) To compute the standard deviation (σ), you can use the formula for the binomial distribution:
Standard Deviation (σ) = √(n * p * (1 - p))
σ = √(27 * 0.09 * (1 - 0.09))
σ = √(2.43 * 0.91)
σ ≈ √2.2153
σ ≈ 1.49 (rounded to 2 decimal places)
