Answer:

88 inches

Step-by-step explanation:

Well the bike will travel the distance of the circumference of the tire.

Circumference is 2*pi*radius or pi*diameter since the diameter is twice the radius

I guess they want is to use 22/7 for pi, which is weird, but whatever.

C = pi*d

C = 22/7*28

This gets you [tex]C = \frac{616}{7}[/tex] or 88 inches

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.

The Laurent series of cos z centered at z = 1 is: cos(z - 1) = ∑((-1)^n * ((2n C k) * z^(2n - k)))/(2n)!

To obtain the Laurent series of the function cos z centered at z = 1, we can use the known Maclaurin series expansion of the cosine function and then adjust it for the center of expansion.

The Maclaurin series expansion of cos z is given by:

cos z = ∑((-1)^n * z^(2n))/(2n)!

To center the expansion at z = 1, we can substitute z - 1 for z in the series:

cos(z - 1) = ∑((-1)^n * (z - 1)^(2n))/(2n)!

Expanding this expression using the binomial theorem, we have:

cos(z - 1) = ∑((-1)^n * ((-1)^n * (2n C k) * z^(2n - k)))/(2n)!

Simplifying further, we obtain:

cos(z - 1) = ∑((-1)^n * ((2n C k) * z^(2n - k)))/(2n)!

Answer:

d (or V in the picture) = 16

Step-by-step explanation:

Because the two triangle are similar, the ratios of each of the side lengths should be equal.  Therefore, 8/1 should be equal to d/2.

1.) Set up equality of ratios: 8/1 = d/2

2.) Cross multiply: 8*2 = d*1

3.) 16 = d

The solution to the differential equation is [tex]y = e^{-\frac{x^2}{2} + \ln(50)}[/tex]

The value of y is decreasing for x > 0.

From the question, we have the following parameters that can be used in our computation:

dy/dx = -xy

Rewrite as

dy/y = -x dx

Differentiate both sides

So, we have

ln|y| = -x²/2 + c

Take the exponent of both sides

[tex]|y| = e^{-\frac{x^2}{2} + c}[/tex]

Assume y > 0

So, we have

[tex]y = e^{-\frac{x^2}{2} + c}[/tex]

When x = 0, y = 50

So, we have

[tex]50 = e^{-\frac{0^2}{2} + c}[/tex]

Evaluate

c = ln(50)

So, we have

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

Recall that dy/dx = -xy.

This means that if dy/dx < 0, then y is decreasing.

This means that, y is decreasing for x > 0.

Step-by-step explanation:

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.

Step-by-step explanation:

Answer: 58°

Step-by-step explanation:

We know it's a right triangle, one of them must be 90°. The sum of the three interior angles are 180°, so we know the sum of the other two angles is 180 - 90 = 90°.

If one of the angles is 32°, another angle is 90 - 32 = 58°

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 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.

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]

As per the conversion in the question, £40.50 = €54

Step-by-step explanation:

Here, we want to make a conversion;

from the question;

£3 = €4

£40.50 = €x

Thus;

3 * x = 4 * 40.5

x = (4 * 40.5)/3

x = €54

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.
