Answers

Answer 1

The driver has to stop the vehicle inside a 55-inch wide rectangular box.

The driving test requires the driver to stop with the front wheel of the vehicle inside a rectangular box drawn on the pavement. The box is 80 inches long and has a width that is 25 inches less.

A rectangular box drawn on the pavement for a driving test is 80 inches long and 25 inches less wide. Let's assume that the width of the box is w inches.

According to the problem,w = 80 - 25 = 55.

Therefore, the width of the box is 55 inches.

In the test, the driver has to stop with the front wheel of the vehicle inside the box, which means the vehicle's tire has to fit inside the box completely.

By knowing the box width is 55 inches, we can conclude that the driver has to stop the vehicle inside a 55-inch wide rectangular box.

Find the x-intercepts for the equation. Write as ordered pair(s). Write DNE if it does not exist. y=x^2−x−30

Answers

The x-intercepts of the equation y=x^2−x−30 are (-5, 0) and (6, 0).

To find the x-intercepts, we set y to zero and solve for x. Setting y=0 in the equation x^2−x−30=0, we have the quadratic equation x^2−x−30=0. We can factor this equation as (x−6)(x+5)=0. To find the x-intercepts, we set each factor equal to zero: x−6=0 and x+5=0. Solving these equations, we find x=6 and x=−5.
Therefore, the x-intercepts of the equation y=x^2−x−30 are (-5, 0) and (6, 0). This means that the graph of the equation intersects the x-axis at these points. The ordered pairs (-5, 0) and (6, 0) represent the values of x where the graph crosses the x-axis and y is equal to zero.

Given the following information for John Barker's repair shop in Ontario, we are required to calculate the HST payable or refund for the first reporting period. The HST rate for Ontario is 13%.Amount Before HST Sales $150,000 Equipment purchased $96,000 Supplies purchased $83,000 Wages paid $19,000 Rent paid $17,000Let's calculate the total HST collected from sales:

Total HST collected from Sales= HST Rate x Amount before HST Sales

Total HST collected from Sales= 13% x $150,000

Total HST collected from Sales= $19,500

Let's calculate the total ITCs for John Barker's repair shop:Input tax credits (ITCs) are the HST that a business pays on purchases made for the business. ITCs reduce the amount of HST payable. ITCs = (HST paid on eligible business purchases) - (HST paid on non-eligible business purchases)For John Barker's repair shop, all purchases are for business purposes. Hence, the ITCs are the total HST paid on purchases.

Total HST paid on purchases= HST rate x (equipment purchased + supplies purchased)

Total HST paid on purchases= 13% x ($96,000 + $83,000)

Total HST paid on purchases= $19,790

Let's calculate the net HST payable or refund:

Net HST payable/refund = Total HST collected from sales - Total ITCs

Net HST payable/refund = $19,500 - $19,790Net HST payable/refund

= -$290 Since the Net HST payable/refund is negative,

NOTE: State the open intervals as a comma separated list (if needed).

Answers

The particle's velocity is the derivative of the position function with respect to time, v(t)=ds/dt.Find the particle's velocity as a function t:      v(t) = ds/dt= d/dt(16/3)t³ − 4t² + 1= 16t² - 8t = 8t(2t - 1)

Therefore, the particle's velocity as a function of t is v(t) = 8t(2t - 1).The acceleration of the particle is the derivative of the velocity function with respect to time, a(t) = dv/dt.

The particle's acceleration as a function of t is a(t) = d/dt(8t(2t - 1)) = 16t - 8.On the interval (0,5), v(t) = 8t(2t - 1) > 0 when t > 1/2 (i.e., 0.5 < t < 5). Therefore, the particle is moving to the right on the interval (1/2,5).

Similarly, v(t) < 0 when 0 < t < 1/2 (i.e., 0 < t < 0.5).

The particle is slowing down when its acceleration is negative and speeding up when its acceleration is positive.

a(t) = 0 when 16t - 8 = 0, or t = 1/2.

Therefore, a(t) < 0 when 0 < t < 1/2 (i.e., the particle is slowing down on the interval (0,1/2)) and a(t) > 0 when 1/2 < t < 5.

Solve: ∫30x2​/√(100−x2​)dx

Answers

The solution to the integral ∫30x^2/√(100-x^2)dx is (1/3)(100-x^2)^(3/2) + C, where C is the constant of integration.

To solve the given integral, we can use a trigonometric substitution. Let's substitute x = 10sinθ, where -π/2 ≤ θ ≤ π/2. This substitution allows us to express the integral in terms of θ and perform the integration.

First, we need to find the derivative dx with respect to θ. Differentiating x = 10sinθ with respect to θ gives dx = 10cosθdθ.

Next, we substitute x and dx into the integral:

∫30x^2/√(100-x^2)dx = ∫30(10sinθ)^2/√(100-(10sinθ)^2)(10cosθ)dθ

                     = ∫3000sin^2θ/√(100-100sin^2θ)(10cosθ)dθ

                     = ∫3000sin^2θ/√(100cos^2θ)(10cosθ)dθ

                     = ∫3000sin^2θ/10cos^2θdθ

                     = ∫300sin^2θ/cos^2θdθ

Using the trigonometric identity sin^2θ = 1 - cos^2θ, we can rewrite the integral as:

∫300(1 - cos^2θ)/cos^2θdθ

= ∫300(1/cos^2θ - 1)dθ

= ∫300sec^2θ - 300dθ

Integrating ∫sec^2θdθ gives us 300tanθ, and integrating -300dθ gives us -300θ.

Putting it all together, we have:

[tex]∫30x^2/√(100-x^2)dx = 300tanθ - 300θ + C[/tex]

Now, we need to convert back to x. Recall that we substituted x = 10sinθ, so we can rewrite θ as [tex]sin^(-1)(x/10).[/tex]

Therefore, the final solution is:

[tex]∫30x^2/√(100-x^2)dx = 300tan(sin^(-1)(x/10)) - 300sin^(-1)(x/10) + C[/tex]

Note: The solution can also be expressed in terms of arcsin instead of [tex]sin^(-1)[/tex], depending on the preferred notation.

Use undetermined coefficients to find the particular solution to

yp(t)=

Answers

Using the method of undetermined coefficients, the particular solution yp(t) for the given second-order linear homogeneous differential equation is yp(t) = At^2 + Bt + C, where A, B, and C are constants to be determined.

To find the particular solution yp(t), we assume it has the form yp(t) = At^2 + Bt + C, where A, B, and C are constants. Since the right-hand side of the equation is a polynomial of degree 2, we choose a particular solution of the same form.

Differentiating yp(t) twice, we obtain yp''(t) = 2A, and yp'(t) = 2At + B. Substituting these derivatives into the differential equation, we have:

2A + 5(2At + B) + 3(At^2 + Bt + C) = 4t^2 + 8t + 4.

Expanding and grouping the terms, we have:

(3A)t^2 + (5B + 2A)t + (2A + 5B + 3C) = 4t^2 + 8t + 4.

Equating the coefficients of like terms, we get the following equations:

3A = 4, (5B + 2A) = 8, and (2A + 5B + 3C) = 4.

Solving these equations, we find A = 4/3, B = 4/5, and C = -2/15. Therefore, the particular solution is yp(t) = (4/3)t^2 + (4/5)t - 2/15.

Answers

To find the local maxima, local minima, and saddle points of the function \(f(x, y) = x^3 + y^3 + 9x^2 - 6y^2 - 9\), we need to find the critical points and classify them using the second partial derivative test.

First, let's find the critical points by setting the partial derivatives of \(f(x, y)\) equal to zero:

\(\frac{{\partial f}}{{\partial x}} =[tex]3x^2 + 18x = 0[/tex]\)  -->  \(x(x + 6) = 0\)

This gives us two possibilities: \(x = 0\) or \(x = -6\).

\(\frac{{\partial f}}{{\partial y}} = [tex]3y^2 - 12y = 0[/tex]\)  -->  \(3y(y - 4) = 0\)

This gives us two possibilities: \(y = 0\) or \(y = 4\).

Now, let's use the second partial derivative test to classify the critical points.

Taking the second partial derivatives:

\(\frac{{\[tex]partial^2[/tex] f}}{{\[tex]partial x^2[/tex]}} = 6x + 18\) and \(\frac{{\[tex]partial^2[/tex] f}}{{\[tex]partial y^2[/tex]}} = 6y - 12\).

At the point (0, 0):

\(\frac{{\partial^2 f}}{{\[tex]partial x^2[/tex]}} = 6(0) + 18 = 18 > 0\) (positive)

\(\frac{{\partial^2 f}}{{\[tex]partial y^2[/tex]}} = 6(0) - 12 = -12 < 0\) (negative)

Thus, the point (0, 0) is a saddle point.

At the point (0, 4):

\(\frac{{\[tex]partial^2[/tex] f}}{{\[tex]partial  x^2[/tex]}} = 6(0) + 18 = 18 > 0\) (positive)

\(\frac{{\[tex]partial^2[/tex] f}}{{\[tex]partial y^2[/tex]}} = 6(4) - 12 = 12 > 0\) (positive)

Thus, the point (0, 4) is a local minimum.

At the point (-6, 0):

\(\frac{{\[tex]partial^2[/tex] f}}{{\[tex]partial x^2[/tex]}} = 6(-6) + 18 = -18 < 0\) (negative)

\(\frac{{\[tex]partial^2[/tex] f}}{{\[tex]partial y^2[/tex]}} = 6(0) - 12 = -12 < 0\) (negative)

Thus, the point (-6, 0) is a saddle point.

Therefore, the local maximum occurs at the point (-6, 0), and the local minimum occurs at the point (0, 4).

Principal amount (P) = $7,000, Time (t) = 14 years and Interest compounded quarterly. We have to find the interest rate needed for an investment of $7,000 to triple in 14 years if interest is compounded quarterly.

So, let us apply the formula of compound interest which is given by;A = P (1 + r/n)^(n*t)where

A= Final amount,

P= Principal amount,

r= Annual interest rate

n= number of times the interest is compounded per year, and

t = time (in years)  So, here the final amount should be 3 times of the principal amount. Now, let us solve the above equation;21,000/7,000

= (1 + r/4)^56 (Divide by 7,000 both side)

3 = (1 + r/4)^56Take log both side; log

3 = log(1 + r/4)^56Using the property of logarithm;56 log(1 + r/4)

= log 3 Using log value;56 log(1 + r/4)

r = 4.0762 (1.01905485296 - 1)

Thus, the interest rate needed for an investment of $7,000 to triple in 14 years if interest is compounded quarterly is 4.08%.Hence, the explanation of the solution is as follows:The interest rate needed for an investment of $7,000 to triple in 14 years if interest is compounded quarterly is 4.08%.

Calculate the derivative of the function. Then find the value of the derivative as specified. f(x)= 8/x+2 ; f’(0)

Answers

The, f'(0) = 0. The derivative of the function f(x) = 8/(x + 2) at x = 0 is zero, indicating that the slope of the tangent line at x = 0 is zero.

The derivative of the function f(x) = 8/(x + 2) is f'(x) = -8/(x + 2)^2. Evaluating f'(0), we substitute x = 0 into the derivative expression and find that f'(0) = -2.

To find the derivative of the function f(x) = 8/(x + 2), we can use the power rule for differentiation. The power rule states that if we have a function of the form f(x) = x^n, the derivative is given by f'(x) = nx^(n-1).

Applying the power rule, we differentiate the function f(x) = 8/(x + 2) with respect to x. The denominator (x + 2) can be rewritten as (x + 2)^1, so we have:

f'(x) = [d/dx (8)]/(x + 2)^1

= 0/(x + 2)^1

= 0

Therefore, the derivative of f(x) = 8/(x + 2) is f'(x) = 0. This means that the rate of change of the function f(x) is constant, and the function has a horizontal tangent line at every point.

To evaluate f'(0), we substitute x = 0 into the derivative expression f'(x) = 0:

f'(0) = 0/(0 + 2)^1

Determine the curvature of the elliptic helix r=⟨9cos(t),6sin(t),5t⟩ at the point when t=0.
Now determine the curvature of the elliptic helix r=⟨9cos(t),6sin(t),5t⟩ at the point when t=π/2.

Answers

The curvature of the elliptic helix at the point when t=0 is 1/18, and the curvature at the point when t=π/2 is 1/15. The curvature measures how sharply the helix bends at a given point.

To find the curvature of the elliptic helix at a specific point, we need to compute the curvature formula using the parametric equations of the helix. The curvature formula is given by:

κ = |T'(t)| / |r'(t)|,

where κ is the curvature, T'(t) is the derivative of the unit tangent vector, and r'(t) is the derivative of the position vector.

For the given elliptic helix r(t) = ⟨9cos(t), 6sin(t), 5t⟩, we first compute the derivatives:

r'(t) = ⟨-9sin(t), 6cos(t), 5⟩,

T'(t) = r''(t) / |r''(t)|,

r''(t) = ⟨-9cos(t), -6sin(t), 0⟩.

At t=0, the position vector is r(0) = ⟨9, 0, 0⟩, and the derivatives are:

r'(0) = ⟨0, 6, 5⟩,

r''(0) = ⟨-9, 0, 0⟩.

Using these values, we can calculate the curvature at t=0:

κ = |T'(0)| / |r'(0)| = |r''(0)| / |r'(0)| = |-9| / √([tex]0^2[/tex]+ [tex]6^2[/tex] + [tex]5^2[/tex]) = 1/18.

Similarly, at t=π/2, the position vector is r(π/2) = ⟨0, 6, (5π/2)⟩, and the derivatives are:

r'(π/2) = ⟨-9, 0, 5⟩,

r''(π/2) = ⟨0, -6, 0⟩.

Using these values, we can calculate the curvature at t=π/2:

κ = |T'(π/2)| / |r'(π/2)| = |r''(π/2)| / |r'(π/2)| = |-6| / √([tex](-9)^2[/tex] +[tex]0^2[/tex]+ [tex]5^2[/tex]) = 1/15.

In conclusion, the curvature of the elliptic helix at the point when t=0 is 1/18, and the curvature at the point when t=π/2 is 1/15. These values indicate the rate of change of the tangent vector with respect to the position vector and describe the sharpness of the helix's curvature at those points.

The rules of differentiation to determine the value of the variable f'(6), which corresponds to the function f(x) = (1/4)g(x) + (1/5)h(x). As we know that g'(6) equals 4 and h'(6) equals 12, the value of f'(6) for the function that was given is equal to 3.4.

To begin, we will use the sum rule of differentiation, which states that the derivative of the sum of two functions is equal to the sum of their derivatives. We will then proceed to use the sum rule of differentiation. By applying the concept of differentiation to the expression f(x) = (1/4)g(x) + (1/5)h(x), we are able to determine that f'(x) = (1/4)g'(x) + (1/5)h'(x).

When we plug in the known values of g'(6) being equal to 4 and h'(6) being equal to 12, we get the expression f'(x) which is equal to (1/4)(4) plus (1/5)(12). After simplifying this expression, we get f'(x) equal to 1 plus (12/5) which is equal to 1 plus 2.4 which is equal to 3.4.

In order to find f'(6), we finally substitute x = 6 into f'(x), which gives us the answer of 3.4 for f'(6).

As a result, the value of f'(6) for the function that was given is equal to 3.4.

Problem 1. Integration by Trapezoidal Rule. Write a computer program to integrate the function \( I=\int_{0}^{\pi / 2} \sin (x) d x \) by using the Trapezoidal rule. Compare with the exact result \( I

Answers

The absolute error between the approximate result obtained by trapezoidal rule and exact result is 0.0015.

The formula for trapezoidal rule is given as: \[\int_{a}^{b}f(x)dx \approx \frac{(b-a)}{2} (f(a)+f(b))\]

We will use the above formula for the given integral \(I=\int_{0}^{\pi / 2} \sin (x) d x\).

Now using trapezoidal rule we can write the integral as, \[\int_{0}^{\pi / 2} \sin (x) d x\] \[\approx \frac{(\pi/2-0)}{2} (\sin(0)+\sin(\pi/2))\] \[\approx 0.9985\]

Now we can find the exact result of the integral as, \[I=\int_{0}^{\pi / 2} \sin (x) d x=-\cos(x)|_{0}^{\pi / 2}\] \[= -\cos(\pi/2)+\cos(0)\] \[= 1\]

Therefore, the exact result of the given integral is \(I=1\).

Comparing the result obtained by trapezoidal rule and exact result we have, \[Absolute Error=|Exact Value-Approximate Value|\] \[= |1-0.9985|\] \[=0.0015\].

Answers

When a scatterplot is created from a table of values, the correct statement is: It is possible for two points to have the same x-coordinate and the same y-coordinate.

In a scatterplot, each point represents a specific pair of values, typically an x-coordinate and a corresponding y-coordinate. It is entirely possible for two or more data points to have identical x-coordinates and y-coordinates, resulting in overlapping points on the scatterplot.

Points with the same x-coordinate but different y-coordinates indicate a vertical distribution, while points with the same y-coordinate but different x-coordinates indicate a horizontal distribution. However, it is also possible for points to have the same x-coordinate and the same y-coordinate, resulting in points that lie directly on top of each other when plotted.

Therefore, the statement that allows for the possibility of two points having the same x-coordinate and the same y-coordinate is correct.

Answers

The value of y when x=1 cannot be determined with the given information. Therefore, none of the options (a, b, c, d) can be selected.

To predict the value of the y variable when x=1 using the given model and parameter estimates, we substitute the values into the equation:

ln(y) = β1 + β2 ln(x) + u1

Given parameter estimates:

β1 = 2

β2 = 1

Substituting x=1 into the equation:

ln(y) = 2 + 1 ln(1) + u1

Since ln(1) is equal to 0, the equation simplifies to:

ln(y) = 2 + 0 + u1

ln(y) = 2 + u1

To obtain the approximate value of y, we need to take the exponential of both sides of the equation:

y = e^(2 + u1)

Since we don't have information about the value of the error term u1, we can't provide an exact value for y when x=1. Therefore, none of the given options (a, b, c, d) can be determined based on the provided information.

Task 1: Attitude Problems The reference frame transformation from the LVLH frame to the body frame is usually handled through the use of either Euler angles or quaternions. (a) Write a function in MAT

Answers

In the context of spaceflight, the LVLH frame (Local Vertical/Local Horizontal) is often used as the reference frame for describing the attitude of a spacecraft.

The body frame, on the other hand, is the reference frame fixed to the spacecraft itself. The transformation between these frames is critical for performing operations such as attitude control or maneuver planning.In order to transform between the LVLH frame and the body frame, either Euler angles or quaternions are typically used. Euler angles are a set of three angles that describe a sequence of rotations around the principal axes of the reference frame. Quaternions are a set of four numbers that can be used to describe an orientation in three dimensions. Both methods have their advantages and disadvantages depending on the specific application at hand.To write a function in MATLAB for this transformation, the specific equations for the transformation must first be derived. Once these equations are known, they can be implemented in a function that takes as input the desired transformation and outputs the resulting attitude of the spacecraft. The function can then be tested and verified using simulation or experimental data to ensure that it is functioning correctly.

In conclusion, the transformation between the LVLH frame and the body frame is a critical operation for spacecraft attitude control and maneuver planning. Both Euler angles and quaternions can be used for this transformation, and the specific method chosen will depend on the application at hand. To implement this transformation in MATLAB, the equations must first be derived and then implemented in a function that can be tested and verified.

To compute the integral ∫sin⁶(17x)cos⁵(17x) dx, we can use trigonometric identities and integration by substitution.

Let's start by using the identity sin²θ = (1/2)(1 - cos(2θ)) to rewrite sin⁶(17x) as (sin²(17x))³:

∫sin⁶(17x)cos⁵(17x) dx = ∫(sin²(17x))³cos⁵(17x) dx.

Now, let's make a substitution u = sin(17x), which implies du = 17cos(17x) dx:

∫(sin²(17x))³cos⁵(17x) dx = (1/17) ∫u³(1 - u²)² du.

(1/17) ∫(u³ - 2u⁵ + u⁷) du.

Now, let's integrate each term separately:

Integrating each term:

(1/17) [(1/4)u⁴ - (2/6)u⁶ + (1/8)u⁸] + C,

Q4) Using Laplace Transform find \( v_{o}(t) \) in the circuit below if \( v_{r}(0)=2 V \) and \( i(0)=1 A \).

Answers

The expression for [tex]v_0(t)[/tex] is [tex]v_0(t) = 4 + 2e^{(-t)}[/tex]. In the voltage output [tex]v_0(t)[/tex] in the circuit is given by [tex]v_0(t) = 4 + 2e^{(-t)}[/tex] by using Laplace Transform.

The voltage output [tex]v_0(t)[/tex] in the circuit can be found using the Laplace Transform method. To apply the Laplace Transform, we need to convert the circuit into the Laplace domain by representing the elements in terms of their Laplace domain equivalents.

Given:

[tex]vs(t) = 4e^{(-2tu(t))[/tex] - The input voltage

i(0) = 1 - Initial current through the inductor

[tex]v_0(0) = 2[/tex] - Initial voltage across the capacitor

R = 2Ω - Resistance in the circuit

The Laplace Transform of the input voltage vs(t) is [tex]V_s(s)[/tex], the Laplace Transform of the output voltage v0(t) is [tex]V_0(s)[/tex], and the Laplace Transform of the current through the inductor i(t) is I(s).

To solve for v0(t), we can apply Kirchhoff's voltage law (KVL) to the circuit in the Laplace domain. The equation is as follows:

[tex]V_s(s) = I(s)R + sL*I(s) + V_0(s)[/tex]

Substituting the given values, we have:

[tex]4/s + 2I(s) + V_0(s) = I(s)2 + s1/s*I(s) + 2/s[/tex]

Rearranging the equation to solve for V_0(s):

[tex]V_0(s) = 4/s + 2I(s) - 2I(s) - s*I(s)/s + 2/s\\= 4/s + 2/s + 2I(s)/s - sI(s)/s\\= (6 + 2I(s) - sI(s))/s[/tex]

To obtain v0(t), we need to take the inverse Laplace Transform of [tex]V_0(s)[/tex] However, we don't have the expression for I(s). To find I(s), we can apply the initial conditions given:

Applying the initial condition for the current through the inductor, we have:

[tex]I(s) = sLi(0) + V_0(s)\\= 2s + V_0(s)[/tex]

Substituting this back into the equation for  [tex]V_0(s)[/tex]:

[tex]V_0(s) = (6 + 2(2s + V_0(s)) - s(2s + V_0(s)))/s[/tex]

Simplifying further:

[tex]V_0(s) = (6 + 4s + 2V_0(s) - 2s^2 - sV_0(s))/s[/tex]

Rearranging the equation to solve for [tex]V_0(s)[/tex]:

[tex]V_0(s) + sV_0(s) = 6 + 4s - 2s^2\\V_0(s)(1 + s) = 6 + 4s - 2s^2\\V_0(s) = (6 + 4s - 2s^2)/(1 + s)[/tex][tex]i(0) = 1v_0(0) = 2[/tex]

Now, we can take the inverse Laplace Transform of [tex]V_0[/tex](s) to obtain [tex]v_0(t)[/tex]:

[tex]v_0(t)[/tex]  = Inverse Laplace Transform{[tex](6 + 4s - 2s^2)/(1 + s)[/tex]}

The expression for [tex]v_0(t)[/tex] is the inverse Laplace Transform of [tex](6 + 4s - 2s^2)/(1 + s)[/tex]. To find the inverse Laplace Transform of this expression, we need to decompose it into partial fractions.

The numerator of the expression is a quadratic polynomial, while the denominator is a linear polynomial. We can start by factoring the denominator:

1 + s = (1)(1 + s)

Now, we can express the expression as:

[tex](6 + 4s - 2s^2)/(1 + s) = A/(1) + B/(1 + s)[/tex]

To determine the values of A and B, we can multiply both sides by the denominator and equate the coefficients of the like terms on both sides. After performing the algebraic manipulation, we get:

[tex]6 + 4s - 2s^2 = A(1 + s) + B(1)[/tex]

Simplifying further:

[tex]6 + 4s - 2s^2 = A + As + B[/tex]

Comparing the coefficients of the like terms, we have the following equations:

[tex]-2s^2: -2 = 0[/tex]

4s: 4 = A

6: 6 = A + B

From the equation [tex]-2s^2 = 0[/tex], we can determine that A = 4.

Substituting A = 4 into the equation 6 = A + B, we can solve for B:

6 = 4 + B

B = 2

Now that we have the values of A and B, we can express the expression as:

[tex](6 + 4s - 2s^2)/(1 + s) = 4/(1) + 2/(1 + s)[/tex]

Taking the inverse Laplace Transform of each term separately, we get:

Inverse Laplace Transform(4/(1)) = 4

Inverse Laplace Transform[tex](2/(1 + s)) = 2e^{(-t)}[/tex]

Therefore, the expression for [tex]v_0(t)[/tex] is [tex]v_0(t) = 4 + 2e^{(-t)}[/tex].

Answers

By analyzing the velocity and acceleration functions and their respective signs, we can answer the questions related to the particle's motion.

a) The particle is at rest when its velocity is equal to zero. To find the times when the particle is at rest, we need to determine the values of 't' that satisfy the equation v(t) = s'(t) = 0. The velocity function is the derivative of the position function, so we can find the velocity function by taking the derivative of s(t).

b) The particle is moving in the negative direction when its velocity is negative. To find the times when the particle is moving in the negative direction, we need to determine the values of 't' that satisfy the condition v(t) < 0.

c) The acceleration is the derivative of the velocity function. To find the velocity when the acceleration is 0, we need to solve the equation a(t) = v'(t) = 0.

d) To determine if the object is speeding up or slowing down at t = 3, we need to evaluate the sign of the acceleration at that time. If the acceleration is positive, the object is speeding up; if the acceleration is negative, the object is slowing down.

Answers

The equation for the number of bacteria B in terms of hours t can be written as: [tex]B(t) = 100 * (2)*(t/30)[/tex]

Based on the given information, we can determine that the number of bacteria in the culture is expected to double every 30 hours. Let's denote the number of bacteria at any given time t as B(t).

Initially, there are 100 bacteria in the culture, so we have:

B(0) = 100

Since the number of bacteria is expected to double every 30 hours, we can express this as a growth rate. The growth rate is 2 because the number of bacteria doubles.

Therefore, the equation for the number of bacteria B in terms of hours t can be written as:

B(t) = 100 * (2)^(t/30)

In this equation, (t/30) represents the number of 30-hour intervals that have passed since the experiment began. We divide t by 30 because every 30 hours, the number of bacteria doubles.

The minimum film thickness:

The minimum film thickness h min can be calculated from the following formula:  

Here, W = Load on the bearing journal,

V = Total oil flow through the bearing,

μ = Coefficient of friction,

and U = Surface velocity of the journal.

For a minimum clearance assembly, the total clearance will be

Cmin = -0.0006 + 0.0014

= 0.0008 in

Therefore, the minimum film thickness is:

hmin = (0.0008*8.5*670)/(2955.8823*0.6)

= 0.0031 in.

The coefficient of friction:

μ = W/(hmin*V*U)

= (670)/(0.0031*0.6*2955.8823*1)

= 0.0588.

The coefficient of friction is 0.0588.

The total oil flow:

The total oil flow Q can be calculated from the following formula:

Q = V * π/4 * D^2 * N

Here, D = Journal diameter,

N = Rotational speed of the journal.

The diameter of the journal is 1 inch.

Thus, the oil flow will be

Q = 0.6 * π/4 * 1^2 * 2955.8823

= 411.6 in³/s (approximately).

Hence, the total oil flow is approximately 411.6 in³/s.

Exercise 5-13 (Algo) Compare the allowance method and the direct write-off method (LO5-6) At the beginning of 2024 , Best Heating & Air (BHA) has a balance of $25,700 in accounts receivable. Because BHA is a privately owned company, the company has used only the direct write-off method to account for uncollectible accounts. However, at the end of 2024. BHA wishes to obtain a loan at the local bank, which requires the preparation of proper financial statements. This means that BHA now will need to use the allowance method. The following transactions occur during 2024 and 2025. 1. During 2024. install air conditioning systems on account, $187,000 2. During 2024, collect $182,000 from customers on account. 3. At the end of 2024 , estimate that uncollectible accounts total 15% of ending accounts receivable. 4. In 2025 , customers' accounts totaling $3.800 are written off as uncollectible. Required: 1. Record each transaction using the allowance method. 2. Record each transaction using the direct write-off method. 3.
