The particle is at rest when the velocity is zero.

To find the values of t, you need to calculate the first derivatives of the parametric equations and set them equal to zero.

Main answer: The particle is at rest for t = 0 and t = 2.


1. Calculate the first derivatives of x(t) and y(t):
dx/dt = 3t² - 6t
dy/dt = 6t² - 6t - 12

2. Set the derivatives equal to zero and solve for t:
3t² - 6t = 0
6t² - 6t - 12 = 0

3. Factor the equations:
t(3t - 6) = 0
6(t² - t - 2) = 0

4. Solve for t:
t = 0, (3t - 6) = 0
t² - t - 2 = 0

5. From the first equation, t = 0 or t = 2.
From the second equation, use the quadratic formula:
t = (1 ± √(1 + 8))/2
t ≈ 1.41, -1.41

6. The particle is at rest for t = 0 and t = 2. The other values do not correspond to a stationary point.

All positive integers n greater than 1. Therefore, we can conclude that n! < n^n for all n > 1

a) The statement P(2) is 2! < 2^2.

b) P(2) is true since 2! = 2 < 4 = 2^2.

c) The inductive hypothesis is to assume that P(k) is true for some positive integer k.

d) In the inductive step, we need to prove that P(k+1) is true, assuming that P(k) is true.

e) To complete the inductive step, we start with the assumption that P(k) is true, which means that k! < k^k. We then need to prove that (k+1)! < (k+1)^(k+1).

(k+1)! = (k+1) * k! < (k+1) * k^k (since k! < k^k by the inductive hypothesis)

< (k+1) * (k+1)^k

= (k+1)^(k+1)

Therefore, we have shown that (k+1)! < (k+1)^(k+1), and thus P(k+1) is true.

f) By completing the basis step and inductive step, we have shown that P(n) is true for all positive integers n greater than 1. Therefore, we can conclude that n! < n^n for all n > 1.

As the marginal cost and average cost are both equal to $8 at x = 5, we can conclude that the marginal cost and average cost are equal at this production level.

To find the production level at which the average cost is a minimum, we need to first find the average cost function. The average cost function is given by:

[tex]AC(x) = C(x)/x[/tex]

Substituting C(x) from the given equation, we get:

[tex]AC(x) = (x^3 - 10x^2 + 33x)/x[/tex]

Simplifying this, we get:

[tex]AC(x) = x^2 - 10x + 33[/tex]

To find the production level at which the average cost is a minimum, we need to find the value of x that minimizes the average cost function. We can do this by taking the derivative of the average cost function and setting it equal to zero:

[tex]d/dx (x^2 - 10x + 33) = 2x - 10 = 0[/tex]

Solving for x, we get:

x = 5

Therefore, the production level at which the average cost is a minimum is x = 5.

To show that the marginal cost and average cost are equal at this production level, we need to first find the marginal cost function. The marginal cost function is given by the derivative of the cost function:

[tex]MC(x) = d/dx (x^3 - 10x^2 + 33x) = 3x^2 - 20x + 33[/tex]

Substituting x = 5, we get:

[tex]MC(5) = 3(5)^2 - 20(5) + 33 = 8[/tex]

Therefore, the marginal cost at x = 5 is $8.

To find the average cost at x = 5, we can substitute x = 5 into the average cost function:

[tex]AC(5) = 5^2 - 10(5) + 33 = 8[/tex]

Therefore, the average cost at x = 5 is also $8.

Since the marginal cost and average cost are both equal to $8 at x = 5, we can conclude that the marginal cost and average cost are equal at this production level.

If Z is between -1 and 1, then the percentage is within the 68% range. If Z is between -2 and 2, then the percentage is within the 95% range. If Z is between -3 and 3, then the percentage is within the 99.7% range.

To use the empirical rule to estimate the percentage of cold sufferers who experience symptoms for less than 9.9 days, we first need to know the mean (average) and the standard deviation of the data.

Let's assume that the mean (µ) is X days and the standard deviation (σ) is Y days. The empirical rule states that for a normal distribution:
- Approximately 68% of the data falls within 1 standard deviation (σ) of the mean (µ)
- Approximately 95% of the data falls within 2 standard deviations (σ) of the mean (µ)
- Approximately 99.7% of the data falls within 3 standard deviations (σ) of the mean (µ)

Now, we want to estimate the percentage of cold sufferers who experience symptoms for less than 9.9 days. We need to determine how many standard deviations away 9.9 days is from the mean.

To do this, use the formula:

Z = (Observed Value - Mean) / Standard Deviation
Z = (9.9 - X) / Y

Once you calculate the Z score, refer to the empirical rule:
- If Z is between -1 and 1, then the percentage is within the 68% range.
- If Z is between -2 and 2, then the percentage is within the 95% range.
- If Z is between -3 and 3, then the percentage is within the 99.7% range.

The 95% confident that the true population mean is between 220.26 and 247.74 when standard deviation σ= 55.

If the statistical model used to construct the interval is reliable, a 95% confidence interval is a range of values that is calculated from a sample of data and is anticipated to contain the real population parameter with a probability of 0.95. To put it another way, we would anticipate that 95% of the confidence intervals calculated for each sample taken from the same population will contain the true population value. A broader interval will come from a greater confidence level (such as 99%), whereas a narrower gap will result from a lower confidence level (such as 90%).

The 95% confidence interval is determined by the formula:

CI = X ± z(α/2) * (σ/√n)

Now, given α/2 (α/2 = 0.025 for a 95% confidence interval).

Thus,

CI = 234.00 ± 1.96 * (55/√65)

CI = 234.00 ± 13.74

CI = (220.26, 247.74)

Hence, the 95% confident that the true population mean is between 220.26 and 247.74.

To compute the average velocity over each time interval, we use the formula: average velocity = (h(t2) - h(t1))/(t2 - t1), where h(t) is the height function.

Using the given height function, h(t) = 34t - 4.9t^2, we calculate the average velocities:
1. [3, 3.01]:
Average Velocity = (h(3.01) - h(3))/(3.01 - 3) ≈ -17.147 m/s
2. [3, 3.001]:
Average Velocity = (h(3.001) - h(3))/(3.001 - 3) ≈ -17.194 m/s
3. [3, 3.0001]:
Average Velocity = (h(3.0001) - h(3))/(3.0001 - 3) ≈ -17.199 m/s
4. [2.99, 3]:
Average Velocity = (h(3) - h(2.99))/(3 - 2.99) ≈ -17.243 m/s
5. [2.999, 3]:
Average Velocity = (h(3) - h(2.999))/(3 - 2.999) ≈ -17.205 m/s
6. [2.9999, 3]:
Average Velocity = (h(3) - h(2.9999))/(3 - 2.9999) ≈ -17.200 m/s
To estimate the instantaneous velocity at t=3, observe the average velocities as the time intervals approach t=3:

The solution of the initial-value problem of x'=[1/2 0; 1 -1/2] x is x(t) = [4/3 * e^(t/2); 5/3 * e^t + 8/3 * e^(t/2)].

To solve the given initial value problem x'=[1/2 0; 1 -1/2] x with x(0)=[4;9], we need to find the solution of the system of differential equations.

The characteristic equation of the matrix [1/2 0; 1 -1/2] is λ^2 - (3/2)λ + (1/4) = 0, which has two distinct roots, λ_1 = 1/2 and λ_2 = 1.

The hydrostatic pressure on the bottom of the aquarium is 4015 lb/ft2. The hydrostatic pressure on the bottom of the aquarium is 96360 lb. The hydrostatic pressure on one end of the aquarium is 97440 lb.

(a) The hydrostatic pressure on the bottom of the aquarium can be found using the formula P = ρgh, where P is the pressure, ρ is the density of the fluid, g is the gravitational acceleration, and h is the depth. In this case, ρ = 62.5 lb/ft3, g = 32.2 ft/s2, and h = 2 ft. The pressure is:

P = ρgh = 62.5 lb/ft3 × 32.2 ft/s2 × 2 ft = 4015 lb/ft2

So the hydrostatic pressure on the bottom of the aquarium is 4015 lb/ft2.

(b) The hydrostatic force on the bottom of the aquarium can be found using the formula F = P A, where F is the force, P is the pressure, and A is the area. The area of the bottom of the aquarium is 6 ft × 4 ft = 24 ft2. The force is:

F = P A = 4015 lb/ft2 × 24 ft2 = 96360 lb

So the hydrostatic force on the bottom of the aquarium is 96360 lb.

(c) The hydrostatic force on one end of the aquarium can be found using the formula F = ρgAh, where A is the area of the end, which is 6 ft × 2 ft = 12 ft2. The depth of the end is 4 ft. So the force is:

F = ρgAh = 62.5 lb/ft3 × 32.2 ft/s2 × 12 ft2 × 4 ft = 97440 lb

So the hydrostatic force on one end of the aquarium is 97440 lb.

The component form of v, we need to determine its x and y components. We can use trigonometry to do this. Therefore, the component form of v is: v = (-7/4, (7/4)√3)

We know that the magnitude of v is 7/2, so we can use this information to find the length of the hypotenuse of the right triangle formed by the x and y components of v. Let h be the hypotenuse:

h = ||v|| = 7/2

Next, we can use the angle θ to determine the ratios of the sides of the right triangle:

cos(θ) = adj/h = x/7/2
sin(θ) = opp/h = y/7/2

where x is the x component of v and y is the y component of v.

Substituting in the given values, we have:

cos(150∘) = x/7/2
sin(150∘) = y/7/2

Simplifying these equations, we get:

x = -7/4
y = (7/4)√3

Therefore, the component form of v is:

v = (-7/4, (7/4)√3)

To sketch v, we can plot the point (-7/4, (7/4)√3) in the Cartesian plane. The x component is negative, so the point will be in the third quadrant. The y component is positive and greater than the x component, so the point will be above the x-axis and closer to the y-axis.

The derivative of f(x) at x = c does not exist.

To find the derivative of f(x) at x = c using the alternative form of the derivative, we first need to calculate the derivative of f(x) with respect to x.

Given that f(x) = x^3 - 2x^2 + 9, we can find the derivative of f(x) using the power rule and the constant multiple rule. The power rule states that the derivative of x^n, where n is a constant, is n*x^(n-1). The constant multiple rule states that the derivative of a constant multiplied by a function is equal to the constant multiplied by the derivative of the function.

Applying the power rule and constant multiple rule to f(x), we get:

f'(x) = 3x^2 - 4x

Now, we can evaluate f'(x) at x = c, which in this case is x = -2:

f'(-2) = 3(-2)^2 - 4(-2)

= 3(4) + 8

= 12 + 8

= 20

So, the derivative of f(x) at x = -2 is 20. However, we are asked to find the derivative at x = c = -2 using the alternative form of the derivative.

The alternative form of the derivative states that the derivative of a function at a specific point is equal to the limit of the difference quotient as x approaches the given point. In other words, the derivative at x = c is equal to the limit of (f(x) - f(c))/(x - c) as x approaches c.

Substituting c = -2 into the alternative form of the derivative, we get:

f'(-2) = lim(x->-2) (f(x) - f(-2))/(x - (-2))

However, if we try to evaluate this limit, we get an indeterminate form of 0/0. This means that the derivative of f(x) at x = -2 does not exist, as the limit of the difference quotient is undefined. Therefore, the main answer is that the derivative of f(x) at x = c does not exist.

The coefficient of x¹⁰ in (1 × x × x² × x³ × …)ⁿ is 1 for n=5 and n=10. For other values of n, the coefficient of x^10 will be 0, as there are no other possible combinations to achieve x¹⁰.

To find the coefficient of x¹⁰ in (1 × x × x² × x³ × …)ⁿ, you need to determine the possible ways to select terms from the sequence (1 × x × x² × x³ × …) such that their product is x¹⁰ and there are n terms.

Let's consider the following possible combinations of terms that can result in x^10:

1. x × x² × x² × x² × x³ (Here, n=5)
2. x² × x² × x² × x² × x² (Here, n=10)

These are the only two combinations that result in x¹⁰, assuming all powers of x are positive. For the first combination, there is only one way to select the terms, so the coefficient is 1. For the second combination, since all terms are the same, there is also only one way to select the terms, so the coefficient is 1.

Therefore, the coefficient of x¹⁰ in (1 × x × x² × x³ × …)ⁿ is 1 for n=5 and n=10. For other values of n, the coefficient of x^10 will be 0, as there are no other possible combinations to achieve x¹⁰.

The given differential equation y'' + 8y' + 16y = 0 represents a damped spring system with a damping coefficient of 8 and a spring constant of 16.

To describe the spring system represented by the differential equation y'' + 8y' + 16y = 0, we will be using the given terms.

1. Differential equation (DE): The given DE is a second-order linear homogeneous differential equation with constant coefficients. It represents the motion of a damped spring system, where y'' denotes the acceleration, y' denotes the velocity, and y denotes the displacement of the mass.

2. Damping: The term 8y' represents the damping in the spring system. It is proportional to the velocity (y') of the mass, and acts to oppose the motion, thus slowing down the oscillation.

3. Spring constant: The term 16y represents the restoring force exerted by the spring, which is proportional to the displacement (y) of the mass. The spring constant is 16.

4. Natural frequency: The natural frequency of the spring system can be found by considering the undamped case (i.e., without the 8y' term). In this case, the DE becomes y'' + 16y = 0. The natural frequency (ω_n) can be calculated as the square root of the spring constant divided by the mass (ω_n = √(k/m)). We don't have the mass value, so we can only state that ω_n = √(16/m).

5. Damping coefficient: The damping coefficient is the constant proportionality factor for the damping term. In this case, it is 8.

6. Damped frequency: Damped frequency (ω_d) is the frequency of oscillation when damping is present. It can be found using the natural frequency and the damping ratio (ζ). However, we do not have enough information to calculate the damping ratio or the damped frequency in this case.

In summary, the given differential equation y'' + 8y' + 16y = 0 represents a damped spring system with a damping coefficient of 8 and a spring constant of 16. The natural frequency depends on the mass, but the damped frequency cannot be calculated without additional information.

The order of integration does not affect the final answer, but may affect the complexity of the integrals.

To calculate the volume of the region W using triple integrals, we need to determine the bounds for each variable.

First, we can see that the planes z=0 and y=1 bound the region in the z and y directions, respectively.

Next, to find the bounds for x, we need to find the intersection of the two cylinders. Solving for y in the equation [tex]z=1-y^2[/tex], we get y = ±sqrt(1-z). Substituting this into the equation [tex]y=x^2[/tex], we get [tex]x^2[/tex] = ±sqrt(1-z), or x = ±sqrt(sqrt(1-z)). So the bounds for x are -sqrt(sqrt(1-z)) to sqrt(sqrt(1-z)).

Now we can set up the triple integrals in the three orders:

Step-by-step explanation:

ny^2 + 2y - 4 = 0

ny^2 + 2y = 4

y(ny + 2) = 4

y = 4

ny + 2 = 4

ny = 2, 0 = 2

The only possible solution to make this expression incorrect is if 0 = 2, so n is equal to 0.
