(2) Find the equation of the tangent plane to the surface given by x² + - y² - xz = -12 xy at the point (1,-1,3).

To parameterize the plane in R^3 containing the point (1,2,3) and parallel to the given lines, we first need to find the normal vector to the plane. Since the plane is parallel to both lines, its normal vector must be perpendicular to both of their direction vectors.

The direction vector of the first line is (1,2,3), and the direction vector of the second line is (1,-1,1). To find a vector perpendicular to both of these, we can take their cross product:
(1,2,3) x (1,-1,1) = (5,2,-3)
This vector (5,2,-3) is perpendicular to both lines and therefore is the normal vector to the plane.
Now we can use the point-normal form of the equation for a plane:
ax + by + cz = d
where (a,b,c) is the normal vector and (x,y,z) is any point on the plane. We know that (1,2,3) is a point on the plane, so we can plug in these values
5x + 2y - 3z = d
To find the value of d, we can plug in the coordinates of the given point:
5(1) + 2(2) - 3(3) = -4
So the equation of the plane is:
5x + 2y - 3z = -4
To parameterize the plane, we can choose two variables (say, s and t) and solve for the remaining variable (say, z) in terms of them. Then we can plug in any values of s and t to get points on the plane.
Solving for z in terms of s and t:
5x + 2y - 3z = -4
5x + 2y + 4 = 3z
z = (5/3)x + (2/3)y + (4/3)
We can choose any values of s and t to get points on the plane, so a possible parameterization is:
x = s
y = t
z = (5/3)s + (2/3)t + (4/3)
Alternatively, we can write this in vector form:
(r,s,t) = (s,t,5s/3 + 2t/3 + 4/3)
where (r,s,t) represents a point on the plane.

The curves intersect at two points: (1, 3) and (2, 4). The integral that represents the area of the shaded region is ∫[1, 2] (x + 2 - x) dx. The area of the shaded region, which is equal to 1 square unit.

To find the points of intersection of the curves, we need to set the equations equal to each other and solve for x. Setting y = x + 2 and y = -3x - 2 equal, we have x + 2 = -3x - 2. Solving this equation, we get 4x = -4, which gives us x = -1. Substituting this value back into either equation, we find that y = 1. Therefore, the first point of intersection is (-1, 1).

Similarly, we can find the second point of intersection by setting y = x + 2 and y = x equal. This leads to x + 2 = x, which simplifies to 2 = 0. Since this equation has no solution, there is no second point of intersection.

Now, to find the area of the shaded region, we need to consider the region between the two curves. This region is bounded by the x-values 1 and 2, as these are the x-values where the curves intersect. Therefore, the integral representing the area is ∫[1, 2] (x + 2 - x) dx. Simplifying this integral gives us ∫[1, 2] 2 dx, which evaluates to 2x ∣[1, 2] = 2(2) - 2(1) = 4 - 2 = 2. Thus, the area of the shaded region is 2 square units.

The series 1/((n+1)^2) does not allow for the application of the alternating series test.

The series (-1)^(n+1) + 1 converges by the alternating series test.

Let's analyze each series in detail:

The series (-1)^(n+2n) * -1:

This series can be written as (-1)^(3n) * (-1). We can see that the exponent (3n) is always divisible by 3, so (-1)^(3n) will alternate between 1 and -1. The series is multiplied by (-1), so the signs will alternate again. The series becomes: 1, -1, 1, -1, ...

This series satisfies the conditions for the alternating series test since the terms alternate in sign and the absolute value of the terms decreases as n increases. Therefore, the series converges by the alternating series test.

The series (-1)^(n+1) + 7:

This series does not follow the form required for the alternating series test. The alternating series test applies to series where the terms alternate in sign. However, in this series, the terms do not alternate in sign. Therefore, we cannot apply the alternating series test to determine the convergence or divergence of this series.

The series (-1)^n * cos(tn):

This series does not satisfy the requirements for the alternating series test. The alternating series test applies to series where the terms alternate in sign, but in this series, the sign of the terms depends on the value of cos(tn), which can be positive or negative. Therefore, we cannot apply the alternating series test to determine the convergence or divergence of this series.

The series (-1)^(n+1) / n^2:

This series follows the form required for the alternating series test. The terms alternate in sign, and the absolute value of the terms decreases as n increases because n^2 is in the denominator. Therefore, the series converges by the alternating series test.

The series 1/((n+1)^2):

This series does not follow the form required for the alternating series test. The alternating series test applies to series where the terms alternate in sign, but in this series, all the terms are positive. Therefore, we cannot apply the alternating series test to determine the convergence or divergence of this series.

The series (-1)^(n+1) + 1:

[tex]\sin\left(\frac{3\pi}{4}\right) - \sin(0)[/tex]

The value of sin(0) is 0, so the expression simplifies to:

[tex]\sin\left(\frac{3\pi}{4}\right)[/tex]

Since [tex]\sin\left(\frac{\pi}{2}\right) = 1[/tex], we can rewrite [tex]\sin\left(\frac{3\pi}{4}\right)[/tex] as:

[tex]\sin\left(\frac{3\pi}{4}) = \sin\left(\frac{\pi}{2}\right)[/tex]

Therefore, the definite integral evaluates to:

[tex]\int_0^{\frac{3\pi}{4}} \cos x dx = 1[/tex]

In conclusion, the definite integral of cos x over the interval [tex][0, \frac{3\pi}{4}][/tex]evaluates to 1.

The volume of the solid of revolution generated by revolving the region under the curve y = √x from x = 6 to x = 20 about the x-axis is 182π cubic units.

The volume of the solid of revolution generated by revolving the region under the curve y = √x from x = 6 to x = 20 about the x-axis is π times the integral of the square of the function. In this case, the function is y = √x, so the volume can be calculated as V = π ∫[6,20] (y^2) dx.

To find the integral, we need to express y in terms of x. Since y = √x, we can rewrite it as x = y^2. Now we can substitute y^2 for x in the integral expression: V = π ∫[6,20] (x) dx.

Evaluating the integral, we get V = π [x^2/2] from 6 to 20 = π [(20^2)/2 - (6^2)/2] = π [(400/2) - (36/2)] = π [200 - 18] = π * 182.

a) To find the derivative of y = (sin(x) / e^(2x))², we apply the quotient rule. Let u = sin(x) and v = e^(2x). Using the chain rule twice, we differentiate u and v with respect to x, and then apply the quotient rule: y' = (2 * (sin(x) / e^(2x)) * cos(x) * e^(2x) - sin(x) * 2 * e^(2x) * sin(x)) / (e^(2x))^2.

b) The equation y = e^x * cos(x) involves the product of two functions. Using the product rule, we differentiate each term separately and then add them together. Applying the chain rule for both the exponential and trigonometric functions, the derivative is given by y' = (e^x * cos(x))' = (e^x * cos(x) + e^x * (-sin(x)).

c) For y = sin(cos(x)), we have a trigonometric function as both the "outside" and "inside" operation. Applying the chain rule, the derivative is y' = cos(cos(x)) * (-sin(x)).

d) The equation y = sin(3x) involves a trigonometric function as the "inside" operation. Applying the chain rule once, we have y' = 3 * cos(3x).

e) The equation y = e^x * 2^x * sin(x) consists of three terms, each with a chain rule application. Differentiating each term separately, we obtain y' = e^x * 2^x * sin(x) + e^x * 2^x * ln(2) * sin(x) + e^x * 2^x * cos(x).

The limits are as follows: 43. 0, 44. -2/5, 45. -1/12, 46. infinity, 47. 0, 48. 1.

43. To find the limit of (x + 4) - 2x / (x + 4), we simplify the expression first. (x + 4) - 2x simplifies to 4 - x. So the limit is lim (4 - x) / (x + 4) as x approaches infinity. When x approaches infinity, the numerator approaches a finite value of 4, and the denominator also approaches infinity. Therefore, the limit is 4 / infinity, which equals 0.

44. For the limit lim (-4 / (2x + 8)), as x approaches 1, the denominator approaches 2(1) + 8 = 10. However, the numerator remains constant at -4. Therefore, the limit is -4 / 10, which simplifies to -2 / 5.

45. To find the limit lim ((2x^3 - x) / (2 - |x|)), as x approaches 0.5, we substitute the value into the expression. The numerator evaluates to (2(0.5)^3 - 0.5) = 0.375 - 0.5 = -0.125, and the denominator evaluates to 2 - |0.5| = 2 - 0.5 = 1.5. Therefore, the limit is -0.125 / 1.5, which simplifies to -1/12.

46. The limit lim (2 + x) / (1 - 1/x) as x approaches infinity can be evaluated by considering the highest power of x in the numerator and denominator. The highest power of x in the numerator is x^1, and in the denominator, it is x^0. Dividing x^1 by x^0, we get x. Therefore, the limit is 2 + x as x approaches infinity, which is infinity.

47. For the limit lim (x) as x approaches 0-, the value of x approaches 0 from the negative side. Therefore, the limit is 0.

48. The limit lim (x) as x approaches 1+ indicates that the value of x approaches 1 from the positive side. Therefore, the limit is 1.

To calculate the volume of the solid bounded below by the xy-plane, on the sides by p = 13, and above by p = ", we need to integrate the function that represents the shape of the solid.

Given that the equation of the shape is p = 6761 – 338 * 2 * 1^2, we can rewrite it as p = 6761 – 676 * 1^2.

To find the limits of integration, we need to determine the values of p where the solid intersects the planes p = 13 and p = ".

Setting p = 13, we can solve for 1:

13 = 6761 – 676 * 1^2

676 * 1^2 = 6761 - 13

676 * 1^2 = 6748

1^2 = 6748 / 676

1^2 = 10

Setting p = ", we can solve for 1:

" = 6761 – 676 * 1^2

676 * 1^2 = 6761 - "

676 * 1^2 = 6761 - 338

1^2 = 6423 / 676

1^2 ≈ 9.4985

Therefore, the limits of integration for 1 are from 1 = 0 to 1 = 10.

The volume of the solid can be calculated by integrating the function p with respect to 1 over the given limits:

V = ∫[0 to 10] (6761 – 676 * 1^2) d1

V = ∫[0 to 10] (6761 – 676) d1

To find the area formed by the two curves, we need to determine the points of intersection between them. By setting the two equations equal to each other, we can find the x-coordinate of the intersection point:

5 - x = x - 1

Simplifying the equation, we have:

2x = 6

x = 3

Substituting this x-coordinate back into either equation, we can find the corresponding y-coordinate:

y = 5 - x = 5 - 3 = 2

Therefore, the intersection point is (3, 2).

To calculate the area R, we integrate the difference between the two curves over the interval [3, 5] (the x-values where the curves intersect):

∫[3 to 5] [(5 - x) - (x - 1)] dx

Simplifying the expression, we have:

Complete question:

In a certain card​ game, the probability that a player is dealt a particular hand is 0.48. Explain what this probability means. If you play this card game 100​ times, will you be dealt this hand exactly 48 ​times? Why or why​ not?

In a certain card game, the probability of being dealt a particular hand represents the likelihood of receiving that specific hand out of all possible combinations.

The probability of being dealt a particular hand in a card game indicates the chance of receiving that specific hand out of all possible combinations. It is a measure of how likely it is for the player to get that specific combination of cards. The probability is typically expressed as a fraction, decimal, or percentage.

However, when playing the card game 100 times, it is highly unlikely that the player will be dealt the same hand exactly the same number of times. This is because the card shuffling and dealing process in the game is usually random. Each time the cards are shuffled, the order and distribution of the cards change, leading to different hands being dealt. The probability remains the same for each individual game, but the actual outcomes may vary.

To compute the given integrals, let's break them down into two parts. For integral (2), the integral of √(1-x²) dx, we can use the substitution method by letting x = sin(t). For integral (15), the integral of √(1-x^4) dx, we can use the trigonometric substitution x = sin(t).

Integral (2): To compute the integral of √(1-x²) dx, we can make the substitution x = sin(t). This substitution allows us to express dx in terms of dt, and √(1-x²) becomes √(1-sin²(t)) = √(cos²(t)) = cos(t). The integral then becomes the integral of cos(t) dt, which is sin(t) + C. Substituting x back in, we get sin⁻¹(x) + C as the final result.

Integral (15): For the integral of √(1-x^4) dx, we can use the trigonometric substitution x = sin(t). This substitution transforms the integral into the form of √(1-sin²(t)^2) cos(t) dt. By applying the identity sin²(t) = (1-cos(2t))/2, we can simplify the expression to √((1-cos²(2t))/2) cos(t) dt. Further simplifying and factoring out cos(t), we have cos(t) √((1-cos²(2t))/2) dt. Now, by using another trigonometric identity, cos²(2t) = (1+cos(4t))/2, we can rewrite the integral as cos(t) √((1-(1+cos(4t))/2)/2) dt. This simplifies to cos(t) √((1-cos(4t))/4) dt. The integral then becomes the integral of cos²(t) √((1-cos(4t))/4) dt, which can be evaluated using various techniques, such as trigonometric identities or integration by parts.

Let's break down the expression etan(x) into its component functions: f(x) = etan(x) = e^(tan(x)).

The derivative of f(x) with respect to x can be found as follows:

Therefore, the derivative of tan (x) with respect to x is e^(tan(x)) * sec^2(x).

In this case, we used the chain rule because the function etan(x) is a composition of the exponential function e^x and the tangent function tan(x). By identifying these component functions, we can apply the chain rule to find the derivative.

The definite integral of 3 S₁² using the substitution method with the limits of integration transformed is 3 / (4π).

To evaluate the definite integral of 3 S₁², we can use the substitution method with the substitution u = cos θ. This gives us du = -sin θ dθ, which we can use to transform the integral limits as well.

When θ = 0, u = cos 0 = 1. When θ = π, u = cos π = -1. So, the integral limits become:

∫[1, -1] 3 S₁² du

Next, we need to express S₁ in terms of u. Using the identity S₁² + S₂² = 1, we have:

S₁² = 1 - S₂²

= 1 - sin² θ

= 1 - (1 - cos² θ)

= cos² θ

Substituting u = cos θ, we get:

S₁² = cos² θ = u²

Therefore, our integral becomes:

∫[1, -1] 3 u² du

Integrating with respect to u and evaluating at the limits, we get:

∫[1, -1] 3 u² du = [u³]₋₁¹ = (1³ - (-1)³)3/3 = 2*3/3 = 2

Finally, we need to convert back to θ from u:

2 = ∫[1, -1] 3 S₁² du = ∫[0, π] 3 cos² θ sin θ dθ

Using the identity sin θ = d/dθ (-cos θ), we can simplify the integral:

2 = ∫[0, π] 3 cos² θ sin θ dθ

= ∫[0, π] 3 cos² θ (-d/dθ cos θ) dθ

= ∫[0, π] 3 (-cos³ θ + cos θ) dθ

= [sin θ - (1/3) sin³ θ]₋₀π

= 0

Therefore, the definite integral of 3 S₁² using the substitution method with the limits of integration transformed is:

∫[1, -1] 3 S₁² du = 3/(4π)

The differential dy of y = tan(x) is given by dy = sec^2(x) dx. Evaluating dy for x = π/4 and dx = -0.1 gives approximately dy = -0.2005.

To find the differential dy of y = tan(x), we differentiate the function with respect to x using the derivative of the tangent function. The derivative of tan(x) is sec^2(x), where sec(x) represents the secant function.

Therefore, we have dy = sec^2(x) dx as the differential of y.

To evaluate dy for a specific point, in this case, x = π/4 and dx = -0.1, we substitute the values into the differential equation. Using the fact that sec(π/4) = √2, we have:

dy = sec^2(π/4) dx = (√2)^2 (-0.1) = 2 (-0.1) = -0.2.

Thus, evaluating dy for x = π/4 and dx = -0.1 yields dy = -0.2.

A wheel that makes 30 revolutions per minute will make 0.5 revolutions per second.

To calculate the number of revolutions a wheel makes per second, we need to convert the given value of revolutions per minute into revolutions per second. There are 60 seconds in a minute, so we can divide the number of revolutions per minute by 60 to obtain the revolutions per second.

In this case, the wheel makes 30 revolutions per minute. Dividing 30 by 60 gives us 0.5, which means the wheel makes 0.5 revolutions per second. This calculation is based on the fact that the wheel maintains a constant speed throughout, completing the same number of revolutions within each unit of time.

Therefore, if a wheel is rotating at a rate of 30 revolutions per minute, it will make 0.5 revolutions per second.

The empty set can be considered as a function with an empty domain. This means that there are no input values, and therefore no output values, making the function, its domain, and its range all empty.

A function is defined as a set of ordered pairs, where each input value (from the domain) is associated with a unique output value (from the range). In the case of the empty set, there are no ordered pairs because there are no input values. Therefore, the function is empty, and its domain is also empty since there are no elements to assign as input values.

Furthermore, the range of a function is the set of all output values associated with the input values. Since there are no input values in the domain of the empty set function, there are no output values either. Consequently, the range is also empty.

In summary, the empty set can be considered a function with an empty domain. This means that there are no input values, and therefore no output values, resulting in an empty function, an empty domain, and an empty range.

The plane curve defined by the given equations does not have any critical points.

To get the critical points for the plane curve defined by the equations x(t) = t + 3t and y(t) = t - 3t, we need to obtain the values of t where the derivatives of x(t) and y(t) are equal to zero.

The problem provides information about the acceleration and initial conditions of a particle moving along an s-axis. We need to find the position function of the particle. The given acceleration function is a(t) = 12 + t - 2, and the initial conditions are v(0) = 0 and s(0) = 0.

To find the position function, we need to integrate the acceleration function twice. The first integration will give us the velocity function, and the second integration will give us the position function.

Given a(t) = 12 + t - 2, we integrate it with respect to time (t) to obtain the velocity function, v(t):

∫a(t) dt = ∫(12 + t - 2) dt.

Integrating, we get:

v(t) = 12t + (1/2)t^2 - 2t + C1,

where C1 is the constant of integration.

Next, we use the initial condition v(0) = 0 to find the value of the constant C1. Substituting t = 0 and v(0) = 0 into the velocity function, we have:

0 = 12(0) + (1/2)(0)^2 - 2(0) + C1.

Simplifying, we find C1 = 0.

Now, we have the velocity function:

v(t) = 12t + (1/2)t^2 - 2t.

To find the position function, we integrate the velocity function with respect to time:

∫v(t) dt = ∫(12t + (1/2)t^2 - 2t) dt.

Integrating, we obtain:

s(t) = 6t^2 + (1/6)t^3 - t^2 + C2,

where C2 is the constant of integration.

Using the initial condition s(0) = 0, we substitute t = 0 into the position function:

0 = 6(0)^2 + (1/6)(0)^3 - (0)^2 + C2.

Simplifying, we find C2 = 0.

Therefore, the position function of the particle is:

s(t) = 6t^2 + (1/6)t^3 - t^2.

Answer:

B: 6

Step-by-step explanation:

To find the value of x + 3, we need to solve the given equation: (x - 9)(x + 3) = -36.

Expanding the equation, we get:

x^2 - 6x - 27 = -36

Rearranging the equation and simplifying, we have:

x^2 - 6x - 27 + 36 = 0

x^2 - 6x + 9 = 0

This is a quadratic equation. We can solve it by factoring or using the quadratic formula. In this case, the equation can be factored as:

(x - 3)(x - 3) = 0

Setting each factor equal to zero, we get:

x - 3 = 0

Solving for x, we find:

x = 3

Now, to find the value of x + 3:

x + 3 = 3 + 3 = 6

Therefore, the value of x + 3 is 6. So the answer is B.

The series ∑[tex](-1)^n[/tex](n+4)/(n(n+3)) is divergent because it does not satisfy the conditions for convergence.

To determine whether the series ∑[tex](-1)^n[/tex](n+4)/(n(n+3)) is conditionally convergent, absolutely convergent, or divergent, we need to analyze its convergence behavior.

First, we can examine the absolute convergence by taking the absolute value of each term in the series. This gives us ∑ |[tex](-1)^n[/tex](n+4)/(n(n+3))|. Simplifying further, we have ∑ (n+4)/(n(n+3)).

Next, we can use a convergence test, such as the comparison test or the ratio test, to evaluate the convergence behavior. Applying the ratio test, we find that the limit of the ratio of consecutive terms is 1.

Since the ratio test is inconclusive, we can try the comparison test. By comparing the series with the harmonic series ∑ 1/n, we observe that (n+4)/(n(n+3)) < 1/n for all n > 0.

Since the harmonic series ∑ 1/n is known to be divergent, and the given series is smaller than it, the given series must also be divergent.

Therefore, the series ∑ [tex](-1)^n[/tex](n+4)/(n(n+3)) is divergent.
