∂z/∂s = 3cos(t)/y, ∂z/∂t = 3s*cos(t)/y - sin(s)/x (using the chain rule to differentiate each term and substituting the given expressions for x and y)

To find ∂z/∂s and ∂z/∂t using the chain rule, we start by finding the partial derivatives of z with respect to x and y, and then apply the chain rule.

First, let's find ∂z/∂x and ∂z/∂y.

∂z/∂x = ∂/∂x [ln(5x^3y)]

= (1/5x^3y)  ∂/∂x [5x^3y]

= (1/5x^3y) 15x^2y

= 3/y

∂z/∂y = ∂/∂y [ln(5x^3y)]

= (1/5x^3y) ∂/∂y [5x^3y]

= (1/5x^3y)  5x^3

= 1/x

Now, using the chain rule, we can find ∂z/∂s and ∂z/∂t.

∂z/∂s = (∂z/∂x)  (∂x/∂s) + (∂z/∂y)  (∂y/∂s)

= (3/y)  (cos(t)) + (1/x)  (0)

= 3cos(t)/y

∂z/∂t = (∂z/∂x)  (∂x/∂t) + (∂z/∂y)  (∂y/∂t)

= (3/y) * (scos(t)) + (1/x)  (-sin(s))

= 3scos(t)/y - sin(s)/x

Therefore, ∂z/∂s = 3cos(t)/y and ∂z/∂t = 3s*cos(t)/y - sin(s)/x.

The general equation of the straight line passing through point A perpendicularly to vector AB is y - (-3) = -1/2(x - 2), and the general equation of the straight line passing through point B parallel to vector AB is y - (-1) = 2(x - 3).

To find the equation of a straight line passing through point A perpendicular to vector AB, we first need to determine the slope of vector AB. The slope is given by (change in y)/(change in x). So, slope of AB = (-1 - (-3))/(3 - 2) = 2/1 = 2. The negative reciprocal of 2 is -1/2, which is the slope of a line perpendicular to AB. Using point-slope form, the equation of the line passing through A can be written as y - y₁ = m(x - x₁), where (x₁, y₁) is point A and m is the slope. Plugging in the values, we get the equation of the line passing through A perpendicular to AB as y - (-3) = -1/2(x - 2).

To find the equation of a straight line passing through point B parallel to vector AB, we can directly use point-slope form. The equation will have the same slope as AB, which is 2. Using point-slope form, the equation of the line passing through B can be written as y - y₁ = m(x - x₁), where (x₁, y₁) is point B and m is the slope. Plugging in the values, we get the equation of the line passing through B parallel to AB as y - (-1) = 2(x - 3).

The limits for the function g(x) are as follows: a) The limit as x approaches 5 exists and is equal to -2. b) The limit as x approaches 4 does not exist. c) The limit as x approaches 0 exists and is equal to -6. d) The limit as x approaches 3.4 exists and is equal to -6.

a) To find the limit as x approaches 5, we examine the behavior of the function as x gets arbitrarily close to 5. From the graph, we can see that as x approaches 5 from both sides, the function approaches a y-value of -2. Therefore, the limit as x approaches 5 is -2.

b) The limit as x approaches 4 does not exist because as x gets closer to 4 from the left side, the function approaches a y-value of -8, while from the right side, it approaches a y-value of -6. Since the function does not approach a single value from both sides, the limit does not exist.

c) The limit as x approaches 0 exists and is equal to -6. As x approaches 0 from both sides, the function approaches a y-value of -6. Therefore, the limit as x approaches 0 is -6.

d) The limit as x approaches 3.4 exists and is equal to -6. From the graph, we can see that as x approaches 3.4 from both sides, the function approaches a y-value of -6. Thus, the limit as x approaches 3.4 is -6.

After considering the given data we conclude that the center (x, y, z) is (-4, 4, -3), and the radius is 4, under the condition that sphere is in standard form.

To present the condition of the circle in standard shape(sphere ), we have to apply summation of the square in terms of including x, y, and z.

The given condition of the sphere is:

[tex]x^2 + y^2 + z^2 + 8x - 8y + 6z + 37 = 0[/tex]

To sum of the square for x, we include the square of half the coefficient of x:

[tex]x^2 + y^2 + z^2 + 8x -8y + 6z + 37 = 0( x^2 = 8x + 16 ) + y^2 +z^2- 8y + 6z+ 37 = 16(x + 4)^2 + y^2 +z ^2 + z^2 - 8y + 6z + 37 - 16 = 16(x + 4)^2 + ( y^2 -8y) + (z^2 + 6z) + 21 = 16 ( x+ 4)^2 + (y^2 - 8y +16) + ( z^2 + 6z +9) = 16( x+ 4)^2+(y -4)^2 +(z=3)^2 =16[/tex]

Hence, the condition is in standard shape:

[tex](x - h)^2 + ( y - k)^2 + ( z - l)^2 = r^2[/tex]

Here,

(h, k, l) = center of the circle,

r = the span.

Comparing the standard frame with the given condition, we are able to see that the center of the sphere is (-4, 4, -3), and the sweep is the square root of 16, which is 4.

Therefore, the center (x, y, z) is (-4, 4, -3), and the sweep is 4.

(a) The argument, arg(ζ) = arctan(imaginary part / real part)

= arctan[b(√3 - a) / (6a(√3 - 1) - b(a√3 + b))]

(b) The cube roots, z^(1/3) = 64^(1/3)[cos((π/6)/3) + isin((π/6)/3)]

= 4[cos(π/18) + isin(π/18)]

(a) To find the argument of the complex number ζ = (-a + ai)(6 + b√3i), we can expand the expression and simplify:

ζ = (-a + ai)(6 + b√3i)

= -6a - ab√3i + 6ai - b√3a + 6a√3 + b√3i²

= (-6a + 6a√3) + (-ab√3 + b√3i) + (6ai - b√3a - b√3)

= 6a(√3 - 1) + b(√3i - a√3 - b)

Now, let's separate the real and imaginary parts:

Real part: 6a(√3 - 1) - b(a√3 + b)

Imaginary part: b(√3 - a)

To find the argument, we need to find the ratio of the imaginary part to the real part:

arg(ζ) = arctan(imaginary part / real part)

= arctan[b(√3 - a) / (6a(√3 - 1) - b(a√3 + b))]

(b) Let's find the cube roots of the complex number z = 32√3 + 32i. We'll use the polar form of a complex number to simplify the calculation.

First, let's find the modulus (magnitude) and argument (angle) of z:

Modulus: |z| = √[(32√3)² + 32²] = √[3072 + 1024] = √4096 = 64

Argument: arg(z) = arctan(imaginary part / real part) = arctan(32 / (32√3)) = arctan(1 / √3) = π/6

Now, let's express z in polar form: z = 64(cos(π/6) + isin(π/6))

To find the cube roots, we can use De Moivre's theorem, which states that raising a complex number in polar form to the power of n will result in its modulus raised to the power of n and its argument multiplied by n:

z^(1/3) = 64^(1/3)[cos((π/6)/3) + isin((π/6)/3)]

= 4[cos(π/18) + isin(π/18)]

Since we want to find all three cube roots, we need to consider all three cube roots of unity, which are 1, e^(2πi/3), and e^(4πi/3):

Root 1: z^(1/3) = 4[cos(π/18) + isin(π/18)]

Root 2: z^(1/3) = 4[cos((π/18) + (2π/3)) + isin((π/18) + (2π/3))]

= 4[cos(7π/18) + isin(7π/18)]

Root 3: z^(1/3) = 4[cos((π/18) + (4π/3)) + isin((π/18) + (4π/3))]

= 4[cos((13π/18) + isin(13π/18)]

Now, let's sketch these cube roots in the complex plane:

Root 1: Located at 4(cos(π/18), sin(π/18))

Root 2: Located at 4(cos(7π/18), sin(7π/18))

Root 3: Located at 4(cos(13π/18), sin(13π/18))

The sketch will show three points on the complex plane representing these cube roots.

The function f(x) = x - 7(x - 1)(x + 5) is continuous for all values of x except -5, 0, and 1. We can express this as (-∞, -5) ∪ (-5, 1) ∪ (1, ∞).

In interval notation, we express intervals using parentheses or brackets to indicate whether the endpoints are included or excluded. To determine where the function f(x) is continuous, we need to identify the values of x that would result in division by zero or undefined expressions.

The function f(x) contains factors of (x - 1) and (x + 5) in the denominator. In order for f(x) to be continuous, these factors cannot equal zero. Therefore, we exclude the values -5 and 1 from the domain of f(x) since they would make the function undefined.

Additionally, since there are no other terms in the function that could result in division by zero, we can conclude that f(x) is continuous for all other values of x. In interval notation, we can express this as (-∞, -5) ∪ (-5, 1) ∪ (1, ∞), indicating that f(x) is continuous for all x except -5, 0, and 1.

The domain of the function f(x) = x + 3 is (-∞, ∞), while the domain of the function g(z) = √(1 - 2z) is (-∞, 1].

For the function f(x) = x + 3, the domain is all real numbers since there are no restrictions or limitations on the values of x. Therefore, the domain of f(x) is (-∞, ∞), which means that x can take any real value.

On the other hand, for the function g(z) = √(1 - 2z), the domain is determined by the square root term. Since the square root of a negative number is not defined in the real number system, we need to find the values of z that make the expression inside the square root non-negative.

The expression inside the square root, 1 - 2z, must be greater than or equal to zero. Solving this inequality, we have 1 - 2z ≥ 0, which gives us z ≤ 1/2.

However, we also need to consider that the function g(z) includes the square root of the expression. To ensure that the square root is defined, we need 1 - 2z to be non-negative, which means z ≤ 1/2.

Therefore, the domain of g(z) is (-∞, 1], indicating that z can take any real value less than or equal to 1/2.

The statement "The Test for Divergence applies to the series Σ 52 n=1" is true. The series 2-1(-1)n-1 is conditionally convergent but not absolutely convergent.

The Test for Divergence is a criterion used to determine if an infinite series converges or diverges. According to the test, if the limit of the n-th term of a series does not equal zero, then the series diverges. In this case, the series Σ 52 n=1 does not have a specific term defined, so the limit of the n-th term cannot be calculated. Hence, the Test for Divergence applies.

The series 2-1(-1)n-1 is an alternating series, where the terms alternate in sign. For an alternating series, the absolute value of the terms should approach zero in order for the series to be absolutely convergent. In this case, as n approaches infinity, the denominator, represented by Vn+1, will grow without bound, making the absolute value of the terms approach infinity. Therefore, the series 2-1(-1)n-1 is not absolutely convergent. However, it can be conditionally convergent, meaning that it converges when both the positive and negative terms are combined.

a. The terms "2/20 EOM" mean that a 2% discount is offered if the invoice is paid within 20 days, and the EOM (End of Month) indicates that the 20-day period starts from the end of the month in which the invoice is issued. Therefore, the final discount date would be 20 days after the end of January.

b. The net payment date is the date by which the invoice must be paid in full without any discount. In this case, the terms state "EOM," which means that the net payment date is 30 days after the end of the month in which the invoice is issued.

c. If the invoice is paid on January 20th, it is within the 20-day discount period. The discount amount would be 2% of $885, which is $17.70. Therefore, the amount to be paid would be the invoice amount minus the discount, which is $885 - $17.70 = $866.70.

Area between the curves is -43/3 square units, which is approximately -14.333 square units. To find the area between the curves y = 5 and y = (x - 1)² + 1 with x ≥ 0, we need to calculate the definite integral of the difference between the upper and lower curves with respect to x.

First, let's find the x-values at which the curves intersect:

For y = 5:

5 = (x - 1)² + 1

4 = (x - 1)²

±2 = x - 1

x = 1 ± 2

The lower curve is y = 5, and the upper curve is y = (x - 1)² + 1.

To find the area between the curves, we integrate the difference between the upper and lower curves: A = ∫[1-2 to 1+2] ((x - 1)² + 1 - 5) dx

Simplifying the integrand:

A = ∫[1-2 to 1+2] (x² - 2x + 1 - 4) dx

A = ∫[1-2 to 1+2] (x² - 2x - 3) dx

Integrating:

A = [x³/3 - x² - 3x] evaluated from 1-2 to 1+2

A = [(1+2)³/3 - (1+2)² - 3(1+2)] - [(1-2)³/3 - (1-2)² - 3(1-2)]

Simplifying further:

A = [(27/3) - 9 - 9] - [(-1/3) - 1 + 3]

A = [9 - 9 - 9] - [-1/3 - 1 + 3]

A = -9 - 7/3

A = -36/3 - 7/3

A triangle with angle A = 57.3°, side a = 10.6, and side c = 13.7, can be solved for the unknown side b using the Law of Sines.

To solve for the unknown side b, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of its opposite angle is constant for all sides and angles of the triangle.

Applying the Law of Sines, we have:

sin(A)/a = sin(B)/b

Substituting the known values, we get:

sin(57.3°)/10.6 = sin(B)/b

Solving for sin(B), we find:

sin(B) = (sin(57.3°) * b) / 10.6

To isolate b, we can rearrange the equation as:

b = (10.6 * sin(B)) / sin(57.3°)

Using a calculator, we can evaluate sin(B) by taking the inverse sine of (a/c) since sin(B) = (a/c) according to the Law of Sines. Once we have the value of sin(B), we can substitute it back into the equation to calculate the value of b.

In summary, by using the Law of Sines, we can solve for the unknown side b by substituting the known values and evaluating the equation. The value of side b can be rounded to the nearest tenth.

First, let's find ∂w/∂u:

Using the chain rule, we have:

∂w/∂u = (∂w/∂x) * (∂x/∂u) + (∂w/∂y) * (∂y/∂u)

∂w/∂x = y² - 1

∂x/∂u = v

∂w/∂y = 2xy + 2

∂y/∂u = (∂w/∂u) * (∂x/∂u) = (∂w/∂u) * v = v*(y² - 1)

Substituting these values, we get:

∂w/∂u = (y² - 1) * v + (2xy + 2) * v*(y² - 1)

Now, let's find ∂w/∂v:

Using the chain rule again, we have:

∂w/∂v = (∂w/∂x) * (∂x/∂v) + (∂w/∂y) * (∂y/∂v)

∂x/∂v = u

∂y/∂v = (∂w/∂v) * (∂x/∂v) = (∂w/∂v) * u = u*(y² - 1)

Substituting these values, we get:

∂w/∂v = (y² - 1) * u + (2xy + 2) * u*(y² - 1)

Finally, we can evaluate ∂w/∂u and ∂w/∂v at the given point (u,v) = (1,-2) by substituting the values of u and v into the respective expressions.

So, ∂w/∂u = (-3y² + 3) and

∂w/∂v = (-3y² + 3).

The complete question is:

"Use an appropriate form of chain rule to find ∂w/∂u and ∂w/∂v at the point (u,v) = (1,-2) if w = x*y² - x + 2y, x = v*u, y = w*x - 2."

The number of people hearing the rumor for the first time will start to decline when the derivative of the function P(t) changes from positive to negative.

To determine when the number of people hearing the rumor for the first time starts to decline, we need to find the critical points of the function P(t). The critical points occur where the derivative of P(t) changes sign.

First, we find the derivative of P(t) with respect to t:

P'(t) = [10(0.19t + 1)ln(0.19t + 1) - 10ln(0.19t + 1)(0.19)] / (0.19t + 1)^2.

To determine the critical points, we set P'(t) equal to zero and solve for t:

[10(0.19t + 1)ln(0.19t + 1) - 10ln(0.19t + 1)(0.19)] / (0.19t + 1)^2 = 0.

Simplifying, we have:

[0.19t + 1]ln(0.19t + 1) - ln(0.19t + 1)(0.19) = 0.

Factoring out ln(0.19t + 1), we get:

ln(0.19t + 1)[0.19t + 1 - 0.19] = 0.

The critical points occur when ln(0.19t + 1) = 0, which means 0.19t + 1 = 1. Taking t = 0 satisfies this equation.

To determine when the number of people hearing the rumor for the first time starts to decline, we need to examine the sign changes of P'(t) around the critical point t = 0. By evaluating the derivative at points near t = 0, we find that P'(t) is positive for t < 0 and negative for t > 0.

(7) the distance RS is approximately 9.695.

(8) the distance PQ is approximately 10.247.

(9) the distance BA is 11.

What is the distance?

Distance refers to the amount of space between two objects or points. It is a measure of the length of the path traveled by an object or a person from one point to another. The most common units of distance are meters, kilometers, feet, miles, and yards.

7. To find the distance RS between points R(5, 6, 12) and S(8, 13, 6), we can use the distance formula in three-dimensional space:

RS = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

  = √((8 - 5)² + (13 - 6)² + (6 - 12)²)

  = √(3² + 7² + (-6)²)

  = √(9 + 49 + 36)

  = √94

  ≈ 9.695

Therefore, the distance RS is approximately 9.695.

8. To find the distance PQ between points P(6, 8, 14) and Q(10, 16, 9), we use the distance formula:

PQ = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

  = √((10 - 6)² + (16 - 8)² + (9 - 14)²)

  = √(4² + 8² + (-5)²)

  = √(16 + 64 + 25)

  = √105

  ≈ 10.247

Therefore, the distance PQ is approximately 10.247.

9. To find the distance BA between points A(9, 13, -4) and B(3, 6, -10), we use the distance formula:

BA = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

  = √((3 - 9)² + (6 - 13)² + (-10 - (-4))²)

  = √((-6)² + (-7)² + (-6)²)

  = √(36 + 49 + 36)

  = √121

  = 11

Therefore, the distance BA is 11.

Hence, (7) the distance RS is approximately 9.695.

(8) the distance PQ is approximately 10.247.

(9) the distance BA is 11.

The function f(x) is defined differently for different values of x.
For x less than 0, f(x) is equal to -x + 1.

For values of x between 0 and 1 (inclusive), f(x) is equal to 1.
For values of x greater than 1, f(x) is equal to -*+2
So overall, the function f(x) is a piecewise function with different definitions for different intervals of x.
Let f(x) be a piecewise function defined as follows:
1. f(x) = -x + 1 for x < 0
2. f(x) = 1 for 0 ≤ x ≤ 1
3. f(x) = -x + 2 for x > 1
This function behaves differently depending on the input value (x). For x values less than 0, the function follows the equation -x + 1. For x values between 0 and 1 inclusive, the function equals 1. And for x values greater than 1, the function follows the equation -x + 2.
