find the first partial derivatives of the function. f(x, y, z) = 6x sin(y − z) w=3zexyz

Answers

Answer 1

The partial derivative of w=3zexyz with respect to z is obtained by differentiating exyz with respect to z, treating x and y as constants. This gives ∂w/∂z = 3exyz.

To find the partial derivatives of the given function f(x,y,z), we need to differentiate the function with respect to each variable, treating the other variables as constants.

We have the function:

f(x, y, z) = 6x sin(y − z) w=3zexyz

Let's find the first partial derivative of f with respect to x, y, and z.

Partial derivative of f with respect to x:

f_x = ∂f/∂x

f_x = 6 sin(y - z)

Partial derivative of f with respect to y:

f_y = ∂f/∂y

f_y = 6x cos(y - z)

Partial derivative of f with respect to z:

f_z = ∂f/∂z

f_z = -6x cos(y - z) + 3exyz

The partial derivative of w=3zexyz with respect to z is obtained by differentiating exyz with respect to z, treating x and y as constants. This gives ∂w/∂z = 3exyz.

To warm up, Coach Hadley had his swim team swim twelve 5–meter long laps. It took the team 5 minutes to finish the warm up. How fast did the team swim in centimeters per second?

Answers

The team swam at a speed of 20 centimeters per second during their warm up.

First, let's convert the length of one lap from meters to centimeters:

5 meters = 500 centimeters

So, the team swam 12 laps of 500 centimeters each, for a total distance of:

12 laps × 500 centimeters/lap = 6000 centimeters

Next, let's convert the time from minutes to seconds:

5 minutes = 300 seconds

To find the speed in centimeters per second, we can divide the distance by the time:

speed = distance ÷ time = 6000 centimeters ÷ 300 seconds

simplifying, we get:

speed = 20 centimeters/second

Therefore, the team swam at a speed of 20 centimeters per second during their warm up.

Consider the linear operator T on C2 defined by T(a, b) = (2a + ib, (1-2)a) Compute T (3 i,1 2i)

Answers

The adjoint of the linear operator T on C^2 is T*(x,y) = (2x-2y, ix), and T*(3i,1+2i) = (4i-2, -3).

To compute T*(3 i, 1+2i), we need to first find the adjoint of T, denoted by T*. Recall that T* is the linear operator on C^2 such that for any (x,y) in C^2 and (a,b) in C^2, we have

<T*(x,y),(a,b)> = <(x,y),T(a,b)>

where <,> denotes the inner product on C^2.

To find T*, we need to compute <T*(x,y),(a,b)> for any (x,y) and (a,b) in C^2. We have

<T*(x,y),(a,b)> = <(x,y),T(a,b)>

= <(x,y),(2a+ib,(1-2)a)>

= 2ax + ibx + (1-2)ay

= (2a-2y)x + ibx

Thus, we see that T*(x,y) = (2x-2y, ix) for any (x,y) in C^2.

Now, to compute T*(3i,1+2i), we have

T*(3i,1+2i) = (2(3i)-2(1+2i), i(3i))

= (6i-2-4i, -3)

= (4i-2, -3)

how many arrangements of mathematics are there in which each consonant is adjacent to a vowel?

Answers

There are 1,152 arrangements of "MATHEMATICS" in which each consonant is adjacent to a vowel.

To find the number of arrangements of the word "MATHEMATICS" in which each consonant is adjacent to a vowel, we can treat the consonants (M, T, H, M, T, C, and S) and vowels (A, E, A, I) as separate groups and arrange them in a way that each group of consonants is next to a group of vowels

We have two groups of vowels (A and E, and A and I) and three groups of consonants (MTHM, TC, and S). We can arrange the two vowel groups in 2! = 2 ways, and then arrange the three consonant groups in 3! = 6 ways. Within each group, the letters can be arranged in a total of 4! = 24 ways for the MTHM group, 2! = 2 ways for the TC group, and 1 way for the S group.

Therefore, the total number of arrangements in which each consonant is adjacent to a vowel is:

2! x 6 x 24 x 2 x 1 = 1,152

Matt bought a collection of 1660 stamps. He needs to choose between an album with large pages and an album with small pages to hold his stamps. The number of stamps per page for both album sizes is shown in the table. How many of each type of page will Matt need to hold all 1660 stamps?

Answers

Answer:Martin has 2212 stamps.

Step-by-step explanation:

Given,

Total number of pages = 48,

Out of which first 20 pages each have 35 stamps in 5 rows,

So, the stamps in first 20 pages = 35 × 20 = 700,

Now, the remaining number of pages = 48 - 20 = 28,

Also, each remaining page has 54 stamps,

So, the total stamps contained by remaining pages = 54 × 28 = 1512,

Hence, total stamps = stamps in 20 pages + stamps in 28 pages

= 700 + 1512

= 2212

an observer views the space shuttle from a distance of x = 2 mi from the launch pad.(a) Express the height of the space shuttle as a function of the angle of elevation θ. (b) Express the angle of elevation as a function of the height h of the space shuttle.

Answers

The angle of elevation is a function of the height of the space shuttle given by θ = arctan(h / 2).

Angle of elevation calculation.

(a) To express the height of the space shuttle as a function of the angle of elevation θ, we can use trigonometry. Let h be the height of the space shuttle above the launch pad. Then, we have:

tan(θ) = h / x

Solving for h, we get:

h = x * tan(θ)

Substituting x = 2 mi, we get:

h = 2 * tan(θ) mi

Therefore, the height of the space shuttle is a function of the angle of elevation θ given by h = 2 * tan(θ) mi.

(b) To express the angle of elevation as a function of the height h of the space shuttle, we rearrange the equation we found in part (a) as follows:

tan(θ) = h / x

tan(θ) = h / 2

Taking the inverse tangent of both sides, we get:

θ = arctan(h / 2)

Therefore, the angle of elevation is a function of the height of the space shuttle given by θ = arctan(h / 2).

Use logarithmic differentiation to find the derivative of the function. y = (x^3 + 2)^2(x^4 + 4)^4

Answers

The derivative of the function y = (x^3 + 2)^2(x^4 + 4)^4 using logarithmic differentiation is: y' = 2(x^3 + 2)(x^4 + 4)^3[3x^2(x^4 + 4) + 8x(x^3 + 2)^2]

To use logarithmic differentiation, we take the natural logarithm of both sides of the equation and then differentiate with respect to x using the rules of logarithmic differentiation.

ln(y) = ln[(x^3 + 2)^2(x^4 + 4)^4]

Now, we use the product rule and chain rule to differentiate ln(y):

d/dx [ln(y)] = d/dx [2ln(x^3 + 2) + 4ln(x^4 + 4)]

Using the chain rule, we get:

d/dx [ln(y)] = 2(1/(x^3 + 2))(3x^2) + 4(1/(x^4 + 4))(4x^3)

Simplifying this expression, we get:

d/dx [ln(y)] = 6x^2/(x^3 + 2) + 16x^3/(x^4 + 4)

Finally, we use the fact that d/dx [ln(y)] = y'/y to solve for y':

y' = y(d/dx [ln(y)])

Substituting in the expression for d/dx [ln(y)], we get:

y' = (x^3 + 2)^2(x^4 + 4)^4 [6x^2/(x^3 + 2) + 16x^3/(x^4 + 4)]

To find the earliest time you can serve the pudding, we need to determine the time at which the temperature of the pudding reaches 450.

Using Newton's Law of Cooling, the equation for the temperature of the pudding at time t is given by:

Where:

T(t) is the temperature of the pudding at time t,

T_ambient is the ambient temperature (400),

T_initial is the initial temperature of the pudding (1900),

k is the cooling constant,

To find the earliest time, we set T(t) equal to 450 and solve for t:

Answers

A. Two-way radio A covers 113 square miles.

B. Rounded to the nearest whole number, two-way radio B covers 523 square kilometers.

C. Comparing the areas, we can see that radio B covers the larger area with 523 square kilometers.

D. The coverage area of radio B is approximately 1.33 times larger than the coverage area of radio A.

What is radius?

Radius is a term used in geometry to describe the distance from the center of a circle or sphere to any point on its circumference or surface, respectively. It is usually denoted by the letter "r" and is measured in units of length, such as inches, centimeters, or meters. The radius of a circle is half of its diameter, while the radius of a sphere is one-half of its diameter.

Part A:

The area covered by two-way radio A can be calculated using the formula for the area of a circle:

Area = π x radius²

Radius of radio A = 6 miles

Area = 3.14 x 6²

Area = 113.04 square miles

Rounded to the nearest whole number, two-way radio A covers 113 square miles.

Part B:

The area covered by two-way radio B can also be calculated using the same formula:

Area = π x radius²

Radius of radio B = 12.88 kilometers

Area = 3.14 x (12.88)²

Area = 523.14 square kilometers

Rounded to the nearest whole number, two-way radio B covers 523 square kilometers.

Part C:

To compare the areas covered by the two-way radios, we need to convert the area covered by radio A from square miles to square kilometers, using the conversion factor given:

1 mile = 1.61 kilometers

Therefore, 1 square mile = (1.61)² square kilometers

Area covered by radio A = 113 square miles

Area covered by radio A in square kilometers = 113 x (1.61)²

Area covered by radio A in square kilometers = 290.22 square kilometers

Comparing the areas, we can see that radio B covers the larger area with 523 square kilometers.

Part D:

To determine the scale factor relationship between the radio coverages, we can divide the radius of radio B by the radius of radio A:

Scale factor = radius of radio B / radius of radio A

Scale factor = 12.88 kilometers / 6 miles

Scale factor = 12.88 kilometers / 9.66 kilometers (since 1 mile = 1.61 kilometers)

Scale factor = 1.33

This means that the coverage area of radio B is approximately 1.33 times larger than the coverage area of radio A.

So, t = -b/(2a) = -32/(2*(-16)) = 1.

Therefore, the rocket's greatest height occurs after 1 second of launch. We can find the height by substituting t = 1 into the equation for h(t):

h(1) = -16(1)² + 32(1) + 128 = 144.

Therefore, the rocket's greatest height is 144 feet.

evaluate the line integral, where c is the given curve. c xey dx, c is the arc of the curve x = ey from (1, 0) to (e9, 9)

Answers

The line integral ∫C xey dx on the arc of the curve x = ey from (1, 0) to (e^9, 9) is (1/3)(e^27 - 1).

How to evaluate the line integral on the given curve?

Hi! I'd be happy to help you evaluate the line integral on the given curve. To evaluate the line integral ∫C xey dx, where C is the arc of the curve x = ey from (1, 0) to (e^9, 9), follow these steps:

1. Parameterize the curve: Since x = ey, let y = t, so x = e^t. Thus, the parameterization of the curve is r(t) = (e^t, t), with t ranging from 0 to 9.

2. Compute the derivative of the parameterization: dr/dt = (de^t/dt, dt/dt) = (e^t, 1).

3. Substitute the parameterization into the integrand: xey = (e^t)(e^t) = e^(2t).

4. Compute the dot product of the integrand and dr/dt: (e^(2t)) * (e^t, 1) = e^(3t).

5. Integrate the dot product with respect to t from 0 to 9: ∫(e^(3t)) dt from t = 0 to t = 9.

6. Evaluate the integral: [1/3 * e^(3t)] from t = 0 to t = 9 = [1/3 * e^(27)] - [1/3 * e^0] = (1/3)(e^27 - 1).

So, the line integral ∫C xey dx on the arc of the curve x = ey from (1, 0) to (e^9, 9) is (1/3)(e^27 - 1).

consider all 5 letter "words" made from the letters a through h. (recall, words are just strings of letters,not necessarily actual english words.)(a) how many of these words are there total?

Answers

There are a total of 32768 (8) 5-letter "words" made from the letters a through h when all possible combinations are considered.

Consider all 5-letter "words" made from the letters A through H. There are a total of 8 unique letters, and since repetition is allowed, you can form 8 different possibilities for each of the 5 positions in the word. To calculate the total number of these words, simply multiply the possibilities for each position: 8 * 8 * 8 * 8 * 8 = 32,768. So, there are 32,768 possible 5-letter "words" using the letters A through H.

find the inflection point of the function. (hint: g ' ' ( 0 ) g′′(0) does not exist.) g ( x ) = 9 x | x |

Answers

The inflection point of g(x) = 9|x| is x = 0.

First, let's find the first derivative of g(x):

g'(x) = 9 |x| + 9x * d/dx(|x|)

g'(x) = 9 |x| + 9x * sign(x)

where sign(x) is the sign function, which equals -1 for x < 0, 0 for x = 0, and 1 for x > 0.

Now, let's find the second derivative of g(x):

g''(x) = 9 * d/dx(|x|) + 9 * sign(x) + 9x * d/dx(sign(x))

g''(x) = 0 + 9 * sign(x) + 9x * d/dx(sign(x))

The derivative of the sign function is not defined at x = 0, but we can use the definition of the derivative to find the left and right limits of g''(x) as x approaches 0:

g''(0-) = lim x→0- [g''(x)]

g''(0-) = lim x→0- [9 * (-1) + 9x * (-∞)]

g''(0-) = -∞

g''(0+) = lim x→0+ [g''(x)]

g''(0+) = lim x→0+ [9 * (1) + 9x * (∞)]

g''(0+) = ∞

Since the left and right limits of g''(x) as x approaches 0 are not equal, g''(0) does not exist, and g(x) does not have an inflection point. Instead, the function changes concavity at x = 0, which is a vertical point of inflection.

Answers

Answer:

If the new baseball cards represent 30% of David's special edition baseball card collection, then the original collection represents 70%. Let's represent the total number of cards in David's collection with the variable x. Then we can set up the following equation:

6 = 0.3x

To solve for x, we can divide both sides by 0.3:

x = 6 ÷ 0.3 = 20

Therefore, the total number of cards in David's baseball card collection is 20.

for what values of b are the given vectors orthogonal? (enter your answers as a comma-separated list.) −11, b, 2 , b, b2, b

Answers

The given vectors are:
Vector A = (-11, b, 2)
Vector B = (b, b^2, b)

The values of b for which the given vectors are orthogonal are 0, -3, and 3.

Dot product:


To find the values of b for which the given vectors are orthogonal, we need to use the dot product of the vectors.

To determine if two vectors are orthogonal, their dot product should be equal to zero.

The dot product is calculated as follows:

Dot Product (A, B) = A1 * B1 + A2 * B2 + A3 * B3

Substituting the components of Vector A and Vector B:

(-11 * b) + (b * b^2) + (2 * b) = 0

Now, simplify the equation:

-11b + b^3 + 2b = 0
b^3 - 9b = 0

Factor the equation:

b(b^2 - 9) = 0

Now, we can find the values of b:

b = 0
b^2 - 9 = 0
b^2 = 9
b = ±3

So, the values of b for which the given vectors are orthogonal are 0, -3, and 3.
