Answers

Answer 1

Answer:

56.55km^3

and

6385.03in^3

Step-by-step explanation:

The volume of a sphere is:

Vol = 4/3•pi•r^3

We're going to do 1/2 of that for the hemisphere shape you have in these questions.

Vol = 1/2•4/3•pi•r^3

= 4/6•pi•3^3

= 2/3•pi•27

= 18pi

~= 56.54866776

~= 56.55km^3

One more time for #6.

Vol = 1/2•4/3pi•r^3

= 4/6pi(29/2)^3

= 2/3pi(29/2)^3

not as much stuff cancelling, so we just toss it all into the calculator.

~= 6385.025269033

~= 6385.03in^3

If A is singular, then its transpose is also singular D. If B is the inverse A, then the transpose of B is the Inverse of the transpose of A 20​

Answers

Answer:

The statement that is NOT always true about matrices A, B, and C is:

C. If A is singular, then its transpose is also singular.

Step-by-step explanation:

A matrix A is singular if and only if its determinant is zero. However, the transpose of a matrix does not necessarily have the same determinant as the original matrix. So, it is possible for a matrix A to be singular while its transpose is non-singular. Therefore, statement C is not always true.

evaluate √(3*5^2-c) = -12

Answers

The value of 'c' that satisfies the  Expression √(3 * 5^2 - c) = -12 is c = -69.

The given expression √(3 * 5^2 - c) = -12, we can solve for the value of 'c'. Let's break down the problem step by step.

1. Start with the given expression: √(3 * 5^2 - c) = -12.

2. Square both sides of the equation to eliminate the square root:

  3 * 5^2 - c = (-12)^2.

3. Simplify the equation:

  3 * 25 - c = 144.

4. Multiply 3 by 25:

  75 - c = 144.

5. Subtract 75 from both sides of the equation:

  -c = 144 - 75.

6. Simplify the right side of the equation:

  -c = 69.

7. Multiply both sides of the equation by -1 to solve for 'c':

  c = -69.

Therefore, the value of 'c' that satisfies the given expression √(3 * 5^2 - c) = -12 is c = -69.

It's important to note that when evaluating an equation, we need to ensure that the solution satisfies the original equation. In this case, if we substitute c = -69 back into the original equation, we can verify that both sides of the equation are equal:

√(3 * 5^2 - (-69)) = √(75 + 69) = √144 = 12 = -12 (as given).

Therefore, the solution c = -69 is valid.

1. A farmer buys a certain number of cattle for R240 000. 20 cattle die and he sells the rest at R400 more each than he paid for them. If his profit is R20 000, how much did he pay for each?

Answers

Answer:

R2400

Step-by-step explanation:

This is a math problem. Let’s say the farmer bought x cattle for R240000. So he paid R240000/x for each. After 20 cattle died, he sold the remaining (x-20) cattle at R400 more each than he paid for them.So he sold each for (R240000/x + R400). His total revenue from selling the remaining cattle is (x-20)(R240000/x + R400). Since his profit is R20 000, we can write an equation to solve for x: (x-20)(R240000/x + R400) - R240000 = R20000. Solving this equation, we find that x = 100. So the farmer bought 100 cattle for R240 000, which means he paid R240000/100 = R2400 for each

1. The partial derivative of ∂R/∂R₁ is [tex]R_2^2R_3^2 / (R_1R_2 + R_1R_3 + R_2R_3)^2[/tex]

2.  by symmetry of the problem, ∂R/∂R₂ and ∂R/∂R₃ will be the same expression, but with the roles of the resistances changed. Therefore

∂R/∂R₂ = R₁²R₃² / (R₁R₂ + R₁R₃ + R₂R₃)² and ∂R/∂R₃ = R₁²R₂² / (R₁R₂ + R₁R₃ + R₂R₃)²

How do we find the partial derivative?

The formula for the net resistance R in a parallel circuit is:

R = (R₁R₂R₃) / (R₁R₂ + R₁R₃ + R₂R₃)

The partial derivative ∂R/∂R₁ we can use the quotient rule, which is given by:

(d/dx)[u(x)/v(x)] = [v(x)u'(x) - u(x)v'(x)] / [v(x)]²

u = R₁R₂R₃

v = R₁R₂ + R₁R₃ + R₂R₃,

so u' = R₂R₃

v' = R₂ + R₃ given that the derivative of R₁R₂ and R₁R₃ with respect to R₁ are R₂ and R₃, respectively, and R₂R₃ does not contain R₁, so its derivative is zero.

Applying the quotient rule gives:

∂R/∂R₁ = [R₂R₃(R₁R₂ + R₁R₃ + R₂R₃) - R₁R₂R₃(R₂ + R₃)] / (R₁R₂ + R₁R₃ + R₂R₃)²

= [R₁R₂²R₃ + R₁R₃²R₂ + R₂²R₃² - R₁R₂²R₃ - R₁R₃²R₂] / (R₁R₂ + R₁R₃ + R₂R₃)²

= R₂²R₃² / (R₁R₂ + R₁R₃ + R₂R₃)²

Now, by symmetry of the problem, we can see that ∂R/∂R₂ and ∂R/∂R₃ will be the same expression, but with the roles of the resistances changed. Therefore:

∂R/∂R₂ = R₁²R₃² / (R₁R₂ + R₁R₃ + R₂R₃)²

∂R/∂R₃ = R₁^2R₂^2 / (R₁R₂ + R₁R₃ + R₂R₃)²

The denominators are the same for the partial derivatives with respect to each of the resistances, but the numerators depend on the squares of the other two resistances, not including the one we are differentiating with respect to.

The above answer is based on the full question below;

Suppose that three resistors are in parallel in an electrical circuit. If the resistances are R₁, R₂ and R₃ ohms, respectively, then the net resistance in the circuit equals R =(R₁ R₂ R₃)/(R₁R₂ +R₁R₃ + R₂R₃). Compute the partial differential of ∂R/∂R₁.

Answer:

0.63

Step-by-step explanation:

We have the following information:

The probability of a student being male is 0.45.

The probability of a student having a job off-campus is 0.33.

The probability of a student being male and having a job off-campus is 0.15.

Now, we want to find the probability that a student is either male or has an off-campus job.

To do this, we add the probability of being male (0.45) to the probability of having an off-campus job (0.33). However, we need to be careful not to count the students who are both male and have an off-campus job twice. So, we subtract the probability of being male and having an off-campus job (0.15) once.

By doing this, we account for all the possible cases and get the probability that a student is either male or has an off-campus job.

Calculating the values:

P(Male or Off-campus job) = P(Male) + P(Off-campus job) - P(Male and Off-campus job)

= 0.45 + 0.33 - 0.15

= 0.63

Therefore, the probability that a student chosen at random from the college is male or has an off-campus job is 0.63.

3 King Richard (the Lionheart) was king for 10 years. 4 other kings ruled for 21 years, 16 years, 22 years and 31 years. Work out the range, mean, median and mode for how long these 5 kings ruled.​

Answers

To find the range, we subtract the smallest value from the largest value:

Range = 31 - 10 = 21

To find the mean, we add up all the values and divide by the total number of values:

Mean = (10 + 21 + 16 + 22 + 31) ÷ 5 = 20

To find the median, we need to arrange the values in order from smallest to largest:

10, 16, 21, 22, 31

The median is the middle value when the values are arranged in order. Since there are an odd number of values, the median is the middle value of the sequence, which is 21.

To find the mode, we need to find the value that occurs most frequently in the sequence. In this case, there is no mode because no value occurs more than once in the sequence.

Find the roots of the equation 2x=3sinx+5 using bisection methid

Answers

I'm not pretty sure about your question but hope this can help:

To find the roots of the equation 2x = 3sin(x) + 5 using the bisection method, we need to follow these steps:

Step 1: Define the function

Let's define the function f(x) = 2x - 3sin(x) - 5.

Step 2: Choose an initial interval

We need to choose an interval [a, b] such that f(a) and f(b) have opposite signs. Based on the graph or estimation, we can select an interval that contains the root. Let's choose [a, b] = [0, 2] as an example.

Step 3: Apply the bisection method

Now we can apply the bisection method to find the root within the chosen interval. The steps are as follows:

1. Calculate the midpoint of the interval: c = (a + b) / 2.

2. Evaluate f(c).

3. If f(c) is very close to zero (i.e., |f(c)| < tolerance), then c is the root. Stop the process.

4. If f(a) and f(c) have opposite signs, set b = c. Otherwise, set a = c.

5. Repeat steps 1-4 until you find a root within the desired tolerance.

Step 4: Choose a tolerance

You need to choose a tolerance level, which determines how close to zero the function value needs to be to consider it a root. Let's choose a tolerance of 0.0001 as an example.

Now, let's apply the bisection method step by step:

Step 1: Define the function: f(x) = 2x - 3sin(x) - 5

Step 2: Choose an initial interval: [a, b] = [0, 2]

Step 3: Apply the bisection method:

1. Calculate the midpoint of the interval: c = (0 + 2) / 2 = 1.

2. Evaluate f(c): f(1) = 2(1) - 3sin(1) - 5 ≈ -5.42.

3. Since f(1) is not very close to zero, we proceed to the next step.

4. f(0) = 2(0) - 3sin(0) - 5 = -5, and f(1) = -5.42 have opposite signs.

  Therefore, we update the interval to [a, b] = [0, 1].

5. Repeat steps 1-4.

1. Calculate the midpoint of the interval: c = (0 + 1) / 2 = 0.5.

2. Evaluate f(c): f(0.5) = 2(0.5) - 3sin(0.5) - 5 ≈ -4.11.

3. Since f(0.5) is not very close to zero, we proceed to the next step.

4. f(0) = -5 and f(0.5) ≈ -4.11 have opposite signs.

  Therefore, we update the interval to [a, b] = [0, 0.5].

5. Repeat steps 1-4.

Continue this process until you reach a root within the desired tolerance of 0.0001.

Please note that the bisection method is an iterative process, and it may take several iterations to converge to the root depending on the chosen interval and tolerance level.

The root lies approximately between 1.40625 and 1.4375.

To find the roots of the equation 2x = 3sin(x) + 5 using the bisection method, we need to locate the interval in which the root lies and then iteratively narrow down the interval until we get a root within a desired level of accuracy. The bisection method requires that the function changes sign within the interval we consider.

Let's first rearrange the equation to get it in the form f(x) = 0:

f(x) = 2x - 3sin(x) - 5

Now, we will perform the bisection method:

Step 1: Choose an interval [a, b] where the function changes sign. Let's start with [a, b] = [0, 2] since we can observe a sign change within this interval (f(0) < 0 and f(2) > 0).

Step 2: Calculate the midpoint of the interval: c = (a + b) / 2.

Step 3: Evaluate the function at the midpoint: f(c).

Step 4: If f(c) is close to zero (within the desired level of accuracy), then c is an approximation to the root, and we can stop the iteration.

Step 5: If f(c) has the same sign as f(a), replace a with c; otherwise, replace b with c.

Step 6: Repeat steps 2 to 5 until the desired level of accuracy is achieved.

Let's perform a few iterations to find the root:

Iteration 1:

[a, b] = [0, 2]

c = (0 + 2) / 2 = 1

f(c) ≈ 21 - 3sin(1) - 5 ≈ -5.42 (negative, replace a with c)

Iteration 2:

[a, b] = [1, 2]

c = (1 + 2) / 2 = 1.5

f(c) ≈ 21.5 - 3sin(1.5) - 5 ≈ 1.03 (positive, replace b with c)

Iteration 3:

[a, b] = [1, 1.5]

c = (1 + 1.5) / 2 = 1.25

f(c) ≈ 21.25 - 3sin(1.25) - 5 ≈ -2.07 (negative, replace a with c)

Iteration 4:

[a, b] = [1.25, 1.5]

c = (1.25 + 1.5) / 2 = 1.375

f(c) ≈ 21.375 - 3sin(1.375) - 5 ≈ -0.55 (negative, replace a with c)

Iteration 5:

[a, b] = [1.375, 1.5]

c = (1.375 + 1.5) / 2 = 1.4375

f(c) ≈ 21.4375 - 3sin(1.4375) - 5 ≈ 0.26 (positive, replace b with c)

Iteration 6:

[a, b] = [1.375, 1.4375]

c = (1.375 + 1.4375) / 2 = 1.40625

f(c) ≈ 21.40625 - 3sin(1.40625) - 5 ≈ -0.145 (negative, replace a with c)

Continue the iterations until you achieve the desired level of accuracy. After enough iterations, you'll approximate the root of the equation to a desired precision. In this example, the root lies approximately between 1.40625 and 1.4375.

Write down the time using the 24-hour time format​

Answers

Answer: 19:30 is the current time as per the 24-hour time format

Step-by-step explanation: We know that a day has 24 hours. The time can be shown in two different formats- the 12-hour format and the 24-hour format. 12 hour format ranges only from 1-12 on the hour while 24-hour format varies from 1-24 representing the hour.

      The 24 hour time format is quite simple- marks one number each for one hour. If the Reading says 19:30, it simply means hour 19 of that day. 12-hour time format is different since it makes use of A.M. (Ante Meridiem) and P.M. (Post Meridiem).

Initial Point
(0,-8)
Terminal Point
(9, 12)

Answers

The linear combination of the standard unit vectors i and j for the given initial and terminal points is 9i + 20j.

To find the linear combination of the standard unit vectors i and j, we need to determine the components of the vector that connects the initial point to the terminal point.

Given:

Initial Point: (0, -8)

Terminal Point: (9, 12)

To find the linear combination, we subtract the coordinates of the initial point from the coordinates of the terminal point:

So, Terminal Point - Initial Point

= (9, 12) - (0, -8)

= (9 - 0, 12 - (-8))

= (9, 20)

Therefore, the linear combination of the standard unit vectors i and j for the given initial and terminal points is 9i + 20j.

Answers

The scale factor of the perimeters from figure A to figure B is 1.5. Scale factor is the ratio of any two corresponding lengths in two similar figures.

Here, the two figures are similar, that is why we can find the scale factor by dividing corresponding sides of one figure by the corresponding sides of another figure. We will find the scale factor for the perimeter of figures A and B below:Perimeter of figure A = 12 + 10 + 18 = 40 unitsPerimeter of figure B = 15 + 15 + 15 = 45 unitsTo find the scale factor of the perimeters, we divide the perimeter of figure B by the perimeter of figure

A:Scale factor of the perimeters = (Perimeter of figure B)/(Perimeter of figure A) = 45/40 = 1.125To simplify any fractional answer, we have to convert it to the lowest terms, which is 9/8. The decimal answer 1.125, when rounded to the nearest tenth is 1.1. Therefore, the scale factor of the perimeters from figure A to figure B is 1.5.

Tara decides to keep the car for a few years longer .if she decides to trade her in her car 8 years from now how much will it be worth

Answers

If she decides to trade her in her car 8 years from now then the car will be worth of $8,782.52.

To estimate the future value of Tara's car 8 years from now, we can consider the average depreciation rate of vehicles and assume it applies to her car.

On average, cars tend to depreciate around 15-20% per year.

Let's assume a conservative depreciation rate of 15% per year for Tara's car. We can calculate the future value using the following formula:

Future Value = Current Value× (1 - Depreciation Rate)^Number of Years

Suppose the current value of Tara's car is $20,000.

Plugging in the values, we get:

Future Value = $20,000(1 - 0.15)⁸

Future Value = $20,000(0.85)⁸

Calculating this, we find:

Future Value = $8,782.52

Answers

That equation is unsolvable until you further specify what you want out of it.

Answer:

The correct answer is 7.

Step-by-step explanation:

The sum of 2 and 5 is 7, not 8. Addition is a basic arithmetic operation that combines two numbers to find their total or sum. In this case, when we add 2 and 5 together, we count a total of 7. It's important to carefully perform calculations to ensure accuracy and obtain the correct result.

Many describe the symptoms of HD as having ALS, Parkinsons and Alzheimers simultaneously.Symptoms usually appear between the ages of 30 to 50, and worsen over a 10 to 25 year period. Ultimately, the weakened individual succumbs to pneumonia, heart failure or other complications. Every person who inherits the HD gene will eventually develop the disease. Over time, HD affects the individuals ability to reason, walk and speak. Since the disease does not manifest until a late age, an affected person will often have children already.
