Answer:

u = v - 1

Step-by-step explanation:

I'm guessing the formula you've given me is m = m(v - u), and I'm going to solve it that way. If it's actually different, let me know so I can redo the answer! :)

So, we have the equation m = m(v - u) and we're trying to make u the subject, or isolate it on one side of the equation. Right now, it's being subtracted from v and then multiplied by m. Let's start by dividing both sides of the equation by m so we can stop multiplying (v - u) by m.

m = m(v - u)

m/m = m(v-u)/m

1 = v - u

Now, our equation is pretty simple, but our u is still being subtracted from v, so we should add a u to both sides.

1 = v - u

1 + u = v - u + u

1 + u = v

Now, we're adding 1 to u, so let's go ahead and subtract 1 from both sides.

1 + u = v

1 - 1 + u = v - 1

u = v - 1

And we now we have u as the subject of our formula.

Hopefully that was helpful! :)

Step-by-step explanation:

The prime factorization of the number 21 is:

21 = 3*7

We want to write the prime factorization of 21.

To do so, we just need to divide the number by prime numbers.

The first prime number we can try is 2, if we divide by 2 we get:

21/2 = 10.5

This is not an integer, so 2 is not a factor.

The next one is 3:

21/3 = 7

Now we can rewrite:

21 = 3*7

Where 3 and 7 are prime numbers, so that is the prime factorization.

Answer: A fixed value.

Step-by-step explanation: In Algebra, a constant is a number is by itself, or sometimes a letter such as a, b or c to stand for a fixed number.

Example: in "x + 5 = 9", 5 and 9 are constants.

The score that 75% of the students' exam scores fall below is 0.the 75th percentile is equal to the mean minus 1 standard deviation, or 73 - 5 = 0.

The 75th percentile of a normally distributed set is the point at which 75% of the data falls below that point and 25% of the data falls above that point. In this case, the 75th percentile is equal to the mean minus 1 standard deviation, or 73 - 5 = 0.

Question (b):

The minimum score for an A is -1

The 2.5th percentile of a normally distributed set is the point at which 2.5% of the data falls below that point and 97.5% of the data falls above that point. In this case, the 2.5th percentile is equal to the mean minus 2 standard deviations, or 73 - 2 * 5 = -1.

Here is a more detailed explanation of how to calculate the percentiles in these two questions:

Question (a):

The 75th percentile can be calculated using the following formula:

percentile = mean + (z * standard deviation)

where:

The z-score for the 75th percentile is 0.6745. This can be found using a z-table or by using a calculator.

Plugging in the mean and standard deviation, we get the following:

percentile = 73 + (0.6745 * 5)

percentile = 0

Question (b):

The 2.5th percentile can be calculated using the following formula:

percentile = mean - (z * standard deviation)

where:

The z-score for the 2.5th percentile is -1.96. This can be found using a z-table or by using a calculator.

Plugging in the mean and standard deviation, we get the following:

percentile = 73 - (-1.96 * 5)

percentile = -1

Mean = 62 kilobits per second

Standard deviation = 4 kilobits per second

We use the Z-score formula to solve the given question, where Z = (x-μ)/σ where x = random variable, μ = Mean, σ = Standard deviation We use the Z-score table which is available in the statistics book to find the probability that corresponds to the Z-score.

(a) Find the probability that the file will transfer at a speed of 70 kilobits per second or more?

The probability that the file will transfer at a speed of 70 kilobits per second or more is 0.023.

The probability that the file will transfer at a speed of 70 kilobits per second or more? Z-score formula Z = (x-μ)/σZ = (70-62)/4Z = 2P (Z > 2) = 1- P(Z < 2) = 1- 0.9772 = 0.0228

So, the probability that the file will transfer at a speed of 70 kilobits per second or more is 0.023. (Round to 3 decimal places)

(b) Find Probability that the file will transfer at a speed of less than 58 kilobits per second?

The probability that the file will transfer at a speed of less than 58 kilobits per second is 0.16.

Probability that the file will transfer at a speed of less than 58 kilobits per second: Z-score formula Z = (x-μ)/σZ = (58-62)/4Z = -1P (Z < -1) = 0.1587So, Probability that the file will transfer at a speed of less than 58 kilobits per second is 0.16. (Round to 2 decimal places)

(c) If the file is one megabyte, what is the average time (in seconds) it will take to transfer the file?

The time it will take to transfer one megabyte of file is 0.13 seconds.

Time (in seconds) it will take to transfer one megabyte of file at 8 bits per byte. One megabyte = 8 Megabits (1 byte = 8 bits) Mean = 62 kilobits per second. So, 1 Megabit will take (1/62) seconds, similarly 8 Megabits will take 8*(1/62) = 0.129 seconds. So, the time it will take to transfer one megabyte of the file is 0.13 seconds.

The surfaces described by the given vector equations are:

1.The surface is a hyperbolic paraboloid.

2.The surface is a part of a cylinder with radius 3 and axis parallel to the y-axis.

3.The surface is a plane parallel to the xy-plane and shifted upwards by 1 unit.

4.The surface is a twisted cylinder along the y-axis.

A vector equation of a surface in three-dimensional space is a function that maps a pair of parameters, say u and v, to a three-dimensional point in space (x, y, z) represented as a vector. The vector equation can be written in the form of r(u, v) = <x(u, v), y(u, v), z(u, v)>.

In general, there are different ways to represent the same surface using vector equations. For example, the surface of a sphere of radius r centered at the origin can be represented by the vector equation r(u, v) = <r sin(u) cos(v), r sin(u) sin(v), r cos(u)>, where u is the polar angle (measured from the positive z-axis) and v is the azimuthal angle (measured from the positive x-axis).

Vector equations can be useful in studying the geometry and properties of surfaces, such as determining their tangent planes, normal vectors, curvature, and surface area. They can also be used to parametrize surfaces for numerical calculations and simulations.

An equation that involves a number raised to a variable power is known as exponential equation.

An equation representing the number raised to a variable power is exponential growth or decay equation,

y=abˣ

where 'a' and 'b' are constants.

'x' is the variable exponent,

and 'y' represents the resulting value of the expression.

This equation is involve in exponential growth or decay, such as population growth, compound interest, radioactive decay, and so on.

let us consider a simple example.

Suppose we have a bank account with an initial deposit of $1000 dollars and an annual interest rate of 5%.

Use the exponential equation to find out how much money we will have in our account after 'n' years, where 'n' is a whole number.

y=1000⋅(1+0.05)ⁿ

In this equation, a = 1000 represents the initial deposit,

and b = 1.05 represents the interest rate plus 1.

The variable x is replaced by n, which represents the number of years elapsed since the initial deposit was made.

The resulting value y represents the amount of money in the account after n years.

For example, after 5 years, find out how much money we will have in our account by plugging in n = 5.

y=1000⋅(1+0.05)⁵

 ≈1276.28

Therefore, the exponential equation can be used to model any scenario that involves number raised to a variable power.

Simplifies to:

\(= - 1732.050808 * x^4\)

\(=-4\sqrt[3]{2}\)

12)

\(=3\sqrt[3]6\)

14)

\(=-10x\sqrt[3]{x}\)

Step-by-step explanation:

10)

We have:

\(\sqrt[3]{-128}\)

We want to simplify the cube root. So, let's start picking at the factors.

Notice that -128 is divisible by 64. So:

\(=\sqrt[3]{-1\cdot64\cdot2}\)

Now, notice that 64 is the same as 4³. (-1) is also the same as (-1)³. Therefore:

\(=\sqrt{(-1)^3\cdot(4)^3\cdot2\)

We can now expand our root:

\(=\sqrt[3]{(-1)^3}\cdot\sqrt[3]{(4)^3}\cdot\sqrt[3]{2}\)

The cubes and the cube roots cancel each other out. This leaves us with:

\(=(-1)\cdot(4)\cdot\sqrt[3]2\)

Simplify:

\(=-4\sqrt[3]{2}\)

12)

We have:

\(\sqrt[3]{162}\)

Again, let's see what we can factor out.

If it's unclear what we can factor out, we can guess and check. Since 162 is even, let's divide it by 2. This yields:

\(=\sqrt[3]{2\cdot81}\)

Notice here that 81 is the same as 3⁴. Therefore:

\(=\sqrt[3]{2\cdot3^4}\)

We can separate the 3 from the exponent using the properties of exponents:

\(=\sqrt[3]{2\cdot3\cdot3^3}\)

Expand:

\(=\sqrt[3]{3^3}\cdot\sqrt[3]{2\cdot3}\)

The cube roots and cube will cancel. This leaves us with:

\(=3\cdot\sqrt{2\cdot3}\)

Simplify:

\(=3\sqrt[3]6\)

14)

We have:

\(\sqrt[3]{-1000x^4}\)

Notice here that 1000 is the same as 10³. Also, we can separate an x from the x⁴. Therefore:

\(=\sqrt[3]{-1\cdot (10)^3\cdot x^3\cdot x}\)

Also, (-1) is the same as (-1)³. Thus:

\(=\sqrt[3]{(-1)^3\cdot (10)^3\cdot x^3\cdot x}\)

Expand:

\(=\sqrt[3]{(-1)^3}\cdot\sqrt[3]{(10)^3}\cdot\sqrt[3]{x^3}\cdot\sqrt[3]{x}\)

The cube roots and the cube will cancel. This leaves us with:

\(=-1\cdot10\cdot x\cdot\sqrt[3]{x}\)

Simplify:

\(=-10x\sqrt[3]{x}\)

And we're done!
