The formula for m in terms of r and b is m = r/5 + 7b/5.

Given the equation in the question;

r = 5m - 7b​

To make m the subject of the formula, we need to isolate m on one side of the equation.

r = 5m - 7b

First, we can start by adding 7b to both sides of the equation:

r + 7b = 5m - 7b + 7b

Simplifying the right-hand side:

r + 7b = 5m

Then, we can divide both sides of the equation by 5 to isolate m:

(r + 7b) / 5 = (5m) / 5

Simplifying:

(r + 7b) / 5 = m

m = r/5 + 7b/5

Therefore, the formula for m is m = r/5 + 7b/5.

The root of the equation \(\(f(x) = x^3 - 3x - 1\)\) between -1 and 1, after the second iteration of the False Position method, is approximately -1.

The False Position method involves finding the x-value that corresponds to the x-intercept of the line passing through \(\((a, f(a))\)\) and \(\((b, f(b))\),\)where (a) and (b) are the endpoints of the interval.

Let's begin the iterations:

Iteration 1:

\(\(a = -1\), \(f(a) = (-1)^3 - 3(-1) - 1 = -3\)\)

\(\(b = 1\), \(f(b) = (1)^3 - 3(1) - 1 = -3\)\)

The line passing through (-1, -3) and (1, -3) is (y = -3). The x-intercept of this line is at (x = 0).

Therefore, the new interval becomes [0, 1] since the sign of f(x) changes between\(\(x = -1\) and \(x = 0\).\)

Iteration 2:

\(\(a = 0\), \(f(a) = (0)^3 - 3(0) - 1 = -1\)\)

\(\(b = 1\), \(f(b) = (1)^3 - 3(1) - 1 = -2\)\)

The line passing through\(\((0, -1)\) and \((1, -2)\) is \(y = -x - 1\)\). The x-intercept of this line is at (x = -1).

After the second iteration, the new interval becomes [-1, 1] since the sign of f(x) changes between (x = 0) and (x = -1).

Therefore, the root of the equation \(\(f(x) = x^3 - 3x - 1\)\) between -1 and 1, after the second iteration of the False Position method, is approximately -1.

Step-by-step explanation:

M=u-2056

U=m+2056

U=22010+2056=24066

Answer: See explanation

Step-by-step explanation:

For questions 1 - 4, it's asking you to plug in numbers into the original functions.

1. f(-2): You would plug -2 into f(x) = 2x^2 - 3x, getting

2(-2)^2 - 3(-2)

2(4) - (-6)

8 + 6 = 14

f(-2) = 14

2. f(x) - g(x): You're basically just subtracting the two functions

(2x^2 - 3x) - (2 - 5x)

2x^2 - 3x - 2 + 5x

Combine like terms

2x^2 + 2x - 2

3. You're multiplying them so (2x^2 - 3x)(2 - 5x)

4. f(g(x)): It's like f(-2), but instead of -2, you plug in the function of g(x)

So in 2x^2 - 3x, x would equal 2 - 5x:

2(2 - 5x)^2 - 3(2 - 5x)

And then simplify that.

For questions 5 - 6, it's asking for shifting from the parent function. Parent function is always f(x) or g(x) or whatever variable it is.

5. f(x - 8) + 9: The 9 is the y value shift, meaning the parent function is shifted up 9 units. For -8, think of what x needs to be for (x - 8) to be 0. If that number is positive, function shifts right; if negative, shift left. In this case, x needs to be 8 in order for (x - 8) to be 0. Therefore, f(x) is shifted right 8 units.

6. -3f(x) - 2: From the previous question, we now know that -2 means f(x) is shifted down 2 units. When you have 3f(x), you're multiplying the entire function by 3, so it's called a vertical stretch of 3. The negative means it's reflected over the x-axis since the y value is the opposite of what it used to be.

The equivalent to √-80 is 4√5

What is square root of imaginary ?

The square root of minus one √(−1) is the "unit" Imaginary Number, the equivalent of 1 for Real Numbers. In mathematics the symbol for √(−1) is i for imaginary.

The given expression is √-80

The factors of 80 is

⇒√-(2 * 2* 2 * 2 * 5)

Take 4 out of the root

⇒ 4√-5

Since value inside the root is not to be negative. If it is then it means it is imaginary root or i.

So, the answer will be

Answer: 12/25

Step-by-step explanation:  3/25 × 4 is equaled to 3/25 × 4/1.

So first  we take 3 and 4 and multiply them to make 12.  

Then we take 25 and multiply it by 1 which would equal to 25.

Now we have 12/25 which cannot be simplified.

Relations and Functions

A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.

From the options presented below, we'll mark as functions only those who don't have relations between one element in the input set with more than one element in the output set.

In the first relation, every input element is related to only one output element. The same occurs in the second relation.

Note that in the third relation, the input element -5 is related to 4 and also to -4. Element -3 is also related to two different elements. This is not a function.

The fourth relation has the input element 1 related to two different output elements in the pairs (1,0) and (1,2). Thus, this is not a function either.

The fifth relation is a function. No input element is related to more than one output element.

Answer:

\(E=2.15\times 10^{-4}\ J\)

Step-by-step explanation:

Given that,

The capacitance of the capacitor, \(C=2.2\times 10^{-6}\ F\)

Voltage of the power supply, V = 14 V

We need to find the energy stored in the capacitor.

The formula for the stored energy in the capacitor is given by :

\(E=\dfrac{1}{2}CV^2\)

Put all the values,

\(E=\dfrac{1}{2}\times 2.2\times 10^{-6}\times 14^2\\\\E=2.15\times 10^{-4}\ J\)

So, \(2.15\times 10^{-4}\ J\) of energy is stored in the capacitor.

The probability that an arriving student will find at least one other student waiting in line is approximately 0.167.

To solve this problem, we'll use the M/M/1 queueing model with Poisson arrivals and exponential service times. Let's calculate the required values: (a) Percentage of time Judy is idle: The utilization of the system (ρ) is the ratio of the average service time to the average interarrival time. In this case, the average service time is 10 minutes, and the average interarrival time is 12 minutes. Utilization (ρ) = Average service time / Average interarrival time = 10 / 12 = 5/6 ≈ 0.8333

The percentage of time Judy is idle is given by (1 - ρ) multiplied by 100: Idle percentage = (1 - 0.8333) * 100 ≈ 16.67%. Therefore, Judy is idle approximately 16.67% of the time. (b) Average waiting time for a student:

The average waiting time in a queue (Wq) can be calculated using Little's Law: Wq = Lq / λ, where Lq is the average number of customers in the queue and λ is the arrival rate. In this case, λ (arrival rate) = 1 customer per 12 minutes, and Lq can be calculated using the queuing formula: Lq = ρ^2 / (1 - ρ). Plugging in the values: Lq = (5/6)^2 / (1 - 5/6) = 25/6 ≈ 4.17 customers Wq = Lq / λ = 4.17 / (1/12) = 50 minutes. Therefore, on average, a student spends approximately 50 minutes waiting in line.

(c) Average length of the line: The average number of customers in the system (L) can be calculated using Little's Law: L = λ * W, where W is the average time a customer spends in the system. In this case, λ (arrival rate) = 1 customer per 12 minutes, and W can be calculated as W = Wq + 1/μ, where μ is the service rate (1/10 customers per minute). Plugging in the values: W = 50 + 1/ (1/10) = 50 + 10 = 60 minutes. L = λ * W = (1/12) * 60 = 5 customers. Therefore, on average, the line consists of approximately 5 customers.

(d) Probability of finding at least one student waiting in line: The probability that an arriving student finds at least one other student waiting in line is equal to the probability that the system is not empty. The probability that the system is not empty (P0) can be calculated using the formula: P0 = 1 - ρ, where ρ is the utilization. Plugging in the values:

P0 = 1 - 0.8333 ≈ 0.1667. Therefore, the probability that an arriving student will find at least one other student waiting in line is approximately 0.167.
