Note that in order to map A onto B, Kyle would have to dilate the given figure by a scale factor or 3.
What is a scale factor?The scale factor is a metric for figures with similar appearances but differing scales or measurements. Assume two circles appear similar but have different radii. The scale factor specifies how much larger or smaller a figure is than the original figure.
The original point of figure A which has 4 points are
(0,02)
(-1, 2)
(0, 1)
(1, 2)
Multiply all th e points by 3, and you get,
(0,02) x 3 = (0, -6) =
(-1, 2) x 3 = (-3, 6)
(0, 1) x 3 = (0, 3)
(1, 2) x3 = (3, 6)

By using TABLE 1, calculate if Mr Mbhalati is correct. 2 Mr Mbhalati has Mr Prepaid account with one of the banks in South Africa. He uses the account to pay water bills. TABLE 2 shows deposit fees applicable on his account in 2023. TABLE 2: Mr Prepaid ACCOUNT COSTS AT ABA BANK FOR DEPOSITS TRANSACTION Notes and coin deposit COSTS RS0 - R2. 25 per R100 (for notes) - R5 per R100 (for coins) or part thereof the amount deposited. [Adapted by examiner from information supplied by various banks Use the information from TABLE 2 to answer the questions that follow. 3 20231
1. 2. 1 Determine The Minimum Amount One Will Pay When Making A Deposit Of Notes And Coins (2)
1. 2. 2 Mbhalati Says He Will Be Charged R180 When Making A Deposit Of Notes To the Value Of R 1 500 and R500 In Coins. Show By Means Of Calculations Whether His Statement Is Valid (5)
1. 2. 3 Mr Mbhalati Deposited R 1 500 An Amount From Sale Of Goods That Were Sold At A ValueAddedTax(VAT) Inclusive Price
Calculate 15% Vat Of amount On Goods Sold(4)
1. 2. 4 Name At Least ONE Method Me Mbhalati Can Use To Send Money To A Person Who Does Not Have A Bank Account(2)
The Deposit Fees 15% VAT amount on goods sold at a VAT-inclusive price of R1,500 would be approximately R195.65.
To answer the questions using the provided information, we'll refer to TABLE 2 for the deposit fees.1.2.1 The minimum amount one will pay when making a deposit of notes and coins:
Notes: R2.25 per R100 or part thereof
Coins: R5 per R100 or part thereof
Therefore, the minimum amount one will pay depends on the value of the deposit. For notes, it will be R2.25 per R100 or part thereof, and for coins, it will be R5 per R100 or part thereof.
1.2.2 To determine if Mr Mbhalati's statement is valid, let's calculate the deposit fees for his deposit of notes and coins.
Deposit of notes:
Deposit amount: R1,500
Deposit fee for notes: R2.25 per R100 or part thereof
Calculation:
Deposit fee = (Deposit amount / 100) * Deposit fee per R100
= (1500 / 100) * 2.25
= 33.75
Deposit of coins:
Deposit amount: R500
Deposit fee for coins: R5 per R100 or part thereof
Calculation:
Deposit fee = (Deposit amount / 100) * Deposit fee per R100
= (500 / 100) * 5
= 25
Total deposit fee = Deposit fee for notes + Deposit fee for coins
= 33.75 + 25
= 58.75
Therefore, Mr Mbhalati's statement is not valid. The total deposit fee for his deposit of notes to the value of R1,500 and R500 in coins would be R58.75, not R180.
1.2.3 To calculate the 15% VAT on the amount of goods sold at a VAT-inclusive price:
Amount from the sale of goods: R1,500
Calculation:
VAT amount = (Amount from the sale of goods / (100 + VAT rate)) * VAT rate
= (1500 / (100 + 15)) * 15
= (1500 / 115) * 15
≈ 195.65
Therefore, the Deposit Fees 15% VAT amount on goods sold at a VAT-inclusive price of R1,500 would be approximately R195.65.
1.2.4 One method Mr Mbhalati can use to send money to a person who does not have a bank account is by using a money transfer service like Western Union or MoneyGram. These services allow individuals to send money to recipients who can collect it in cash from designated locations, even if they don't have a bank account.

(a) The value of Zdz for the circle [z] = 2 traversed once counterclockwise is 0. (b) The value of Zdz for the circle [z] = 2 traversed once clockwise is 0. (c) The value of Zdz for the circle [z] = 2 traversed three times clockwise is 0.
The integral of Zdz around a closed curve in the complex plane is known as the contour integral. In this case, the circle [z] = 2 is a closed curve, and since it is traversed an equal number of times in both the clockwise and counterclockwise directions, the value of Zdz is 0. This is a consequence of Cauchy's theorem, which states that if a function is analytic within and on a simple closed curve, then the integral of the function around the curve is 0. Since the function Z is analytic within and on the circle [z] = 2, the integral of Zdz around the circle is 0.

two planes, which are 1780 miles apart, fly toward each other. their speeds differ by 40mph. if they pass each other in 2 hours, what is the speed of each?
The speed of the planes are:
870 mph 910 mph.Two planes fly towards each other, and they are 1780 miles apart. If they pass each other in 2 hours, and their speeds differ by 40mph, we must find out the speed of each.
For the speed of each plane, we can use the formula:
D = R × T
Where, D = Distance, R = rate and T= time
Here, D = 1780 miles
T = 2 hours
Let's assume that the speed of one plane is 'x' mph. Then the speed of the second plane would be 'x + 40' mph.
Both planes are flying toward each other, so we must add up their speeds to find the combined speed of both planes.
Rate or Speed of Plane 1 = x mph
Rate or Speed of Plane 2 = x + 40 mph
Combined Speed = (x + x + 40) mph ⇒ (2x + 40) mph
According to the question, the two planes covered a distance of 1780 miles. We can write it down as:
2x + 40 = 1780
2x = 1780 - 40
2x = 1740
x = 870
The speed of one plane is 870 mph.
Therefore, the speed of the second plane would be:
x + 40 = 870 + 40 = 910 mph
Hence, the speed of each plane is 870 mph and 910 mph, respectively.

What is the probability that a person who tests positive actually has the disease? 5) A)0. 719 B)0. 582 C)0. 032 D)0. 914 E)0. 418
The probability that a person who tests positive has the disease is 0.032
we can use Bayes' theorem. Let's denote the following events
A: A person has the disease
B: The person tests positive
We are given the following probabilities
P(A) = 2% = 0.02 (probability of a person having the disease)
P(B|A) = 91.4% = 0.914 (probability of testing positive given that the person has the disease)
P(B|not A) = 4.2% = 0.042 (probability of testing positive given that the person does not have the disease)
We want to find P(A|B), the probability that a person has the disease given that they test positive.
By Bayes' theorem, we have
P(A|B) = (P(B|A) × P(A)) / P(B)
P(B), the probability of testing positive, we can use the law of total probability
P(B) = P(B|A) × P(A) + P(B|not A) × P(not A)
P(not A) represents the complement of having the disease, which is 1 - P(A).
Substituting the values
P(B) = (0.914 × 0.02) + (0.042 × (1 - 0.02))
P(B) = 0.01828 + 0.04116
P(B) = 0.05944
Now, let's calculate P(A|B)
P(A|B) = (0.914 × 0.02) / 0.05944
P(A|B) = 0.01828 / 0.05944

The inverse of the matrix M does not exist. To find the inverse of a matrix, we can use the formula: M^(-1) = 1/|M| * adj(M)
where |M| is the determinant of M and adj(M) is the adjoint of M. The adjoint of a matrix is the transpose of its cofactor matrix.
In this case, the determinant of M is 0. This means that M is not invertible and therefore M^(-1) does not exist.
Here is why the determinant of M is 0. The determinant of a 3x3 matrix can be computed using the following formula:
|M| = a11 * a22 * a33 + a12 * a23 * a31 + a13 * a21 * a32 - a13 * a22 * a31 - a12 * a21 * a33 - a11 * a23 * a32
where a11, a12, a13, a21, a22, a23, a31, a32, and a33 are the elements of the matrix M. In this case, the elements of M are 1, 12, 2, 210, 0, and 22. Substituting these values into the formula for the determinant, we get:
```
|M| = 1 * 22 * 22 + 12 * 0 * 2 - 2 * 12 * 21 = 0
```
Therefore, the determinant of M is 0 and M is not invertible.

The type of queuing model applying for the arrival rate of customers follows a poisson distribution is "M/M/2".
Explain the term queuing model?When consumers arrive at random to obtain a service and the service time is also a random variable, a queuing model is an appropriate model to represent the situation.
Multiple service counters and connected queues make up a queuing system. Each service center has a set number of servers (c) that operate concurrently; as a customer moves up the line, they are given the first server that becomes available.M/M models are the most basic and widely used models in queueing theory. Although the Ms stand for "Markov," they actually stand for "exponential". The arrival is indeed a Poisson process because the intervals between arrivals have an exponential distribution.For the stated question-

Find the particular antiderivative of the following derivative that satisfies the given condition. C''(x)=4x2-3x ; C(0)=2000
The particular antiderivative that satisfies the given condition is: C(x) = (4/9)x^4 - (9/8)x^3 + K1x + 2000
To find the particular antiderivative (or integral) of the given derivative \(C''(x) = 4x^2 - 3x\) that satisfies the condition C(0) = 2000, we need to integrate the given function twice.
First, we integrate C''(x) to find C'(x):
\(C'(x) = ∫ (4x^2 - 3x) dx\)
To find the antiderivative of \(4x^2\), we use the power rule for integration: the power of x increases by 1 and is divided by the new power. Similarly, the antiderivative of -3x is \(-(3/2)x^2\).
\(C'(x) = ∫ (4x^2 - 3x) dx = (4/3)x^3 - (3/2)x^2 + K1\)
Here, K1 is the constant of integration. Next, we integrate C'(x) to find C(x):
\(C(x) = ∫ (C'(x)) dx = ∫ ((4/3)x^3 - (3/2)x^2 + K1) dx\)
To find the antiderivative of \((4/3)x^3\), we again use the power rule for integration. Similarly, the antiderivative of \(-(3/2)x^2\) is \(-(3/2)(1/3)x^3\).
The constant of integration K1 will also be integrated with respect to x, resulting in another constant of integration, K2.
\(C(x) = (1/3)(4/3)x^4 - (1/2)(3/2)x^3 + K1x + K2\)
Simplifying further, we have:
\(C(x) = (4/9)x^4 - (9/8)x^3 + K1x + K2\)
Now, we can apply the initial condition C(0) = 2000 to find the particular solution for K2:
\(C(0) = (4/9)(0)^4 - (9/8)(0)^3 + K1(0) + K2 = 2000\)
Since all the terms involving x become zero when x = 0, we have:
K2 = 2000
Therefore, the particular antiderivative that satisfies the given condition is: \(C(x) = (4/9)x^4 - (9/8)x^3 + K1x + 2000\)

Answer: SR = 42
Step-by-step explanation:
8x-6 = 36 + x
subtract x
8x - x - 6 = 36 + x - x
(Note +x -x = 0, same goes to any number or variable.)
7x - 6 = 36
add 6
7x - 6 + 6 = 36 + 6
7x = 42
7x/7 = 42/7
x = 6
So far we found x, so now we would put x in SR which is 8x - 6
SR = 8x - 6
SR = 8(6) - 6
SR = 48 - 6
SR = 42.
Therefore SR is 42.
urn i contains two red chips and four white chips: urn ii, three red and one white. a chip is drawn at random from urn i and transferred to urn ii. then a chip is drawn from urn ii. what is the probability that the chip drawn from urn ii is red?
The probability that the chip drawn from urn II is red is 4/15. Let's call the event that the chip drawn from urn I and transferred to urn II is red "R1", and the event that the chip drawn from urn II is red "R2".
The probability of event R1 is 2/6 = 1/3.
Given that event R1 has occurred, the number of red chips in urn II becomes 4, and the number of total chips becomes 4+1=5. The probability of event R2 is 4/5 = 4/5.
The probability of both events occurring is (1/3) * (4/5) = 4/15.

The unknown angles in the triangles are as follows:
interior angle = 84.5 degrees
Exterior angle = 124.5 degrees
How to find the side of a triangle?The triangle exterior angles theorem can be used to find the variable in the triangle.
Therefore, the exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.
Hence, let's find the variable x in the triangle.
37 + 3x + 47 = 5x + 62
87 + 3x = 5x + 62
5x - 3x = 87 - 62
2x = 25
divide both sides by 2
x = 25 / 2
x = 12.5
Therefore, let's find the angles
3x + 47 = 3(12.5) + 47 = 84.5 degrees
5x + 62 = 5(12.5) + 62 = 124.5 degrees

Assume that adults have IQ scores that are normally distributed
with a mean μ=100 and a standard deviation σ=20. Find the
probability that a randomly selected adult has an
IQ between 89 and 110.
This probability can be found by subtracting the area to the left of -0.55 from the area to the left of 0.50.
The probability that a randomly selected adult has an IQ between 89 and 110, given a normal distribution with a mean of 100 and a standard deviation of 20, can be determined by calculating the area under the normal curve between these two IQ values.
In order to find this probability, we need to standardize the IQ values using z-scores. The formula for calculating the z-score is:
z = (x - μ) / σ
where x is the IQ value, μ is the mean, and σ is the standard deviation.
For the lower IQ value of 89, the z-score is (89 - 100) / 20 = -0.55, and for the higher IQ value of 110, the z-score is (110 - 100) / 20 = 0.50.
Using a standard normal distribution table or a calculator that provides the area under the curve, we can find the probabilities associated with these z-scores.
The probability of a randomly selected adult having an IQ between 89 and 110 is equal to the area under the curve between the z-scores of -0.55 and 0.50. This probability can be found by subtracting the area to the left of -0.55 from the area to the left of 0.50.
The first paragraph summarizes the problem and states that the task is to find the probability that a randomly selected adult has an IQ between 89 and 110.
The second paragraph explains the steps involved in calculating this probability, including standardizing the IQ values using z-scores and finding the corresponding probabilities using a standard normal distribution table or calculator.
The final step is to subtract the area to the left of the lower z-score from the area to the left of the higher z-score to obtain the probability.
