The coordinates of the image of the triangle ABC after the dilation with center (0,0) and a scale factor of 1/2 are:

A' = (1/2 * x₁, 1/2 * y₁)

B' = (1/2 * x₂, 1/2 * y₂)

C' = (1/2 * x₃, 1/2 * y₃)

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

To find the image of triangle ABC after a dilation with center (0,0) and a scale factor of 1/2, we need to multiply the coordinates of each vertex by the scale factor.

Let's suppose that the coordinates of the vertices of the original triangle ABC are:

A = (x₁, y₁)

B = (x₂, y₂)

C = (x₃, y₃)

Then, the coordinates of the image of A, B, and C after the dilation are:

A' = (1/2 * x₁, 1/2 * y₁)

B' = (1/2 * x₂, 1/2 * y₂)

C' = (1/2 * x₃, 1/2 * y₃)

Therefore, the coordinates of the image of the triangle ABC after the dilation with center (0,0) and a scale factor of 1/2 are:

A' = (1/2 * x₁, 1/2 * y₁)

B' = (1/2 * x₂, 1/2 * y₂)

C' = (1/2 * x₃, 1/2 * y₃)

Using the Pythagorean theorem and the law of sines, the correct lengths to the nearest hundredth and the angle measures to the nearest degree are: A) ME = 5; ER = 6, MR ≈ 7.81 m∠E = 90°, m∠M ≈ 50°, m∠R ≈ 40°

The theorem states that the square of the longest side of a right triangle equals the sum of the squares of the lengths of the other two smaller sides of the right triangle.

The points, M(3,2), E(3,−3), and R(9,−3) has been plotted on the graph which shows that angle E  is a right triangle, therefore:

m∠E = 90 degrees.

Find ME and ER:

ME = 5 units

ER = 6 units.

Using the Pythagorean theorem, find MR:

MR = √(ME² + ER²)

MR = √(5² + 6²)

MR = √(25 + 36)

MR = 7.81 units

Using the law of sines, find m∠M:

sin M/ER = sin E/MR

sin M/6 = sin 90/7.81

sin M = (sin 90 × 6)/7.81

sin M = 0.7682

M = sin^(-1)(0.7682)

m∠M ≈ 50°

m∠R = 180 - 50 - 90

m∠R = 40°

Thus, the correct lengths to the nearest hundredth and the angle measures to the nearest degree are:

A) ME = 5; ER = 6, MR ≈ 7.81 m∠E = 90°, m∠M ≈ 50°, m∠R ≈ 40°

The probability that a combined sample from six public swimming areas will reveal the presence of E. coli bacteria is: P(X >= 1) = P(X = 1) + P(X = 2) + P(X = 3) = 0.113 + 0.016 + 0.001 = 0.13 or 13% (rounded to two decimal places).

To find the probability that a combined sample from six public swimming areas will reveal the presence of E. coli bacteria, we can use the binomial distribution formula. Let X be the number of public swimming areas out of six that reveal the presence of E. coli bacteria. Since each swimming area is either contaminated or not contaminated, we have a binomial distribution with n = 6 and p = 0.02 (the probability of finding E. coli bacteria in a public swimming area).

The probability of X = 1 is:

P(X = 1) = (6 choose 1) * (0.02)^1 * (0.98)^5 = 0.113

The probability of X = 2 is:

P(X = 2) = (6 choose 2) * (0.02)^2 * (0.98)^4 = 0.016

The probability of X = 3 is:

P(X = 3) = (6 choose 3) * (0.02)^3 * (0.98)^3 = 0.001

The probability of X = 4, 5, or 6 is negligible since the probability of finding E. coli bacteria in a public swimming area is low.

During the winter season, a family sets up a hot chocolate stand near a local ice skating rink. They sell cups of hot chocolate for $1.50 each and typically sell 50 cups per day.

However, due to changes in weather conditions and customer preferences, the family decides to conduct a market experiment by varying the price of hot chocolate to assess the impact on sales volume. The experiment involves increasing the price to $2.00 per cup and monitoring the resulting sales.

By increasing the price of hot chocolate from $1.50 to $2.00 per cup, the family aims to observe how the change in price affects the demand for their product. The experiment helps them understand the price elasticity of demand, which measures the responsiveness of quantity demanded to changes in price. If the increase in price leads to a significant decrease in sales volume, it suggests that the demand for hot chocolate is elastic, meaning consumers are sensitive to price changes. Conversely, if sales remain relatively stable despite the price increase, it indicates that the demand is inelastic, indicating that consumers are less sensitive to price changes. The family can analyze the results of this experiment to make informed pricing decisions and optimize their profitability during the winter season.

Answer:  shift 2 units right, and 4 units down

==================================================

Explanation:

The x+2 means to shift the point 2 units to the right.

For instance, the point (5,13) moves to (7,13) after adding 2 to the x coordinate.

The y-4 means to shift the point 4 units down. Example: (10,8) moves to (10,4) after subtracting 4 from the y coordinate.

Overall, (x,y)→(x+2,y-4) means "shift 2 units right, and 4 units down"

------------

Example:

Let's apply the rule to the point (1, 7)

(x,y)→(x+2,y-4)

(1,7)→(1+2,7-4)

(1,7)→(3,3)

6(y - 3)(2y + 5)

Step-by-step explanation:

12y^2 - 6y - 90

Factorize

6(2y^2 - y - 15)

Split the term

6(2y^2 - 6y + 5y - 15)

Regroup terms

6((2y^2 - 6y) + (5y - 15))

Factorize

6((2y(y - 3) + 5( y - 3))

Factorize

6(y - 3)(2y + 5)

Answer:

\(6(y-3)(2y+5)\)

Step-by-step explanation:

\(12y^2-6y-90\)

First, factor out the common term of 6:

\(\implies 6(2y^2-y-15)\)

To factor \((2y^2-y-15)\):

Multiply the coefficient of \(y^2\) by the constant:

\(\implies 2 \times -15 = -30\)

Now find factors of -30 that sum to the coefficient of \(-y\), i.e. -1

Factors of 30:  1, 2, 3, 5, 6, 10, 15, 30

So factors of -30 that sum of -1 are:  -6 and 5

Rewrite the middle term of \((2y^2-y-15)\) as \(-6y + 5y\):

\(\implies 2y^2-6y+5y-15\)

Factor each pair of terms:

\(\implies 2y(y-3)+5(y-3)\)

Factor out the constant term:

\(\implies (y-3)(2y+5)\)

Therefore, the final factorization is:

\(\implies 6(y-3)(2y+5)\)

The function that represents the equation in table A is: f(x) = 6x + 15

The function that represents the equation in table B is: g(x) = -2x + 7

The formula to find the linear equation between two coordinates is expressed by the formula:

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

For table A, we are going to use two coordinates namely:

(0, 15) and (1, 21) and we have:

(y - 15)/(x - 0) = (21 - 15)/(1 - 0)

(y - 15)/x = 6

y - 15 = 6x

y = 6x + 15

For table B, we are going to use two coordinates namely:

(0, 7) and (1, 5)

Thus:

(y - 7)/(x - 0) = (5 - 7)/(1 - 0)

y - 7 = -2x

Answer:

you have it correct sir

Step-by-step explanation:

The given functions ψ = 2xy and φ = x^2 - y^2 satisfy the conditions for continuity and irrotational flow.

To show continuity, we need to verify that the partial derivatives of ψ and φ with respect to x and y are equal. Let's calculate these partial derivatives:

∂ψ/∂x = 2y

∂ψ/∂y = 2x

∂φ/∂x = 2x

∂φ/∂y = -2y

From the above calculations, we can see that the partial derivatives of ψ and φ with respect to x and y are equal. Therefore, the condition for continuity, which requires the equality of partial derivatives, is satisfied.

To show irrotational flow, we need to verify that the curl of the velocity vector is zero. The velocity vector can be obtained from the stream function ψ and velocity potential φ as follows:

V = ∇φ x ∇ψ

Taking the curl of V:

∇ x V = ∇ x (∇φ x ∇ψ)

Using vector calculus identities and simplifying the expression, we find:

∇ x V = 0

Since the curl of the velocity vector is zero, the condition for irrotational flow is satisfied.

Therefore, based on the calculations and verifications, we can conclude that the given functions ψ = 2xy and φ = x^2 - y^2 satisfy the conditions for continuity and irrotational flow.

The probability that the sample mean will be within plus minus 2 of the population mean if the sample size is n = 100 between z-scores of 0 and 2.5 using a z-table.

The standard deviation of the sample distribution, commonly known as the standard error, can be computed using the formula given that the population mean is 100 and the standard deviation is 16:

Standard Error = Standard Deviation / sqrt(sample size)

Let's determine the likelihoods for sample sizes of n = 100 and n = 400:

For n = 100:

Standard Error = 16 / sqrt(100) = 16 / 10 = 1.6

We can determine the z-scores for the upper and lower boundaries to establish the likelihood that the sample mean will be within plus or minus 2 of the population mean:

Lower Bound z-score = (Sample Mean - Population Mean) / Standard Error

Lower Bound z-score = (100 - 100) / 1.6

Lower Bound z-score = 0

Upper Bound z-score = (Sample Mean - Population Mean) / Standard Error

Upper Bound z-score = (104 - 100) / 1.6

Upper Bound z-score = 4 / 1.6

Upper Bound z-score = 2.5

We can calculate the region under the normal distribution curve between z-scores of 0 and 2.5 using a z-table or statistical software. This shows the likelihood that the sample mean will be within +/- 2 standard deviations of the population mean.

For n = 400:

Standard Error = 16/√400

Standard Error = 16/20

Standard Error = 0.8

We determine the z-scores by following the same procedure as above:

Lower Bound z-score = (Sample Mean - Population Mean) / Standard Error

Lower Bound z-score = (100 - 100) / 0.8

Lower Bound z-score = 0

Upper Bound z-score = (Sample Mean - Population Mean) / Standard Error

Upper Bound z-score = (104 - 100) / 0.8

Upper Bound z-score = 4 / 0.8

Upper Bound z-score = 5

Once more, we may determine the region under the normal distribution curve between z-scores of 0 and 5 using a z-table or statistical software.

A larger sample size, like n = 400, has the benefit of a lower standard error. The sampling distribution of the sample mean will be more constrained and more closely resemble the population mean if the standard error is less.

As a result, there is a larger likelihood that the sample mean will be within +/- 2 of the population mean. In other words, the estimate of the population mean gets more accurate and dependable as the sample size grows.

A sample size of at least 960,400 similarity scores to ensure reasonable accuracy with greater-than-95% probability. Since we have 35,994,000 non-match similarity scores, this sample size is easily achievable.

Assuming that the similarity scores are uniformly distributed, we can use the binomial distribution to calculate the probability of obtaining a certain number of correct matches. Let's assume that we want to achieve a margin of error of 1% and a confidence level of 95%. This means that we want to be 95% confident that the true proportion of matches is within 1% of our estimate.

Using the formula for the sample size of a binomial distribution, n = (Z^2 * p * (1-p)) / (E^2), where Z is the critical value from the standard normal distribution (1.96 for a confidence level of 95%), p is the expected proportion of matches (unknown), and E is the margin of error (0.01), we can solve for the sample size:

n = (1.96^2 * 0.5 * 0.5) / 0.01^2 ≈ 960,400

Therefore, we would need a sample size of at least 960,400 similarity scores to ensure reasonable accuracy with greater-than-95% probability. Since we have 35,994,000 non-match similarity scores, this sample size is easily achievable.
