y=2x+7. In order to create an equation that is parallel to the old equation, Julie must make sure that her new equation has the same slope as the old equation. The slope of the old equation is 2, so Julie's new equation should also have a slope of 2. Additionally, she must make sure that the y-intercept of her new equation is the same as the given data point, which is (6, 7). Therefore, the new equation should be in the form y = 2x + b, where b is the y-intercept. Plugging in the values from the given data point, we get y = 2x + 7. This equation is parallel to the old equation and passes through the given data point, so it is the correct answer.

Answer:

The answer to the question is that the new equation that is parallel to the old equation and passes through the point (6, 7) is y = 2x - 5.

Step-by-step explanation:

To create an equation that is parallel to the old equation, you need to use the same slope. This means that your new equation should be y = 2x + b, where b is a constant. Since the point (6, 7) is on the new equation,  you can plug those values into the equation to find b.

Answer:

The rate of change in this situation is 6 degrees per hour.

Step-by-step explanation:

The rate of change in this situation is -6 degrees per hour. To find this, we need to divide the change in temperature by the amount of time over which the change occurs. In this case, the temperature falls from 43 degrees to 43-6=<<43-6=37>>37 degrees, so the change in temperature is 43-37=<<43-37=6>>6 degrees. Since the temperature falls over the course of one night, the rate of change is 6 degrees / 1 night = -6 degrees per hour.

The probability that no letters are repeated is 0.0015, rounded to the nearest thousandth.

The probability that no letters are repeated is calculated using the formula P = n! / (r^n * (n-r)!)

, where n is the total number of letters and r is the number of each letter.

The numbers here are n = 7 and r = 1.

This means the probability of no letters being repeated is 7! / (1^7 * 6!) = 0.0015.

This can be rounded to the nearest thousandth, giving the answer of 0.0015.

Please find attached the drawing of the image of the segment following a dilation by a scale factor of 2 with the center at the origin, created with MS Word.

A dilation transformation is one in which the size of the object is increased (or decreases) proportionately by a factor known as the scale factor of dilation.

The center of dilation is the origin, which is the point (0, 0)

The coordinates of points on the line segment are; (5, 5) and (0, 0)

Therefore, the line segment to be dilated passes through the center of dilation

The image of the segment to be dilated also will pass through the center of dilation, which is the origin or the point (0, 0)

The dilation of the segment by a scale factor of 2 has a point at the origin (0, 0), the second point is therefor at the point (2× 5,  2 × 5) = (10, 10)

The coordinates of the image of the segment following a dilation are therefore; (0, 0), and (10, 10)

Answer:

This answer assumes that the function is A(x) = 100x − 2x^2.  The function as written is A(x) = 100x - (4 or 4x)

The domain is 0 - 50 feet.

Step-by-step explanation:

The area function is a polynomial with a vertex (hghest area possible) at (25,1250).  This is telling us that for a side length of 25 feet, the area is at a maximum of 1250 ft^2.  This is actually not totally correct.  We only need 3 sides of fencing since the school wall will make up the fourth.  The given equation does not seem to allow for this caveat, since it uses 100 feet for all four sides.

Given the equation, the domain for the function A(x) is positive for all values between 0 and 50 feet.  The domain is 0 - 50 feet.

4. The constant of proportionality is  is 3 ounces of almond per ounces of dark chocolate

From the question, we are to determine the constant of proportionality from the given table

From the given information, we have that

There is a proportional relationship between x and y

That is,

y ∝ x

Then,

y = kx

Where k is the constant of proportionality

From the table,

When x = 5 pounds, y = $2

Then,

2 = k × 5

k = $2/5pounds  

k = $0.4/pound

k = $0.4 per pound

4.

x is proportional to y

Then,

y = cx

Where c is the constant of proportionality

From the table,

When x = 3 ounces of dark chocolate, y = 9 ounces of almond

Then,

9 = c × 3

c = 9/3

c = 3 ounces of almond / ounces of dark chocolate

c = 3 ounces of almond per ounces of dark chocolate

What is relationship?

The relation in mathematics is the connection between two or more sets of values. Assume that there are two sets of ordered pairs, x and y. If set x and set y are related, then the values of set x are referred to as the domain while the values of set y are referred to as the range.

Given table is

x      1       2        3          4

y      4       1       4/9       1/4.

Given that y is inversely proportional to the square of x.

y∝ 1/x²

y = k/x² where k is proportional constant.

Putting x = 1 and y = 4 in equation y = k/x²:

4 = k/1²

k = 4

Putting x = 2 and y = 1 in equation y = k/x²:

1 = k/2²

k = 4

Putting k = 4 in  y = k/x²:

y = 4/x²

Putting y = 25 in  y = 4/x²

25 = 4/x²

25x² = 4

Divide both sides by 25:

x² = 4/25

The required solutions to the given triangle ABC below as:

(i) sin (B+C/2) = cos (A/2)

(ii) if angle A= 90°, then the value of tan (B+C/2) is is undefined.

Interior angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles.

Given that A, B, and C are interior angles of a triangle ABC.

To solve the question, we would consider trigonometric ratios of complementary angles.

sin (90° - θ) = cosθ

We know that for ΔABC,

∠A + ∠B + ∠C = 180° (Angle sum property of triangle)

∠B + ∠C = 180° - ∠A

On dividing both sides by 2, we get,

(∠B + ∠C)/2 = (180° - ∠A)/2

(∠B + ∠C)/2 = 90° - ∠A/2

Applying sine angles on both sides:

sin {(∠B + ∠C)/2} = sin (90° - ∠A/2)

Since, sin (90° - θ) = cos θ, we get

sin (∠B + ∠C)/2 = cos A/2

(ii)  if angle A= 90°, then find the value of tan (B+C/2)

If cos A/2 = 0 so ∠A = 90°

sin (∠B + ∠C)/2 = cos A/2 = 0

tan (B+C/2) = ∞

Thus, the value of tan (B+C/2) is undefined.

We need to start by choosing some 10 integers so that we can ensure that when they are divided by 11, at least two of the integers will give the same remainder.

The following is the explanation:

If you divide a number by 11, the answer will be a fraction. There are 11 remainders which might occur, which are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

If for example we choose one number and divide it by 11, there is a chance that the remainder may be any of the 11 (0 reminders 1). Therefore, if we choose 10 numbers, we will have the opportunity to pick 10 unique remainders, ranging from 0 to 10.

In conclusion, if we select one more integer, that is we pick 10 integers, then at least two of them would have the same remainder since there are only 10 remainders.

Because of this, we need to choose 10 numbers such that we can guarantee that at least two of them will provide the same remainder when they are divided by 11.

It is better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.

What is the percentage increase?

The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original.

It is generally better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.

This is because the percentage raise you receive is applied to your current salary. If you receive a 3% raise first, your salary will be higher when you receive the 9% raise, so the 9% raise will be applied to a higher base salary. This means that you will receive a larger increase in salary overall if you receive the 9% raise first.

For example, let's say you are currently making $50,000 per year. If you receive a 3% raise followed by a 9% raise, your salary would increase to $51,500 after the first raise and then to $56,365 after the second raise, for a total increase of $6,365.

On the other hand, if you receive a 9% raise followed by a 3% raise, your salary would increase to $54,500 after the first raise and then to $56,365 after the second raise, for a total increase of $5,865.

In this example, you would receive a larger increase in salary overall if you received the 9% raise first. This is because the 9% raise is applied to a lower base salary, resulting in a larger increase in salary overall.

Of course, the actual amount of the raise will depend on your current salary and the percentage of the raise. In general, though, it is usually better to receive a larger percentage raise first, followed by a smaller percentage raise.

Hence, It is better to receive a 9% raise followed by a 3% raise, rather than a 3% raise followed by a 9% raise.
