Answer: The distance between the two parallel lines is 11/12.
Step-by-step explanation:
The distance between two parallel lines can be found by calculating the difference between the y-intercepts of the two lines. In this case, the y-intercept of the first line is (-1/4,0), and the y-intercept of the second line is (-7/6,0). The difference between these y-intercepts is (-1/4 - (-7/6)) = 11/12. Therefore, the distance between the two parallel lines is 11/12.

Step-by-step explanation:
a pentagon with 5 sides of equal length and 5 interior angles of equal measure is inscribed in a circle. is the perimeter of the pentagon greater than 26 centimeters?
the perimeter of the pentagon greater than 26 centimeters is given by
23.51
Given that a pentagon with 5 sides of equal length and 5 interior angles of equal measure is inscribed in a circle
The circle has area of 16 pi sq cm.
Hence radius of circle = 4 cm
The pengagon each side would be a chord of equal length subtending angle 72 at the centre.
visualize the triangle made by one side of pentagon with centre. This is isosceles with angles 72, 54 and 54
Use sine angle for this triangle.
, where R = radius =4 and s = side of pentagon.
s= 4.702
Perimeter = 5s = 23.5114 cm
Perimeter not greater than 26 cm.
If origin is at the centre then two vertices would be (4,0) (4cos 72, 4sin72),(4cos 144, 4 sin 144) and so on.
Longest diagonal = distance between (4,0) and (4cos 144, 4 sin 144)
= (-3.236, 2.351) and (4,0)

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

(ii) if angle A= 90°, then find the value of tan (B+C/2)
Answer:
ok i can do it if u want then see my m.s.g
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.
What are Interior Angles?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.

Would you rather receive a 3% raise followed by a 9% raise or a 9% followed by a 3%
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.

What is a dilation transformation?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)

Describe how to write 4x^2 + 8x - 10 = 0 in vertex form
Answer:
(2x + 1)^2 = 7
Step-by-step explanation:
To write the quadratic equation 4x^2 + 8x - 10 = 0 in vertex form, we need to first complete the square. To do this, we need to add and subtract the same value to the quadratic term and the linear term so that the resulting quadratic has the form (x - h)^2 = k.
In this case, we need to add and subtract the square of half of the coefficient of the linear term, which is 8/2 = 4. This gives us the equation:
4x^2 + 8x + 4 - 4 - 10 = 0
This simplifies to 4(x^2 + 2x + 1) - 14 = 0, which can be rewritten as (2x + 1)^2 - 7 = 0.
To put this in vertex form, we need to rewrite the right side of the equation as a perfect square, so we add 7 to both sides to get (2x + 1)^2 = 7.
Then, we take the square root of both sides to get 2x + 1 = ±√7. We can then solve for x to get x = -1/2 ± √7/2.
Therefore, the equation 4x^2 + 8x - 10 = 0 can be written in vertex form as (2x + 1)^2 = 7.

The temperature at 4pm is 43 degrees. Throughout the night it steadily falls 6 degrees.
What is the rate of change in this situation?
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.
Julie is given the data point (6, 7) as a point on the profit equation that she must create. Her boss mentioned that the last equation that
they used was y = 2x+3. If Julie wants to write the new equation that is parallel to the old equation, what would her new equation look
like?
y=6x+7
y=2x-5
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.

What is linear System of Equations and it's solution?An ordered pair that satisfies all equations of the system is the solution of the system. A system of linear equations can have one solution, no solution, or an infinite number of solutions. The systems of equations can be classified according to the number of solutions. If a system has at least one i.e unique solution, it is called consistent. We have, the system of equations is
y = 2x + 4 => 2x - y + 4 = 0 --(1)
2y = x + 2 => x - 2y + 6 = 0 --(2)
Comparing the equation (1) with a₁x + b₁y + c₁=0
and equation(2) with a₂x + b₂y + c₂=0
We get, a₁ = 2 , a₂= 1 , b₁ = -1 , c₁= 4 , b₂= -2 , c₂ = 2
Now, compute the ratio of coefficients of variables .
a₁/a₂ = 2/1 , b₁/b₂ = -1/-2 = 1/2 , c₁/c₂= 4/6 = 2/3
=> a1/a2 ≠ b1/b2 ,

how many integers must you pick in order to be sure that at least two of them have the same remainder when divided by 11?
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.
