Step-by-step explanation:

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)

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 probability that both coins will land on heads is 50%. In other words, each coin toss is an independent event and each coin has an equal chance of landing on either heads or tails.

This is because the result of the first coin toss does not influence the outcome of the second coin toss, meaning each toss is an independent event with a 50% chance of landing on heads.The probability that both coins will land on heads is 50%. This is because the result of the first coin toss does not influence the outcome of the second coin toss.

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.

Step-by-step explanation:

Answer: the slope is [tex]\frac{4}{2}[/tex] which can be simplified to just 2.

Step-by-step explanation:

You can use the equation [tex]\frac{y2-y1}{x2-x1}[/tex] to find the slope of a line. In this case, I chose to use the coordinates (-4,0) and (-6,-4), it doesn't matter which you choose as the (x1,y1) and (x2,y2) coordinates. So, [tex]\frac{-4-0}{-6-(-4)}[/tex] becomes [tex]\frac{-4}{-2}[/tex] which is the same as [tex]\frac{4}{2}[/tex], which is equal to 2. you can repeat this with the other points given to check your answer.

The slope of the line passing through the given points is equal to 2 .

The slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate of that line. The slope of a line is the measure of the tangent of the angle made by the line with the x - axis. It is represented by m: m = y₂-y₁ / x₂ - x₁

Given here, are the points P (-10, -12), Q(-8, -8), R(-6, -4),S (-4, 0)

Now the slope of a line is constant for any two points that lie on a line.

therefore, slope of the line that passes through P,Q,R,S  is

m = -8-(-12) /-8-(-10)

    = 2

 or m= 0-(-4) /-4-(-6)

         = 2

clearly the slope is equal to 2 in either case that's because the line passes through all the four points.

Hence,  the slope of the line passing through the given points is equal to 2.

The system of linear equations, y = 2x + 4 ;

2y = x + 6 has a unique solution and it is a consistent system of linear equations.

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 ,

The graph of the first five terms can be seen in the image at the end.

We know that we have an arithmetic sequence:

3, -10, -23, -36

The common difference is what we get when we subtract two consecutive terms, we will get:

d = -36 - (-23) = -3

Then the recursive relation is:

a(n) = a(n - 1) - 13

At the moment we know:

a(1) = 3

a(2) = -10

a(3) = -23

a(4) = -36

Then fifth term will be:

a(5) = a(4) - 13 = -36 - 13 = -49

Now to graph it, we use the "n-th" value as the input, then we need to graph the five points (1, 3), (2, -10), (3, -23), (4, -36), (5, -49).

Given that C is the line segment from (5,4) to (0,0):-

So, our first task is to calculate the line segment

After calculating the line segment, we will be able to calculate the line integral

We know that the equation of line is -

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

So now,

y - 0 = (4 - 0)/ (5 - 0) * (x - 0)

y = 4/5 x

5x - 4y = 0 -----------> (1)

A line integral is used to calculate the area covered by that line

c1 = ∫₀⁴ 5x dx ------> (2)

c2 = ∫₀⁵ -4y dy -----> (3)

c1 = [ 5 x²/2 ]₀⁴ = 5 * ( 4² - 0)/2 = 40

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.

The statement would no longer be true if you did not flip the signs.

Example: 1 < x < 2 multiplied by (-1) equals -2 < x < -1, because you can't have a number that is greater than -1, and less than -2 at the same time.

so total amount of mirepoix that required in the solution is = [tex]\frac{x}{100} *1 pound[/tex]

so x/100 = 1 gallon / pound

we will use this equation for further calculation

let we need y pounds of mirepoix to make 31/2 gallon of soup  ans we know that x% of mirepoix is required for this solution.

so [tex]\frac{x}{100} * y = 31/2[/tex]
