The point at which the perpendicular bisectors of a triangle's sides come together is known as the circumcenter of that triangle. The line's equation is x=-2.5.

The circumcenter is, in other words, the point at which the bisector of a triangle's sides coincides. P serves to indicate it (X, Y).

This intersection represents the point on the triangle's perimeter. Distance d = (a - ax)2 + (b - bx)2 is the geometry formula for distance. "d" represents the separation between a vertex and the circumference, where x = 1, 2, 3.

The junction of the perpendicular bisectors of each side of the triangle, or the lines that are perpendicular to each side's midpoint, is where the triangle's circumcenter can be located.

To determine it, we locate the intersection of the circumcenter and the first name of the triangle, which is the point at which each line intersects the other

(-4,0) B=(-4,-4) C=(-1,-4) (-1,-4) (-4, -2),

y=-2 is the perpendicular line to AB's midpoint.

The value each segment length in right triangle ABC are AD = 6 units, BC = 4 units, AB = 4√3 units and BD = 2√3 units

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles

Since AC = 8 and CD = 2.

Thus, AD = AC - CD = 8 - 2 = 6 units

sin 30° = BC/AC

0.5 = BC/8

BC = 0.5 × 8

BC = 4 units

AB = √(8²-4²)   (Pythagoras theorem)

AB = 4√3 units

BD = √(4²-2²)   (Pythagoras theorem)

BD = 2√3 units

The value of q in the equation 3x-4=x+q when x=2 is 0.

We can find the value of q in the equation 3x-4=x+q by solving for q:

First, we can substitute the given value of x (x=2) into the equation:

3(2)-4=2+q

Simplifying:

6-4=2+q

2=2+q

Now we can subtract 2 from both sides of the equation:

q = 0

So, the value of q in the equation 3x-4=x+q when x=2 is 0.

Answer: q = 0

Step-by-step explanation:

3x - 4 = x + q

2x - 4 = q

Substitute x = 2 in the equation,

2 x 2 - 4 = q

q = 0

Therefore, the correct answer is 0.

Answer:

y = 2x -2

Step-by-step explanation:

y = mx + b

We need the slope (m) and the y-intercept (b) to write the eqation.

The slope is the change in y over the change in x.  We can see from the table that the y is changing by 2 as the x changes by 1

So the slope is 2/1 which is the same as 2

The slope (m) is 2.

The y-intercept is the place where the line crosses the y axis.  It is at the point (0,b).  When x is zero, what is y?  If we follow the patter and move to the number before x is 1, we get x = 0.  That means that we have to move back 2 units of the y's.  That would be -2.  So the y-intercept is the point (0,-2).

The y-intercept (b) is -2

y = 2x - 2

The dimensions of the sides of the triangular flower bed are 27ft, 54ft and 52ft.

A triangle is simply a two-dimensional polygon with 3 sides and 3 interior angles.

Given the data in the question;

Let the shortest side b x.

Since a triangle has three side, the perimeter of the triangle will be;

Perimeter = side 1 + side 2 + side 3

Plug in the values and solve for x

133 = x + 2x + x +25

133 = 4x + 25

133 - 25 = 4x

108 = 4x

4x = 108

x = 108/4

x = 27

Therefore, the dimensions of the flower bed are;

Shortest side = x = 27ft

Second side = 2x = 2( 27) = 54 ft.

Third side = x + 25 = 27 + 25 = 52 ft

Answer:

To solve this problem, we will use the following steps:

Step 1: Let's assume that the number of quarters is x, and the number of dimes is y

Step 2: We know that the number of dimes is three more than four times the number of quarters, so we can write the equation: y = 4x + 3

Step 3: We also know that Chi has $13.30 in dimes and quarters. Since dimes are worth $0.10 and quarters are worth $0.25, we can write the equation: 0.25x + 0.10y = 13.30

Step 4: Now we have two equations with two unknowns, we can substitute one equation into another to find the value of x and y.

y = 4x + 3

0.25x + 0.10(4x + 3) = 13.30

0.25x + 0.40x + 0.30 = 13.30

0.65x = 13

x = 20

Step 5: We can substitute the value of x in one of the equation, to find the value of y

y = 4(20) + 3

y = 83

Final Answer: Chi has 20 quarters and 83 dimes.

Note: We can check our solution by multiplying the number of quarters by $0.25 and the number of dimes by $0.10 to check if the total money is $13.30 which is true.

The expression √5x × √30x is simplified using the product rule to give 12.25x

Square root of a number can be defined as the inverse operation of the square of a number.

It is the number obtained by finding a number that when squared would give the original number.

Square root is represented using the symbol '√ '. The symbol is called a radical.

Also, the number under the symbol is called the radicand.

To multiply two square roots, we have to multiply the radicands and leave the radical sign.

From the information given, we have;

The given angle 2.59 radian into degree is 148.40°.

What is radian and degree?

While a radian is another unit of measurement that is used to measure angles, a degree is a unit of measurement that is used to measure circles, spheres, and angles. The radian, or one pi radian, is only half the diameter of a circle, which has 360 degrees, or its entire area.

Given:

The angle in radian is 2.59.

We have to convert this angle into degree.

Since, the formula to convert angle θ from radian to degree is,

Radian = [tex]\frac{180}{\pi }[/tex] degree

= 2.59 x (180/π)

= 148.40°

a) The 99% confidence interval for the proportion of all adults in the United States who would have chosen the minimum wage statement is given as follows: (0.3926, 0.4474).

The interpretation is that we are 99% sure that the true population proportion is in this interval.

b) The condition has to be satisfied as the confidence interval is constructed considering an assumption of normality, and by the Central Limit Theorem, at least 10 successes and 10 failures are needed for the sampling distribution of sample proportions to be normal.

A confidence interval of proportions has the bounds given by the rule presented as follows:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

Answer: The formula for the mathematical function that takes as input an RGB color vector ⟨r,g,b⟩ and yields as output the RGB color vector that is the unique shade of gray whose total amount of light (r+g+b) is equal to that of the input is:

(r+g+b)/3, (r+g+b)/3, (r+g+b)/3

Step-by-step explanation: RGB color space is a way to represent colors digitally, where each color is represented by a combination of red, green, and blue values ranging from 0 to 255. To obtain a unique shade of gray whose total amount of light (r+g+b) is equal to that of the input color, we have to set all three color channels to the average value of the red, green and blue values.

To calculate this average value we use the formula: (r+g+b)/3

So the output of the function is ⟨(r+g+b)/3, (r+g+b)/3, (r+g+b)/3⟩ which is the unique shade of gray whose total amount of light is equal to that of the input color.

Note: This is one way to convert color to gray, other methods exist like using luminosity or other weights to RGB channels.

Using the given information, the measure of angle AEB is 62

From the question, we are to determine the measure of angle AEB

From the given information, we have that

Angle A = 86°

Angle C = 110°

Angle D = 40°

First, we will calculate the measure of angle B

A + B + C + D = 360°

86 + B + 110 + 40 = 360 (Sum of angles in a quadrilateral)

B + 236 = 360

B = 360 - 236

B = 124

∴ Angle ABC = 124

Then,

Angle ABC is bisected
