Create an equation to solve for x using the trapezoid midsegment formula:

Answers

Answer:

Equation for x:    3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]

x = 9

CD = 17

GH = 21

Step-by-step explanation:

The midsegment formula for a trapezoid is

GH = [tex]\frac{CD + FE}{2}[/tex]

3x - 6 = [tex]\frac{2x - 1 + 25}{2}[/tex]

6x - 12 = 2x + 24

4x = 36

x = 9

CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17

GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21

If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k

Answers

Answer:

roots: 1 and 3

k = 3

Step-by-step explanation:

2 roots: p and p+2

(x-p) (x-p-2) = x² - 4x + k

x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k

-2 (p+1) = -4

p+1 = 2

p = 1   ... root 1

p' = 1+2 = 3   ... root 2

k = p² + 2p = 3

check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k

Find m ∠ B if mAB = 120° and m ∠ A= 42º.


A)78°
B)80
C)18
D)156

Answers

Answer:

∠B = 78°

Step-by-step explanation:

∠C = 1/2 arc AB = 1/2(120°) = 60°   because it is an inscribed angle

∠B = 180° - 42° - 60° = 78°

The measure of  ∠ B is  78°.

What is inscribed angle?

An inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It can also be defined as the angle subtended at a point on the circle by two given points on the circle.

What is inscribed angle theorem?

The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

According to the question

m ∠ A= 42º.

mAB = 120°

By  inscribed angle theorem :

mAB = 2 m∠C

120° = 2 m∠C

m∠C = 60°

now,

according to the sum of angle of triangle

m ∠ B + m∠C + m ∠ A = 180°    

m ∠ B +60° + 42º= 180°  

m ∠ B = 78°

Hence, the measure of  ∠ B is  78°.

Write the equation of the circle with a center at (11,6) and a radius of 6.

Answers

Answer:

(x-11)^2 + (y-6)^2= 6^2

Step-by-step explanation:

Answer:

(x - 11)² + (y - 6)² = 36

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (11, 6 ) and r = 6, then

(x - 11)² + (y - 6)² = 6² , that is

(x - 11)² + (y - 6)² = 36

Find the equation of the line. Use exact numbers y=, x,+5

Answers

I can't see pictures, so I'll do my best.

y= always stays the same.

To find the slope, or x, you have to start at the y-intercept, and find the number of units up, then right.

For example, y=4/3+6

4/3 is the slope because it goes up 4 units and right 3 units from the y-intercept.

6 is the y-intercept, which is the y-coordinate. It can also be graphed as (0,6).

The FBI started in 1908. It was known as the Bureau of Investigation then. On July 26, 1908, the Attorney General selected ten Special Agents of the Bureau of Investigation. They were called the Special Agent Task Force. In 1933, the Bureaus name was changed to the Division of Investigation. It was changed again in 1935 to the Federal Bureau of Investigation. It is known as that today. All agents carry a special wallet that has their picture in it. They use this wallet to identify themselves to people when they are working. It is called a credential. There are two different kinds of credentials. They change depending on which division in the FBI you work in and your rank as an agent. The FBI has changed what they investigate as the times have changed. In 1908, there were different crimes than the crimes that exist today. Also, there were fewer types of crimes than today. A good example of this is car theft. In 1908, almost no one had a car. As more people bought cars, the number of car thefts increased. Many years ago, the FBI investigated crimes like bank robbery, kidnapping, and car thefts that go across state lines. Today, there are over 350 violations of the law that the FBI investigates. The different violations are broken down into several categories. The FBI looks into violent crime, organized crime, white collar crime, terrorism, foreign counterintelligence, civil rights, and applicant matters. The FBI has many ways of solving those crimes and finding the criminals. One of them is through fingerprint identification. Fingerprints are a great way to tell people apart because everyones fingerprints are unique. This means that no two people in the world have the same fingerprints! Other ways of identifying people, like hair color, height, and weight, may change as a person gets older. Fingerprints stay the same no matter what. There are over 250 million sets of fingerprint records on file. If all the fingerprint cards on file were stacked on top of one another, they would equal 133 stacks, each the size of the Empire State Building! Finding space to keep all of these fingerprint cards is difficult. This is one of the reasons the FBI is now putting cards in a digital format. That means the images can be stored on computers. All fingerprint cards at the FBI are eight-inch squares, a little smaller than a piece of notebook paper, and are thinner than a piece of cardboard. The FBI gets over 37,000 of these fingerprint cards every day, seven days a week! 32% of these cards now come to the FBI as digital images. Not all fingerprint cards on file are of criminals. Some records are civil prints. Civil prints are taken of people who work for the government or apply for a job with the government. Still interested in being an agent?
