a)

circumcenter

b)

incenter

c)

centroid

d)

orthocenter

Answer:
### Circumcircle

**Answer:**

a) circumcenter

**Step-by-step explanation:**

You want to know the name of the point of intersection of the **three perpendicular bisectors** of the sides of a **triangle**.

Each side of a triangle is a chord of the circumscribed circle. The perpendicular bisector of a chord is a line through the center of the circle. Hence the point of concurrency of the perpendicular bisectors of the sides of a triangle is the center of the circumscribed circle.

The name of the center of the circle circumscribing a triangle is "**circumcenter**."

*Additional comment*

When the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse, which is a diameter of the circle.

**Answer:**

The probability that you made this call is **0.8639**.

**Explanation:**

Parameter for you = λ1 = 2

⇒ β1 = 1 / λ1 = 1 / 2 = 0.5

Parameter for Janice = λ2 = 4

⇒ β2 = 1 / λ2 = 1 / 4 = 0.25

Probability that you made a for 0.5 hours or more:

Probability that Janice made a for 0.5 hours or more:

Overall probability that a call was made for 0.5 hours of more

= (0.7 x 0.3679) + (0.3 x 0.1353)

= 0.2981

Probability that you made the given call

= 0.7 x 0.3679 / 0.2981

= 0.8639

After the release of radioactive material into the atmosphere from a nuclear power plant in a country in 2000, the hay in that country was contaminated by a radioactive

isotope (half-life 7 days). If it is safe to feed the hay to cows when 14% of the radioactive isotope remains, how long did the farmers need to wait to use this hay?

The farmers needed to wait approximately days for it to be safe to feed the hay to the cows.

**Answer:**

19.9 days

**Step-by-step explanation:**

The amount remaining after d days is ...

a = (1/2)^(d/7)

We want to find d when a = 0.14

log(a) = (d/7)log(1/2)

d = 7·log(0.14)/log(1/2) ≈ 19.855 ≈ 19.9

**The farmers need to wait about 19.9 days for it to be safe**.

The **statement **that best describes adjacent angles is that adjacent **angles share** a side.

A vertex is where two **non parallel **lines meet.For example a triangle has **3 vertex**.We can also say that vertex is a point where two non parallel lines meet to **form **an angle.

According to the **given** question the best description of adjacent angle is that they share a **side**.

We can say that adjacent **angles **are those angles which are placed **next **to each other.

Adjacent angle also share a **common **vertex but they do not **overlap **each other.

**Answer:**

The correct answer to this would be **D, adjacent angles share a side.**

**Step-by-step explanation:**

Adjacent angles share a common side as well as a common vertex.

O 5x - 32

0 21x + 23

0 5x + 23

O 5x - 17

**Answer:**

5x+23

**Step-by-step explanation:**

3(x+1) - 4(2x-5) + 10x

3x+3 - 8x+20 + 10x

(3x-8x+10x = 5x)

(3+20 = 23)

Therefore, answer is 5x-23. :)
