Arc length and area

Mathematics
1 answer:
IrinaVladis [17]3 years ago
7 0

Answer:

60^\circ

Step-by-step explanation:

Angle ABC is formed by two tangents drawn from point B outside the circle.

The measure of angle ABC is half the difference between the two intercepted arcs.  One of those arcs is arc ADC, the big one with measure 240 degrees.  The smaller arc, closer to point B, is arc AC with measure 120 degrees.

m\angle ABC=\frac{1}{2}(240^\circ - 120^\circ)=60^\circ

To find out more, do an Internet search for "arcs and angles in circles".

The description in lines 20-21 ("temples . . . centers")
Lynna [10]

The correct option is (C) deprecating the appearance and character of many new theaters.

<h3>What is a description?</h3>
  • The pattern of narrative development that aims to bring a place, object, character, or group to life is known as description.
  • Description, along with exposition, argumentation, and narration, is one of four rhetorical modes (also known as modes of discourse).
  • In practice, writing literature that relied solely on one of the four basic modes would be difficult.

  • It has seen a few goods and a lot of bad news theaters, temples to bourgeois muses with all the panache of suburban shopping malls.

Therefore, the correct option is (C) deprecating the appearance and character of many new theaters.

What is the approximate solution to this equation?
Nookie1986 [14]

Answer:

  C.  x ≈ 0.28

Step-by-step explanation:

A graphing calculator solution is attached. It shows ...

  x ≈ 0.28

__

You can divide both sides of the given equation by 5, then take natural logs and divide by 5 again.

  5e^(5x) = 20 . . . . . . given

  e^(5x) = 4 . . . . . . . . divide by 5

  5x = ln(4) . . . . . . . . take natural logs

  x = ln(4)/5 . . . . . . . divide by 5

  x ≈ 0.277259 ≈ 0.28

Identify the vertex, focus, and directrix of the graph. Which of the following equations represents the parabola in the graph?
antoniya [11.8K]

Answer:

Equation: (x-2)^2=16(y-2)

Vertex: (2,2)

Directrix: y=-2

Focus: (2,6)

Step-by-step explanation:

<u>Standard Form of Vertical Parabola:</u>

  • Equation -> (x-h)^2=4p(y-k) where p\neq 0
  • Vertex -> (h,k)
  • Directrix -> y=k-p
  • Focus -> (h,k+p)

We know that our vertex is (h,k) -> (2,2), therefore, we can determine the value of p by selecting a point from the parabola as (x,y):

(x-h)^2=4p(y-k)

(x-2)^2=4p(y-2)

(6-2)^2=4p(3-2)

(4)^2=4p(1)

16=4p

4=p

<u>Therefore:</u>

  • Directrix -> y=k-p -> y=2-4 -> y=-2
  • Focus -> (h,k+p) -> (2,2+4) -> (2,6)

<u>Conclusion:</u>

  • Equation -> (x-2)^2=16(y-2)
  • Vertex -> (2,2)
  • Directrix -> y=-2
  • Focus -> (2,6)
